Myiasis*

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.

A 66-year-old male patient presented with rhinocnesmus and mild epistaxis. More than 100 maggots were found in the right nasal cavity by nasal endoscopy. The affected nasal mucosa was erythematous, edematous, ulcerated, and mild bleeding on probing was present. No nasal septal perforation or destruction of nose was noted. Middle and inferior meatus, nasopharyngeal mucosa, orbit, facial skin, oral cavity, gingiva and external auditory canal were normal. The maggot was identified as larvae of Chrysomyia megacephala.

Hypoderma spp. larvae cause subcutaneous myiasis in several animal species. The objective of the present investigation was to identify and characterize morphologically and molecularly the larvae of Hypoderma spp. collected from cattle (Bos taurus taurus) and red deer (Cervus elaphus) in the district of Castelo Branco, Portugal. For this purpose, a total of 8 larvae were collected from cattle (n=2) and red deer (n=6). After morphological identification of Hypoderma spp. larvae, molecular characterization was based on PCR-RFLP and mitochondrial CO1 gene sequence analysis. All larvae were morphologically characterized as the third instar larvae (L3) of H. actaeon. Two restriction enzymes were used for molecular identification of the larvae. TaqI restriction enzyme was not able to cut H. actaeon. However, MboII restriction enzyme differentiated Hypoderma species showing 210 and 450 bp bands in H. actaeon. Furthermore, according to the alignment of the mt-CO1 gene sequences of Hypoderma species and to PCR-RFLP findings, all the identified Hypoderma larvae were confirmed as H. actaeon. This is the first report of identification of Hypoderma spp. (Diptera; Oestridae) from cattle and red deer in Portugal, based on morphological and molecular analyses.
