Abstract
The 6313 bp complete mitochondrial (mt) genome of Caryospora bigenetica was sequenced directly from PCR products. The mt genome was comparable in size, gene content and order to those of other Eimeriid coccidia (e.g. Isospora or Eimeria species). Three protein-coding genes encoding COI, COIII and CytB were identified; numerous rDNA fragments (19 LSU and 14 SSU) were interspersed among the CDS. Nucleotide composition was A + T biased (66%). The mitochondrial genomes of Eimeriid coccidia appear to share the same gene order and content; mt genome sequences can provide molecular data useful for diagnostics, taxonomy and phylogenetic relationships of Eimeriid coccidia.
