The mouse bioassay is a functional assay that detects biologically Energetic toxin. The assay demands a a few portion approach: toxin screening, toxin titer, And eventually toxin neutralization applying monovalent antitoxins. The procedure calls for two times of study at Each and every step.

On egg yolk medium, they sometimes show surface area iridescence when examined by oblique light. This luster zone, usually generally known as a pearly layer, generally extends beyond and follows the irregular contour with the colony. Aside from the pearly zone, colonies of C. botulinum
