Toxoplasma gondii in Chickens (Gallus domesticus) from North India. Acta Parasitol. (IF 1.019) Pub Date : 2020-08-28 Rashmi Thakur,Rajnish Sharma,Rabinder Singh Aulakh,Balbir B Singh
PURPOSE Toxoplasma gondii, an important food-borne parasite has been reported in a wide range of food animals globally. Poultry meat production is on rise in several developing nations including India. Several studies on status of T. gondii conducted globally had shown substantial risk of this parasite through poultry meat. Such information is lacking in the north India, where poultry meat is a preferred
