Nasal Myiasis

Infection by the larval form of Oestrus ovis (sheep bot fly) is common in many areas of Peru. This is an obligate parasite of sheep and goats, and it is the cause of oestrosis, or nasal myiasis, which can lead to severe clinical manifestations in livestock. A case of myiasis caused byO. ovis in a llama (Lama glama) in Cuzco, Peru, is reported here. This llama presented with respiratory distress and died due to bilateral hemorrhagic pneumonia. During the necropsy, six intact dipterous larvae were recovered from the nasal fossae and cranial sinuses being identified as O. ovis. This is the first report of nasal myiasis in llamas due to O. ovis in Peru.

Nasal Myiasis

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 byOestrus ovisin a 56-year-old man from Cusco in Peru. He presented with nasal pruritus, congestion, and sneezing white “cottony” material. The material was identified asO. ovislarvae. A literature review of publications reporting nasal myiasis caused byO. ovisis presented.

Nasal Myiasis

Abstract: First larval stage (L1) of Oestrus ovis was recovered by flushing of the nasal cavity during rhinoscopy in an urban living dog. The dog was taken to the Small animal clinic after an acute onset of sneezing and bilateral nasal discharge. In Europe, there are sporadic reports of nasal myiasis in dogs caused by sheep bot flies, and the overall prevalence of O. ovis is high in Mediterranean countries. Because of its habitat expansion due to climate change, it should be considered as a differential diagnosis when an animal patient presents with signs of rhinitis in areas bordering the Mediterranean climate. This is the first report of a dog infested by sheep nasal bot fly in Slovenia.Key words: Oestrus ovis; sheep bot fly; nasal myiasis; dog; climate changesPRVI PRIMER PASJE MIAZE Z OVČJIM NOSNIM ZOLJEM, Oestrus ovis, V SLOVENIJIIzvleček: Med rinoskopijo in spiranjem nosne votline, smo pri psu, ki živi v urbanem okolju, ugotovili ličinke prve stopnje (L1) zajedavca Oestrus ovis. Lastniki so psa pripeljali na Kliniko za male živali po akutnem izbruhu kihanja in bilateralnega nosnega izcedka. V Evropi so dokumentirani sporadični primeri nosne miaze pri psih zaradi ovčjega nosnega zolja, O. ovis, in skupna prevalenca ovčjega zajedavca je v mediteranskih državah visoka. Zaradi klimatskih sprememb, se habitat nosnih zoljev čedalje bolj širi, za kar je pomembno O. ovis vključiti v seznam diferencialnih diagnoz pri pacientih s kliničnimi znaki rinitisa tudi na področjih, ki mejijo na mediteransko klimo. To je prvi opisan primer infestacije psa z ovčjim nosnim zoljem v Sloveniji.Ključne besede: Oestrus ovis; ovčja nosni zolj; nosna miaza; pes; podnebne spremembe

AbstractObjective:We report a case of an Oestrus ovis larva which developed into the second larval stage within a healthy, immunocompetent human, and we review the relevant literature.Methods:Clinical case report and Pubmed search of reports of human nasal myiasis due to Oestrus ovis, especially those describing the larval stage.Results:Humans are not normally hosts of the sheep nasal bot fly, but infestations by its larvae have been described. The eye is the most common site, but larvae have occasionally been found in the human nose. Transformation of larvae into the second and third stages, within the human nose, is even more uncommon.Conclusion:To the best of our knowledge, we report the first Swedish case, and the third case world-wide, of Oestrus ovis larval development beyond the first larval stage, within an immunocompetent, healthy human.

Nasal Myiasis

A companion dog from Milan province (northern Italy), presenting with frequent and violent sneezing, underwent rhinoscopy, laryngoscopy, and tracheoscopy procedures. During rhinoscopy, a dipteran larva was isolated from the dog and identified as first instar larval stage ofO. ovisby morphological features. Reports ofO. ovisin domestic carnivores are sporadic and nevertheless this infestion should be considered as a possible differential diagnosis of rhinitis in domestic carnivores living in contaminated areas by the fly as consequence of the presence of sheep and goats. This report described a case of autochthonous infestion in a dog from an area whereO. oviswas not historically present but it could be affected by a possible expansion of the fly as a consequence of climate change. This is the first record ofOestrus ovisinfestion in a dog in Italy and, at the same time, the most northerly finding of larvae of sheep bot fly in the country.
