摘要：猪链球菌病是传染病，研究发现致病性链球菌是猪链球菌病的病原。一旦患上猪链球菌病的生猪会呈现出多种症状，包括败血症、关节炎、脑膜炎和淋巴结脓肿。猪链球菌病传播速度非常快且病程较短，导致生猪死亡率极高。猪链球菌病会导致生猪病亡影响生猪养殖业发展。该文主要论述猪链球菌病的病原学，对猪链球菌病的发病特点、临床症状及诊治方法等进行分析，提出猪链球菌病的综合防治措施，为生猪养殖业的发展提供参考。

Abstract：Streptococcus suis is a zoonotic infectious disease. It was found that the pathogenic streptococcus suis is the pathogen of Streptococcus Suis. Pigs infected with Streptococcus Suis can present with a variety of symptoms，including sepsis，arthritis，meningitis and lymph node abscesses. Streptococcus suis disease spreads very fast and has a short course，resulting in a high mortality rate of live pigs. Pig streptococcosis not only causes the death of live pigs，but also affects the development of pig breeding industry. This paper mainly discusses the aetiology of Swine Streptococcosis，analyses the pathogenic characteristics，clinical symptoms，diagnosis and treatment of Streptococcus Suis，and finally puts forward the comprehensive prevention and treatment measures of Streptococcus Suis disease，this paper provides some suggestions for the development of pig breeding industry.

Keywords：swine streptococcosis，etiology，clinical symptoms，treatment

0引言

猪链球菌病是由多种致病性猪链球菌感染后引起的传染病。在我国多个地区都有感染和发病的相关报道，给养殖场造成巨大的经济损失。现有的研究显示，猪链球菌病的病原是传染性极强的致病性链球菌，且有5种菌型，分别是猪链球菌2型、猪链球菌9型、C群马链球菌兽疫亚种、D群链球菌及E群链球菌。猪链球菌的血清类型有20种，一般是圆形或椭圆形的形态，链式排列长短不一，是革兰氏阳性球菌的一种。对猪链球菌在血液琼脂培养基内进行体外培养观察24 h时可看到菌落水滴形的形状，且呈现透明灰白色。空气灰塵、土壤和水及动物的排泄分泌物都广泛存在链球菌，但链球菌容易消杀对环境的抵抗力不强，只要温度达到60 ℃且维持30 mm就可消杀，因此链球菌在干燥湿热的环境中难以存活，可针对猪链球菌的这一特性进行防治。……
