Oral myiasis is a rare manifestation in humans and is vulnerable to attack in conditions leading to persistent mouth opening along with poor oral hygiene, suppurating lesions and cancerous wound, mainly in tropical countries. Myiasis is diagnosed clinically based on the presence of maggots and traditional management is the mechanical removal of the larvae. This is a case report of myiasis in a 44-year-old man diagnosed with invasive oral squamous cell carcinoma. The treatment consisted of manual removal of the larvae and cleaning with aqueous chlorhexidin 0.12%. The patient's management was antisepsis, larval removal and general care, performed weekly. The patient died 2 months later. The management of patients by healthcare service and hygiene orientations is recommended to prevent oral myiasis infestation, mainly in patients living in fly breeding habitats and who do not comply with basic oral hygiene measures, which may be make individuals more prone to develop myiasis.

Myiasis is a parasitic infestation of soft vertebrate tissues by larval stages of Diptera. We briefly described the lesion-causing genus Cordylobia Grünberg (Diptera: Calliphoridae). Three Polish travelers to Uganda, Gambia, and Senegal returned with furuncular myiasis.

The infestation of ruminants by fly larvae of the Oestridae family can lead to nasopharyngeal or subcutaneous myiasis, which can harm animal welfare and productivity on sheep and cattle farms. The infestation of wild ruminants allows them to serve as reservoirs for subsequent transfer to domestic animals. The fly species most commonly responsible for myiasis have been well studied in many parts of the world, but less so in southeastern Europe.

Background: In this study, we investigated the genetic variability and population structure of the New World screwworm fly Cochliomyia hominivorax. We tested the hypothesis that the species exhibits a center-periphery distribution of genetic variability, with higher genetic diversity in central populations (e.g.

Parasitism, a widespread nutrient acquisition strategy among animals, results from a long evolutionary history where one species derives its metabolic needs from another. Parasites can significantly reduce host fitness, affecting reproduction, growth, and survivability. Vertebrate hosts exhibit defensive strategies against parasites, including "sickness behaviors" such as lethargy and self-grooming to remove ectoparasites.

A 70-year-old woman with a 6-month history of poor hygiene presented with a right occipital mass, ulceration, and neck swelling. The right occipital region was infested with approximately 100 fly maggots, and the mass contained a foul-smelling abscess. Maggots were removed, and the mass was drained, irrigated, and dressed with padding.
