the brucellosis and tuberculosis status of wood bison in the mackenzie bison sanctuary, northwest territories, canada. | postmortem examinations were done on 51 wood bison (bison bison athabascae) killed as part of a multidisciplinary research project in the mackenzie bison sanctuary, northwest territories, canada, between 1986 and 1988. there was no gross, histological or bacteriological evidence of brucellosis or tuberculosis in these bison. traumatic lesions were seen in one calf that had been attacked by wolves and a second calf that had been gored. antibody titers to brucella abortus were not found in sera fr ... | 1993 | 8269360 |
genetic variation within and relatedness among wood and plains bison populations. | there are two recognized subspecies of bison, wood (bison bison athabascae) and plains (bison bison bison) bison. the establishment of most bison populations from a small number of individuals has raised concerns about their genetic variation. to this end, 11 bison populations were surveyed with 11 microsatellite loci in order to calculate genetic variation and genetic distances. mean number of alleles ranged between 3.18 at antelope island state park (utah) and 6.55 at wood buffalo national par ... | 1999 | 10382295 |
capture of wood bison (bison bison athabascae) using carfentanil-based mixtures. | between 1986 and 1991, 155 wood bison (bison bison athabascae) (33 adult females, 92 adult males, twelve 6 mo-old calves, eighteen 1 to 2 mo-old calves) in the mackenzie bison sanctuary, northwest territories, canada, and adjacent area were captured by dart immobilization. initial trials with carfentanil, xylazine and r51163 as immobilizing agents were conducted. subsequently, carfentanil alone, or in combination with xylazine, was used. small doses of xylazine were used when required to control ... | 1995 | 7563422 |
parasites and diseases of bison in canada iv. serologic survey for brucellosis in bison in northern canada. | serum samples collected from 2,365 free-roaming hybrid bison (bison bison bison x bison bison athabascae) in wood buffalo national park and adjacent areas in the northwest territories were tested for brucellosis during the period 1959 to 1974. a positive reaction was obtained in 739 (31.2%) of the animals tested. the overall effect of brucellosis on this free-roaming bison population is unknown. the authors also dealt with some of the actual and possible consequences of the disease in this popul ... | 1978 | 691126 |
descriptive epidemiology of detected anthrax outbreaks in wild wood bison (bison bison athabascae) in northern canada, 1962-2008. | we inventoried and assessed historical anthrax outbreak data from 1962-2008 in wild wood bison (bison bison athabascae) in wood buffalo national park and the slave river lowlands (srl), northwest territories, canada. we compared these results with a 2010 outbreak in the srl. anthrax outbreaks have occurred in 12 of the years between 1962 and 2008 in wild wood bison with 1,515 anthrax deaths detected. the average number of carcasses found each outbreak year was 126 (range 1-363), though local ave ... | 2014 | 24779457 |
anthrax in the mackenzie wood bison (bison bison athabascae) population: 2012 anthrax outbreak and historical exposure in nonoutbreak years. | anthrax, caused by the spore-forming bacterium bacillus anthracis, poses a threat to wood bison (bison bison athabascae) conservation. we used descriptive epidemiology to characterize a large outbreak of anthrax in the mackenzie bison population in the northwest territories, canada, in 2012 and investigated historical serologic exposure of the bison to the bacterium in nonoutbreak years. between late june and early august 2012, 451 bison carcasses were detected; mortality peaked from 13-19 july. ... | 2017 | 28767322 |
