摘要
为了确定广东省某规模化猪场病死猪的发病原因,走访猪场的了解状况,解剖并采集发病猪只的心脏、肺脏等病变组织进行实验室检测鉴定,并对分离到的致病菌进行血清型鉴定和药敏试验分析。结果显示,该猪场感染了猪胸膜肺炎放线杆菌(Actinobacillus pleuropneumoniae,APP)7型和猪链球菌(Streptococcus suis,SS)2型。其中夏季高温高湿的环境应激是细菌病的主要诱发因素,并根据确诊结果和猪场整体环境情况提出相应的防治建议。
In order to determine the etiology of dead pigs in a large-scale pig farm,the general situation of the pig farm was investigated in Guangdong Province. The diseased tissues such as heart and lung of the diseased pigs were dissected and collected for laboratory detection and identification. The isolated pathogenic bacteria were identified for serotypes and analyzed for drug sensitivity test. The results showed that the pig farm was infected with Actinobacillus pleuropneumoniae(APP)type 7 and Streptococcus suis(SS)type 2. In summer,the bacterial disease was main caused by the environmental stress with high temperature and humidity,and the corresponding prevention and control suggestions were put forward according to the diagnosis results and the overall environment of the pig farm.
