Abstract:
Objective To develop a PFGE protocol for Streptococcus suis.Methods We developed and optimized a PFGE protocol for S.suis,in terms of plug preparation,choice of restriction endonucleases and optimized electrophoresis parameters.By analyzing the genome sequences of S.suis P1/7 with Mapdraw of DNAStar.we found three restriction enzymes,Swa Ⅰ,Sma Ⅰ and Apa Ⅰ,were more suitable than others.Results Analysis of 100 isolates of S.suis including 34 of 35 serotypes identified,59,53 and 43 patterns were obtained from Swa Ⅰ,Sma Ⅰ and Apa Ⅰ restriction,respectively.The enzyme Swa Ⅰ had the greatest power for discrimination ability.Conclusion By optimization of the protocol at various conditions,a rapid,reproducible,economic and practical PFGE method for S.suis was developed.
