Morphobiological Studies on Cryptosporidia And Sarcocytis in Animals And Their Impact On Their Health

Cryptosporididistributed among different animal species. Both parasitesbelonging to order E.imeriorina (Leger, 1911). Concerning Cryptosporidia, the percentages of infection detected by faecal examination of buffalo- calves,cattle calves, lambs and kids by using modified Ziehl- Neelsen stain were 6.6%, 8.2%, 5.2% and 2.5% respectively,and those detected by the intestinal smear examination of slaughtered buffalo-calves, lambs and kids using the same stain were 11.3%, 9.4% and 7.6% respectively. The incidenceof infection in buffalo-calves was high in winter (19.1%), then decreased in autumn (12%), followed by spring (11.7%) and summer (3.7%). The most predilection seat of theparasite in different animals was the ileum, then followed by jejunum and duodenum.The morphology of Cryptosporidium oocysts of bufflao- calves was described by using sugar flotation technique and modified Ziehl-Neelsen, safranin methylene blue, methyleneblue-eosin and Giemsa staining techniques. The oocysts werespherical or ovoid bodies, measuring 5.2 - 6.0 x 4.5 - 4.9microns.
