The spliced leader RNA genes of Bodo saltans, Cryptobia helicis and Dimastigella trypaniformis were analyzed as molecular markers for additional taxa within the suborder Bodonina. The non-transcribed spacer regions were distinctive for each organism, and 5S rRNA genes were present in Bodo and Dimastigella but not in C. helicis. Two sequence classes of 5S rRNA were evident from analysis of the bodonid genes. The two classes of 5S rRNA genes were found in other Kinetoplastids independent of co-localization with the spliced leader RNA gene.

“…The nuclear multicopy spliced leader (SL) RNA gene, also known as the mini-exon gene, has been used as a genetic marker to distinguish and/or characterize different protozoan species within the suborder Trypanosomatina, such as Trypanosoma sp. (Tibayrenc et al 1993 ;Murthy, Dibbern & Campbell, 1992 ;Grisard, Campbell & Romanha, 1999 ;Souto et al 1996 ;Fernandes et al 1998 ;Sturm et al 1998), Crithidia sp.

A new species of trypanosome, Trypanosoma desterrensis sp. n., isolated from South American bats

Trypanosomes isolated from South American bats include the human pathogen Trypanosoma cruzi. Other Trypanosoma spp. that have been found exclusively in bats are not well characterized at the DNA sequence level and we have therefore used the SL RNA gene to differentiate and characterize kinetoplastids isolated from bats in South America. A Trypanosoma sp. isolated from hats in southern Brazil was compared with the geographically diverse isolates T. cruzi marinkellei, T. vespertilionis, and T. dionisii. Analysis of the SL RNA gene repeats revealed size and sequence variability among these bat trypanosomes. We have developed hybridization probes to separate these bat isolates and have analysed the DNA sequence data to estimate their relatedness. A new species, Trypanosoma desterrensis sp. n., is proposed, for which a 5S rRNA gene was also found within the SL RNA repeat.
