title: [Epidemiological survey of echinococcosis in some areas of Jiangsu Province].
abstract: OBJECTIVE
  To understand the prevalence of echinococcosis in some areas of Jiangsu Province, so as to provide the evidence for making practical control measures.
  
  
  METHODS
  The cases were determined by a retrospective survey and case-clues survey. All canine feces were tested by immunological fecal antigen in the villages of the local infection suspected cases. The antigen-positive feces were detected for E. chinococcus eggs by Kato-Katz technique. A serological investigation was administrated to search infected persons by double methods of enzyme-labeled immune assay and point immuno-gold filtration assay in the focus groups around the local infection suspected cases, and some students aged from seven to twelve years in their townships and in five different-orientation townships sampled randomly in their counties. The antibody-positive people were confirmed further by using imaging detection.
  
  
  RESULTS
  There were 10 imported cases and 16 local infection suspected cases. Twenty canine feces were positive among 1 938 samples, and the positive rate was 1.03%. However, no pathogen was found. Of 12 473 serum samples, 72 were positive in sera immunological antibody test (0.58%), but no cystic nodules were found by imaging detection.
  
  
  CONCLUSIONS
  There is no direct evidence for confirming the presence of infectious source and foci of echinococcosis in Jiangsu Province. However, the surveillance of echinococcosis is still needed.
