Spread of Streptococcus suis sequence type 7, China

Emerg Infect Dis. 2008 May;14(5):787-91. doi: 10.3201/eid1405.070437.

Abstract

Streptococcus suis sequence type (ST) 7 has been spreading throughout China. To determine events associated with its emergence, we tested 114 isolates. In all 106 ST7 strains responsible for human outbreaks and sporadic infections, the tetracycline-resistance gene, tetM, was detected on the conjugative transposon Tn916. Horizontal transmission of tetM is suspected.
