Bilateral aural myiasis (Wohlfahrtia magnifica): a case with chronic suppurative otitis media.
(1/18)
Myiasis is a disease caused by fly larvae and aural myiasis is a rare clinic condition often occuring in children or mentally retarded people. We report the case of an unusual presentation of a bilateral aural myiasis in a mentally retarded patient with bilateral chronic otitis media caused by the third instar larvae of Wohlfahrtia magnifica. Two larvae were located on the other ear canal while two additional larvae were located in the middle ear cavity and were removed through perforation of the tympanic membrane. Treatment of aural myiasis is based on removal of the maggots and cleansing of the ear with ethanol, chloroform or physiological saline. Physiological saline is preferred in patients who have tympanic membrane perforation. Myiasis is related to personal hygiene. Therefore, in order to decrease the incidence of these infestations, care and hygiene standards should be carried out for those at risk. (+info)
Ignatzschineria indica sp. nov. and Ignatzschineria ureiclastica sp. nov., isolated from adult flesh flies (Diptera: Sarcophagidae).

Aural myiasis is a rare clinical state that usually occurs in developing countries and in patients who mentally retarded or have poor personal hygiene. However, the prevalence has decreased over the years, and now it is very rare. The authors describe a case of aural myiasis caused by Wohlfartia magnifica in a five-month-old infant. The treatment used was a combination of suctioning and microsurgical forceps under an operative microscope. Additionally, topical and oral antibiotics were given to avoid secondary infection. (+info)
A new record of Iranihindia martellata (Senior-White,1924) (Diptera: Sarcophagidae) from peninsular Malaysia and female identification using both morphology and DNA-based approaches.
(5/18)
Iranihindia martellata (Senior-White, 1924) is recorded from peninsular Malaysia for the first time. Male and female specimens in the recent collections of forensically important sarcophagid flies were examined and identified based on morphology and DNA sequencing analysis. Male genitalia offer unambiguous species identification characteristics in the traditional taxonomy of flesh flies but the female flies are very similar to one another in general morphology. Female of I. martellata was determined by DNA sequencing (COI and COII) and PCR-RFLP (COI) analysis. Identified females were carefully examined and compared with the morphologically similar species, Liopygia ruficornis (Fabricius, 1794). Female genitalia are re-described and illustrated in this paper. (+info)
Molecules participating in insect immunity of Sarcophaga peregrina.
(6/18)
Pricking the body wall of Sarcophaga peregrina (flesh fly) larvae with a needle activated the immune system of this insect and induced various immune molecules, including antibacterial proteins, in the hemolymph. In this review, I summarize and discuss the functions of these immune molecules, with particular emphasis on the dual roles of some of these molecules in defense and development. (+info)
Identification of the forensically important sarcophagid flies Boerttcherisca peregrina, Parasarcophaga albiceps and Parasarcophaga dux (Diptera: Sarcophagidae) based on COII gene in China.
(7/18)
Accurate species identication is a crucial step in forensic entomology, as the insect collected on a corpse can provide useful information for estimation of postmortem interval (PMI). The utility of the forensically important Sarcophagidae (Diptera) for crime scene investigation has been severely restricted, as morphological identification is difficult, especially the identification of females and larvae. In this study, a method for using mitochondrial DNA (mtDNA) sequence data and phylogenetic analysis was performed to distinguish the three Chinese sarcophagid species: Boerttcherisca peregrina (Robineau-Desvoidy, 1830) Parasarcophaga albiceps (Meigen, 1826) and Parasarcophaga dux (Thompson, 1869) (Diptera: Sarcophagidae). DNA was extracted and analyzed by a 189 bp fragment of cytochrome coxidase subunit II (COII) gene. The monophyletic branches of the phylogenetic tree reveal that this marker is suitable for discrimination between these species, providing high support for separation on congeneric species. Therefore, the molecular method applied to the sarcophagid species identification is feasible. (+info)
