Abstract

TORRICO, M.C. et al. Trypanosomatidae isolated from wild mammals in three departments of Bolivia (Cochabamba, Potosi and Santa Cruz de la Sierra). Gac Med Bol [online]. 2013, vol.36, n.1, pp.6-10. ISSN 1012-2966.

Objectives: The aim of this research was isolate kinetoplastid protozoan from wild mammals in three departments of Bolivia, to identify Trypanosomatids reservoirs that could cause infection in different reservoirs and disease in humans. Methods: The wild mammals were caught in the Chaco, valleys and the tropical zone of Bolivia, using Sherman, Havahard and Tomahawk traps. Captured animals were anesthetized and xenodiagnosis and blood cardiac puncture was performed; trypanosomatides isolation using blood culture was done in NNN culture media and the respective identification was performed by PCR-RFLP techniques in the molecular biology laboratory of IIBISMED. Results: 236 wild mammals belonging to 30 species were captured, of which 7 species showed infection by hemoflagellates. Trypanosoma cruzi was isolated from Didelphis marsupialis, D. albiventris, Galea musteloides, Graomys domorum and Andalgalomis pearsoni; T.c. marinkellei and T. dionisii were isolated from Carolia perspicillata (bats) and other kinetoplastid not identified by available molecular tools were also isolated from Andalgalomys and Graomys mammals genus, from Campero and Cordillera provinces of Cochabamba and Santa Cruz. Conclusions: The T. cruzi, T.c. marinkellei, T. dionisii and other trypanosomatids are infecting marsupials (Didelphis), rodents (Graomys and Andalgalomys) and wild guinea pigs (Galea) which are found in a sylvatic cycle in the studied areas.
