    Abstract:
    BACKGROUND: Communicating the presence of potential zoonotic pathogens such as Plasmodium spp. in wild animals is important for developing both animal and human health policies. METHODS: The translocation of an exotic and invasive population of Leontopithecus chrysomelas (golden-headed lion tamarins) required the screening of these animals for specific pathogens. This studies objective was to investigate Plasmodium spp. infection in the L. chrysomelas, both to know its prevalence in these animals in the local area and to minimize the risk of pathogens being translocated to the destination site. To investigate Plasmodium spp. infection, blood samples from 268 animals were assessed for the presence of Plasmodium spp. by genus-specific PCR and stained thick and thin blood smears were examined by light microscopy. Data of human malaria infection in the studied region was also assembled from SINAN (Diseases Information System Notification-Ministry of Health of Brazil). RESULTS: Results from the PCR and microscopy were all negative and suggested that no L. chrysomelas was infected with Plasmodium spp. Analysis of SINAN data showed that malaria transmission is present among the human population in the studied region. CONCLUSIONS: This study is the first to provide information on Plasmodium spp. infection in L. chrysomelas. Plasmodium spp. infection of this species is rare or absent though malaria parasites circulate in the region. In addition, there is minimal risk of translocating Plasmodium spp. infected animals to the destination site.
