The complete mitochondrial genome of a flea, Jellisonia amadoi (Siphonaptera: Ceratophyllidae).

The complete mitogenome sequence of the flea, Jellisonia amadoi (Siphonaptera: Ceratophyllidae), was sequenced. The 17,031 bp long genome has the standard metazoan complement of 37 genes, in the insect ancestral genome arrangement. The very large (2338 bp) A + T rich region is marked by two macro-repeats and multiple microsatellite and homopolymer regions. The protein-coding, rRNA and tRNA genes are all highly similar to homologues in related insect orders - similar length, few indels and high proportion of invariant sites. Sequencing of a flea mitogenome provides data for one of the last three insect orders from which data were lacking and provides further proof that parasitic life histories alone do not cause aberrant mitogenomes.
