[Methods of intraspecies differentiation of Enterobacter cloacae by biochemical reactions]

Three methods of intraspecies differentiation of Enterobacter cloacae by biochemical tests were compared on 14 clinical strains of different origin and 1 reference strain of this enterobacterium. The methods employed were the original and modified Old's method of biotyping and a method for assessing the biochemical profile of E. cloacae strains using bioMerieux API 20E system (France). Modified Old's method was found to be the most convenient for practical studies.
