Abstract
Rodents are one of the most abundant and
successful mammals on the planet. The rats harbor the metacestode stage of
Hydatigerataeniaeformis serving as the intermediate hosts, whereas
cats act as definitive hosts of the parasite. The incidence of the larval stage
in rats has been documented in various regions of the world. To best of our
knowledge, the mainstream studies on the genetic diversity of
H. taeniaeformis are based on the
cox1 gene which precludes an in-depth
analysis of genetic variation in the parasite. To provide insights about
nad1 gene-based genetic variation, in
continuation of our previous work, we thereby in this study report H.
taeniaeformis infection in the urban murine population from the Faisalabad
district of Pakistan and presented genetic polymorphism using the
nad1 gene. Out of 38 isolates
investigated in the study, a total of 13 haplotypes were found with high
haplotype diversity (Hd = 0.909), while the nucleotide diversity was found to be
0.02340 in the study population. The neutrality study found a significant level
of nucleotide polymorphism, indicating a rise in low-frequency polymorphism,
which might be attributed to global population growth of the parasite.
Construction of phylogenetic comprising isolates from Kazakhstan, Finland,
Turkiye, Canada, Germany, France, and China revealed that Pakistani isolates of
H. taeniaeformisare distinct and formed a
separate cluster. Further research utilising full-length multiple
mitochondrial genes is required to understand the molecular epidemiology of
H. taeniaeformis on the global scale.
