First field work on alveolar echinococcosis in Kirghizstan. 13 juin 2012

publié le , mis à jour le

Alveolar echinococcosis is a potentially fatal parasitic disease that causes tumour-like lesions in the human liver. It is contracted from dog or fox “definitive hosts” which harbour the gut stage adult tapeworm. The parasite cycle involves also intermediate host small mammals such voles and pikas (small lagomorphs) which harbour the larval liver stage.

Large foci of transmission have been discovered in Western China since the 80’s and in Central Asia (Kirghizstan, Kazakhstan, etc.) more recently. Little is known on the ecology of hosts and parasites in those areas. This programme is supported by the Welcome Trust.
The Chrono-environment department is investigating the interactions between landscape and small mammal intermediate host communities in Central Asia (Kirghizstan and the Tibetan plateau of Western Sichuan).
The works are carried out in collaboration with the University of Salford, UK, the Sichuan CDC, China, the Veterinary Institute, Bishkek, Kirghizstan, the University of Zurich, CH and the University of Asahikawa, Japan.

2012, May 7-23 : first field work in the Allai valley, Pamir, Kirghizstan

Dog infection and small mammal communities have been investigated around Sary Moghol (3000 m alt), Allai valley, at the bottom of the Lenine Peak (7134m). Patrick Giraudoux, Eve Afonso and Nicolas Tete were part of the crew. Their aim was to provide a first assessment of small mammal communities and landscape and to analyse possible landscape effects on population dynamics. The team also included Phil Craig, Mike Rogan, Mark Danson, Alex Mastin, Freya van Kesteren (Salford University, UK), Iskender Ziadinov, Bermet Mutunova (Veterinary Institute, Bishkek, Kirghizstan). Paul Torgerson (University of Zurich, CH).
