Streptococcus is an important zoonosis bacteria that can cause pigs Septicaemia, meningitis, Pneumonia, multi-arthritis and multi-polyserositis. Once people being suffered from the type 2 Streptococcus, it will show serious clinical symptom and death with its toxin factor. The paper gives it particular summarizing from epidemiology, pathogeny and its factor, nosogenesis and its prevention. And the paper also expounds that nosogenesis and prevention of Streptococcus in Henan province by the three tests of those Isolation and Pathogeny Identification, bacterin study and drug sensitive.First of all, from those 308 pieces of suspicious sample in hose 30 Henan county or city, they were found 260 positive samples which involved 84.4% by the direct microscopical check and sample culture microscopical check. Though its isolation, those of 26 typical separating trunks were identified and shew that the cause of the disease of streptococcus in Henan focused on E group (7/20), C group (6/20), D group (3/20) and L group (3/20), and with its no obvious distribution figure.Those identified 4 trunks C,D,L,E mixture bacteria were made into aluminum hydroxide multivalence inactivate bacterin. The inactivate bacterin was conducted with immune test through quality test, safety test and effective test. Through 990 pigs'vaccination, it shew that although with...
