Abstract
AbstractSection
Purpose
This study presents the first mitogenome sequencing of Aviostivalius klossi bispiniformis and provides a morphological description, while evaluating the phylogenetic position of Pygiopsyllidae within Siphonaptera.
AbstractSection
Methods
Morphological identification and imaging of A. k. bispiniformis were performed using a SZ2-ILST dissecting microscope, while its mitogenome was sequenced on the Illumina NovaSeq 6000 high-throughput sequencing platform. Bioinformatics softwares were used to annotate and analyze the structural characteristics and variations of the A. k. bispiniformis. Phylogenetic trees of Siphonaptera were constructed using both Maximum Likelihood (ML) and Bayesian analyses (BI).
AbstractSection
Results
The mitogenome of A. k. bispiniformis was 18,669 bp with a high AT content (79.7%). In A. k. bispiniformis, the trnL2 (UAA) gene exhibits a 9-bp anticodon loop, and the nad4-nad4L gene overlapping sequence was 10 bp. Both ML and BI analyses revealed an unstable phylogenetic position of Pygiopsyllidae within Siphonaptera.
AbstractSection
Conclusion
In conclusion, available phylogenetic analysis for fleas is subjected to partial taxa data and more taxa data is needed for further researches. This study promotes the understanding of evolution, genomics, and phylogeny of Pygiopsyllidae.
期刊介绍:
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
