Summary
Multicystic hydatids in Qinghai-Tibet plateau hares were identified as Echinococcus multilocularis. This finding confirms hares as a host for this parasite, potentially aiding its transmission on the Tibetan plateau.
Area of Science:
- Parasitology
- Molecular Biology
- Ecology
Background:
- Echinococcus multilocularis is a significant zoonotic parasite.
- The Qinghai-Tibet plateau is a unique ecosystem with endemic wildlife.
- The role of hares in the transmission cycle of E. multilocularis was previously unclear.
Purpose of the Study:
- To identify the species of Echinococcus causing hydatid disease in hares from the Qinghai-Tibet plateau.
- To investigate the potential role of hares in the transmission of Echinococcus multilocularis.
Main Methods:
- Necropsy of hares (Lepus oiostolus) from the Qinghai-Tibet plateau.
- Morphological examination of hydatid cysts.
- Mitochondrial DNA sequencing for species identification.
Main Results:
- Multicystic hydatid cysts were found in the livers of hares.
- Mitochondrial DNA sequencing confirmed the causative agent as Echinococcus multilocularis.
- Protoscolices were present within the hydatid cysts.
Conclusions:
- This study provides the first definitive confirmation of Echinococcus multilocularis larvae in hares.
- Hares may serve as a host and contribute to the transmission of Echinococcus multilocularis on the Tibetan plateau.
- Further research is needed to fully elucidate the transmission dynamics of Echinococcus multilocularis in this region.
