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 ...200616870849
molecular epidemiology of brucella abortus isolates from cattle, elk, and bison in the united states, 1998 to 2011.a variable-number tandem repeat (vntr) protocol targeting 10 loci in the brucella abortus genome was used to assess genetic diversity among 366 field isolates recovered from cattle, bison, and elk in the greater yellowstone area (gya) and texas during 1998 to 2011. minimum spanning tree (mst) and unweighted-pair group method with arithmetic mean (upgma) analyses of vntr data identified 237 different vntr types, among which 14 prominent clusters of isolates could be identified. cattle isolates fr ...201222427502
brucellosis transmission between wildlife and livestock in the greater yellowstone ecosystem: inferences from dna genotyping.the wildlife of the greater yellowstone ecosystem carries brucellosis, which was first introduced to the area by cattle in the 19th century. brucellosis transmission between wildlife and livestock has been difficult to study due to challenges in culturing the causative agent, brucella abortus . we examined b. abortus transmission between american bison ( bison bison ), rocky mountain elk ( cervus elaphus nelsoni), and cattle ( bos taurus ) using variable number tandem repeat (vntr) markers on dn ...201728118557
an ecological perspective on brucella abortus in the western united states.after a hiatus during the 1990s, outbreaks of brucella abortus in cattle are occurring more frequently in some of the western states of the united states, namely, montana, wyoming and idaho. this increase is coincidentwith increasing brucellosis seroprevalence in elk (cervus elaphus), which is correlated with elk density. vaccines are a seductive solution, but their use in wildlife systems remains limited by logistical, financial, and scientific constraints. cattle vaccination is ongoing in the ...201323837367
a seroepidemiologic survey of three pronghorn (antilocapra americana) populations in southeastern idaho, 1975-1977.sera from 104 adult and 42 fawn pronghorn antelope (antilocapra americana) from southeastern idaho were tested against selected livestock pathogens. the numbers positive/numbers tested (% positive) were as follows: bovine virus diarrhea - adults 2/102 (2), fawns 0/41 (0);; infectious bovine rhinotracheitis - adults 27/101 (27), fawns 9/42 (22); parainfluenza 3 - adults 79/104 (76), fawns 22/42 (52); bovine adenovirus 7 - adults 42/103 (41), fawns 20/48 (48); bovine adenovirus 3 - adults 11/32 (3 ...19806246285
