Wildlife

 


Many cases of Brucella infections among wildlife species have been reported such as bison, elk, and chamois. As cited previously, there are reports of an abortion in a dolphin and positive serologic tests in several other marine animals some marine mammals (Ewalt et al., 1994) due to a yet unclassified organism.

Brucellosis has also been reported in the one-humped camel (Camelus dromedarius) and the two-humped camel (C. bactrianus), related to contact with large and small ruminants infected with B. abortus or B. melitensis. In addition, brucellosis has been observed in the domestic buffalo (Bubalus bubalus), Bison (Bison bison), yak (Bos grunniens), elk (Cerves canadensis) and also occurs in the African buffalo (Syncerus caffer) and various African antelope species. The manifestations of brucellosis in these animals are similar to those in cattle.

Although many species of wildlife may be infected with Brucella spp, it appears that they are of little importance as reservoirs of infection for domestic animals. An exception is the European hare which may be a source of B. suis biovar2 for swine.
