ABSTRACT
Objective To develop a rapid test for the detection of F1 antigen of Yersinia Pestis based on gold-immunochromatography.Methods F1 antibodies were coupled with colloidal gold to prepare collidal gold reagent,which was used to detect F1 antibodies based on double antigen sandwich.The collidal gold reagent was estimated for its sensitivity specificity and stablity in labs and 1798 samples were detected in 17 surveillance spots.Results The reagent was sensitive to 0.0010 g/L F1 antigens.The reagens kept stable when it had been placed at 4℃ or room-temperature for 12 months and did not react to Yersinia pseudotuberculosis and Yersinia enterolitica.In 17 surveillance labs the reagent was used to test 1798 viscera samples from animal.resulting an accordance rate of 97.11%(1746/1798)to bacterial culture and 96.83%(1741/1798)accordance to reverse indirect hemagglutination assay(RIHA),showing a higher detection rate[9.23%(166/1798)]compared with RIHA[6.79%(122/1798)]and bacterial culture[6.28%(113/1798)].Conclusions The collidal gold reagent,sensitive and specific in diagnosing Yersinia pestis infection of both human and animals,is a rapid method in surveillance spot.
