Abstract

Complete mitochondrial genomes are reported for two Isospora species causing systemic coccidiosis in Superb Glossy Starlings (Aves: Sturnidae). The A/T rich (34.7% G/C) genomes were 6223 bp in length for Isospora greineri and 6217 bp for Isospora superbusi. Each encoded 3 protein-coding genes, (COI, COIII and CytB) plus 18 LSU and 14 SSU rDNA fragments. Arrangement of protein- and rRNA-coding regions was identical to known Eimeria sp. mt genomes; start codon usage was conventional. The mitochondrial genome structures of Isospora and Eimeria species are conserved and reflect the close phylogenetic association between these eimeriid genera of apicomplexan parasites.

Keywords: Coccidia; Isospora; atoxoplasmosis; fragmented rRNA; parasitology.

Phylogenetic tree based on the protein- and rRNA-coding regions of complete mitochondrial genome sequences from a variety of eimeriid coccidia demonstrates the close relationship between Isospora superbusi and Isospora greineri. The Bayesian analysis was performed on an alignment of 5394bp from each complete mitochondrial genome from the 3 CDS and 32 rDNA fragments; the dataset was partitioned so that the CDS were analyzed using a codon-based (mtmet translation) substitution model and the rDNA regions analyzed using a GTR + G + I substitution model. Scale bar indicates hypothesized evolutionary divergence and numbers at nodes indicate Bayesian posterior probabilities.
