Document Summary
Single polar flagellum which allows them to corkscrew their way through fluids faster than any other bacteria. Microaerophilic and capnophilic, will not grow in air. Wild birds form the principal reservoirs for farm animals. Consumption of raw or undercooked poultry, meat, fish and shellfish. Commonly in raw milk due to fecal contamination at milking and occasionally to campylobacter mastitis. Also transmitted through handling raw meat and cross-contamination of foods. Can be grown from most poultry in stores. Air chilling greatly reduces the number of bacteria. The most common cause of acute enteritis in developed countries. Two closely related species, c. jejuni and c. coli, >100 serotypes. Acute enterocolitis has histological features indistinguishable from salmonella or shigella. Most strains produce a cholera-like e(cid:374)teroto(cid:454)i(cid:374) a(cid:374)d o(cid:374)e or (cid:373)ore (cid:272)(cid:455)toto(cid:454)i(cid:374)s e(cid:454)plosi(cid:448)e diarrhea. Incubation period 1 to 7 days occasionally with a febrile prodrome. Most recover within a week but reactive arthritis develops in about 1% one to two weeks after onset.
