RESUMO
There is scarce data available on helminth infection of poultry in the region of Aswan province, Upper Egypt. A total of 276 poultry (156 baladi chickens and 120 domestic pigeons) were collected from different villages in Aswan province to screen the presence of intestinal helminths during the period from April 2016 to March 2017. The current investigation revealed that the overall prevalence was 55.79% (154/276). Additionally, 59.09% baladi chickens had mixed infections with four cestodes and three nematodes. Among cestodes, Raillietina tetragona was the most prevalent species (16.02%) followed by Raillietina echinobothrida (10.98%), Cotugnia digonopora (6.41%), and Raillietina cesticillus (1.28%). The most prevalent nematodal species were Heterakis gallinarum (15.38%), Ascaridia galli (8.97%), and Subulura brumpti (1.28%). In pigeons, 52.5% were found to be infected by four cestodes: Raillietina echinobothrida (22.5%), Cotugnia digonopora (13.33%), Raillietina tetragona (9.16%), and Raillietina cesticillus (3.33%) as well as one species of nematodes, Ascaridia columbae (9.16%). There was a close relationship between the occurrence of intestinal helminths and the age of domestic birds revealing that the high prevalence was found in adults rather than young birds. Meanwhile, it has been found that the highest prevalence was found in summer, while the lowest infection rate was recorded in winter. Further studies are needed to determine the effects of the parasites on the health and productivity of poultry in such area.
