An evaluation of two methods of bacteriocine typing of organisms of the genus Proteus.

An assessment of two simple methods of typing Proteus isolates using bacteriocines is described. The methods chosen were those of Cradock-Watson and Al-Jumaili. It has been shown that the use of liquid bacteriocine preparations is more satisfactory than methods involving proteocine production in solid media. For example, no non-typable isolates were encountered and a large number of strains were demonstrated. This method is therefore proposed for use in a routine diagnostic laboratory.
