The present study describes the first report of Trypanosoma vegrandis in koalas using morphology and sequence analysis of the 18S rRNA gene. The prevalence of T. vegrandis in koalas was 13.6% (6/44). It is likely that the small size of T. vegrandis (< 10 μm in length), coupled with the difficulties in amplifying DNA of this parasite in mixed infections using trypanosome generic primers, are the reason why this organism has not been identified in koalas until now. This study highlights the importance of further research comprising a larger sample size to determine the prevalence of T. vegrandis in koalas as well as its potential impacts upon this marsupial species' health.
