In this paper, we present transcriptome data for Balantidium ctenopharyngodoni Chen, 1955 collected from the hindgut of grass carp (Ctenopharyngodon idella). We evaluated sequence quality and de novo assembled a preliminary transcriptome, including 43.3 megabits and 119,141 transcripts. Then we obtained a final transcriptome, including 17.7 megabits and 35,560 transcripts, by removing contaminative and redundant sequences. Phylogenomic analysis based on a supermatrix with 132 genes comprising 53,873 amino acid residues and phylogenetic analysis based on SSU rDNA of 27 species were carried out herein to reveal the evolutionary relationships among six ciliate groups: Colpodea, Oligohymenophorea, Litostomatea, Spirotrichea, Heterotrichea and Protocruziida. The topologies of both phylogenomic and phylogenetic trees are discussed in this paper. In addition, our results suggest that single-cell sequencing is a sound method of obtaining sufficient omics data for phylogenomic analysis, which is a good choice for uncultivable ciliates. The transcriptome data for Balantidium ctenopharyngodoni are the first omics data within the subclass Trichostomatia, and provide a good basis for ciliate phylogenomic analysis, as well as related omics analysis.
