Intestinal parasitic infections are major causative agents of wildlife health complications among different parts of the world. This study aimed to investigate the gastro-intestinal parasites in feces of the zoo animals based on parasitological and morphometric criteria.
One hundred fresh fecal samples were collected from 35 species of animal lived in Eram park zoo, Tehran, Central Iran during Oct 2015 to Jun 2015. All collected samples were examined by microscopic observation following direct wet mount preparation (normal saline and Lugol's iodine), formalin-ether concentration, and permanent staining. The morphometric aspects of the recovered eggs were surveyed with the aid of Camera Lucida (×400).
65.7% (23/35) of zoo animal species were infected with intestinal parasites. The superfamily Trichostrongyloidea (6/16) and sp. (16/4) were the most prevalent helminthic infections, while sp. (6/14), cyst (3/14) and sp. (3/14) were the common protozoan parasites. For the first time, egg was identified an elephant at Iran. Intestinal parasitic infections were apparently circulating among animals of the Eram park zoo.
Identified parasitic infections can consider as a threatening source to visitors and workers' health that have contact with animals or their feces. Therefore, the effectual preventive strategies should be addressed to determine the risk factors, mechanisms of cross-transmission of parasite, the importance of applying the hygienic practices and well adjusting deworming programs for the animals, zoo workers and visitors.
肠道寄生虫感染是世界不同地区野生动物健康问题的主要致病因素。本研究旨在根据寄生虫学和形态学标准调查动物园动物粪便中的胃肠道寄生虫。
2015年10月至2015年6月期间，从伊朗中部德黑兰埃拉姆公园动物园生活的35种动物中采集了100份新鲜粪便样本。所有采集的样本均经过直接湿片制备（生理盐水和卢戈氏碘液）、福尔马林-乙醚浓缩和永久染色后进行显微镜观察。借助绘图显微镜（×400）对回收虫卵的形态学特征进行测量。
65.7%（23/35）的动物园动物物种感染了肠道寄生虫。毛圆线虫超科（6/16）和 种（16/4）是最常见的蠕虫感染，而 种（6/14）、 囊肿（3/14）和 种（3/14）是常见的原生动物寄生虫。首次在伊朗一头大象的粪便中鉴定出 虫卵。肠道寄生虫感染显然在埃拉姆公园动物园的动物中传播。
已确认的寄生虫感染可被视为对与动物或其粪便有接触的游客和工作人员健康的威胁源。因此，应制定有效的预防策略，以确定风险因素、寄生虫交叉传播的机制、应用卫生措施的重要性，以及为动物、动物园工作人员和游客妥善调整驱虫计划。
