title: Serotypes and putative virulence markers of Streptococcus suis isolates from cats and dogs.
abstract: Thirteen isolates of Streptococcus suis from cats and dogs were characterised. Formamide extracts of 10 of the 13 cultures reacted with group D specific antiserum, and serotyping of the cultures with specific antisera against capsular types 1 to 28 revealed the serotypes 9, 20, 1/2, 22, 26 and 4; the remaining cultures were untypable. In addition one of the cultures reacted with monoclonal antibodies against muramidase-released protein and in parallel with monoclonal antibodies against the extracellular factor (EF) of S suis. The latter reacted with proteins with a molecular weight of more than 150,000 indicating that the strain exhibited EF-related proteins. One of the 13 cultures haemagglutinated erythrocytes from human beings and various animal species and adhered in large numbers to HeLa cells.
