This study reveals that Echinococcus granulosus sensu stricto (E. granulosus s.s.) in Afghanistan is part of a global network, with livestock movement driving its spread. Findings aid in controlling this major zoonotic disease.
Area of Science:
- Parasitology
- Molecular Epidemiology
- Global Health
Background:
- Cystic echinococcosis (CE) is a significant zoonotic disease with limited molecular data from Afghanistan.
- Understanding parasite genetics is crucial for effective control strategies.
Purpose of the Study:
- To genetically characterize Echinococcus granulosus sensu stricto (E. granulosus s.s.) from Afghanistan.
- To investigate population structure and global phylogeographic relationships.
- To integrate findings into a worldwide mitochondrial dataset.
Main Methods:
- Sequencing of mitochondrial cox1 and nad1 genes from Afghan isolates.
- Analysis of genetic diversity, population structure, and phylogeography.
- Integration with a comprehensive global GenBank dataset.
Main Results:
- All Afghan isolates identified as E. granulosus s.s., predominantly genotype G1.
- Moderate to high haplotype diversity but low nucleotide diversity observed.
- Global analyses showed extensive intercontinental haplotype sharing, without host or geographic clustering.
Conclusions:
- Afghan E. granulosus s.s. populations are integrated into a global transmission network.
- Livestock movement and historical dispersal are key factors in CE epidemiology.
- Provides a framework for surveillance and control in endemic regions.
