Over 100,000 goats were grazing freely in isolated herds of 100 to 600 goats in a mountainous area of more than 2000 km2 to the north-east of Darab City in Fars Province in southern Iran. Twenty to fifty percent of the goats in this area were infected with besnoitiosis. Sheep, cattle and donkeys grazing in the same area showed no clinical manifestations of the infection. The diagnosis of the infection in the clinically suspected animals was confirmed by histological studies on skin biopsies from the ear tips and carpal and tarsal regions, and the distribution of this protozoon in the tissues and organs of this intermediate host was studied by post-mortem and histological examinations. Skin biopsies from the carpal and tarsal areas of 12% of clinically normal goats from the infected area were also lightly infected with besnoitia cysts.
在伊朗南部法尔斯省达拉布市东北一个面积超过2000平方公里的山区，10多万只山羊以100至600只的孤立畜群自由放牧。该地区20%至50%的山羊感染了贝诺孢子虫病。在同一地区放牧的绵羊、牛和驴没有表现出该感染的临床症状。通过对来自耳尖、腕部和跗部区域的皮肤活检进行组织学研究，证实了临床疑似动物的感染情况，并通过尸检和组织学检查研究了这种原生动物在该中间宿主组织和器官中的分布。来自感染地区12%临床正常山羊的腕部和跗部区域的皮肤活检也轻度感染了贝诺孢子虫囊肿。
