BIOL241 Lecture Notes - Lecture 8: Flaccid Paralysis, Potato Salad, Enterotoxin
Document Summary
Acute inflammation of the gastroinitestinal tract ( enteric tract, gi tract: especially small intestine, or large intestine (enterocolitis, diarrhea: a result of. Decreased absorption of fluid from the intestinal tract. An increased secretion of fluids of derived from blood into the intestinal tract: enterotoxins: toxins that affect gi tract: Typically exotoxins (protein excreted from bacterial cells) Stimulate secretion of water and salts intestinal lumen: food poisoning (intoxication): illness that results from ingestion of foods containing preformed microbial toxins, food infection: active infections resulting from ingestion of pathogen-contaminated foods. Staphylococcal food poisoning: staphylococcus aereus: small gram positive cocci. Will grow under aerobic and anaerobic conditions. Do not compete well with other microorganisms in food: enterotoxins: several types (a, b1, c1, c2, d, e) Type a most frequently associated with food poisoning enta gene is chromosomal, types b, c encoded on mobile genetic elements functions as superantigens: active general inflammatory response in intestine massive fluid loss: symptoms.
