DERMATITIS OUTBREAK CAUSED BY Dermanyssus gallinae, TRANSMITTED BY Zenaida melody "cuckoo pigeon"

Abstract

Three cases of dermatitis are reported causing a family outbreak, in patients who came to the Surquillo Health Center in Lima, with localized lesions in the neck, abdomen, chest and groin.The lesions presented were types of hives with itchy vesicles and an allergic-type reaction.The 3 patients were treated, observing in one of them erythematous papules with superficial crystalline vesicles and in the other two only an allergic dermatitis-type reaction with manifestations of urticaria and intense pruritus was observed.What helped in the diagnosis is that those affected gave us a gummed tape with some specimens that they were able to capture, which were identified as nymphs and adults of Dermanyssus gallinae (Arachnida: Acari: Dermanyssidae) De Geer, 1778.They also took photos of the pigeons involved in being carriers of the ectoparasites, which were identified as Zenaida meloda "melody pigeon or cuckoo pigeon.Records of human infestations by bird mites occur during nesting seasons, when young birds leave their nests, when humans handle infested nests, or when the dispersal of the mites occurs by some means of access to the interior of the dwellings.
