Abstract

The present study was conduct to detect the prevalence and the seasonal dynamic of protozoa infection among domesticated poultry (chicken, turkey, duck, geese and pigeon). The detected protozoa were Eimeria spp. in fowl, pigeon and duck and Cryptosporidium spp. The current study revealed that out of 1486 examined birds 636 (42.8%) were infected with intestinal protozoa. The incidences rate were 401 (62.3%) in fowls, 149 (46.2%) in pigeons, 96 (10.9%) in turkeys, 74 (18. 3%) in ducks and 3 (8.3%) in geese. The seasonal dynamic revealed that the highest incidence of Eimeria and Cryptosporidium in all examined bird species was in Winter (61.5%, 15.4%), (42%, 3.6%), (14.1%, 44.2%), (15.7%) and (30%) for (fowl, pigeon, duck, turkey and geese respectively) while the lowst rate in Eimeria spp and Cryptosporidium in fowl was in Summer (36.3%) and Spring (8.3%) respectively. The lowest rate of protozoa in pigeons was in spring (20.4, 2.6%). Eimeria and Cryptosporidium showed fewer incidences in autumn (2.4%) and summer (3.2%) in ducks. Cryptosporidium had lowest rate in autumn in turkey (4.4%).
