Abstract

The genus term Isospora is now applied specifically to parasites of birds, with the term Cystoisospora preferred for parasites which infect mammals. Isospora is a common parasitic coccidian in birds worldwide, especially in passerine birds, in which it can cause systemic coccidiosis. The complete mitochondrial genome sequences from two recently identified Isospora species; Isospora serinuse in a domestic canary and Isospora manorinae in a yellow-throated miner, were sequenced and compared with those of other closely related coccidian species. The complete mitochondrial genome sequence for Isospora serinuse is 6260. bp in size and 6223. bp for Isospora manorinae. The mitochondrial genomes of Isospora serinuse and Isospora manorinae include three protein-coding genes (COI, COIII and CytB), 19 LSU and 14 SSU rDNA fragments, including one newly identified putative LSU fragment in Isospora sp. The arrangement of coding regions in these two Isospora species were identical to that of available Isospora sp. and Eimeria spp. mitochondrial genomes and the start codon usage for protein coding genes was conservative. Phylogenetic analysis of the mt genome of the two Isospora species based on the three coding regions further support that the monophyletic nature of avian Isospora.
