The present study was conducted in Jul 2019 and Jan 2020 in two wildlife parks of the Nowshera district, Khyber Pakhtunkhwa, Pakistan, where the endangered Punjab urial () is successfully bred in captivity. We determined diversity of internal and external parasites that take advantage of the situation of congestion, resulting in massive mortalities of wild animals in captivity.
Internal parasites of living urial were determined by direct wet smear and flotation methods, while dead urial was necropsied for any pertaining observation.
All examined fecal samples were found infected with gastrointestinal parasites, which had significant difference in the total abundance in winter and summer. and and a single protozoan, spp. were the dominant parasites in fecal samples. Ticks collected from urial enclosures and dead animals were of single species . spp. was observed in blood, while hydatid cysts were found in lungs and liver of necropsied urial.
The study indicates that internal parasites such as and , while external parasites as ticks played major role in the population decline. Strict veterinary control of infectious diseases, provision of hygienic and supplementary diet, and proper maintenance of urial population are necessary measures for the control of mortalities.
本研究于2019年7月和2020年1月在巴基斯坦开伯尔-普赫图赫瓦省瑙谢拉区的两个野生动物公园进行,濒危的旁遮普捻角山羊()在那里成功圈养繁殖。我们确定了利用拥挤状况的内外寄生虫的多样性,这导致圈养野生动物大量死亡。
通过直接湿涂片法和浮选法确定活捻角山羊的体内寄生虫,对死亡捻角山羊进行尸检以进行相关观察。
所有检测的粪便样本均被发现感染了胃肠道寄生虫,其总丰度在冬季和夏季有显著差异。和以及一种原生动物, spp. 是粪便样本中的主要寄生虫。从捻角山羊围栏和死亡动物身上采集的蜱为单一物种。 spp. 在血液中被观察到,而在尸检的捻角山羊的肺和肝脏中发现了包虫囊肿。
该研究表明,诸如和等体内寄生虫以及蜱等体外寄生虫在种群数量下降中起主要作用。严格的兽医传染病控制、提供卫生和补充饮食以及妥善维持捻角山羊种群是控制死亡率的必要措施。
