| immunization of black-tailed prairie dog against plague through consumption of vaccine-laden baits. | prairie dogs (cynomys spp.) are highly susceptible to yersinia pestis and, along with other wild rodents, are significant reservoirs of plague for other wildlife and humans in the western united states. a recombinant raccoon poxvirus, expressing the f1 antigen of y. pestis, was incorporated into a palatable bait and offered to three groups (n = 18, 19, and 20) of black-tailed prairie dogs (cynomys ludovicianus) for voluntary consumption, either one, two, or three times, at roughly 3-wk intervals ... | 2008 | 18957649 |
| 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 |
| a survey of the prevalence of selected bacteria in wild birds. | we determined the prevalence of six genera of bacteria from a sample of 387 cloacal swabs from 364 passerines and woodpeckers. the prevalence of bacteria were as follows: escherichia coli (1%), pseudomonas spp. (22%), salmonella spp. (0%), staphylococcus spp. (15%), streptococcus spp. (18%), and yersinia spp. (1%). the prevalence of streptococcus spp. was higher in omnivorous species than in granivorous species (20% versus 8%). individuals captured at feeders had a lower prevalence of both strep ... | 1988 | 3286907 |
| 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 |
