Abstract
Phage-encoded virulence genes of group A streptococci were detected in 10 (55.6%) of 18 isolates of group C streptococci that had caused bovine mastitis. Bovine isolates carried other genetic determinants, such as composite transposon Tn1207.3/F10394.4 (100%) and antimicrobial drug resistance genes erm(B)/erm(A) (22.2%), linB (16.6%), and tet(M)/tet(O) (66.7%), located on mobile elements.
摘要
18 株引起牛乳腺炎的 C 群链球菌分离株中，有 10 株（55.6%）检测到 A 群链球菌噬菌体编码的毒力基因。牛源分离株携带其他遗传决定簇，如复合转座子 Tn1207.3/F10394.4（100%）和抗菌药物耐药基因 erm(B)/erm(A)（22.2%）、linB（16.6%）和 tet(M)/tet(O)（66.7%），这些基因位于移动元件上。
