ABSTRACT
Abstract: We herein report human dermatitis caused by the tropical fowl mite Ornithonyssus bursa (Berlese). The cases occurred in an apartment in a residential district of Porto Alegre City, State of Rio Grande do Sul, Brazil, where three members of the same family presented with pruritic lesions on the arms and legs. On inspecting the bathroom, several mites measuring approximately 1.0mm in length were observed coming from a nest of Rufous Hornero, Furnarius rufus (Gmelin). This is the first report of O. bursa in the urban area of Porto Alegre City, from a nest of F. rufus that bites humans.

O Núcleo de Reabilitação da Fauna Silvestre e Centro de Triagem de Animais Silvestres da Universidade Federal de Pelotas - RS atendeu dois filhotes de Megascops choliba (corujinha-do-mato) (Strigiformes - Strigidae) e dois de Pitangus sulphuratus (bem-te-vi) (Passeriformes - Tyrannidae) intensamente parasitados por ácaros, em maio de 2005 e dezembro de 2006, respectivamente. Os filhotes e o ninho de P. sulphuratus foram recolhidos na zona urbana da cidade de Pelotas - RS após forte temporal. Os ácaros foram removidos, colocados em álcool 70 por cento e levados ao laboratório de parasitologia para identificação. Os espécimes foram clarificados em lactofenol, montados em meio de Hoyer e identificados como Ornithonyssus bursa (Acari - Macronyssidae). Registra-se Megascops choliba e Pitangus sulphuratus como hospedeiros de Ornithonyssus bursa, no Rio Grande do Sul, Brasil.
The Center for Rehabilitation of Wildlife and Center for Selection of Wild Animal of the Federal University of Pelotas has attended two nestlings of Megascops choliba (tropical screech-owl) (Strigiformes - Strigidae) and two of Pitangus sulphuratus (great kiskadee) (Passeriformes - Tyrannidae) heavily parasitized by mites, in May 2005 and December 2006, respectively. The nestlings and the nest of P. sulphuratus were collected in the Pelotas urban area after severe storms. The mites were removed, clarified in lactofenol, permanently mounted in Hoyer's medium and identified as Ornithonyssus bursa (Acari - Macronyssidae). Megascops choliba and Pitangus sulphuratus are reported as host of Ornithonyssus bursa in Rio Grande do Sul State, Brazil.
