First Phylogenetic Perspective on Molecular Epidemiology of Echinococcus granulosus sensu lato in Dogs in Sistan and Baluchestan Province, Southeastern Border of Iran |
|
| چکیده انگلیسی مقاله |
Background: Echinococcosis or Hydatid disease is a zoonotic disease that is caused by Echinococcus granulosus. The disease is a high public health concern in Iran, but there is little known about the genetic diversity and epidemiology of Echinococcus spp. in Iranian shepherd dogs. Materials and Methods: Fifty shepherd dogs were investigated for the adult worm of E. granulosus from May 2020 to April 2021 in Sistan and Baluchestan Province, the southeastern border of Iran. DNA extraction of samples and amplifying was done, and sequence analysis of mitochondrial genes (Cox1 and Nad1) was performed. Results:Out of 50 shepherd dogs, 11 cases (22%) were infected with E. granulosus. No significant difference was observed regarding demographic factors (P>0.05). The phylogenetic analyses of Cox1 and Nad1 sequences demonstrated G1 genotype (sheep strains) in all isolates. Based on sequence analyses, a low (Cox1, Hd [haplotype diversity: 0.200; Hn [number of haplotypes]: 2) to moderate (Nad1, Hd: 0.533; Hn: 4) genetic (haplotype) diversity of E. granulosus G1 genotype and low nucleotide diversity (π: 0.00052-0.00243) were observed. Conclusion: The first identification of a sheep strain (G1) in the final host in Sistan and Baluchestan Province indicates that potential intermediate hosts play a secondary role in preserving the biology of the dog-sheep cycle. The present study's findings enrich our knowledge about the prevalence of E. granulosus, the classification of strains, and the genetic diversity of the parasite in Iranian herding dogs. This information helps develop strategies and programs for monitoring and controlling infection in stray dogs in the region |
