|Title:||GANGLIOSIDES INHIBIT SEROLOGICAL REACTIONS FOR THE DETECTION OF CHOLERA AND HEAT-LABILE ENTEROTOXINS OF ESCHERICHIA-COLI|
|Abstract:||GM1 ganglioside has been identified as the receptor for cholera toxin (CT) and heat-labile (LT) enterotoxin of Escherichia coli in many cell types. Using the radial immune hemolysis (RIH) and indirect hemagglutination (IH) tests described for the detection of these enterotoxins, a study was conducted on the 100% inhibition of these reactions by pre-incubating these enterotoxins with GM1, GD1 a and GT1 gangliosides. GM1 was found to be much more efficient than the other two. With respect to the RIH test, GT1 was more efficient than GD1 a as an inhibitor of enterotoxin binding. Similar results were obtained with the IH test. These data also showed that sheep red blood cells provide a good model system for the study of receptors for CT, LT and probably other enterotoxins which bind to gangliosides.|
