中文摘要:

      [目的]为了解河南省犊牛腹泻主要病原流行情况和腹泻病因,有效防控犊牛腹泻,加快养牛业健康发展。[方法]用ELISA方法对从河南省12个地区采集1～6月龄有腹泻临床症状和无腹泻临床症状犊牛粪便样品187份,血液样品305份进行检测。[结果]在305份血液样品中,共检测到病毒性腹泻病毒(BVDV)阳性血样17份；副结核分支杆菌阳性血样13份。187份粪便样品中,检测到微小隐孢子虫阳性样品47份；轮状病毒阳性样品3份；大肠杆菌K99⁺阳性样品8份；冠状病毒阳性样品5份。[结论]发现犊牛腹泻主要是由病原感染引起的,其中微小隐孢子虫的感染率为较高,同时以单一病原感染为主。

英文摘要:

      In order to understand the epidemic situation and etiology of calf diarrhea in Henan Province, effectively prevent and control calf diarrhea, and accelerate the healthy development of cattle industry. 187 faeces and 305 blood samples from 1-6 months old calves with and without diarrhea were collected from 12 areas of Henan Province and were detected by ELISA. Among 305 blood samples, 17 were positive for BVDV and 13 for Mycobacterium paratuberculosis. 47 of them were Cryptosporidium, 3 of them were rotavirus positive, 8 of them were Escherichia coli K99+ and 5 of them were coronavirus positive in 187 fecal samples. It was found that the diarrhea of calves was mainly caused by pathogenic infection, in which Cryptosporidium infection rate was high, and single pathogenic infection was the main cause.
