Abstract：In recent years，with the rise of animal husbandry industry，pig farming is also on the rise，and coupled with the continuous improvement of people's quality of life，pork has become an essential meat product for residents. The quality of pork will directly affect people's health，and more efforts should be made to prevent the occurrence of diseases in pigs during the rearing process. Among the many infectious diseases affecting the health of pigs，streptococcal disease is particularly important，which not only infects pigs，but also further infects humans. In this paper，the prevalence and symptoms of streptococcal disease in pigs are analyzed，and a series of prevention and control measures are developed to safeguard human life and further ensure the economic benefits of farms while safeguarding the health of pigs.

0引言

豬的传染病种类较多，猪链球菌病的病原体，常年潜伏在猪身上，一旦受到外界因素的刺激，很有可能发生变异，养殖者应掌握该病的具体情况，并提前做好预防工作[1]。预防该病时，要制定科学、合理的措施，如发现患病猪时，应立即隔离，并采取有效的治疗方案，在阻断其传播途径的同时，控制病情的蔓延。

1流行病学

猪链球菌病是由链球菌引起的，各年龄段猪都可感染，其中体重30～50 kg的猪最易发。该病没有明显的季节性，但在春、秋季节容易高发，病原菌可以通过猪的消化道、损伤的皮肤等进行传播，未处理的患病猪及被污染过的饲料、水等，均可携带病原菌。此外，气候环境的变化，猪的生长状况，猪舍的卫生条件等，都可成为本病的发生诱因。该病还有一定的潜伏期，潜伏时间也受到其他因素的影响，短的可在数小时内发病，长的可达1周以上。

2传播途径

猪链球菌主要通过携带病原菌的病猪传播，如果母猪携带该病原菌，在其分娩过程中可传播给仔猪[2]。猪链球菌可在猪的呼吸道寄生，由于该病原菌具有很强的耐酸性，饲料和饮水中都会存在。……
