Article Synopsis
- Angiostrongylus vasorum, or "French heartworm," is a serious parasite first identified in a dog in France, known for causing severe health issues in dogs, and has not been previously studied in Algeria.
- The study involved examining 47 road-killed animals over 18 months across six regions in Algeria, using both histological and molecular methods to identify lungworms.
- Results confirmed the presence of A. vasorum in a golden African wolf for the first time, indicating a need for more research on the spread and impact of this parasite in Algeria.
