Identification of a Strain of Streptococcus suis and the Main Virulence Factors Analysis
摘要
Abstract
[Objective] To identify a Streptococcus strain, so as to provide theoretical basis for further studying the toxicity of Streptococcus suis. [ Method ] The identification of the strain was performed by Gram stain and microscopy, and 16S rDNA gene sequence analysis. Seven main virulence genes were selected to design primers and the virulence gene distribution was detected by PCR. [Result] The strain was Gram positive bacterium, presenting chain - like distribution. The 16S rDNA sequence of the strain was above 99% of homology to Streptococcus suis 2. [Conclusion] The isolated strain was Streptococcus suis 2. The virulence genotype of this SS2 was: gdh+/ef+/mrp+/sly+/jbps+/orf2+/cps2J+/.关键词
