The prevalence of gastrointestinal helminths of local chickens in Nsukka region of Southeastern Nigeria was studied using 125 free range local birds purchased from four communities in Nsukka zone namely, Obolloafor, Orba, Nsukka urban and Owerre Eze-orba. The birds were sacrificed humanely and their oesophagus, crop, proventriculus, gizzard, small intestine and caecum examined for the presence of gastrointestinal helminths. Worms when present were isolated and identified using standard parasitological procedures. The study identified four species of cestodes namely Raillietina echinobothridia, R. tetragona, R. cesticillus and Choanotaenia infundibulum and two species of nematodes namely, Ascaridia galli and Heterakis gallinarum. Results obtained showed 96.8 % prevalence of gastrointestinal helminth parasites in the birds with cestodes being the more prevalent class (70.4 %). Raillietina spp was the most prevalent cestode encountered and A. galli the most prevalent nematode. Prevalence rates of infections recorded 14.4 % for nematode species, 26.4 % for cestodes and 56 % for mixed infections of nematodes and cestodes. It was concluded that local chickens are common in the area and could serve as a potential source of helminth infections to intensively managed birds in the study area.
