Conventional methods for the detection of cholera toxin (CT) production by vibrios are not readily available to most laboratories. A modification is described here of a simplified method standardised earlier and based on the degradation of nicotinamide adenine dinucleotide (NAD) by CT; this is simple and can be carried out in small laboratories also. It is also easy to perform, and gives reproducible results.
