Principales helminthoses des bovins: enquête épidémiologique au niveau de deux abattoirs de la région d'El Tarf (Algérie)
Abstract
Main Cattle Helminthosis: Epidemiological Investigation at Two Slaughters in the Area of El Tarf Algeria. From July 2010 to December 2011, an epidemiological survey on the main cattle helminthosis was conducted and involved a total of 821 cattle slaughtered at the abattoirs of Ain El Assel and Bouteldja. The results indicate that fasciolosis, hydatidosis and oesophagostomosis dominate with prevalences of 52.4%, 30.9% and 31.3% respectively. Coexist with these pathologies: paramphistomosis, haemonchosis, dictyocaulosis and monieziosis with prevalences of 19.2%, 17%, 15.4% and 11.1% respectively. Overall, the intensity of these parasitic entities is low. The origin of cattle does not affect significantly the prevalence of these pathologies (p≥ 0.05). However it is noted that Ain El Assel and Bouteldja are the most affected areas. Females and cattle over 5 years are the most infested, except for oesophagostomosis where young males (1-3 years) seem the most infested. In addition, all entities are observed throughout the year except for haemonchosis and monieziosis which disappear in December, dictyocaulosis which is absent in January and paramphistomosis which is not observed in January and February.
