Complete mitogenomes characterization and phylogenetic analyses of Ceratophyllus anisus and Leptopsylla segnis.

ABSTRACT: Fleas are one of the most common ectoparasites in warm-blooded mammals and an important vector of zoonotic diseases with serious medical implications. We sequenced the complete mitochondrial genomes of Ceratophyllus anisus and Leptopsylla segnis for the first time using high-throughput sequencing and constructed phylogenetic relationships. We obtained double-stranded circular molecules of lengths 15,875 and 15,785 bp, respectively, consisting of 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and two control regions. AT-skew was negative in both C. anisus (-0.022) and L. segnis (-0.231), while GC-skew was positive in both (0.024/0.248), which produced significant differences in codon usage and amino acid composition. Thirteen PCGs encoding 3,617 and
