| survey of free-ranging elk from wyoming and montana for selected pathogens. | from december 1991 through january 1995, a disease survey was conducted on herds of free-ranging, hunter-killed elk (cervus elaphus nelsoni) from three areas in proximity to yellowstone national park (ynp), wyoming (usa), after tuberculosis caused by mycobacterium bovis was discovered in a captive herd of elk in the area. complete or partial sets of specimens from 289 elk collected between december 1991 and january 1993 were examined histologically; no mycobacterial lesions were observed. lesion ... | 1997 | 9131561 |
| brucellosis in elk of eastern idaho. | brucellosis occurs in free-ranging elk (cervus elaphus) and bison (bison bison) in the greater yellowstone area, which includes portions of idaho, wyoming, and montana. brucella abortus was first detected in elk in idaho in 1998, and from 1998 to 2002, serologic surveillance of hunter-killed elk was conducted in northeastern and southeastern idaho. prevalence of antibodies in these elk varied annually, but averaged between 2% and 3%. elk were also trapped in northeastern idaho from 1998-2002 and ... | 2006 | 16870849 |
| probable causes of increasing brucellosis in free-ranging elk of the greater yellowstone ecosystem. | while many wildlife species are threatened, some populations have recovered from previous overexploitation, and data linking these population increases with disease dynamics are limited. we present data suggesting that free-ranging elk (cervus elaphus) are a maintenance host for brucella abortus in new areas of the greater yellowstone ecosystem (gye). brucellosis seroprevalence in free-ranging elk increased from 0-7% in 1991-1992 to 8-20% in 2006-2007 in four of six herd units around the gye. th ... | 2010 | 20349847 |
