Abstract

In October 2010 in the Guayaramerin region, Beni-Bolivia, thick smears were observed and it was detected the presence of flagellar forms compatible with Trypanosoma cruzi. The Laboratory of Parasitology, INLASA by direct tests (smear, thick smear and micromethod variety INLASA) and indirect tests confirmed the presence of Trypanosoma cruzi in 14 samples. In the epidemiological monitoring it was determined that all cases got infected by oral transmission, through the consumption of a juice of Majo fruit that came from the Amazon region of Guayaramerin-Beni. The monitoring carried out in all cases showed that the onset of infection presented high parasitemia, fever, lymphocytosis, elevated transaminases corresponding to a characteristic clinical profile of acute infection by Trypanosoma cruzi. the isolation of the parasites were done using in vitro culture for identification of the species of Trypanosoma cruzi present.
