在乌干达Bwindi Impenetrable国家公园附近放牧的牛中，研究了隐孢子虫卵囊和贾第鞭毛虫包囊脱落的流行率和强度。隐孢子虫病和贾第虫病的患病率分别为38%和12%，伴随感染为10%。脱落强度从130到450个卵囊/ g（平均215个卵囊/g）和从110到270个卵囊/g（平均156个卵囊/g）变化。显着更多的断奶前比断奶后的牛感染任何一种寄生虫，断奶前的牛脱落的寄生虫数量显着高于断奶后的牛。数学建模表明，在抽样牛中，隐孢子虫病和贾第虫病的无症状感染的最高患病率可分别达到约80%和35%。因为C. parvum和G.从牛身上回收的寄生虫可以感染人和大猩猩，在Bwindi公园内放牧的牛应被视为这些人畜共患寄生虫的重要储存库。
The prevalence and intensity of shedding of Cryptosporidium parvum oocysts and Giardia duodenalis cysts was investigated in cattle grazing in the vicinity of the Bwindi Impenetrable National Park, Uganda. The prevalence of cryptosporidiosis and giardiosis was 38% and 12%, respectively, with 10% concomitant infections. Shedding intensity varied from 130 to 450 oocysts/ g (mean of 215 oocysts/g) and from 110 to 270 cysts/g (mean of 156 cysts/g). Significantly more pre-weaned than post-weaned cattle were infected with either parasite, and the pre-weaned cattle shed significantly higher numbers of either parasite than the post-weaned cattle. Mathematical modeling indicated that the maximum prevalence of asymptomatic infections can reach approximately 80% for cryptosporidiosis and 35% for giardiosis in the sampled cattle. Because C. parvum and G. duodenalis recovered from cattle can infect people and gorillas, cattle that graze within the Bwindi Park should be considered as a significant reservoir of these anthro-pozoonotic parasites.
