Abstract
According to the cultural and staining characteristics,morphology and biochemical test,slide agglutination test and PCR typing of Streptococcus suis,a strain of Streptococcus suis type 2 was isolated from samples of sick and dead pig.Animal pathogenicity test demonstrated that 2×108 doses could be lethal to mice,muramidase released protein(MRP),extracellular factor(EF) and hemolysin(sly) were all positive according to PCR detection,it provided a candidate strain for oneself inactivated vaccine preparation.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
