“…Like in our patient, the nasal infestation is characterized by local inflammation of the mucosa and sneezing with spontaneous elimination of the larvae usually without leaving sequelae. All oestrid flies are host specific and only rarely infect accidental hosts [8]. The flies are larviparous and deposit their living offspring directly into or near the eyes and nose of sheep, their primary host [8].…”

“…All oestrid flies are host specific and only rarely infect accidental hosts [8]. The flies are larviparous and deposit their living offspring directly into or near the eyes and nose of sheep, their primary host [8]. The first instar (L1) larvae travel up into the nasal sinuses of their host and continue their maturation to the third instar (L3) stage.…”

“…Cavitary myiasis caused by O. ovis is rare in humans. However, in some countries, like Libya, the annual incidence of cavitary infestation may reach 1/10,000 among humans [8]. Other less common presentations of O. ovis can involve the oral cavity, pharynx, and tonsils.…”

Myiasis is the infestation by dipterous larvae. The larvae can infect intact or decaying tissue including the skin or epithelial surfaces of the orbits, nose, and genitourinary and gastrointestinal tracts. We report a case of primary obligatory nasal myiasis by Oestrus ovis in a 56-year-old man from Cusco in Peru. He presented with nasal pruritus, congestion, and sneezing white “cottony” material. The material was identified as O. ovis larvae. A literature review of publications reporting nasal myiasis caused by O. ovis is presented.

“…A frequência de infestação dos caprinos foi baixa 8,33% (2/24). Este achado pode estar relacionado a habilidade de defesa dos caprinos em evitar o contato com a mosca, uma menor umidade na cavidade nasal em relação aos ovinos e um sistema imune com maior adaptação a infestação, sugerindo que os caprinos co-evoluíram com o O. ovis (Dorchies et al 1998, Angulo-Valadez et al 2010. A temperatura tem uma relação direta com a atividade da mosca, já que existe uma predileção de horários mais quentes para larviposição (Cepeda-Palacios & Scholl 2000).…”

Resumo: No período de janeiro de 2011 a dezembro de 2014 foram diagnosticados 9 surtos (A, B, C, D, E, F, G, H e I) de Oestrus ovis em pequenos ruminantes no estado da Bahia. No surto A obteve-se 0,5% (1/200); B 2,2% (2/90); C 0,8% (1/120); D 2% (2/100); E 1% (1/100); F 3% (1/33); G 0,6% (1/150); H 2,5% (5/200); I com 11,4% (8/70) em ovinos e 5% (2/40) em caprinos. Os sinais clínicos associados ao parasitismo pelas larvas nos surtos foram respiração ruidosa, espirro seguido de secreção nasal catarral, inquietação, movimentação excessiva da cabeça e andar em círculo. Macroscopicamente havia nos seios e conchas nasais hiperemia, edema da mucosa e presença de larvas. Todas as larvas coletadas dos cornetos e conchas nasais variavam desde o primeiro ao terceiro estágio de desenvolvimento. Algumas larvas L3 coletadas nas necropsias foram incubadas e o imago obtido das pupas mediram aproximadamente 10mm de cor acinzentada e abdômen escurecido. Realizada análise descritiva das condições climáticas, ano e positividade de casos de oestrose, demonstrou que a ocorrência tem tendência de crescimento com os anos (p˂0,001) e que houve casos com menor média de temperatura mínima (p˂0,001), possibilitando o desenvolvimento da mosca de O. ovis, demonstrando que houve a introdução da mosca enTtre o rebanho de ovinos e caprinos do estado da Bahia, e que as condições climáticas são ideais para perpetuação da espécie.

“…[8] Myiasis cases involving various other organs, with different underlying conditions are reported in children. [91112131415] It is now clear that gastrointestinal infestation of children with fly larvae is not uncommon. Reports have highlighted the increased prevalence of human myiasis in rural population as compared to the urban counterparts, which may be attributed to different domestic activities including agriculture.…”

The occurrence of dipterous fly larvae in human is termed as human myiasis. Human myiasis can be classified based on clinical condition it causes like cutaneous myiasis, ocular myiasis, urogenital myiasis and intestinal myiasis. Based on the need for a particular host, myiasis can be divided as specific myiasis, semi-specific myiasis. Accidental myiasis results when the fly larvae are deposited/ingested by human resulting in infestation, which is also called as pseudomyiasis. Fly larvae may be present on the dead and decaying organic matter and domestic animals like dog and cats which are naturally infested with fly larvae and can be source for infection in children. Very few cases have been retrieved from literature on the occurrence of intestinal myiasis in children throughout the world. We report a case of two siblings in the same family infested with dipterous fly larvae.
