Abstract

Trypanosoma rangeli is a non-pathogenic hemoparasite, common in humans and other mammals. The epimastigotic forms of T. rangeli express an enzyme with sialidase (SA) activity, which is different from the trans-sialidase found in T. cruzi. Two subpopulations of T. rangeli have been described, one with sialidase activity (SA +) and the other without activity (SA-). The objective of this study was to analyze and compare the sequence of the T. rangeli SA gene in SA + and SA- isolates. For this purpose, 2 isolates were analyzed, one SA + from T. rangeli, and one SA-. Sialidase activity was measured using the MU-NANA technique. The total RNA and mRNA of each isolate was extracted, later the SA gene were cloned with pGEM-T Easy and sequenced with 3130 Genetic Analyzer Sanger. It was found that the isolates analyzed have 99% identity with a previously reported sialidase precursor gene, but at the same time it presented differences in 4 amino acid positions.
