In June 2005, we collected 115 fecal samples from wild primates in western Uganda and examined them for Cryptosporidium sp. and Giardia sp. with the use of immunofluorescent antibody (IFA) detection. We sampled primates from an undisturbed forest in Kibale National Park and from 3 highly disturbed forest fragments outside the park. Of disturbed forest samples, red colobus (Pilocolobus tephrosceles) and red-tailed guenons (Cercopithecus ascanius) harbored species of Cryptosporidium or Giardia, but black-and-white colobus (Colobus guereza) did not. All primate samples from undisturbed forest were negative for both parasites. Seven of 35 (20%) red colobus and 1 of 20 red-tailed guenons (5%) from forest fragments were infected with either Cryptosporidium sp. or Giardia sp. The presence of Cryptosporidium and Giardia species in primates living in forest fragments, but not in primates in undisturbed forest, suggests that habitat disturbance may play a role in transmission or persistence of these pathogens.
2005年6月，我们从乌干达西部的野生灵长类动物身上采集了115份粪便样本，并使用免疫荧光抗体（IFA）检测法对其进行隐孢子虫属和贾第虫属检测。我们从基巴莱国家公园一片未受干扰的森林以及公园外3个受严重干扰的森林碎片区域采集了灵长类动物样本。在受干扰森林的样本中，红疣猴（Pilocolobus tephrosceles）和红尾长尾猴（Cercopithecus ascanius）体内携带隐孢子虫属或贾第虫属的某些物种，但黑白疣猴（Colobus guereza）体内未检测到。来自未受干扰森林的所有灵长类动物样本对这两种寄生虫检测均呈阴性。来自森林碎片区域的35只红疣猴中有7只（20%）以及20只红尾长尾猴中有1只（5%）感染了隐孢子虫属或贾第虫属。生活在森林碎片区域的灵长类动物体内存在隐孢子虫属和贾第虫属，而未受干扰森林中的灵长类动物体内没有，这表明栖息地干扰可能在这些病原体的传播或持续存在中发挥作用。
