Molecular characterization of Peste des petits ruminants virus (PPRV) in sheep and goats and risk factors associated with it in selected districts of Khyber Pakhtunkhwa-Pakistan.
Background: Peste des Petits Ruminants (PPR) is an economically significant transboundary viral disease of sheep and goats caused by the PPRV virus, affecting annual losses of 1.45-2.10 billion US dollars globally. We designed the current study to evaluate the positive cases, molecular characterization, phylogenetic analysis, and risk factors correlated with the disease in various districts of Khyber Pakhtunkhwa, Pakistan, with the aim of contributing to these strategies.
Methods and results: A total of 384 samples from three selected districts, i.e., Peshawar, Charsadda and Chitral (n = 128 each), were collected, and the virus was investigated by using the sandwich ELISA, while the N gene of the virus was used as a target for molecular detection via RT-PCR. The confirmed samples were then sequenced, and phylogenetic analysis was performed. According to our findings, the highest positive cases was found in district Peshawar (50.87%), followed by Charsadda and Chitral (24.56%), respectively, while risk factor analysis showed that certain categories, such as species, sex, and age less than two years, have higher risk (P < 0.05) in contrast to their respective categories. Furthermore, sequencing and phylogenetic analysis of representative samples showed that the PPRV strains in the current study clustered in lineage IV, which is circulating in the small ruminant population of Asia, the Middle East, and African countries. Comparative residue analysis highlighted the mutation by representing 242 variable sites out of 371 locations.
Conclusions: PPRV has foremost importance in Pakistan because the virus was detected in a considerable number of samples, and most of which were sourced from subsidiary areas where veterinary services are not prioritized.
期刊介绍:
Molecular Biology Reports publishes original research papers and review articles that demonstrate novel molecular and cellular findings in both eukaryotes (animals, plants, algae, funghi) and prokaryotes (bacteria and archaea).The journal publishes results of both fundamental and translational research as well as new techniques that advance experimental progress in the field and presents original research papers, short communications and (mini-) reviews.
