Characterization of the Complete Mitochondrial Genome of Fischoederius elongatus Derived from Cows in Shanghai, China

الملخص EN

A study was conducted to reveal the characterization of the complete mitochondrial genome of Fischoederius elongatus derived from cows in Shanghai, China.

Results indicated that the complete mt genome of F.

elongatus was 14,288 bp and contained 12 protein-coding genes (cox1-3, nad1-6, nad4L, atp6, and cytb), 22 transfer RNA genes, and two ribosomal RNA genes (l-rRNA and s-rRNA).

The overall A + T content of the mt genome was 63.83%, and the nucleotide composition was A (19.83%), C (9.75%), G (26.43%), and T (44.00%).

A total of 3284 amino acids were encoded by current F.

elongatus isolate mt genome, TTT (Phe) (9.84%) and TTG (Leu) (7.73%) codon were the most frequent amino acids, whereas the ACC (Thr) (0.06%), GCC (Ala) (0.09%), CTC (Leu) (0.09%), and AAC (Asn) (0.09%) codon were the least frequent ones.

At the third codon position of F.

elongatus mt protein genes, T (50.82%) was observed most frequently and C (5.85%) was the least one.

The current results can contribute to epidemiology diagnosis, molecular identification, taxonomy, genetic, and drug development researches about this parasite species in cattle.
