To establish a new agglutination technique for detection of Enterotoxigenic Escherichia coli(ETEC) pili K88 ab,K99, 987 P and F41 genes based on colored silica microspheres(CSN) synthesized by reverse microemulsion method. The CSN surface was modificated by fimbriae mono-specific serum to prepare immune colored silica microspheres(ICSN). Then the method for rapid detection of ETEC pilus was established by optimization of reaction conditions. The results showed that the prepared ICSN was only reacted with th...
