yersinia enterocolitica of porcine origin: carriage of virulence genes and genotypic diversity.	yersinia enterocolitica is an important foodborne pathogen, and pigs are recognized as a major reservoir and potential source of pathogenic strains to humans. a total of 172 y. enterocolitica recovered from conventional and antimicrobial-free pig production systems from different geographic regions (north carolina, ohio, michigan, wisconsin, and iowa) were investigated to determine their pathogenic significance to humans. phenotypic and genotypic diversity of the isolates was assessed using anti ...	2013	23320426
the wisconsin state laboratory of hygiene and emerging enteric pathogens.	at the turn of the 20th century, typhoid fever was common in wisconsin, and was a major impetus for the establishment of the wisconsin state laboratory of hygiene (wslh) in 1903. by the 1940s, typhoid was virtually eliminated in the united states due to public health measures such as disinfection of drinking water, sewage treatment, pasteurization, and shellfish bed sanitation. however, new food and waterborne pathogens have emerged to take the place of salmonella typhi. infections with non-typh ...	2003	14658567
prevalence of yersinia enterocolitica in waters of the lower chippewa river basin, wisconsin.	water samples collected over a 14-month period from the lower chippewa river drainage basin in wisconsin were examined for yersinia enterocolitica with either macconkey-tween 80 agar or y-m agar (t. n. saari and g. p. jansen, contrib. microbiol. immunol. 5:185-196) as the selective medium. a new method of isolation was developed. of 303 water samples, 8.25% were positive. a seasonal variation was noticed, with winter isolations being most frequent.	1982	7081989
human yersinia enterocolitica infections in wisconsin. clinical, laboratory and epidemiologic features.	yersinia enterocolitica has been sought in stool and blood culture specimens by the wisconsin state laboratory of hygiene (slh) since 1973. clinical information on symptoms, duration of illness, and use of antibiotics for 41 persons with y. enterocolitica infections from january 1, 1979, to september 30, 1980, was obtained by telephone interviews. diarrhea and abdominal pain were the most common symptoms of the ill persons; extraintestinal symptoms were infrequently reported. ten infected person ...	1982	7081274
waterborne yersinia enterocolitica in the midwest united states.	one hundred forty strains of waterborne y. enterocolitica were isolated from wisconsin and colorado rivers, lakes and wells between october 1974 and march 1976- direct-plating of unconcentrated water specimens on deoxycholate-citrate-mannitol (y-m) agar resulted in 89 isolates. prolonged incubation of specimens in cooked meat broth produced 51 additional strains. most organisms were indole-positive, niléln biotype 1 with 24% belonging to the rhamnophilum subgroup. twenty-three serotypes were rep ...	1979	535377
