The first notes on the metacestode of Echinococcus multilocularis in Lagurus luteus Eversmann from the Hobukser Mongolian Autonomous County,Xinjiang Uygur Autonomous Region

Abstract

Objective A quantitative surveillance of Lagurus luteus Eversmann was carried out on 24-28 September 2009,to ascertain the presence or absence of the infection of metacestode of Echinocccus multilocularis in the desert steppe of the state livestock farms on Hobukser Mongolian Autonomous county,Xinjiang Uygur Autonomous Region.Methods The quantitative survey on the rodents was carried out with caving open coefficient method.The rodents were captured by medium-sized rattrap.The captured Lagurus luteus were dissected and observed macroscopically for the metacestode of Echinococcus mutilocularis in liver,spleen and abdominal cavity.Results The density ofLagurus luteus is 103.68/hm2(1 hm2=10 000 m2).in the desert steppe.Total of 28 Lagurus luteus was captured and autopsied among them one was infected with metacestode of Echinococcus mutilocularis.The liver section showed characteristic alveolar cyst construction and matured protoscoleces,laminated,germinal layers and confirmed as naturally infection of metacestode of Echinococcus multilocularis.The infection rate was 3.57%.Conclusion This is the first finding of the Lagurus luteus as the intermediate host for Echinococcus multilocularis in China.
