Qualitative correlation of the mouse neurotoxin and enzyme-linked immunoassay for deteriming Clostridium botulinum types A and B toxins

The efficacy of an enzyme-linked immunosorbent assay for botulinal toxin using polyclonal antibodies was evaluated in relation to the standard mouse assay. Qualitative tests for toxin in a meat system inoculated with Clostridium botulinum and pure cultures of various aerobic and anaerobic bacteria s...

Summary:The efficacy of an enzyme-linked immunosorbent assay for botulinal toxin using polyclonal antibodies was evaluated in relation to the standard mouse assay. Qualitative tests for toxin in a meat system inoculated with Clostridium botulinum and pure cultures of various aerobic and anaerobic bacteria showed that both the mouse neurotoxin and enzyme-linked immunosorbent assays detected toxin in the samples. However the ratios of mouse:ELISA activity of culture supernatant toxins of C. botulinum showed wide disparity, among strains of types A and B. Trypsin treatment resulted in a slight loss of ELISA activity but the mouse response increased.
