Isolation and identification of listeria in clinical material.

Results from research on isolation, identification, and study of biological properties of L. monocytogenes clinical isolates and Listeria spp test strains are presented. Peculiarities of modern research methods for indicating and identifying pathogenic listeria to improve the quality of laboratory studies of clinical material are studied.

A study of antibiotic and disinfectant susceptibility of Elizabethkingia meningoseptica.

For the local health service, Elizabethkingia meningoseptica remains a relatively new and little-known pathogen, whereas in many countries of Europe, Asia and other continents it is considered as a potential causative agent of nosocomial infections, especially in premature infants and immunocompromised patients. An analysis of the literature data, as well as our results indicate that E. meningoseptica should be considered as a potential pathogen, which is characterized by a unique profile of susceptibility to antimicrobial agents (AMP) and disinfectants.

[THE NATIONAL NUTRIENT MEDIUM FOR DIAGNOSTIC OF PURULENT BACTERIAL MENINGITIS].

The national growth mediums were developed for isolating and cultivating of main agents of purulent bacterial meningitis--haemophilus agar, chocolate agar, PBM-agar. The growing and selective characteristics of developed growth mediums are examined. The haemophilus agar ensures growth of Haemophilus influenzae.

[Effect of cold plasma on the E. coli cell wall and plasma membrane].

The effect of cold plasma on E. coli cells was studied. It was shown that the treatment of E.

[Comparative assessment of dot-immunoassay and immunochromatography methods for detection of 01 serogroup of vibrio cholerae].

Aim: Comparative study of sensitivity and specificity of immunochromatographic (IC) assay kit and dot-immunoanalysis for assessment of feasibility of their use for laboratory diagnostics of cholera.

Materials And Methods: Experimental lots of IC assay kit and dot-immunoassay (DIA) for detection of Vibrio cholerae serogroup 01 serovars Ogava and Inaba were constructed on the basis of species-specific monoclonal antibodies (MCA) conjugated with colloid gold (IC) and peroxidase (DIA). Hybridoma-producer of MCAwas obtained and stored in liquid nitrogen in Rostov-on-Don Research Institute for Plague Control.
