A review on the occurrence of Cochliomyia hominivorax (Diptera: Calliphoridae) in Brazil

Abstract

Cochliomyia hominivorax (Coquerel, 1858), the New World screwworm, causes primary myiasis in wild and domestic animals in tropical and subtropical regions of Brazil. Although this species is considered to occur throughout the country, organized information about its recorded distribution has not been available until now. This article aimed to provide a comprehensive review of the historical and current data published on both immature (myiasis) and adult stages of C. hominivorax in Brazil. A total of 174 articles were found; of these, 141 articles reported myiasis cases in cattle (146 records), humans (68 records), and other mammalian hosts (40 records), and captures of adult flies were reported in 33 articles. C. hominivorax is widespread in Brazil, having been recorded in 208 municipalities in all major biomes of the country.

Myiasis by <i>Cochliomyia hominivorax</i> (Coquerel, 1858): A Neglected Zoonosis in Brazil

“…This fly is the main cause of primary myiasis in both animals and humans in the country [4] [5] [6]. These conditions are commonly named "screwworm" and cause extremely bloody and aggressive injuries, mainly because they have very fast clinical evolution.…”

Primary Myiasis in Surgical Wound of Mandible Symphisis Fracture

“…e smear and culture results were negative for Baar culture and were available a er the healing period, thus revealing that the empiric antibiotics were e cient. e larvae were not identi ed, but epidemiologically, the larvae that mostly a ect the southeast region of Brazil (Minas Gerais-MG) are usually classi ed as Cochliomyia hominivorax (Diptera: Calliphoridae) [18]. e local health care system, although having a social support, it is usually performed during the period of hospitalization of the patient.…”

Historical perspective and new avenues to control the myiasis-causing fly Cochliomyia hominivorax in Uruguay

“…Currently, NWS infestations remain a serious problem for animal health in South America. Costa-Junior and others (103) reviewed the literature on occurrence of both larvae (myiasis-causing development stage) and adults in Brazil concluding that NWS fly is the most important cause of primary myiasis in livestock, pets and human beings, and it is distributed throughout the country. Other epidemiological reports in South America have shown the prevalence and incidence of the NWS fly, indicating its importance in a tropical area in Ecuador (104) , and have revealed that is widespread in Venezuela representing a serious threat to the livestock industry, as well as to the human population (55) .…”
