“…Abortions or retained placentas in bison from brucellosis infected herds have been reported (Creech, 1930;Corner and Connell, 1958), and have been observed in experimental infections (Davis et al, 1990(Davis et al, , 1991; however, only two naturally-occurring abortions with laboratory confirmation of B. abortus as the causative agent have been reported (Williams et al, 1993;Rhyan et al, 1994). Little additional information is published on the pathogenesis of B. abortus infection in female bison, and some investigators have speculated that the disease in YNP bison is markedly different from that in cattle (Meyer and Meagher, 1995). The objectives of this study were to determine the sites of tissue colonization of B. abortus in aborted bison fetuses and in juvenile and adult female bison from YNP, to determine the uterine and fetal pathology associated with brucellosis in YNP bison, and to compare the results with those from cattle.…”

Between February 1995 and June 1999, specimens from seven aborted bison (Bison bison) fetuses or stillborn calves and their placentas, two additional placentas, three dead neonates, one 2-wk-old calf, and 35 juvenile and adult female bison from Yellowstone National Park (USA) were submitted for bacteriologic and histopathologic examination. One adult animal with a retained placenta had recently aborted. Serum samples from the 35 juvenile and adult bison were tested for Brucella spp. antibodies. Twenty-six bison, including the cow with the retained placenta, were seropositive, one was suspect, and eight were seronegative. Brucella abortus biovar 1 was isolated from three aborted fetuses and associated placentas, an additional placenta, the 2-wk-old calf, and 11 of the seropositive female bison including the animal that had recently aborted. Brucella abortus biovar 2 was isolated from one additional seropositive adult female bison. Brucella abortus was recovered from numerous tissue sites from the aborted fetuses, placentas and 2-wk-old calf. In the juvenile and adult bison, the organism was more frequently isolated from supramammary (83%), retropharyngeal (67%), and iliac (58%) lymph nodes than from other tissues cultured. Cultures from the seronegative and suspect bison were negative for B. abortus. Lesions in the B. abortus-infected, aborted placentas and fetuses consisted of necropurulent placentitis and mild bronchointerstitial pneumonia. The infected 2-wk-old calf had bronchointerstitial pneumonia, focal splenic infarction, and purulent nephritis. The recently-aborting bison cow had purulent endometritis and necropurulent placentitis. Immunohistochemical staining of tissues from the culture-positive aborted fetuses, placentas, 2-wk-old calf, and recently-aborting cow disclosed large numbers of B. abortus in placental trophoblasts and exudate, and fetal and calf lung. A similar study with the same tissue collection and culture protocol was done using six seropositive cattle from a B. abortus-infected herd in July and August, 1997. Results of the bison and cattle studies were similar.

“…The role of elk and bison in the acquisition of B. abortus by cattle in the regions of Idaho, Wyoming, and Montana comprising the Greater Yellowstone Area (GYA) is a politically charged feature of wildlife management and land use programs in that territory (7,18). Seroprevalence rates among elk herds in the GYA range from 8 to 60%, while in bison herds, seroprevalence ranges from 11 to 75% (8,9,12,21,22,23).…”

ABSTRACTA variable-number tandem repeat (VNTR) protocol targeting 10 loci in theBrucella abortusgenome 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 from Texas segregated into three clusters: one comprised of field isolates from 1998 to 2005, one comprised of vaccination-associated infections, and one associated with an outbreak in Starr County in January 2011. An isolate obtained from a feral sow trapped on property adjacent to the Starr County herd in May 2011 clustered with the cattle isolates, suggesting a role for feral swine asB. abortusreservoirs in Starr County. Isolates from a 2005 cattle outbreak in Wyoming displayed VNTR-10 profiles matching those of strains recovered from Wyoming and Idaho elk. Additionally, isolates associated with cattle outbreaks in Idaho in 2002, Montana in 2008 and 2011, and Wyoming in 2010 primarily clustered with isolates recovered from GYA elk. This study indicates that elk play a predominant role in the transmission ofB. abortusto cattle located in the GYA.

“…There is a theoretical potential for domestic bovine brucellosis to infect wildlife such as moose or bison [19], but no bovine brucellosis has been documented in this province recently. Brucellosis among some free ranging wood bison in the east neighboring Alberta province is known [20].…”

The Canadian province of British Columbia has a luxurious environment, complete with the multitude of wildlife and insects, and would at first glance appear to be suitable for the transmission of diseases in nature communicable to humans. Despite this potential, such diseases are relatively uncommon, although several have the potential for serious consequences. Attention has been recently focused on hantavirus infection, water-borne toxoplasmosis and parasitic diarrheal diseases, cryptococcosis on Vancouver Island, and rabies. West Nile virus has not yet caused endemic human infection in this province as of 2008. We review the cumulative science in this area.
