Vírus rábico em morcego Nyctinomops laticaudatus na Cidade do Rio de Janeiro, RJ: isolamento, titulação e epidemiologia / Rabies virus in Nyctinomops laticaudatus bats in the City of Rio de Janeiro: isolation, titration and epidemiology

Apresenta-se o primeiro relato de raiva em morcego da espécie Nyctinomops laticaudatus, na Cidade do Rio de Janeiro, RJ. Foram realizados isolamento e titulação viral em diferentes tecidos, encontrando-se altos títulos no cérebro e glândulas salivares. A ocorrência de raiva em uma espécie pouco freqüente neste estado sugere que a doença pode ser mais prevalente do que aparenta.

The first case report of rabies in bats of the species Nyctinomops laticaudatus, in the city of Rio de Janeiro City, is presented. Virus isolation and titration were performed in different tissues, and high titers were found in the brain and salivary glands. Rabies occurrence in such an infrequent species in this state suggests that the disease may be more prevalent than it appears to be.

A method for testing the host specificity of ectoparasites: give them the opportunity to choose

Host-choice experiments were carried out with rodent and bat ectoparasites on Ilha Grande, state of Rio de Janeiro, Brazil. We constructed experimental chambers that enclosed three different rodent or bat host species, and then introduced a selected set of ectoparasitic arthropods. When given the opportunity to choose among host species, the ectoparasites showed a strong tendency to select their primary hosts, and reject novel host species. These kinds of simple experiments can be valuable tools for assessing the ability of ectoparasites to locate and discern differences between host species, and make choices about which hosts to infest, and which hosts to avoid.
