Abstract

BACKGROUND AND OBJECTIVES

Enzootic abortion of ewes (EAE) is caused by infection of sheep and goats by bacterium. Chlamydial abortion in bovine could occur by and is the causative agent of psittacosis or ornithosis disease in humans and birds. It also causes acute pneumonia in cattle and sheep. The present study aimed at surveying the role of chlamydial agents in ruminants abortion.

MATERIALS AND METHODS

A total of 117 aborted material samples (Cotyledon, liver, spleen, and abomasal contents of fetus) from 9 cattle and 100 sheep in Shahr-e-Kord and 8 sheep from Bagh-e-Malek were collected from different herds with abortion history during the lambing periods from 2014 to 2016. After DNA extraction, the samples were tested by species-specific PCR to detect and

RESULTS

Out of 117 clinical sample (108 sheep and 9 cattle), chlamydial infection was detected in 66 (56.41%) samples by order-specific primers. A total of 24 (36.36%) and 24 (36.36%) samples indicated positive forms of and infections, respectively. Only 1 (1.5%) was identified from cattle using nested PCR during this study. Among 66 -positive samples, 20 (30.30%) samples with coinfection of and were detected, however, infection of 3 species was not detected in the samples.

CONCLUSION

Because of the high percentage of chlamydial infection in these regions and probability of coinfection, conducting epidemiological studies on the role of different animals is highly recommended.

摘要

背景与目的

绵羊地方性流产(EAE)是由细菌感染绵羊和山羊引起的。牛的衣原体性流产可能由此引发,且该病原体也是人类和鸟类鹦鹉热或鸟疫的病原体。它还会导致牛和羊的急性肺炎。本研究旨在调查衣原体病原体在反刍动物流产中的作用。

材料与方法

2014年至2016年产羔期,从设拉子-库尔德的9头牛和100只绵羊以及巴格-马利克的8只绵羊中,收集了117份流产材料样本(胎盘、肝脏、脾脏和胎儿皱胃内容物),这些样本来自不同有流产病史的畜群。DNA提取后,样本通过种特异性PCR进行检测,以检测……

结果

在117份临床样本(108只绵羊和9头牛)中,用属特异性引物检测到66份(56.41%)样本存在衣原体感染。分别有24份(36.36%)和24份(36.36%)样本显示存在……和……感染的阳性形式。本研究期间,仅通过巢式PCR从牛中鉴定出1份(1.5%)……。在66份……阳性样本中,检测到20份(30.30%)样本同时感染了……和……,然而,样本中未检测到三种病原体的感染情况。

结论

鉴于这些地区衣原体感染率高且存在混合感染的可能性,强烈建议对不同动物的作用开展流行病学研究。
