title: [Simple qualitative methods of detecting beta-lactamase-producing strains of microorganisms].
abstract: Modifications of two microbiological qualitative methods for detection of beta-lactamase-producing microbial strains are described. The methods are based on the principle of Goths. One of the methods named "contact" significantly differs from the prototype and is more simple, convenient, easily reproducible and does not require the use of special equipment and special training of the staff.
