This page contains details of a partial trypanosomatid genomic sequence from an unnamed species of Crithidia. This organism is a parasite of insects and was originally recorded as Crithidia deanei. As a close relative of the human parasites Leishmania spp. and Trypanosoma spp., it should provide useful comparisons with those genome sequences.

Data Downloads

This project was formerly described as belonging to Crithidia deanei. In 2009, Yurchenko et al. (Int J Syst Evol Microbiol, 59:893-909) showed that the C. deanei ATCC30255 isolate was incorrectly named since the cells did not contain the b-proteobacterial endosymbionts characteristic of C. deanei and its close relatives, and was phylogenetically related to Crithidia insperata and Leptomonas bifurcata. Therefore, the project has been renamed and this species is likely to belong to a Crithidia or Leptomonas species near to Leishmania. The data are unchanged.

Published Genome Data

A fosmid library was created for this Crithidia sp. genome (ATCC 30255) in 2007 with average insert size of 25kb and approximately 4x clone coverage. End-sequencing of all fosmids in the library has produced an initial library of 10,092 sequence reads, which may be searched here. In addition to the end-sequences, various fosmids have been fully sequenced, producing 10,363 further reads that are included here. Users should beware of possible contamination from vector or vector host material during the cloning process.

Data Use Statement

This sequencing centre plans on publishing the completed and annotated sequences in a peer-reviewed journal as soon as possible. Permission of the principal investigator should be obtained before publishing analyses of the sequence/open reading frames/genes on a chromosome or genome scale. See our data sharing policy.
