title: Failure of Heterakis bonasae to transmit Histomonas meleagridis.
abstract: Studies were conducted to determine whether Heterakis bonasae eggs from bobwhite quail infected with Histomonas meleagridis would transmit histomoniasis to turkeys. Fifteen helminth-free bobwhites were inoculated per os with embryonated H. bonasae eggs. Each bobwhite was then infected with H. meleagridis via rectal inoculation. Bobwhites that developed cecal lesions rarely retained mature H. bonasae. H. bonasae eggs recovered from bobwhites exposed to or known to have concurrent H. meleagridis infections were inoculated per os to eleven helminth-free turkeys. None of the turkeys developed H. meleagridis infections.
