Abstract

Each year the trafficking of wild animals is responsible for the removal of approximately 38 million individuals from the Brazilian fauna. (RENCTAS, 2001). However, the proportion of individuals that survive the conditions of the traffic is significantly reduced against the initial number, since the losses that occur throughout the process of capturing and marketing, particularly given the precarious conditions in which the animals are subjected. Among the most targeted mammals by the trafficking highlight the primates, with emphasis on New World species, of which 95% originate from the Brazilian territory (RENCTAS, 2001). Proving this fact, it brings up that animals of the genus Callithrix occupy the second position in the list of most seized mammals by the Wildlife Screening Centers of the Brazilian Institute of Environment and Renewable Resources. (BARINO, 2008). As a result of the illegal trafficking of these animals, many of them presents classical symptoms of dehydration, malnutrition, as well as injuries and trauma. In addition, another serious consequence of illegal trade is the lack of sanitary control of these animals that can transmit serious diseases to domestic creations and even for humans. For these reasons, there is a need to establish indicators, still little-known, to the proper sanity evaluation of primates from the trade, as well as for monitoring, recovery and reintroduction of these individuals. This work aims to establish hematological, glycemic and parasitological indicators of a white-tufted-marmoset (Callithrix jacchus) and black-tufted-marmoset (Callithrix penicilatta) populations from a breeding of the State of São Paulo, as well as establish possible relationships between these parameters and possible changes related to diseases, for the purpose of contribute with data that can be useful in the health evaluation of confiscated marmosets.
