ABSTRACT
The characterization of 61 Streptococcus suis strains isolated from Chinese slaughter pigs was investigated. S. suis serotypes 1, 2, 3, 4, 7, 9, 10, 11, 12, 13, 14, 15, 16, 22, 23, 25, 26, 28, 29, and 1/2 were found in the isolates by serum agglutination. Of all the prevalent serotypes, S. suis serotype 7 is the most predominant circulating in Chinese slaughter pigs. The virulence-associated genes profile and multilocus sequence typing scheme of the isolates were analyzed. The mrp-/epf-/sly- virulence-associated genes type is the most prevalent in the isolates from slaughter pigs. It is the first time to find S. suis serotypes 7 and 9 isolates with epf. The serotypes 7 and 9 isolates with mrp and/or epf genes did not express MRP and/or EF in the present research. Thirteen new ST types were identified for the first time. ST1 complex and ST27 complex of S. suis are prevalent in China. This paper supplied information to understand the characteristics, such as capsular serotypes, virulence factors, and gene backgrounds of S. suis carried by slaughter pigs.
