Strain-dependent interactions of Streptococcus suis and Glaesserella parasuis in co-culture.

ABSTRACT: Streptococcus suis (S. suis) and Glaesserella parasuis (G. parasuis) are ubiquitous colonizers of swine tonsils that can cause systemic disease and death, under undefined conditions. It is not known, however, whether these 2 species interact during initial infection. To investigate whether such interactions occur, the objective of this study was to assess phenotypic differences between mono-and co-cultures of S. suis and G. parasuis when representative strains with different virulence potential were co-cultured in vitro. In cross-streak screening experiments, some G. parasuis (GP) serovar strains (GP3, GP4, GP5) exhibited altered morphology with some S. suis (SS) serovar strains, such as SS2, but not with SS1. Co-culture with GP5 reduced hem
