嘉兴市规模猪场副猪嗜血杆菌感染规律研究

Study on Haemophilus parasuis Infection Regularity in Jiaxing Scale Pig Farms

[目的]研究嘉兴市规模猪场副猪嗜血杆菌病对保育猪的感染规律.[方法]对发病死亡的176头3～10周龄的保育猪,无菌采集关节液、心包液、心血、脑脊液等病料,应用细菌学、细菌生化反应及PCR技术,检测不同周龄保育猪副猪嗜血杆菌的感染情况.[结果]结果表明,在3～10周龄之间的保育猪均可检出副猪嗜血杆菌的感染,检出率高峰分布在5～8周龄之间,总检出率达到78.98％.[结论]该研究初步摸清了嘉兴市规模猪场保育猪副猪嗜血杆菌的感染规律,为在嘉兴市范围内预防和控制副猪嗜血杆菌病提供了理论依据.

[Objective]The aim was to study the Haemophilus parasuis infection rule in the scale pig farms in Jiaxing City. [Method]The joint fluid, pericardial fluid,blood and cerebrosPinal fluid, etc. from 176 dearnurSery pigs during the age from 3 to 10 weeks were collected, for detecting the infection status of Haemophilus parasuis by application of bacteriology, bacterial biochemical reac- tions and PCR technology. [Result]The results showed that all the weaners which between 3-10 weeks of age could be de- tected Haemophilus parasuis infections. The total detection rate was 78.98%, and the top detection rate distributed between 5-8 weeks. The study preliminary foud out the infections law of Haemophilus parasuis on weaners of scale farms in Ji- axing City, and provided a theoretical ba- sis for prevention and control of Haemophilus parasuis disease in Jiaxing range.
