Open pastures in Tibet showed more small mammal burrows than fenced areas, increasing Echinococcus multilocularis prevalence in dogs. Pasture type impacts parasite transmission.

Area of Science:

  • Veterinary Parasitology
  • Ecology
  • Epidemiology

Background:

  • Echinococcus multilocularis is a significant zoonotic parasite.
  • Pastoralist communities in Tibet rely on livestock and face potential parasite transmission risks.
  • Habitat characteristics can influence parasite life cycles and transmission dynamics.

Purpose of the Study:

  • To investigate the relationship between pasture management (open vs. fenced) and small mammal burrow density.
  • To assess the association between pasture type, burrow density, and Echinococcus multilocularis prevalence in domestic dogs.
  • To understand how land use practices may affect parasite transmission in Tibetan pastoral ecosystems.

Main Methods:

  • Field surveys were conducted in Tibetan pastoralist communities in 2003.

  • Small mammal burrow densities were quantified in open and fenced pasture types.
  • Dog fecal samples were analyzed for Echinococcus multilocularis infection.

    • Main Results:

    • Open pastures exhibited significantly higher densities of small mammal burrows compared to fenced pastures.
    • A higher prevalence of Echinococcus multilocularis was observed in dogs from areas with more burrows.
    • Pasture type was identified as a potential factor influencing Echinococcus multilocularis transmission.

    Conclusions:

    • Pasture management, specifically the distinction between open and fenced areas, is associated with small mammal habitat.
    • Increased small mammal burrow presence in open pastures correlates with higher Echinococcus multilocularis infection rates in dogs.
    • Findings suggest that pasture type plays a role in the transmission dynamics of Echinococcus multilocularis in Tibetan pastoral communities.
