Double Infestation of a Varicose Ulcer with Screw-worm and House Fly Maggots


The individual whose case is summarized presented himself with a necrotic varicose ulcer of the lateral aspect of the right leg in which maggots of Callitroga americana and of Musca domestica were living in symbosis. The Callitroga maggots had penetrated deeply into healthy muscle and fibrous tissue and were feeding avidly on normal tissue. The muscoid maggots were present superficially feeding in the necrotic material much of which was being provided by the activity of the Callitroga maggots.
