الملخص EN

This trial was aimed to determine the prevalence of renal coccidiosis in domestic geese and ducks in Nineveh governorate, Iraq.

one hundred and thirty birds of both sexes and different ages were randomly purchased from many localities of Nineveh governorate during the period between 2017 and 2018.

according to geese and ducks' age, the overall infection was 70% and 51.66%, respectively, 74.35% for geese and 53.19% for ducks < 6 months, 64.51% and 46.15% for ≤ 7 months.

sex distribution of renal coccidiosis showed that 75.55%, 54.05% of female geese and ducks, and 60%, 47.82% of male geese and ducks were positive, respectively.

impression smears from kidneys for the presence of eimeria truncata in geese showed that 49 (70 %) were positive, while 31 (51.66%) were positive for ducks.

cloacal fecal samples for eimeria truncata oocytes' were tested by flotation technique revealed that 22.85% were positive for geese and 16.66% for ducks.

the dimensions of eimeria truncata development stages (schizonts, macrogametes, microgametes, and oocytes) were measured.

the histological sections of the infected geese and ducks' kidneys showed the different developmental stages of the eimeria truncata parasite with various pathological changes.
