| 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 |
| pathogenesis and epidemiology of brucellosis in yellowstone bison: serologic and culture results from adult females and their progeny. | our objective in this prospective study was to determine the natural course of brucella abortus infection in cohorts of seropositive and seronegative, female bison (bison bison) and their offspring in yellowstone national park (ynp) for 5 yr. we collected specimens from 53 adult females and 25 calves at least once and from 45 adults and 22 calves more than once. annual seroconversion rates (negative to positive) were relatively high (23% for calves and juvenile bison, 6% in the total sample of a ... | 2009 | 19617483 |
