Notas sôbre a evolução do virus vacínico em animais silvestres da fauna brasileira

Abstract

<abstract language="eng">A note on the evolution of cow-pox virus in wild animals of Brazilian fauna. We have tried the sensibility of wild animals of Brazilian fauna to the cow-pox virus. The following specimens were submitted to experiences: Procyon cancrivorus, Hydrochoerus capybara, Cavea aperea, Coendu villosus, Didelphis aurita, Bradypus tridactylus, Euphractus sexcintus, Tamandua tetradactylus, Nasua narica, Dasyprocta aguti and Testudo tabulata. In all these animals, - excepting Bradypus tridactylus - we have obtained an infection with incubation (five days), aspect and duration similar to cow-pox of the laboratorial animals (calf and rabbit). In the Bradypus tridactylus howewer, the incubation was very long. Only after 30 days of inoculation we verified the infection with the formation of vesiculae and postulae

Tamandua tetradactyla (Pilosa: Myrmecophagidae)

“…T. tetradactyla can be experimentally infected with Schistosoma mansoni (Barbosa et al 1958). The species is susceptible to infection by the cowpox virus after 5 days of incubation (Moreira 1956).…”

Single Stranded DNA Viruses Associated with Capybara Faeces Sampled in Brazil

“…Vaccinia virus (VACV) (family Poxviridae ) has been identified in faeces of capybaras from wild and urban areas of Brazil [8] and has also been detected in serum samples by serological assays [9]. A study with experimentally infected capybaras demonstrated that VACV is able to replicate in this rodent species [10], supporting their role in the ecology of VACV [11]. Serological assays have shown the presence of Rabies virus (family Rhabdovirus ), which is believed to be transmitted to the capybaras by blood-feeding bats [12].…”
