Traumatic Myiasis of the Scalp in a 3-year-old Patient- A Case of Neglected Health Care

@#Traumatic myiasis, the invasion of live tissues by fly larvae, is a commonly observed phenomenon in animals like sheep and cattle, but is also witnessed sometimes among humans. It is a parasitic infestation in which the dipteran larvae invade the neglected open wounds and foul smelling body apertures of vertebrate animals thereby using the living or necrotic tissue of their host as a nutritional source. A case of severe human traumatic myiasis is reported from India in the scalp wound of a 3-year-old female patient. The causative larvae were identified as the third instars of Old World Screwworm Fly- Chrysomya bezziana (Diptera: Calliphoridae). The myiasis in the present case was a complication of an open neglected wound. Ignorance played a key role in non-treatment of the patient for a long period of time. The authors emphasize the necessity to raise awareness among the general public about the problem.

La miasis es una infestación por larvas en desarrollo de una gran variedad de moscas del orden Díptera. Según el sitio de invasión, se clasifica en miasis cavitarias, que pueden deberse a invasión de cavidades naturales o de heridas, y miasis forunculoide, cuando atraviesa piel indemne. Esta infestación presenta una distribución mundial, con variaciones estacionales en relación con la latitud geográfica y el ciclo de vida de distintas especies de moscas. Presentamos una serie de tres casos de pacientes con distintas formas clínicas de manifestación de miasis. (AU)

Myiasis is the tissue infestation by a variety of Diptera order larvae flies. According to the invasion site, they are classified in myiasis of cavities, which can be because of an invasion of natural cavities or wounds, and furuncular myiasis, when they invade through intact skin. This infestation has a worldwide distribution, with seasonal variations in relation to the geographic latitude and the life cycle of different species of flies. We present three cases of patients with different clinical forms of presentation of myiasis. (AU)

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

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.
