Improved method for cholera diagnosis

The use of the oxidase test is proposed to discover sparse colonies of cholera vibrios on a plate of Pril nutrient agar seeded directly with the suspected stool sample or after enrichment. This method also enables the detection of other oxidase-positive potential pathogens, such as non-agglutinating vibrios, Aeromonas hydrophila, Pseudomonas spp., and other nonfermentative organisms.
