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.

With the purpose of verify the presence of larvae from the genus Gasterophilus in the Rio Grande do Sul State, a study was undertaken using 395 horses taken to slaughter in the city of Pelotas. The material analysis revealed that 126 animals (31,90 percent) presented infection, with 100 animals (25, infected by Gasterophilus nasalis, and 47 animals (11,90 percent) infected by G intestinalis. These results also represent the first report of the definite establishment of G intestinalis as a horse parasite in Brazil. The probable implications of G. intestinalis occurrence in Brazil are discussed.
Com o objetivo de verificar a presença de larvas do gênero Gasterophilus no Estado do Rio Grande do Sul, foi realizado um estudo com 395 equinos sacrificados em um abatedouro da cidade de Pelotas. O material analisado revelou que 126 animáis (31,90 por cento) apresentaram a infecção, sendo que 100 animáis (25,32 por cento) estavam infectados por Gasterophilus nasalis e 47 (11,90 por cento) por G intestinalis. Estes resultados também representan o primeiro relato definitivo de estabelecimento de G. intestinalis como parásito de equinos no Brasil. As implicações prováveis da presença de G. intestinalis no Brasil são discutidas.
