Comparative Study of ELISA and Y-1 Cell Test for Detection of Thermo-labile Enterotoxin of Escherichia coli

By taking advantage of presence of cross imm unoreaction between thermo-labile enterotoxin of Escherichia coli(LT) and cholera toxin (CT), anti CT-ELISA was developed for detection of LT and was compared with the Y- 1 cell test. The rate of coincidence in detection of 68 strains of Escherichia coli by these two methods 97% and the P/N value of anti CT-ELISA was closely with the intensity of Y-1 cell reaction(r=0.88).
