Description
Summary:SINCE Graybill and Smith's discovery 1 of the transmission of Histomonas meleagridis , the pathogenic protozoon of enterohepatitis (blackhead) of fowl, by the embryonated egg of the nematode Heterakis gallinæ , a good deal of attention has been given to the hyperparasitism of this nematode. Innumerable experiments have shown that feeding embryonated Heterakis eggs to susceptible birds almost invariably results in a fatal infection of Histomonas ; but all attempts to demonstrate the actual organism in the egg have proved futile.
