| host defense function in neutrophils from the american bison (bison bison). | selected host defense functions of neutrophils isolated from american bison (bison bison) were characterized and compared with those of cattle (bos taurus). bison neutrophils had a robust chemotactic response to both il-8 and ltb(4), with maximal responses occurring at 10(-7) m (il-8) and 10(-8) m (ltb(4)). the magnitude of the chemotactic response to il-8 was similar in bison and bovine neutrophils (except at 10(-7) m il-8, where bison had a stronger response). in response to ltb(4), bison neut ... | 2000 | 11064290 |
| relationships among ecology, demography and diseases of european bison (bison bonasus). | the bison population in the bialowieza forest in poland has now grown to approximately 300, while the herds in the belarusian part of the forest total about 240 bison. the first signs of a health problem in these herds appeared in 1980, when two cases of balanoposthitis were detected in two bulls (2 and 5 years of age). since 1980 research has been conducted to explain the cause of diseases, particularly balanoposthitis, and to monitor the health of bison in bialowieza forest. a total number of ... | 2003 | 14703870 |
| prevalence of escherichia coli o157:h7 in the american bison (bison bison). | bison is becoming a popular meat source for consumers, but very little is known about the bison's status with respect to escherichia coli o157:h7. we conducted a study to determine the prevalence and identify virulence genes and pulsed-field genetic types of e. coli o157:h7 in bison. rectal contents and rectoanal mucosal swab (rams) samples were collected from a total of 342 bison at slaughter on seven different dates. isolation of e. coli o157:h7 was by enrichment, immunomagnetic separation, an ... | 2007 | 18044434 |
| a survey of the fecal bacteria of bison (bison bison) for potential pathogens and antimicrobial susceptibility of bison-origin e. coli. | an observational study determined the normal fecal bacterial flora of clinically healthy bison, detected the presence of common potential zoonotic pathogens, and determined the antimicrobial susceptibility of isolated e. coli strains. ninety-six fecal samples from 10 captive herds were cultured for aerobic, anaerobic, facultative, and microaerophillic bacteria. nineteen major genera of gram-positive and 8 genera of gram-negative bacteria were identified. salmonella spp. were not detected but som ... | 2011 | 21731097 |
