RESUMO
Commercial system of multimicrotests for biochemical identification of enterobacteria MMT E2 and routine tube tests were compared in a controlled epidemiologic experiment with 205 enterobacterial strains. The system has been developed at the Allergen Research and Production Amalgamation. System MMT E2 fairly well met the requirements to diagnostic preparations of this kind; its results were compatible and well reproducible. This system in complex with commercial MMT E1 system may be used for species identification of enterobacteria. Practical application of both the systems will considerably simplify the process of identification of these microorganisms.

Comparative evaluation of a system of multimicrotests for biochemical identification of enterobacteria (MMT E1) developed at the ALLERGEN Research and Production Amalgamation and of tube tests for the same purpose in a controlled epidemiologic experiment has shown that the suggested system meets the requirements to such diagnostic preparations by all the major qualitative parameters (compatibility and reproducibility of the test results). Practical use of MMT E1 system will simplify and facilitate the process of enterobacteria identification.

Antigenic relations between meningococci, serogroups Z and 29E, have been studied with the use of serological methods. The thermolabile fractions of meningococci belonging to the above serogroups have been shown to contain common antigenic determinants which ensure the presence of serological cross reactions. Cross-reacting precipitating and agglutinating antibodies can be completely removed by the adsorption of meningococcal antisera, serogroups Z and 29E, with the cultures of heterologous serogroups. In the antisera adsorbed by meningococci belonging to heterologous groups a decrease in the titers of agglutinins, hemagglutinins and precipitins, particularly pronounced in adsorbed serogroup 29E antisera, has been observed.
