Streptococcus suis Serotype 2 Capsule In Vivo
Many Streptococcus suis isolates from porcine endocarditis in slaughterhouses have lost their capsule and are considered avirulent. However, we retrieved capsule- and virulence-recovered S. suis after in vivo passages of a nonencapsulated strain in mice, suggesting that nonencapsulated S. suis are still potentially hazardous for persons in the swine industry.
متن کاملIdentification of an inducible bacteriophage in a virulent strain of Streptococcus suis serotype 2.
Streptococcus suis infection is considered to be a major problem in the swine industry worldwide. Most virulent Canadian isolates of S. suis serotype 2 do not produce the known virulence markers for this pathogen. PCR-based subtraction hybridization was adapted to isolate unique DNA sequences which were specific to virulent strains of S. suis isolated in Canada. Analysis of some subtracted DNA ...
متن کاملComplete Genome Sequence of Streptococcus suis Serotype 2 Virulent Strain SS2-1
Streptococcus suis is an important swine pathogen that can also cause severe diseases in humans. Herein, we describe the genome sequence of Streptococcus suis serotype 2 virulent strain SS2-1, which was isolated from a diseased dead pig amid the 1998 Streptococcus suis outbreak in Jiangsu Province in China.
متن کاملAntibody response specific to the capsular polysaccharide is impaired in Streptococcus suis serotype 2-infected animals.
Streptococcus suis serotype 2 is an extracellular encapsulated bacterium that causes severe septicemia and meningitis in swine and humans. Albeit crucial in the fight against encapsulated bacteria, the nature of the capsular polysaccharide (CPS)-specific antibody (Ab) response during S. suis type 2 infection is unknown. We compared for the first time the features of CPS-specific versus protein-...
متن کاملProtection against Streptococcus suis Serotype 2 Infection Using a Capsular Polysaccharide Glycoconjugate Vaccine.
Streptococcus suis serotype 2 is an encapsulated bacterium and one of the most important bacterial pathogens in the porcine industry. Despite decades of research for an efficient vaccine, none is currently available. Based on the success achieved with other encapsulated pathogens, a glycoconjugate vaccine strategy was selected to elicit opsonizing anti-capsular polysaccharide (anti-CPS) IgG ant...
