Mesocestoides sp. in Wild Northern Bobwhite ( Colinus virginianus) and Scaled Quail ( Callipepla squamata).

Mesocestoides spp. have a cosmopolitan distribution with zoonotic potential. Mesocestoides tetrathyridia were found under the pericardial sac, on the surface of the crop, and in the peritoneal cavity of a hunter-harvested Northern Bobwhite ( Colinus virginianus) and a Scaled Quail ( Callipepla squamata) collected during the 2016-17 quail hunting season in northwest and southern Texas, US respectively.
