| 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 |
| dances with anthrax: wolves (canis lupus) kill anthrax bacteremic plains bison (bison bison bison) in southwestern montana. | bacillus anthracis, the cause of anthrax, was recovered from two plains bison (bison bison bison) cows killed by wolves (canis lupus) in montana, usa, without associated wolf mortality in july 2010. this bison herd experienced an epizootic in summer 2008, killing ∼ 8% of the herd, the first documented in the region in several decades. no wolf deaths were associated with the 2008 event. surveillance has continued since 2008, with research, ranch, and wildlife personnel diligent during summer. as ... | 2014 | 24484485 |
| genetic diversity among bacillus anthracis soil isolates at fine geographic scales. | environmental samples were collected from carcass sites during and after anthrax outbreaks in 2000 and 2001 in the bison (bison bison) population within wood buffalo national park and the hook lake region north of wood buffalo national park. bacillus anthracis spores were isolated from these samples and confirmed using phenotypic characterization and real-time pcr. confirmed b. anthracis isolates were typed using multiple-locus variable-number tandem repeat analysis (mlva15) and single-nucleotid ... | 2012 | 22773624 |
| 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 |
