title: Sequence Analysis of Mitochondrial Genome ofToxascaris leoninafrom a South China Tiger.
abstract: Toxascaris leoninais a common parasitic nematode of wild mammals and has significant impacts on the protection of rare wild animals. To analyze population genetic characteristics ofT. leoninafrom South China tiger, its mitochondrial (mt) genome was sequenced. Its complete circular mt genome was 14,277 bp in length, including 12 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 non-coding regions. The nucleotide composition was biased toward A and T. The most common start codon and stop codon were TTG and TAG, and 4 genes ended with an incomplete stop codon. There were 13 intergenic regions ranging 1 to 10 bp in size. Phylogenetically,T. leoninafrom a South China tiger was close to canineT. leonina. This study reports for the first time a complete mt genome sequence ofT. leoninafrom the South China tiger, and provides a scientific basis for studying the genetic diversity of nematodes between different hosts.
