ABSTRACT

Porcine teschoviruses (PTVs) belong to the genus Teschovirus within the family Picornaviridae had 13 serotypes linked with a variety of clinical diseases. The objective of the present study was to detect the epidemiological data’s of PTV in Bareilly district of Uttar Pradesh (UP), India. Different epidemiological parameters such as age, sex and seasonal changes from February 2015 to February 2016 were recorded. A total of 106 faecal/intestinal contents samples were screened for PTV infection using reverse transcription polymerase chain reaction (RT-PCR) assay. Based on the RT-PCR assay of the faecal/intestinal samples, 19.8% (21/106) samples were positive for PTV. Out of 21 positive cases, 11.1% (5/45) were necropsied animals, 32.5% (14/43) from faecal sample collected from swine production farm and 11.76% (2/17) were intestinal contents of slaughtered animal. Age-wise highest prevalence was found in nursery age group 32.6% (17/52) followed by adult age group 13.3% (4/30) and was absent in suckling piglets in the current study. Sex-wise prevalence was recorded higher in males, 25% (12/48), than in females, 15.51% (9/58). Seasonally, prevalence was highest in winter than in summer. Prevalence of PTV is more in healthy pigs than in diarrhoeic pigs. The observations of the present study would provide a basis for a further extensive epidemiological and pathogenicity studies of PTV circulating in swine population of India.

印度北方邦 Bareilly 猪感染猪嗜热菌病毒的流行病学研究

摘要

猪特斯科病毒 (PTV) 属于特斯科病毒在小核糖核酸病毒科中,有 13 种血清型与多种临床疾病有关。本研究的目的是检测印度北方邦 (UP) 巴雷利地区 PTV 的流行病学数据。记录了 2015 年 2 月至 2016 年 2 月不同的流行病学参数,例如年龄、性别和季节变化。使用逆转录聚合酶链反应 (RT-PCR) 测定法对总共 106 份粪便/肠道内容物样本进行 PTV 感染筛查。根据粪便/肠道样本的 RT-PCR 分析,19.8% (21/106) 的样本对 PTV 呈阳性。在 21 例阳性病例中,11.1% (5/45) 为尸检动物,32.5% (14/43) 来自养猪场收集的粪便样本,11.76% (2/17) 为屠宰动物的肠道内容物。在保育年龄组中发现年龄最高的患病率 32.6% (17/52),其次是成年年龄组 13.3% (4/30),并且在目前的研究中没有哺乳仔猪。男性的性别患病率记录为 25% (12/48),高于女性的 15.51% (9/58)。季节性地,冬季患病率高于夏季。健康猪的 PTV 患病率高于腹泻猪。本研究的观察结果将为印度猪群中流行的 PTV 的进一步广泛的流行病学和致病性研究提供基础。健康猪的 PTV 患病率高于腹泻猪。本研究的观察结果将为印度猪群中流行的 PTV 的进一步广泛的流行病学和致病性研究提供基础。健康猪的 PTV 患病率高于腹泻猪。本研究的观察结果将为印度猪群中流行的 PTV 的进一步广泛的流行病学和致病性研究提供基础。
