凉州区绵羊传染性胸膜肺炎血清学调查

Serological Investigation of Infectious Pleural Pneumonia in Liangzhou District

摘要:

为了解和掌握凉州区绵羊传染性胸膜肺炎感染和流行情况,我们于2023年3月在全区范围内选取14个规模养羊场采集390份血样开展了绵羊传染性胸膜肺炎血清学调查。经检测,非免疫养殖场羊群绵羊支原体感染抗体平均阳性率为6.1%;免疫养殖场羊群绵羊支原体免疫抗体平均阳性率为75.3%;疑似发病养殖场羊群支原体感染抗体平均阳性率为78.3%。结果证明,凉州区规模养殖场存在绵羊肺炎支原体感染的情况,应引起重视。本实验可为凉州区规模养殖场科学制定绵羊传染性胸膜肺炎预防和治疗技术方案,针对性采取切实有效防控措施等方面提供参考。

Abstract:

In order to understand and master the infection and epidemic situation of infectious pleural pneumonia in sheep in Liangzhou District,we collected 390 sheep samples from 14 largescale sheep farms in March 2023 to carry out the serological investigation of infectious pleural pneumonia in sheep.After testing,the average positive rate of antibodies against mycoplasma infection was 6.1% in nonimmune sheep;the average positive rate of mycoplasma antibody was 75.3%;the average positive rate of antibodies against mycoplasma ovipneumoniae infection in the sheep flocks of suspected diseased farms was 78.3%.The results proved that there was mycoplasma ovipneumoniae infection in largescale farms in Liangzhou District,which should be paid attention to.This experiment provides reference for the largescale farms in Liangzhou District to develop the prevention and treatment technology of infectious pleural pneumonia in sheep,and take targeted and effective prevention and control measures.
