A total of 41 Brucella isolates, examined by standard biotyping procedures, were found to be similar to Brucella abortus biovar 2 in dye sensitivity but had a dominant M antigen. Oxidative metabolic tests performed on 39 of the isolates confirmed them as B. abortus. Additional biochemical and bacteriophage susceptibility studies were performed on 35 of the isolates. The isolates had identical reactions in the various tests, except for one isolate which was resistant to lysis by all phage strains used. Two isolates were injected into guinea pigs and shown to be virulent. The isolates described in this study appear similar to atypical Brucella isolates previously reported in the United Kingdom and the United States and may form the basis of a new biovar, B. abortus biovar 10.
通过标准生物分型程序检测的总共41株布鲁氏菌分离株，在染料敏感性方面与流产布鲁氏菌生物变种2相似，但具有占主导地位的M抗原。对其中39株分离株进行的氧化代谢试验证实它们为流产布鲁氏菌。对35株分离株进行了额外的生化和噬菌体敏感性研究。除了一株对所有使用的噬菌体菌株的裂解具有抗性的分离株外，其他分离株在各种试验中具有相同的反应。将两株分离株注射到豚鼠体内，结果显示具有致病性。本研究中描述的分离株似乎与先前在英国和美国报道的非典型布鲁氏菌分离株相似，可能构成一个新的生物变种——流产布鲁氏菌生物变种10的基础。
