摘要

目的 为调查树鼩消化道寄生原虫感染情况,评价其潜在的公共卫生风险。 方法 分别于2024年5月18日和7月20日从昆明某实验动物养殖基地所饲养的树鼩中随机选取108只,逐只采集其新鲜粪便样品,分别采用直接涂片法、饱和盐水溶液漂浮法和卢戈氏碘液染色法对粪便样品进行检测,对消化道原虫感染情况进行了分析;评估了树鼩的饲养环境,分析了环境卫生状况、饲养密度对感染率的影响。 结果 在圈养条件下人工驯养的树鼩感染原虫主要是鞭毛虫,感染情况非常严重,平均感染率为85%(92/108)。接触污染源、饲养密度过高可能导致树鼩的免疫力下降,使其更容易感染鞭毛虫。 结论 树鼩的饲养环境是造成消化道原虫感染的重要原因之一,应当改善饲养环境,加强卫生管理,才能降低树鼩鞭毛虫感染的风险。

Abstract

Objectives The infection of digestive tract protozoa in tree shrews was investigated to evaluate its potential risks in public health and ensure the accuracy and reliability of tree shrews in biomedical researches. Methods 108 tree shrews were randomly selected from an experimental base of animal farming in Kunming on May 18 and July 20, 2024, and fresh fecal samples were collected from each of them. Direct smear method, saturated saline solution floating method, and Lugo's iodine staining method were used to detect fecal samples. The infection of digestive tract protozoa was analyzed. The environment of farming tree shrews was evaluated and the effects of the hygiene and density of farming on the rate of infection were studied. Results The tree shrews artificially domesticated under captive conditions were mainly infected with protozoa including flagellates, and the infection was very severe, with an average infection rate of 85% (92/108). Exposure to pollution sources and excessive density of farming led to a decrease in the immune system of tree shrews, making them more susceptible to infection with flagellates. Conclusions The environment of farming tree shrews is one of the important factors contributing to the infection with digestive tract protozoan. Improving the environment of farming tree shrews and enhancing the management of hygiene are necessary to reduce the risk of tree shrews being infected with flagellates.
