Background Streptococcus suis is a major porcine pathogen in many countries. It causes serious zoonotic diseases (diseases which can be transmitted naturally between animals and humans) such as meningitis, septicaemia, endocarditis, arthritis, and septic shock in both pigs and human beings, and mortality is high. There are 35 serotypes of S.suis, of which serotype SS2 is the most prevalent. Two recent large-scale outbreaks of streptococcal toxic shock syndrome (STSS) in China were caused by SS2 (in 1998 and 2005). Two highly virulent isolates from fatal cases of STSS, 98HAH33 from the 1998 outbreak and 05ZYH33 from the 2005 outbreak were sequenced and found to contain a novel 89 kb pathogenicity island not detected in other S.suis isolates. The pathogenicity island has probably been acquired by horizontal gene transfer. This might partially explain the virulence of these strains. (HAMAP: STRSY)
