| a serologic survey of pronghorns in alberta and saskatchewan, 1970-1972. | to determine the exposure of free-ranging pronghorns (antilocapra americana ord) to selected pathogens, serum samples were obtained from 33 live-trapped animals from southwestern saskatchewan in 1970, and from 26 and 51 animals from southeastern alberta, in 1971 and 1972, respectively. antibodies were found to the agents of parainfluenza 3, bovine virus diarrhea, eastern and western encephalomyelitis, infectious bovine rhinotracheitis and the chlamydial group. no serologic reactors were found to ... | 1975 | 167203 |
| infection of cattle with brucella abortus biovar 1 isolated from a bison in wood buffalo national park. | an experiment was conducted to determine if cattle could be infected with a strain of brucella abortus biovar 1 isolated from a bison in wood buffalo national park. three pregnant cows inoculated conjunctivally with 5.7 x 10(8) cfu of the bacterium, and their subsequent calves, showed seroconversion on standard serological tests for bovine brucellosis, and large numbers of the bacterium were isolated from numerous tissues at necropsy. a 4th cow that was moved into the pen that previously contain ... | 1996 | 8809394 |
| experimental brucella abortus infection in wolves. | four juvenile male wolves (canis lupus) each received an oral dose of 1.6-1.7 x 10(12) colony-forming units of brucella abortus biovar 1 isolated from a bison (bison bison) in wood buffalo national park (canada), and two others served as negative controls. infected wolves did not show clinical signs of disease but did develop high brucella antibody titers. small numbers of b. abortus were excreted sporadically in feces until day 50 postinoculation (pi). very small numbers of the bacterium were i ... | 2004 | 15137489 |
