Identification and Detection of Serotype-Specific Genes: Effective Serotyping of Streptococcus suis

Purpose of review Streptococcus suis is an emerging zoonotic pathogen that can cause severe infections in pigs and humans. S. suis has been reported in Europe, America, and Asia, and has resulted in heavy losses to swine production and serious public health concerns. Serum agglutination has identified several serotypes. Here, we review the methods for serotyping S. suis, the current serological classifications, and the future trend in serotyping.
