Eleven Brucella canis isolates from Canadian dogs were characterized by dye and antibiotic sensitivity, phage susceptibility, urease and H(2)S production, CO(2) requirement, and reaction with monospecific A,M, and R anti-Brucella antiserum. The isolates could be separated into two distinct groups. One group had a sensitivity pattern similar to that seen with the American type strain RM666, while the other group had a pattern identical to that of a Mexican strain, Mex 51. Epidemiological studies supported contraction of infections in the United States and Mexico respectively. The characteristics of all isolates were stable after repeated subculture indicating that strain differences could serve as useful epidemiological markers and supporting division of the species into two biovars.
对从加拿大犬类中分离出的11株犬布鲁氏菌进行了染料和抗生素敏感性、噬菌体敏感性、脲酶和硫化氢产生、二氧化碳需求以及与单特异性A、M和R抗布鲁氏菌抗血清反应的特性分析。这些分离株可分为两个不同的组。一组的敏感性模式与美国典型菌株RM666相似，而另一组的模式与墨西哥菌株Mex 51相同。流行病学研究分别支持在美国和墨西哥感染的传播。所有分离株在反复传代后特性稳定，表明菌株差异可作为有用的流行病学标志物，并支持将该物种分为两个生物变种。
