“…Thus, it should be considered as Ban occupational disease^among farmer and shepherds. Myiasis is recorded frequently in tropical and semitropical countries, especially in rural areas where people live in close contact with their domestic animals (Graffi et al 2013;Demirel Kaya et al 2014). …”

“…In addition, myiasis infestation occurs preferably during the summer, a favorable period for the reproduction of the flies (Graffi et al 2013;Demirel Kaya et al 2014). All cases in the present study occurred during the summer, when the density of fly population is the greatest, like many other reports (Sesterhenn et al 2009;Maleki-Ravasan et al 2014;Demirel Kaya et al 2014).…”

Myiasis is the parasitic infestation of human by the larvae (maggots) of dipterous fly that grow within the host while feeding on its tissue. Cutaneous myiasis is the most considerably encountered clinical form. Moreover, wound (traumatic) myiasis is the main clinical manifestation of cutaneous myiasis. In this research, we aimed to study the type of infesting larvae that are responsible for wound myiasis in the patients in Minia city, Egypt. Three cases of wound myiasis have been noticed among 280 patients with wounds at different parts of bodies. Two of them were diabetic patients. The third one had a history of hypertension with right side hemiplegia 2 years ago. All of them were elderly. The larvae removed from cases 1 and 3 were identified macroscopically and microscopically as the third-stage larvae of Sarcophaga haemorrhoidalis. The larvae removed from case 2 were the third-stage larvae of Phormia regina, which is very rare worldwide. In addition to the open and obsolete wound, diabetes mellitus and low socio-economic circumstances were shown to be attributed as important predisposing risk factors that led to the occurrence of myiasis in these patients.

“…Similarly, Verma et al (1990) reported the association of ophthalmomyiasis caused by C. bezziana with the virus Herpes zoster. Another rare case of ophthalmomyiasis by Sarcophaga argyrostoma was reported by (Graffi et al 2013). The elk throat botfly, Cephenemyia ulrichii, had also been reported to cause human ophthalmomyiasis from Finland (Mikkola et al 1982).…”

Incidence of myiasis among humans—a review

Myiasis, the infestation of tissues of live humans and other vertebrate animals with dipteran larvae (maggots), is a phenomenon of widespread occurrence throughout the tropical regions of the world. It is commonly seen in domestic and wild animals but occurs rarely in man also. The tissue invasion in man by maggots is generally a well-recognized complication of neglected wounds. The condition may be asymptomatic but occasionally results in more or less severe problems and even death when larvae invade body cavities or areas that forbid their direct visual examination. Many cases of myiasis, however, usually do not reach the attention of medical practitioners because of the tendency of the mature larvae to migrate out of the lesion for pupation. In the present study, the authors reviewed the past literature describing the cases of human myiasis, causative fly species and predisposing factors for the onset of the same. The aim of the present manuscript is to provide a database for the future reference of medical entomologists, medical practitioners and veterinarians. Review of literature revealed that 37 fly species belonging to ten families were responsible worldwide for the onset of human myiasis. The incidence of myiasis among humans can be correlated to increasing fly populations, poor hygienic conditions and presence of domestic animals in the close vicinity. Other factors responsible for myiasis include neglected open wounds and foul-smelling discharge from natural body openings. Moreover, ignorance plays a key role in its occurrence since people are generally unaware about the actual cause and often correlate the condition to their superstitious beliefs. It is emphasized that the patients should not neglect their wounds and should take proper medical care; otherwise, myiasis may supervene.

“…The robustness of the coxI gene as a diagnostic marker to lay the groundwork for identification of these three species of Sarcophaga has been demonstrated [ 21 , 26 ]. Sarcophaga argyrostoma has been identified using a coxI sequence in an elderly patient with an external ophthalmomyiasis (with 97% identity) [ 6 ] and very recently in a tracheotomized child's surgical wound (with an identity of 100%) [ 8 ]. In the present study, the involvement of S. argyrostoma in the wound myiasis is confirmed with 99% identity.…”

In Mediterranean countries, Sarcophaga (Liopygia) crassipalpis, Sarcophaga (L.) argyrostoma, and Sarcophaga (L.) cultellata share the same ecological niche and can be responsible of myiasis. In this study, the main morphological characters of a larva found in a hospitalized woman were described and illustrated by light and SEM microscopy and the features discussed. Then, a fragment within the mitochondrial encoded cytochrome c oxidase subunit I (coxI) gene of ~735 bp was amplified and sequenced. The molecular investigation was necessary to confirm the species Sarcophaga (Liopygia) argyrostoma (99% of identity). Our findings showed that morphological descriptions of larvae of three Mediterranean species of Liopygia available in several papers might not be clear enough to allow for comparison and correct identification. Until results of reliable comparative studies of larvae of all three species will be available, the use of molecular tools is crucial, to avoid misleading or incomplete identification, and in particular when a myiasis becomes a legal issue.
