Associative Genetic Diversity of Theileria Annulata Calf Isolates from Northern India Based on Cyt B Gene
Purpose
Molecular epidemiological studies focusing on the phylogenetic characterization of Theileria annulata are crucial for understanding the evolutionary history of the parasite worldwide. The current study reveals genetic diversity among Indian isolates of T. annulata based on the cyt b gene.
Method
In the present study, cyt b gene from 6 calf isolates of T. annulata was amplified; custom sequenced and accession numbers: MH778940-MH778945 were obtained.
Result
Two haplotypes were identified, differing by nucleotide substitutions at positions 710 (thymine to adenine) and 1076 (cytosine to guanine). Isolates from Northern India formed a distinct cluster on the phylogenetic tree compared to those from Southern India and showed closer phylogenetic similarity to Iranian isolates than to other Asian counterparts.
Conclusion
Important phylogenetic data has been generated from the present study suggestive of marked genetic variability in T. annulata isolates across the globe.
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.
