Prevalence of nematode parasites in cattle egret (Bubulcus Ibis)‎ in Egypt

الملخص EN

The present study was aimed to determine the nematode parasites infesting cattle egrets (Bubulcus ibis) and its role in maintenance of such parasites in nature or transmission of these parasites to other species of wild birds and domestic birds, mammals, fish and human being especially after dramatic increase of cattle egret's population inside the urban areas.

During this study, a total of 106 cattle egrets (Bubulcus ibis) were examined and eight species of nematodes were detected.

The detected species; Desportesius invaginatus (85.84%), Microtetrameres spiralis (67.92), Porrocaecum sp.

(26.41%), Microtetrameres helix (23.58%), Tetrameres sp.

(10.37%), Microfilaria (2.83%), Gnathostoma sp.

larvae (1.88%) and Anisakis sp.

larvae (0.94 %).

Five factors (habitat, area of collection, sex, age and season) affecting the prevalence of nematodes in cattle egrets as well as the pathological effects of these parasites on cattle egrets were studied
