    Study Notes

    Bacterial Foodborne Illnesses

    • Staphylococcal Food Intoxication: Caused by Staphylococcus aureus, which produces enterotoxins that cause vomiting, diarrhea, and abdominal cramps within 1-6 hours of consuming contaminated food.
    • Botulism/Clostridium Botulism Intoxication: Caused by Clostridium botulinum, a Gram-positive bacterium that produces neurotoxins, causing symptoms such as difficulty swallowing, muscle weakness, and respiratory failure.
    • Clostridium difficile-Associated Diarrhea: Caused by Clostridium difficile, which produces toxins that cause diarrhea, colitis, and pseudomembranous colitis.

    Zoonotic Bacterial Infections

    • Salmonellosis/Salmonella Gastroenteritis: Caused by Salmonella spp., which causes diarrhea, fever, and abdominal cramps within 12-72 hours of consuming contaminated food and water.
    • Typhoid Fever: Caused by Salmonella Typhi, which causes fever, headache, and abdominal pain within 1-3 weeks of consuming contaminated food and water.
    • Shigellosis/Bacillary Dysentery: Caused by Shigella spp., which causes dysentery, diarrhea, and abdominal pain within 1-7 days of consuming contaminated food and water.

    Viral Gastroenteritis

    • Hepatitis A: Caused by Hepatitis A virus, which causes fever, nausea, vomiting, and jaundice within 15-50 days of consuming contaminated food and water.
    • Viral Gastroenteritis/Stomach Flu: Caused by various viruses such as Norovirus, Rotavirus, and Adenovirus, which cause diarrhea, vomiting, and abdominal pain.

    Parasitic and Prion Diseases

    • Giardiasis: Caused by Giardia lamblia, a protozoan parasite that causes diarrhea, abdominal cramps, and weight loss within 1-2 weeks of consuming contaminated water.
    • Amoebiasis/Amoebic Dysentery: Caused by Entamoeba histolytica, a protozoan parasite that causes dysentery, diarrhea, and abdominal pain.
    • Beef Tapeworm Infection: Caused by Taenia saginata, a parasitic worm that causes intestinal obstruction, diarrhea, and weight loss.
    • Prion Diseases: Caused by abnormally folded protein particles, which cause brain damage and neurodegenerative diseases such as Bovine Spongiform Encephalopathy (BSE) and Creutzfeldt-Jakob disease.
