[A new zoonosis--investigation of Gardnerella vaginalis disease of fox. IV. Study of dot-ELISA for the detection of serum antibody of Gardnerella vaginalis disease of fox].

192 Gardnerella vaginalis antibody positive sera from artifically infected foxes, immunized foxes and foxes that the bacterial examination were positive were analysed by the established Dot-ELISA. The results showed that 187/192 were positive, the positive rate was 97.3%. Block and cross tests showed that the method was specific. The method was 28.1 times sensitive as PAT and 5.5 times sensitive as MAT respectively. The repeatability of the test was good and the positive coincidence rate among the three techniques was 100%.
