“…Recently, a case of human ophthalmomyiasis caused by the larva of Phormia sp. had been recorded in an enucleated patient (Kim et al 2011). Blow flies are usually the first insects to settle in a body, frequently within minutes after death (Catts and Goff 1992).…”

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

et al. 2015

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.

“…Phormia sp. was found to be the causative agent from Korea by Kim et al (2011). L. sericata, the green bottle fly, was also found to be associated with external ophthalmomyiasis in various cases (Misra et al 2013;Kalezic et al 2014;Choi et al 2015).…”

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.

“…Even if adult flies are successfully recovered, species-level identification is very difficult without taxonomic knowledge [20]. As a consequence, several human myiasis cases have been reported in Korea without detailed species identification, or with identification only to the genus level [5,8,10,12,13]. To solve this problem, forensic entomologists introduced DNA-based identification, a method that allows easy identification of dipterans even if specimens are immature or dead [20].…”

“…These results provided sufficient evidence to regard our specimens as L. sericata . Additionally, our skin-offed techniques could be useful when the number of specimens available for identification is either small or limited to only 1 individual [10]. …”

Canine Wound Myiasis Caused by Lucilia sericata (Diptera: Calliphoridae) in Korea

et al. 2016

Myiasis is a relatively common infection of animals kept as pets, although only 1 case of canine myiasis has been described so far in the Republic of Korea. In the present study, we report an additional case of canine wound myiasis with identification of its causative agent, Lucilia sericata. An 8-year-old male Siberian husky dog was referred with anorexia, vomiting, and diarrhea to the Chungbuk National University Veterinary Medical Center, Cheongju-si (city), Chungcheongbuk-do (province), Korea in July 2013. Physical examination indicated the patient had a deep wound filled with a maggot swarm as a left gluteal lesion. A total of 216 maggots were removed by forceps, and the wounded area was sponged with gauzes and disinfected with 70% alcohol and a povidone-iodine solution. After daily care and suturing the wound, the patient was discharged at day 19 after admission. Recovered worms possessed morphological characteristics similar to those of L. sericata, namely, a sub-cylindrical body with 6–8 lobed anterior spiracles, round shaped with a button surrounded by a peritremal ring with no gaps, and similar distances between dorsal, median, and outer papillae of the 12th segment. Additionally, cox1 partial sequences (528 bp) obtained in the present study showed 100% identity with those of L. sericata (GenBank no. KT272854.1). L. sericata is indicated as a pathogen of myiasis infection not only in humans, but also in animals kept as pets in Korea.
