title: [Fleas notified on Microtus fuscus foci in Sichuan province].
abstract: OBJECTIVE
  To analyzed the variant information on the indices regarding fleas from natural foci of Microtus plague in Sichuan epidemic area during 2000 to 2008.
  
  
  METHODS
  Statistical and analytical methods were used on the surveillance data regarding Microtus fuscus plague.
  
  
  RESULTS
  There were 19 flea species identified and the share of Callopsylla sparsity was 62.79 percent while the share of Amphipsylla tuta was 30.90 percent on Microtus fuscus plague. The infection rate of fleas and the flea index were the highest in October and the lowest in December and March. Species as Callopsylla sparsity, Amphipsylla tuta and Rhadinopsylla dahurica vicina could naturally infect the Yersinia pestis.
