摘要
【目的】旨在探究新疆哈密市伊州区某养殖户羊发病死亡的原因。【方法】采集病死羊的肺组织,进行分离培养、实时荧光定量PCR鉴定、普通PCR扩增以及基因测序分析。【结果】在改良的PPLO固体培养基上培养出了支原体;实时荧光定量PCR检测结果为支原体感染阳性;普通PCR扩增及基因测序,分离菌株与GenBank数据库中的精氨酸支原体同源性高达100%。【结论】研究结果表明,该养殖户羊发病死亡是由精氨酸支原体感染导致。
【Objective】In order to investigate the causes of illness and death of sheep in a household in Yizhou district,Hami City.【Methods】Lung tissue samples of dead sheep were collected,and bacterial isolation and cultivation,real-time fluorescent quantitative PCR,conventional PCR as well as gene sequencing and analysis were performed.【Results】Mycoplasma was cultured successfully on the surface of improved PPLO solid medium.Positive results of Mycoplasma infection were found by real-time fluorescent quantitative PCR.According to PCR amplification and gene sequencing results,the sequence of the isolate had 100% homology with that of Mycoplasma arginine registered in GenBank database.【Conclusion】A Hami strain of Mycoplasma arginine was successfully isolated.
