Autochthonous Furuncular Myiasis in the United States: Case Report and Literature Review

Abstract

Most cases of furuncular myiasis in the United States are acquired during travel to other countries. Autochthonous cases are infrequently reported and are most often due to accidental infestation of humans by larvae of flies belonging to the genus Cuterebra, commonly known as "rabbit bot flies" or "rodent bot flies." We describe a case of furuncular myiasis due to Cuterebra larvae in the hand of a patient residing in Wisconsin. The infestation was acquired while the patient gardened near a seepage lake during August. The patient developed papular lesions on the hand and received therapy for presumed bacterial furunculosis, which did not lead to improvement. Retrieval of one of the larvae from the patient permitted identification of the causative agent, and application of an occlusive ointment resulted in complete cure. North American cuterebrid myiasis is rare, and the diagnosis is frequently delayed. Myiasis should be considered when treating patients with refractory furunculosis.

Cutanous Myiasis Caused by Sarcophaga spp. Larvae in a Diabetic Patient

“…Dişi sinekler özellikle açık ve bakımsız yaralar üzerine yumurta veya birinci dönem larvalarını bırakırlar. Larvalar birkaç gün içinde üçüncü dönem larva haline gelerek dokularda yıkıma neden olurlar 3,6 . Sarcophagidae ailesindeki en önemli türler ise Sarcophaga ve Wohlfahrtia cinsinde yer alırlar.…”

First Records of Rodent-Infesting Cuterebra Bot Flies Parasitizing Raccoons (Procyon lotor) in North America

“…bot flies (Diptera: Oestridae) are of interest from both the perspective of parasite/host coevolution (Colwell et al 2006;Slansky 2007a) and the context of these insects causing a type of myiasis (cuterebrosis) in cats, dogs, humans, and other mammals (Safdar et al 2003;Slansky 2007b,c;2008). Cuterebra spp.…”

Wound and Conjunctival Myiasis Caused by Lucilia sericata: A Case Report

“…Myiasis is an infestation of vertebrate animals and live humans with dipterous larvae, which feed on the host's tissues (dead or living) or liquid substances (1). The larvae require warm temperature to incubate; thus most infestations are found during summer and in tropical countries (2).…”

“…Myiasis has been classified based on the involved site of the body. The most frequent type is cutaneous myiasis that manifests as wound, migratory or furuncular forms (1). Also other sites of infestation have been reported, such as nasopharyngeal, ophthalmic, urogenital and intestinal (3).…”
