Bobwhites were experimentally infected with Histomonas meleagridis and Heterakis gallinarum. Chickens and turkeys were similarly infected for comparison. Although the bobwhites were nearly as susceptible to Histomonas infections as were New Hampshire chickens, and more susceptible to tissue invasion, clinical histomoniasis was much less severe than in young turkeys. The bobwhites were poor hosts for Heterakis, whether Histomonas was also present or not. Thus, it appears that bob-whites are relatively unimportant in contaminating soil with Histomonas-bearing Heterakis eggs.
