“…Boreal caribou in the Northwest Territories are exposed to either BHV-1 or another virus antigenically similar to BHV-1. Antibodies to BHV-1 also have been reported in woodland caribou (Rangifer tarandus caribou) in Quebec, Canada (Elazhary et al, 1981), and Alaska, USA (Dieterich, 1981). The identity of the herpesvirus(es) responsible for production of antibodies in these populations of caribou remains unknown.…”

ABSTRACT:Boreal caribou (Rangifer tarandus caribou) are an ecologically and culturally important wildlife species and now range almost exclusively in the boreal forests of Canada, including the Northwest Territories, northern Alberta, and British Columbia. Boreal caribou are threatened throughout their Canadian range because of direct and indirect natural and anthropogenic factors. In the Northwest Territories, however, they have a continuous range that overall has not yet been subjected to the same degree of anthropogenic habitat fragmentation and degradation that has occurred elsewhere in Canada. To monitor the health of boreal caribou populations and individuals, we collected blood from 104 adult, female boreal caribou captured between March 2003 and February 2006 and measured serum biochemical parameters. Serum creatinine was higher in pregnant than in nonpregnant caribou. Several biochemical parameters differed among years, but they tended to be similar to those reported for reindeer. Serum antibodies were found to an alphaherpesvirus, Toxoplasma gondii, and to the Mycobacterium avium subspecies paratuberculosis in 37.5, 2.9, and 1.3% of boreal caribou, respectively. Fecal samples were collected from 149 boreal caribou, and Cryptosporidium sp. oocysts, Giardia sp. cysts, trichostrongyle ova, dorsal-spined nematode larvae, cestode ova, and Eimeria sp. were found. Trypanosoma sp. was detected in the blood of 72.1% of boreal caribou. Eimeria sp., Cryptosporidium sp., and Giardia sp. have not been previously reported in boreal caribou.

“…Pestiviruses have been detected in several cervids, including red deer (Nettleton et al, 1980), roe-deer (Frolich and Hofman, 1995), reindeer (Becher et al, 1999), caribou (Elazahary et al, 1981), and moose (Thorsen and Henderson, 1971). Surveys on bovine viral diarrhea virus (BVDV) antibodies have been conducted in various deer species.…”

372 sera of cervids from the Czech Republic were examined for antibodies to the bovine viral diarrhea virus (BVDV) and border disease virus (BDV) by competitive-inhibition enzyme-linked immunosorbent assay (ELISA), and for the presence of the BVDV by AgELISA. Antibodies to BVDV/BDV were found in 0.6% (two positive/305 tested) red deer (Cervus elaphus). BVDV/BDV antibodies were not found in four sika deer (Cervus nippon) and 63 fallow deer (Dama dama). All serum samples were BVDV antigen negative. Our results confirmed that red deer in the Czech Republic are only rarely infected with Pestiviruses. This was the first survey of pestiviruses in farmed and wild cervids in the Czech Republic.

“…18% of moose in Canada (Thorsen & Henderson, 1971) and 12% in Alaska ( Kocan et al, 1986) have been reported to be seropositive. In Canada, 69% of caribou tested in 1978 and 60% tested in 1979 had specific antibodies against BVDV (Elazhary et al, 1981), whereas Zarnke (1983) only found 3% seroprevalence in caribou in Alaska. In pronghorns, seropositive reactors were found in Canada (4%) (Barrett & Chalmers, 1975) and Idaho (Stauber et al, 1980).…”

“…Pastoret et al (1988) supposed that wild species do not play a major role in transmitting infection to domestic cattle. In free-ranging deer, the highest seroprevalence (60%-70%) was detected in Canadian caribou by Elazhary et al (1981) although these caribou had had no direct contact with domestic ruminants for 25 years. Frölich (1995) found no significant difference in antibody prevalence among deer in habitats with high, intermediate and low densities of cattle.…”

This paper describes viral diseases reported in northern ungulates and those that are a potential threat to these species. The following diseases are discussed: bovine viral diarrhoea/mucosal disease (BVD/MD), alphaherpesvirus infections, malignant catarrhal fever (MCF), poxvirus infections, parainfluenza type 3 virus infection, Alvsborg disease, foot-and-mouth disease, epizootic haemorrhage disease of deer and bluetongue disease, rabies, respiratory syncytial virus infection, adenovirus infection, hog-cholera, Aujeszky's disease and equine herpesvirus infections. There are no significant differences in antibody prevalence to BVDV among deer in habitats with high, intermediate and low density of cattle. In addition, sequence analysis from the BVDV isolated from roe deer (Capreolus capreolus) showed that this strain was unique within BVDV group I. Disrinct BVDV strains might circulate in free-ranging roe deer populations in Germany and virus transmission may be independent of domestic livestock. Similar results have been obtained in a serological survey of alpha-herpesviruses in deer in Germany. Malignant catarrhal fever was studied in fallow deer (Cervus damd) in Germany: the seroprevalence and positive PCR results detected in sheep originating from the same area as the antibody-positive deer might indicate that sheep are the main reservoir animals. Contagious ecthyma (CE) is a common disease in domestic sheep and goats caused by the orf virus. CE has been diagnosed in Rocky Mountain bighorn sheep (Ovis canadensis), mountain goats (Oreamnos americanus), Dall sheep (Ovis dalli), chamois (Rupkapra rupicapra), muskox {Ovibos moschatus) and reindeer (Rangifer tarandus). Most parainfluenza type 3 virus infections
