Abstract

This study was undertaken to detect Trypanosoma evansi infection in clinically ill cattle, buffaloes and horses that were suspected of 'surra' infection. Various diagnostic tests were utilized in order to assess the prevalence of infection in the clinically ill and 'suspected' animals. Animals in the Eastern Region of India were systematically studied for T. evansi infection, which had not been tested for previously. Examination of Giemsa-stained blood smears detected 5.3%, 9.4% and 40.6% infections; the mouse inoculation test detected 18.4%, 15.6% and 46.9% infections whereas an in-house ELISA detected anti-trypanosomal antibodies in 42.1%, 43.8% and 65.6% infections in clinically ill buffaloes, cattle and horses, respectively. It can be concluded that T. evansi is prevalent in cattle, buffaloes and horses in the Eastern Region of India.

摘要

本研究旨在检测临床患病且疑似感染“苏拉病”的牛、水牛和马中的伊氏锥虫感染情况。为评估临床患病及“疑似”动物的感染率，采用了多种诊断检测方法。对印度东部地区此前未检测过伊氏锥虫感染的动物进行了系统研究。经吉姆萨染色血涂片检查，感染率分别为5.3%、9.4%和40.6%；小鼠接种试验检测到的感染率分别为18.4%、15.6%和46.9%，而一种内部酶联免疫吸附测定（ELISA）分别在临床患病的水牛、牛和马中检测到抗锥虫抗体的感染率为42.1%、43.8%和65.6%。可以得出结论，伊氏锥虫在印度东部地区的牛、水牛和马中普遍存在。
