Factors of Susceptibility of Human Myiasis Caused by the New World Screw-Worm,Cochliomyia hominivoraxin São Gonçalo, Rio de Janeiro, Brazil

Abstract

This study was carried out between July 2007 and June 2008 and reports on the occurrence of human myiasis caused by the New World screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) in São Gonçalo in the state of Rio de Janeiro, Brazil. Liquid or solid vaseline was used to suffocate the larvae, which were then preserved in 70% ethanol and sent to the Instituto Oswaldo Cruz for identification. C. hominivorax were identified in all 22 cases of myiasis. There were 12 male and 10 female patients with ages ranging from 03 to 71. Ethnically the highest incidence was among black people, with 17 cases. Open wounds were the main cause of the parasitosis, whereas poor personal hygiene, the low educational level, alcoholism, bedridden patients, and physical or mental disability were possibly secondary factors; in addition to all these factors the income of the patients was very low.

Human wound myiasis caused by Phormia regina and Sarcophaga haemorrhoidalis in Minia Governorate, Egypt

“…In this study, the infestations of the patients were all on lower limbs. These results agree with the previous studies showing that the lower limbs were affected more frequently as reported by Nascimento et al (2005), Marquez et al (2007), and Batista-da-Silva et al (2011).…”

“…Similarly, Dokur et al (2015) reported two cases of myiasis in rural areas of southeast Turkey. Abundant household animals and unhealthy environment also participate in the emergence of new cases of myiasis (Batista-da-Silva et al 2011). Thus, it should be considered as Ban occupational disease^among farmer and shepherds.…”

Nosocomial Myiasis Caused by Lucilia sericata (Diptera: Calliphoridae) in a Pediatric Patient in Mexico

“…Nosocomial infestations may also imply broader negligence on the part of the hospital authorities and possible failures in the sanitary and structural conditions of the hospital. is negligence could be grounds for legal action, involving significant losses for hospitals if it is sued for negligence [27,28]. In our case, this was the first case of nosocomial myiasis at a specialty hospital.…”

Human Myiasis

“…Larvae can be deposited in the eye causing painful ophthalmomyiasis resembling a foreign body in the eye sensation. Inflammatory reaction at the site if larviposition due to mast cell activation and IgE production may limit larval development [30]. Larvae accidentally ingested in mouth can be present in oral cavity in the damaged gums and teeth spaces.…”
