Profuse rice water stool diarrhea causing rapid loss of fluid and electrolytes. Enterotoxin, ability to attach to microvilli of brush. Found in brackish estuarine (salt + fresh) water. Wound infections from infected water sources and skin injury. Positive oxidase test, inability to grow in salt. Negative: second most common cause of nosocomial pneumonia. In particular: ventilated-associated pneumonia: third most common cause of urinary tract infections, fifth most common isolate overall from all sites of infection. Exotoxin a (tissue necrosis); binding (pili/flagella); lps (septic shock); chronic colonizer; intrinsic and acquired antibiotic resistance. Distinct odor of musky grape or corn husk.
