RESUMO
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. CONCLUSION: 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.
