Bacterial Diseases and Intoxications of the GI tract
| Question | Answer |
|---|---|
| Bacillary dysentary | bloody diarrhea caused by Shigella--raspberry jam stool--contains blood and sheets of pus--great numbers of bacilli in stool |
| Bacteriuria | bacteria in the urine |
| Botulinum toxin | so potent that detectable growth (by odor or bulging cans) need not be present for intoxication to result--one ounce can kill population of U.S. |
| Botulism | occurs when canned foods ingested that were not adequately heated to kill all clostridium botulinum spores--absorbed in bloodstream--acts on nerves--sx dizziness, blurred vision, nausea, abd. pain--paralysis, resp. paralysis cause of death |
| Brucellosis | caused by Brucella--in animals and are a common cause of abortion in cattle, swine, sheep, and goats--humans get from handling these animals, their meat, or dairy products--incubation 2-4 weeks--fever, anorexia, abd pain, diarrhea, nausea--fever up/down |
| Cholera | disease caused by Vibrio cholerae--comma-shaped organism--rice water stool, watery appearance with small granules that look like rice grains--massive looses of electrolytes (20L/day)--measure fluid lost and replace with that much volume with electrolytes |
| Coliform | Escherichia coli--common inhabitant of colon--gram neg. bacterium--contains endotoxin--lipid A of LPS--induces fever when bacteria invade--transmission: feces, flies, fingers, foodd and fomites--sanitation is key |
| Cystitis | inflammation of the bladder |
| Dysentery | watery diarrhea with blood, mucus, pain, and fever |
| Enterotoxin | acid stable--E.coli--causes bloody diarrhea, kidney failure, coma and death--transmission--fecal-oral--ABT not useful |
| Food poisoning | enterotoxin secreted by many strains of staphylococcus--lasts 1-6 hours--projectile vomiting |
| Gastritis | inflammation of the stomach |
| Gastroenteritis | inflammation of the stomach and intestinal lining |
| Intoxication | disease produced by a toxin |
| Pure toxemia | stomach acid kills organisms |
| Rose spots | skin hemorrhages that come with typhoid fever |
| Salmonellosis | less severe form of diarrhea--salmonella--transmitted from reptiles--gram-negative rod |
| Stepladder fever | fever that goes up and down each day--typhoid fever |
| Traveler's diarrhea | seen in people who travel to foreign countries and contact E. coli with different enterotoxin |
| Typhoid fever | gran-neg rod--human to human spread--salmonella typhi--intestinal ulcerations, bloody stools, bacteremia, rose spots and stepladder fever--chronic carriage can last entire lifetime |
| Urinary tract infection (UTI) | caused by E. coli-- |
| Zoonosis | disease transmission from animal to human |
