Abstract

For behavioral research and due to growing ecotourism, some populations of free-ranging mountain gorillas (Gorilla gorilla beringei) have become habituated to humans. Molecular analysis of two Cryptosporidium sp. oocyst isolates originating from two human-habituated gorilla groups and two oocyst isolates from non-habituated gorillas yielded positive identification of C. parvum Genotype 2 (G2; i.e., "cattle", "animal-adapted", or "zoonotic"). As G2 is cross-transmissible between humans and animals, C. parvum infections can be propagated in the habitats of human-habituated, free-ranging gorillas through both zoonotic and anthroponotic transmission cycles.

摘要

对于行为研究以及由于生态旅游的不断发展，一些自由放养的山地大猩猩（Gorilla gorilla beringei）种群已经习惯了人类的存在。对来自两个习惯与人类接触的大猩猩群体的两种隐孢子虫属卵囊分离株以及来自不习惯与人类接触的大猩猩的两种卵囊分离株进行分子分析，结果明确鉴定出微小隐孢子虫基因型2（G2；即“牛型”、“动物适应型”或“人畜共患型”）。由于G2可在人和动物之间交叉传播，微小隐孢子虫感染可通过人畜共患和人传人传播循环在习惯与人类接触的自由放养大猩猩栖息地中传播。
