Chagas Immunochromatographic Rapid Test in the Serological Diagnosis of Infection in Wild and Domestic Canids.

(domestic dog) represents a reliable sentinel for the occurrence of a well-established transmission cycle of among wild mammals in the surroundings and, consequently, where the risk of human infection exists. Serological diagnosis is the chosen method to identify infection in dogs that, in Brazil, rarely present positive parasitological tests. The use of recombinant chimeric parasitic antigens results in a sensitive and specific serological diagnostic test in contrast to the use of crude antigens.

[Rabies virus in Nyctinomops laticaudatus bats in the City of Rio de Janeiro: isolation, titration and epidemiology].

The first case report of rabies in bats of the species Nyctinomops laticaudatus, in the city of Rio de Janeiro City, is presented.
