Abstract

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 2017and 2018. According to geese and ducks' age, the overall infection was 70.00% and 51.66%, respectively, 74.35% for geese and 53.19% for ducks 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.

Highlights

Coccidiosis is a worldwide disease caused by a single celled parasite belonging to the phylum Apicomplexa, family Eimeriidae
The age of birds tested for renal coccidiosis influences the prevalence of their infectivity in both types, geese, and ducks
From the Table, it is evident that goslings and ducklings less than 6 months of age had a higher prevalence of renal coccidiosis compared to those of 7 and more

Summary

Introduction

Coccidiosis is a worldwide disease caused by a single celled parasite belonging to the phylum Apicomplexa, family Eimeriidae. Intestinal coccidiosis in geese and ducks was reported here in Iraq In Iraq and here in Nineveh governorate, the usefulness of ducks and geese in providing a part of the animal protein urged the population in breeding these kinds of birds in small herds on farms and homes. Most renal coccidiosis reports in ducks and geese are asymptomatic birds or birds that show minor physiological or pathological changes due to the parasite. Young birds and those stressed by various conditions are most likely to have clinical cases of renal coccidiosis. Disease in domestic geese is usually acute, lasts only 2-3 days, and can kill large flock segments [12,13]
