Abstract
Group B Streptococcus sequence type 103 is known primarily as a bovine mastitis pathogen. In Brazil, it has circulated in cattle and humans since the 1990s. It lacks scpB and, in humans, was found only among carriage isolates. Bovine-human interspecies transmission may have contributed to its evolution and spread.
摘要
B 群链球菌 103 型主要是一种牛乳腺炎病原体。自 20 世纪 90 年代以来，它就在巴西的牛群和人群中传播。它缺乏 scpB 基因，而且仅在人类的带菌者分离株中发现。牛与人之间的种间传播可能促成了其进化和传播。
