摘 要
猪链球菌病是由猪链球菌引起的一种人畜共患疾病，严重威胁着养猪业的发展和人类健康。本研究旨在深入探讨猪链球菌病的临床特征与防治技术，为该病的有效防控提供科学依据。通过对国内外相关文献的系统梳理以及对发病猪场的实地调查，结合实验室诊断技术，包括细菌分离鉴定、药敏试验等方法，全面分析了猪链球菌病的流行特点、临床症状及病理变化。研究发现，猪链球菌病主要表现为败血症、脑膜炎、关节炎等多种类型，不同日龄猪只均可感染且发病率和死亡率较高；在防治方面，筛选出对猪链球菌敏感的药物，并提出综合防控措施，如加强饲养管理、严格执行生物安全制度等。

ABSTRACT
Streptococcus suis is a zoonotic disease caused by streptococcus suis, and it is a serious threat to the development of pig industry and human health. This study aims to explore the clinical characteristics and prevention techniques of streptococcus swine disease and provide a scientific basis for the effective prevention and control of the disease. Through the systematic combing of the relevant literature at home and abroad, the field investigation of the diseased pig farm, combined with the laboratory diagnostic technology, including bacterial isolation and identification, drug susceptibility test and other methods, the epidemic characteristics, clinical symptoms and pathological changes of swine streptococcus disease were comprehensively analyzed. The study found that swine streptococcus disease is mainly manifested by septicemia, meningitis, arthritis and other types, and pigs of different ages can be infected and have high morbidity and mortality. In terms of prevention and treatment, select drugs sensitive to Streptococcus suis, and propose comprehensive prevention and control measures, such as strengthening feeding management and strict implementation of biosafety system.
