摘要
To fully understand swine stroptococcosis in Binzhou and surrounding areas, we studied its incidence rate and incidence characteristics in 2013, in order to put forward constructive suggestions for scientific prevention and control of swine streptococcosis. Isolation and purification, biochemical and molecular biolo- gy identification and drug susceptibility test of Streptococcus suis were carried out, and mixed infection of S. suis with classical swine fever virus, pseudorabics virus and porcine circovirus virus was statistically analyzed. The results showed that 46 strains of S. suis were screened, and the positive rate was approximately 24.9%, with high degree of resistance and multiple resistances. S. suis had different degrees of mixed infection with classical swine fever virus, pseudorabics virus and porcine cireovirus virus, and the total mixed infection rate was 58.7%.
