Abstract

This is the first report on Eimeria leuckarti infection in foals in Japan. Seven Thoroughbred or Angloarabian foals 2 to 7 months of age raised in the Hidaka district, Hokkaido, were infected with E. leuckarti. They died of severe alterations caused by the larval migration of Strongylus vulgaris, and were examined over a period from 1970 to 1973. Protozoa of this species were observed in the small intestine in all the foals. They were found mostly in vacuoles of the cytoplasm of monoclear cells in the lamina propria at or near the tip of villi. Various stages of gametocytes, oocysts, and microgametocytes were found. In infected cells the nucleus was markedly enlarged, but the cellular response was very slight to the parasite.

摘要

这是日本关于马驹感染鲁氏艾美耳球虫的首次报告。在北海道日高地区饲养的7匹2至7月龄的纯种马或英阿拉伯马驹感染了鲁氏艾美耳球虫。它们死于普通圆线虫幼虫移行引起的严重病变，并在1970年至1973年期间接受了检查。在所有马驹的小肠中均观察到该物种的原生动物。它们大多存在于绒毛尖端或其附近固有层单核细胞细胞质的液泡中。发现了配子体、卵囊和小配子体的各个阶段。在受感染的细胞中，细胞核明显增大，但细胞对寄生虫的反应非常轻微。
