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.
