摘要
A total of 1,921 expressed sequence tags (ESTs) were obtained from bloodstream trypomastigotes of Trypanosoma carassii, a parasite of economic importance due to its high prevalence in fish farms. Analysis of the data set allowed us to identify a trans-sialidase (TS)-like gene and three ESTs coding for putative mucin-like genes. TS activity was detected in cell extracts of bloodstream trypomastigotes. We have also used the sequence information obtained to identify genes that have not been previously described in trypanosomatids. (Additional information on these ESTs can be found at http://genoma.unsam.edu.ar/projects/tca.).
