Abstract

The developmental process of a Cryptosporidium isolated in Japan in the chicken intestine was investigated by scanning (SEM) and transmission electron microscopies (TEM). The parasites were detected in the ileum, cecum, colon, cloaca and bursa of Fabricius (BF). The intensity of infection tended to peak later in the BF than ileum. Trophozoites and schizonts were detected in all the portions of intestine, and were dominant in the developmental stages. Although macrogamonts were the secondary dominant stage, they were absent in the ileum and cecum at 60 hr postinoculation (PI). A few microgamonts were detected in the ileum at 36 hr PI and in the BF on day 19 PI. Oocysts were observed in the ileum at 48 hr PI and in the BF on day 19 PI.

摘要

通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）对在日本从鸡肠道中分离出的一种隐孢子虫的发育过程进行了研究。在回肠、盲肠、结肠、泄殖腔和法氏囊（BF）中检测到了这些寄生虫。法氏囊中感染强度的峰值往往比回肠出现得晚。在肠道的所有部位都检测到了滋养体和裂殖体，且它们在发育阶段占主导地位。尽管大配子体是第二主导阶段，但在接种后60小时（PI），回肠和盲肠中没有大配子体。在接种后36小时，回肠中检测到少量小配子体，在接种后第19天，法氏囊中检测到少量小配子体。在接种后48小时，回肠中观察到卵囊，在接种后第19天，法氏囊中观察到卵囊。
