Reflux Nephropathy and its Management

Recurrent urinary tract infections during childhood are most likely caused by reflux nephropathy, which can lead to renal scarring, resistant hypertension, and chronic renal failure over time. Early intervention is crucial, including investigation in childhood, antibiotics, and referral to a urologist to identify and correct any anatomical abnormalities. Chronic interstitial nephritis caused by analgesic use is unlikely in this case, as the patient’s knee injury was likely acute. IgA nephropathy typically presents after respiratory tract infections, while post-streptococcal glomerulonephritis occurs 10-14 days after streptococcal pharyngitis. Essential hypertension is diagnosed based on the absence of an underlying cause. Proper management of reflux nephropathy can prevent long-term complications and improve the patient’s quality of life.

Bacterial Causes of Pneumonia

Pneumonia is a respiratory infection that can be caused by various bacteria. The most common organism associated with pneumonia is Streptococcus pneumoniae, which can be identified by its Gram-positive spherical shape and chain formation. It is also known for causing rust-coloured sputum. Staphylococcus aureus, another Gram-positive bacterium, grows in clusters rather than chains. Klebsiella pneumoniae, a Gram-negative rod-shaped bacterium, is commonly associated with aspiration pneumonia. Haemophilus influenzae, a small Gram-negative rod-shaped bacterium, is often linked to exacerbation of COPD. Streptococcus pyogenes, a Gram-positive spherical bacterium that aligns in clusters, does not typically cause pneumonia and is associated with complete haemolysis on a blood agar plate. Knowing the characteristics of these bacteria can aid in the diagnosis and treatment of pneumonia.

Skin Disorders

Toxic shock syndrome (TSS) is a condition caused by Staphylococcus aureus. Half of the cases of TSS are linked to tampon use in women, while the other half result from localized infections. The initial symptom is often sudden and severe pain, which is followed by tenderness or physical findings. In some cases, patients may experience an influenzae-like syndrome, which includes fever, chills, myalgia, nausea, vomiting, and diarrhea. Fever is the most common early sign, but hypothermia may be present in patients with shock. Therefore, TSS should always be considered in young women presenting with these symptoms.

Toxic epidermal necrolysis is a life-threatening skin disorder that causes blistering and peeling of the top layer of skin. Staphylococcal scalded skin syndrome is another skin infection that is characterized by peeling skin. The most common symptoms include an erythematosus painful infection site, blistering, fever, chills, weakness, fluid loss, and peeling of the top layer of skin in large sheets. Epidermolysis bullosa is a group of diseases that cause blister formation after minor injury to the skin. This family of disorders, most of which are inherited, ranges in degrees of severity from mild to severely disabling and life-threatening diseases of the skin.

Syndromic Management for Vaginal Discharge

When laboratory support is not available, the World Health Organisation recommends syndromic management based on signs and symptoms alone. This means that all possible conditions should be treated, as vaginal discharge is not a reliable indicator of the presence of a sexually transmitted infection (STI).

Trichomoniasis is the most common non-viral STI worldwide and is more prevalent in less advantaged women in affluent countries. However, the possibility of Chlamydia trachomatis and gonorrhoeae depends on a risk assessment based on local factors.

In summary, when laboratory support is not available, syndromic management should be used for vaginal discharge.

Isoniazid Monotherapy for TB Prevention

Isoniazid monotherapy is a treatment used to prevent active tuberculosis in individuals who have been exposed to M. tuberculosis. However, it is important to note that isoniazid-induced hepatitis can occur in approximately 1% of patients, with a higher risk in those over the age of 35. The risk of hepatitis is less than 0.3% in patients under 20 years old, but increases to 2-3% in individuals over 50 years old.

Aside from hepatitis, other side effects of isoniazid therapy include peripheral neuritis, which can be prevented by taking pyridoxine prophylactically. Additionally, a systemic lupus erythematosus (SLE)-like syndrome may also occur. It is important for healthcare providers to monitor patients closely for any adverse reactions while on isoniazid therapy.

• Ciprofloxacin is a well-tolerated antibiotic with broad action, but it can reduce intestinal flora and increase the risk of tendon rupture.
• Azithromycin is a macrolide antibiotic used for respiratory conditions, with potential drug interactions.
• Alendronic acid is a bisphosphonate used for bone protection, but can cause gastrointestinal side effects and musculoskeletal symptoms.
• Calcium supplements are not directly linked to tendon damage, but may contribute to calcific tendonitis.
• Creon is a pancreatic enzyme preparation used for cystic fibrosis patients, without known musculoskeletal side effects.

Distinguishing Between Measles and Other Viral Infections

Measles, a highly contagious viral infection, is often mistaken for other viral illnesses such as rubella, Kawasaki disease, mumps, and parvovirus B19. However, there are distinct differences in their clinical presentations. Measles is characterized by cough, coryza, and conjunctivitis, along with the presence of Koplik spots on the buccal mucosa. Rubella, on the other hand, presents with low-grade fever, conjunctivitis, and an erythematosus rash, but without Koplik spots. Kawasaki disease is an idiopathic vasculitis that affects young children and is associated with fever, inflammation of the mouth and lips, and cervical lymphadenopathy. Mumps, caused by a paramyxovirus, typically affects the salivary glands and is not associated with a rash. Parvovirus B19, also known as fifth disease, causes an erythematosus rash on the cheeks and can also cause a morbilliform rash, but without Koplik spots. Therefore, recognizing the presence of Koplik spots is crucial in distinguishing measles from other viral infections.

Distinguishing Neurodegenerative Diseases: A Case Study

A patient presents with rapidly progressive dementia, imbalance leading to falls, and myoclonus. The most likely diagnosis is Creutzfeldt–Jakob disease (CJD), a devastating prion disease without cure. Magnetic resonance imaging (MRI) is preferred for diagnosis, as CT head is ineffective.

Vascular dementia, another common cause of cognitive impairment, typically has a slower and stepwise onset in patients with a significant vascular history. A CT head would likely identify existing small vessel disease in the brain of a patient with vascular dementia.

Huntington’s disease, characterized by abnormal movements and cognitive impairment, is not the most likely diagnosis due to the rapid progression and lack of family history.

Lewy body dementia, which features visual hallucinations and Parkinsonian symptoms, usually presents over a longer period of time.

Motor neuron disease, which includes weakness and fasciculations, is unlikely due to the absence of weakness in this presentation. Frontotemporal dementia may rarely develop in motor neuron disease, but it is a slowly progressive phenomenon, unlike the rapid deterioration in this case.

HAART and its Effects on CD4 and Platelet Counts

Treatment with highly active antiretroviral therapy (HAART) has been initiated between the first and second test results. This therapy involves a combination of three or more antiretroviral agents from different classes, including two nucleoside analogues and either a protease inhibitor or a non-nucleoside reverse transcriptase inhibitor. The use of HAART has resulted in an increase in both CD4 count and platelet count.

However, antiretroviral therapies can also cause anaemia in HIV-positive patients, with zidovudine (AZT) being the most common culprit due to its bone marrow suppression effects. In severe cases, patients may require blood transfusions. Macrocytosis, or the presence of abnormally large red blood cells, is a common finding in patients taking AZT and can be used as an indicator of adherence to therapy.

Anthrax: Types, Symptoms, and Treatment

Anthrax is a bacterial infection caused by Bacillus anthracis, a spore-forming bacterium. It is a rare but serious disease that can be acquired through contact with infected animals or contaminated animal products. There are three main types of anthrax: cutaneous, inhalation, and intestinal.

Cutaneous anthrax is the most common type, accounting for 95% of cases. It is caused by direct contact with the skin or tissue of infected animals. The symptoms start with an itchy pimple that enlarges and eventually forms a black eschar. Inhalation anthrax, on the other hand, is caused by inhaling anthrax spores from infected animal products such as wool. The initial symptoms are similar to a cold, but respiratory failure may develop two to four days later. Intestinal anthrax is the rarest form and is caused by swallowing spores in contaminated meats. Symptoms include severe abdominal pain, nausea, and bloody diarrhea.

Antibiotics are used to treat all three types of anthrax. It is important to start treatment as soon as possible after exposure to ensure maximum efficacy. The anthrax vaccine can also be given in combination with antibiotics. the types, symptoms, and treatment of anthrax is crucial in preventing and managing this serious disease.

Hepatotoxicity in Antituberculous Treatment

Hepatotoxicity, or liver damage, is a common occurrence in antituberculous treatment. To prevent further complications, the Joint Tuberculosis Committee of the British Thoracic Society recommends that liver function should be checked before starting treatment for clinical cases. This is to ensure that the liver is healthy enough to handle the medication and to monitor any changes in liver function during treatment. By doing so, healthcare professionals can adjust the treatment plan accordingly and prevent further liver damage. It is important to prioritize liver function monitoring in antituberculous treatment to ensure the safety and well-being of patients.

Infectious Diseases and Their Modes of Transmission

Children who have chicken pox and measles should be kept away from others as there is a high chance of spreading the infection to others. This is because these diseases are highly contagious and can easily spread from one person to another. It is important to isolate these children to prevent the spread of the disease.

Post streptococcal GN and rheumatic fever are caused by immune complexes that develop after an initial infection. These diseases are not contagious and cannot be spread from one person to another. However, it is important to treat the initial infection to prevent the development of these diseases.

Herpetic gingivostomatitis is a disease that is spread through direct contact with infected secretions. This means that the disease can be transmitted when infected secretions come into contact with the skin of an uninfected person. There is no risk of aerosol spread, which means that the disease cannot be spread through the air.

HSP is a disease that is not infectious and cannot be spread from one person to another. This disease is caused by an abnormal immune response and is not contagious.

Differentiating gonorrhoeae from Other Infections

gonorrhoeae is a common sexually transmitted infection that can cause urethritis and arthritis. When someone returns from an area with a high prevalence of gonorrhoeae, they may experience symptoms such as a purulent discharge, fever, and joint pain. This is not a reactive arthritis because the patient has both urethritis and arthritis at the same time, and is pyrexial during the current illness.

The acute monoarthritis is a manifestation of disseminated gonococcal infection, which can be confirmed through a Gram stain that shows intracellular Gram negative diplococci. While reactive arthritis can occur after gonorrhoeae, it typically presents as a polyarthritis and has a lag of one to three weeks from the time of the initial disease.

Chlamydial infection, on the other hand, does not usually cause a purulent discharge and symptoms usually occur slightly longer after exposure than with gonorrhoeae. Pyelonephritis presents with fever and pain in the renal angles, while trichomoniasis is much less common than gonorrhoeae and does not usually present with arthritis. By the differences between these infections, healthcare providers can accurately diagnose and treat patients.

Drug Reaction with Atazanavir and Indinavir

The use of protease inhibitors such as atazanavir and indinavir can lead to unconjugated hyperbilirubinemia, which is characterized by elevated levels of bilirubin in the blood. This condition was observed in a patient who had normal renal function and mildly raised liver enzymes. The reaction is usually benign and reversible upon discontinuation of the drug. The mechanism of this drug reaction is competitive inhibition of the UGT1A1 enzyme. Individuals with Gilbert’s syndrome are more susceptible to this reaction.

Other drugs used in the treatment of HIV/AIDS have different side effect profiles. Nevirapine can cause hepatitis, which is characterized by elevated liver enzymes. Stavudine can cause peripheral neuropathy and pancreatitis, but it is being phased out of treatment regimens. Tenofovir can lead to renal dysfunction, which was not observed in this patient. Zidovudine can cause anemia, hepatitis, and myopathy, among other side effects.

In conclusion, the patient’s presentation of unconjugated hyperbilirubinemia is most likely due to the use of atazanavir or indinavir. Discontinuation of the drug is usually sufficient to reverse the condition. Other drugs used in the treatment of HIV/AIDS have different side effect profiles and should be considered when evaluating patients for drug reactions.

Mycoplasma pneumonia commonly affects individuals aged 15-30 years and presents with systemic upset, dry cough, fever, myalgia, and arthralgia. It can also cause extrapulmonary manifestations such as haemolytic anaemia, renal failure, hepatitis, myocarditis, meningism, transverse myelitis, cerebellar ataxia, and erythema multiforme. Haemolysis is associated with the presence of cold agglutinins. Diagnosis is based on the demonstration of anti-mycoplasma antibodies in paired sera.

Understanding Hepatitis B Serology Results

Hepatitis B is a viral infection that can cause liver damage and even liver cancer. Vaccination is the best way to prevent infection, but it’s important to understand the results of hepatitis B serology tests to determine if someone is immune, currently infected, or susceptible to infection.

Vaccinated against infection: This result indicates that the patient has previously been vaccinated with hepatitis B and is now immune to infection.

Current chronic infection: A positive HBsAg, anti-HBc, and positive IgG anti-HBc result would indicate a current chronic infection. However, the picture shown represents a vaccinated individual.

Current acute infection: A positive HBsAg, anti-HBc, and IgM anti-HBc result would indicate a current acute infection. However, the picture shown represents a vaccinated individual.

Resolved infection: A positive anti-HBs and anti-HBc result, in addition to a negative HBsAg result, would indicate a resolved infection.

Susceptible to infection: A completely negative serology result would indicate that the patient is susceptible to infection and should consider vaccination.

Hepatitis B Vaccine in the UK

Although the risk of hepatitis B is low in the UK, certain individuals are considered to be at high risk and are offered the vaccine. These high-risk groups include individuals who inject drugs or have a partner who injects drugs, those who receive regular blood transfusions, people with chronic liver disease, close family or sexual partners of someone with hepatitis B, and individuals traveling to high-risk countries.

In the case of a patient whose partner has tested positive for the surface antigen (HBsAg), indicating that they are infected with hepatitis B, the patient may not require post-exposure treatment if they plan on having regular unprotected sexual intercourse. In this situation, the best course of action would be to receive the hepatitis B vaccine alone. It is important for individuals in high-risk groups to consider getting vaccinated to protect themselves against this potentially serious infection.

Management of Varicella in Pregnancy

Explanation:
When a pregnant woman presents with a vesicular pruritic rash, it is important to consider the possibility of varicella zoster virus infection. Varicella is a teratogenic virus that can harm the fetus, so prompt management is necessary. The first step is to check the woman’s immune status by testing for varicella antibodies. If the results are not available within two working days, referral to secondary services for prophylaxis should be considered. Watching and waiting is not appropriate in this situation. Administering a varicella zoster vaccine is not recommended due to the theoretical risk to the fetus. Immunoglobulins for rubella are not indicated. acyclovir may be used for symptomatic patients, but informed consent is required as the evidence for its safety in pregnancy is not strong. Overall, prompt and appropriate management is crucial in protecting the health of both the mother and the fetus.

Common Pathogens in Acute Pyelonephritis

Acute pyelonephritis is commonly caused by Escherichia coli, which accounts for more than 80% of cases. Other pathogens that can cause this condition include Enterococcus faecalis, Klebsiella, and Proteus species. The infection typically begins in the bladder and then spreads to the renal parenchyma. At first, the bacteria multiply within the tubules. However, within 48 hours, damage to the tubular epithelium begins to occur.

Rabies and Post-Exposure Treatment

Rabies is a severe viral infection that affects the blood and central nervous system. It is a zoonotic disease, meaning it is transmitted from animals to humans. Symptoms of rabies in humans include fever, itch at the site of infection, hydrophobia, and changes in personality, including aggressive behavior. The World Health Organization (WHO) has categorized three types of contact that determine the need for post-exposure treatment.

Category I contact involves touching or feeding animals or licks on the skin, which requires no treatment. Category II contact includes nibbling of uncovered skin, minor scratches or abrasions without bleeding, and licks on broken skin, which requires immediate vaccination. Category III contact involves single or multiple transdermal bites or scratches, contamination of mucous membrane with saliva from licks, or exposure to bat bites or scratches, which requires immediate vaccination and administration of rabies immune globulin.

It is crucial to note that all bites and wounds require immediate and thorough washing and flushing. Post-exposure prophylaxis is used when there are no symptoms, as once symptoms develop, rabies is almost always fatal, and treatment is based on symptom control. This case describes a category III contact, and the correct treatment is immediate vaccination and administration of rabies immune globulin.

HIV Seroconversion Illness: Diagnosis and Differential Diagnosis

HIV-related seroconversion illness is a non-specific illness that occurs between one to six weeks following infection. It often mimics infectious mononucleosis but may have additional signs such as oral candidiasis or CNS symptoms. The best way to diagnose acute infection is by the presence of p24 antigen or HIV RNA by PCR. Malaria is less likely in this case than HIV, and stool culture would be useful in the diagnosis of gastroenteritis but is unlikely to be the cause of symptoms in this case. A CT chest, abdomen, and pelvis is non-specific and would not yield the diagnosis. A genital swab would be of benefit if there were suspicions of other sexually transmitted infections, but the symptoms and timing of onset in this case clearly point towards HIV seroconversion. It is important to consider HIV testing and prevention in patients with risk factors for infection.

Oral Candidiasis and its Association with Immune System Defects

Oral candidiasis, a fungal infection in the mouth, is a concerning condition in young healthy individuals as it may indicate an underlying defect in the immune system. Further investigation is necessary to identify the root cause of the infection. In London, men who have sex with men have a high prevalence of HIV, which is a likely diagnosis in such cases. HIV weakens the immune system, making individuals more susceptible to infections and other health complications.

Apart from HIV, other immune system defects may also lead to oral candidiasis. Recurrent attacks of shingles in a young person may also indicate a weakened immune system. Additionally, HIV infection is a predisposing factor for deep vein thrombosis (DVT), a condition where blood clots form in the veins deep within the body. Therefore, it is crucial to investigate the underlying cause of oral candidiasis and other related conditions to ensure timely diagnosis and appropriate treatment.

Overall, oral candidiasis is a red flag for immune system defects, and healthcare professionals should be vigilant in identifying and addressing the root cause of the infection.

Antibiotic Recommendations for Urinary Tract Infection in Children

When it comes to treating urinary tract infections in children, it is important to choose an antibiotic that has a low potential for resistance. According to the NICE guidelines on Urinary tract infection in children (CG54), cephalosporin or co-amoxiclav are recommended options. On the other hand, quinolones and tetracyclines are not recommended for this age group. While amoxicillin and trimethoprim are potential options, they also carry the risk of resistance. Therefore, it is crucial to carefully consider the choice of antibiotic to ensure effective treatment and prevent the development of antibiotic resistance.

Japanese Encephalitis: A Viral Infection Endemic in Asia

Japanese encephalitis is a type of RNA virus that is commonly found in India, East Asia, Malaysia, and the Philippines. Interestingly, previous exposure to other viruses in the Flavivirus family, such as dengue, can actually provide some protection against serious illness or death from Japanese encephalitis. This means that individuals who have been infected with dengue in the past may have a lower risk of severe symptoms if they contract Japanese encephalitis.

Despite being endemic to certain regions, Japanese encephalitis can still affect travelers who spend only short periods of time in these areas. Additionally, the virus can be transmitted from mother to fetus during pregnancy.

Fortunately, there is an immunization available for travelers who may be at risk of contracting Japanese encephalitis. It is important for individuals traveling to endemic areas to take precautions and consider getting vaccinated to protect themselves from this potentially serious viral infection.

Likely Diagnosis of Hepatitis in a Male Patient

Although hepatitis can be caused by cytomegalovirus (CMV) and Epstein-Barr virus (EBV), it is unlikely that these viruses are the cause of hepatitis in a male patient over the age of 55. However, hepatitis A is a possible diagnosis, especially in men who have sex with men, despite no history of overseas travel. While hepatitis C can also be spread sexually, its prevalence among men who have sex with men is lower than that of hepatitis B. Additionally, hepatitis B is more easily transmitted through sexual contact, making it the more likely diagnosis in this case. It is important to note that there is a 5-10% chance that the patient may become a chronic carrier.

Adult Onset Still’s Disease

Adult onset Still’s disease is a type of inflammatory disorder that affects young adults. Its exact cause and development are still unknown, but it is characterized by various symptoms such as fever, rash, joint pain, and organ enlargement. The disease can have systemic exacerbations and chronic arthritis, with periods of remission in between. To diagnose adult onset Still’s disease, a person must have at least five criteria, including two major criteria such as high fever lasting for a week or longer, joint pain lasting for two weeks or longer, rash, and abnormal white blood cell count. Minor criteria include sore throat, lymph node or spleen swelling, liver problems, and the absence of rheumatoid arthritis.

It is important to note that mildly raised ASO titres may be present in inflammatory or infective conditions, but an ASO titre of at least 500-1000 is expected in active acute rheumatic fever. Additionally, an ejection systolic murmur may be caused by the hyperdynamic circulation in adult onset Still’s disease, unlike acute rheumatic fever or acute bacterial endocarditis, which cause acute valvular regurgitation and result in pan-systolic or early-diastolic murmurs. Lastly, bacterial endocarditis does not cause the pink rash associated with adult onset Still’s disease.

Common Viral Infections and Their Oral Manifestations

Herpes simplex virus, Parvovirus B19, Coxsackie A16, Molluscum contagiosum, and Varicella-zoster are all common viral infections that can cause various oral manifestations. Herpes simplex virus can cause gingivostomatitis, which can lead to dehydration and require treatment with acyclovir. Parvovirus B19 can result in ‘slapped cheek syndrome’ with a maculopapular rash and non-specific viral symptoms. Coxsackie A16 can cause hand, foot and mouth disease with vesicular and ulcerative oral lesions and macular lesions on the hands and feet. Molluscum contagiosum can cause papular lesions with a central dimple, but rarely in the oral cavity. Varicella-zoster can cause chickenpox with itchy, papular lesions progressing to vesicles, but blisters in the mouth are less common. Understanding these viral infections and their oral manifestations can aid in diagnosis and treatment.

Bacterial Causes of Gastroenteritis: Yersinia, Vibrio, E. coli, Campylobacter, and Salmonella

Gastroenteritis is a common condition caused by various bacterial pathogens. Yersinia enterocolitica is one such pathogen that can cause invasive gastroenteritis, leading to mesenteric lymphadenitis and erythema nodosum. Vibrio vulnificus is another Gram-negative bacterium that causes gastroenteritis and skin blisters after consuming contaminated oysters, with chronic liver disease patients at higher risk. Escherichia coli has several pathogenic strains, including enterotoxigenic, enteropathogenic, enteroinvasive, and enterohaemorrhagic, each causing different types of gastroenteritis. Campylobacter is the most common cause of bacterial gastroenteritis worldwide, with invasive symptoms and often bloody stool. Salmonella, a non-lactose fermenter, can also cause gastroenteritis and diarrhea, usually non-bloody. Understanding the different bacterial causes of gastroenteritis is crucial for proper diagnosis and treatment.

The patient has Kaposi’s sarcoma, which is caused by human herpesvirus 8. This condition can be the first presentation of AIDS in some HIV patients and is more common in males and men who have sex with men. The skin lesions appear as red-purple papules or plaques and can also be found on mucous membranes. Kaposi’s sarcoma mainly affects the skin, but it can also affect the lungs and gastrointestinal tract. Symptoms of pulmonary Kaposi’s sarcoma include cough, shortness of breath, and haemoptysis, while gastrointestinal involvement can cause intestinal obstruction.

CMV infection can occur as reactivation or primary infection, usually in those with low CD4+ counts. In the immunocompromised, it can present with chorioretinitis, encephalitis, pneumonitis, or gastrointestinal disease. HPV is a common virus that causes genital warts, verrucas, and warts on the lips/oral mucosa. It is also a major risk factor for cervical and anal cancers. In immunosuppressed patients, the severity of HPV symptoms and risk of cancer are increased. HSV 1 and 2 are common viruses that can cause oral and genital herpes. In immunosuppression, these viruses may reactivate more frequently and cause more severe symptoms. Cryptococcus neoformans is a fungus that can cause opportunistic infections in AIDS, mostly causing fungal pneumonia and subacute meningitis, but it does not typically cause skin lesions.

Common Causes of Gastrointestinal Infections

Gastrointestinal infections can be caused by a variety of bacteria and viruses. Among the most common are Clostridium difficile, Salmonella spp., Norovirus, Escherichia coli, and Campylobacter spp.

Clostridium difficile is a spore-forming bacterium that causes pseudomembranous colitis, a form of colitis associated with antibiotic treatment. It produces toxins that damage the mucosal lining of the bowel, leading to diarrhea. Risk factors for developing C. difficile-associated diarrhea include age, antibiotic treatment, exposure to infected persons, and hospitalization.

Salmonella spp. are associated with infections of the gastrointestinal tract and diarrhea. Infection is mostly associated with eating undercooked meat, poultry, eggs, or egg products.

Norovirus is the most common viral gastroenteritis in the UK and spreads quickly within a contaminated environment. It is often seen in hospital wards and care homes.

Escherichia coli is associated with infections of the gastrointestinal tract and can cause severe diarrhea. It is most commonly associated with ingestion of contaminated water, unpasteurized milk or cheese, and undercooked beef.

Campylobacter spp. are a common cause of gastroenteritis, mostly associated with ingestion of contaminated food in the form of raw poultry and unpasteurized milk products.

It is important to identify the causative organism early and treat it according to local treatment guidelines to prevent complications such as toxic megacolon, bowel perforation, septicemia, and death. All confirmed cases of gastrointestinal infections must be reported to Public Health.
