ABSTRACT
An epidemiological study was conducted for investigation of bovine coronavirus by antigen Enzyme-linked immunosorbent assay kit in dairy calves from Central India (Madhya Pradesh and Chhattisgarh states) and North India (Uttar Pradesh state). Different epidemiological parameters like age, parity, colour and consistency of faecal materials and seasonal changes in a year were recorded. A total of 816 faecal samples were screened and out of which 7 (0.85%) animals were found to be positive for bovine coronavirus. The higher prevalence was recorded in north India followed by central India. Age wise higher prevalence was recorded below 2 month calves. Seasonally, the prevalence of coronavirus infection was higher in monsoon season and in first parity of calves as compared to other season and parity. Prevalence of coronavirus infection was higher in watery diarrhoea faecal materials than pasty yellow colour diarrhoea. The observations of the present study would provide the basis for further an effective explorative surveillance and epidemiological studies to know the real impact of coronavirus infection with associated risk factors in dairy calves of India.

印度中部和北部地区有组织的奶牛场中牛冠状病毒感染的流行率
摘要
对来自印度中部(中央邦和恰蒂斯加尔邦)和北印度(北方邦)的奶牛进行了一项流行病学研究,通过抗原酶联免疫吸附测定试剂盒对牛冠状病毒进行调查。记录了不同的流行病学参数,如粪便材料的年龄、胎次、颜色和稠度以及一年中的季节变化。共筛查了 816 份粪便样本,其中 7 只(0.85%)动物的牛冠状病毒呈阳性。印度北部的患病率较高,其次是印度中部。在 2 个月以下的犊牛中记录了较高的患病率。季节性地,与其他季节和胎次相比,季风季节和初胎犊牛的冠状病毒感染率较高。水样腹泻粪便材料中冠状病毒感染的患病率高于糊状黄色腹泻。本研究的观察结果将为进一步有效的探索性监测和流行病学研究提供基础,以了解冠状病毒感染与相关风险因素对印度奶牛的真正影响。
