Ticks Tick Borne Dis
November 2024
Article Synopsis
- Tick-borne pathogens from the Rickettsia genus cause serious diseases in humans and dogs, and climate and land use changes are expanding their vector ranges, potentially introducing new pathogens in unexposed areas.
- A study in Chad found that 43.3% of ticks from domestic dogs were positive for Rickettsia spp., with six identified species including some known zoonotic pathogens like R. africae and R. felis.
- The results highlight a significant diversity of Rickettsia in ticks, particularly in Rh. muhsamae, indicating a risk of rickettsiosis in Chad, and emphasize the need for more research on ticks and these pathogens in the region.

Article Synopsis
- Dracunculus medinensis, known as Guinea worm, is a parasitic infection targeting both humans and domestic dogs, prompting the need for new treatment methods due to rising infections in dogs.
- Two clinical trials tested the effectiveness of flubendazole (FBZ) injections on GW infections: one on ferrets and another on dogs in Chad, revealing different results between the two.
- Ferrets showed promising results with reduced worm viability, while the dog trial did not demonstrate significant effects, indicating that treatment timing and intervals might need to be adjusted for better outcomes in future research.
