伊氏李氏杆菌引发奶牛流产的诊断

摘要

李氏杆菌是引起家畜流产的主要传染性病因之一,其中单核细胞增生性李氏杆菌和伊氏李氏杆菌是引起奶牛李氏杆菌病的主要致病菌,主要引起动物脑膜脑炎、败血症和孕畜流产、死胎或新生畜感染等症状.本实验室于2010年4月接到北京某牛场流产病例样品3份(包括流产胎儿、胎盘及母牛血样),经胎儿组织抹片染色、细菌分离培养与鉴定以及鉴别诊断,最终确诊该3例流产病例为伊氏李氏杆菌感染所致.%Listeria is one of the major abortifacient infectious agents in livestock. Among the Listeria spp., Listeria monocytogenes and Listeria ivanovi are the causative agent of listeriosis, mainly cause meningoencephalitis, septicemia, abortion, stillbirth or infection in newly born animal, etc. In April 2010, samples of three abortion cases were collected(including the fetus, placenta and blood sample of the dam). Stain of the fetus' tissues, bacteria isolation/culture and identification were conducted, in addition, differential diagnosis were done. Finally, these three cases were diagnosed as Listeria ivanovi infection after these diagnostic tests.
