Digestive parasites of local hens sold in Ngaoundere (Cameroon) ; Parásitos digestivos de las gallinas de pueblo vendidas en Ngaoundéré (Camerún) ; Parasites digestifs des poules villageoises vendues à Ngaoundéré (Cameroun)

A study was conducted on the digestive parasitism of local hens collected in two markets in the city of Ngaoundéré (Cameroon) between May and August 2018. Nine genera (Eimeria sp., Raillietina sp., Capillaria sp., Choanotaenia sp., Gongylonema sp., Amoebotaenia sp., Hymenolepis sp., Tetrameres sp. and Echinostoma sp.) and three species (Ascaridia galli, Heterakis gallinarum and Trichostrongylus tenuis) were identified. Of the 429 samples examined, 362 carried one or more parasites for an infestation rate of 84.4%. This rate was 86.3% in the 240 birds examined by coproscopy, and 82.0% in the 189 birds examined by necropsy. At coproscopy, adult birds were more infested than young birds with Ascaridia galli, Raillietina sp. and Eimeria sp. Similarly, at necropsy a higher prevalence of Capillaria sp. and Raillietina sp. was observed in adults. Most helminths were parasitizing the small intestine. No lesions of Coccidia were observed along the intestinal tract. Various associations of parasites were observed, with Eimeria sp. predominating. The average intensity of infestation by Eimeria sp., estimated by McMaster’s egg per gram of feces method, was highest in adult birds. ; Se llevó a cabo un estudio sobre el parasitismo digestivo de las gallinas de pueblo recolectadas en dos mercados de la villa de Ngoundéré (Camerún) entre mayo y agosto 2018.

Sobre las 429 muestras examinadas, 362 fueron portadoras de uno o más parásitos, o sea una tasa de infestación de 84,4%. Esta tasa fue de 86,3% en las 240 aves examinadas por examen coprológico y de 82,0% en las 189 examinadas por autopsia.
