Abstract: Como parte de um inquérito sorológico pesquisando anticorpos para arbovírus, em habitantes da região de Ribeirão Preto, 202 soros foram testados por neutralização em camundongos, para o vírus Piry. Trata-se de um vesículo-vírus (Rhabdoviridae) isolado em Belém do Pará, das vísceras de um marsupial e do sangue de um caso humano. O Piry é causa de doença humana aguda febril. Desconhece-se seus reservatórios animais, vetores e seu ciclo biológico. Os 202 soros testados foram obtidos por venopunção, de moradores a… Show more

“…The serosurveys studies performed in several places of Brazil have shown neutralising antibodies to PIRYV in more than 10% of the participants. Based on an accidental infection in the laboratory, we know that PIRYV produces an acute febrile illness ( Pinheiro et al 1974 , Figueiredo et al 1985 , Tavares-Neto et al 1990, Souza et al, in press). In contrast, we have tested 410 sera of patients with acute febrile illness by the real-time RT-PCR for VSV, but all samples were negative for VSV.…”

“…However, serological studies have reported a high prevalence (4-17.7%) of specific Piry vesiculovirus (PIRYV) neutralising antibodies in populations from different regions of Brazil ( Pinheiro et al 1974 , Figueiredo et al 1985 , Tavares-Neto et al 1990). In addition, human disease was reported in five cases, all related to laboratory accidents, with typical acute infectious viral disease ( Pinheiro et al 1974 , Figueiredo et al 1985 , Souza et al, in press). In the 1960‘, PIRYV, Cocal and Maraba virus were isolated in Brazil from opossum ( Philander opossum ), mites ( Gigantolaelaps sp ) and sand flies ( Lutzomyia sp ), respectively.…”

“…Carajás and Marabá virus and specially Piry virus are also common causatives of human infection in Brazil. Serologic surveys carried out in Northeastern and Southeastern inland towns in Brazil showed that 16 and 14.3% of the participants had neutralizing antibodies to Piry virus, respectively (Figueiredo et al 1985). Knowing that Piry infections are common and that Piry fever is probably under reported because only 3 human cases were described, this RT-PCR could be used for diagnosis of infections by this virus in Brazilian patients having acute febrile illness.…”
