[Microbiological monitoring of the microbic strain stability to antibacterial preparations in surgical in-patient clinics]. / Mikrobiologicheskii monitoring ustoichivosti k antibakterial'nym preparatam mikroorganizmov v khirurgicheskikh statsionarakh.

While performing of microbiological monitoring, conducted in surgical stationaries of Dnepropetrovsk, of 775 cultures, isolated during one year from patients and outer space, the S. aureus cultures were revealed, resistant to methicillin were 23.6%, to gentamycin 12.3% culture of all Gram-negative bacteria. Most effective preparation, which is recommended for the empirical antibacterial therapy conduction, is meronem, to whom the sensitivity of 87.5% for Gram-positive and 92.1% for Gram-negative cultures of conventionally pathogenic microorganism were established.

[Isolation of Yersinia enterocolitica in various conditions of cultivation]. / Vydelenie kishechnykh iersinii pri razlichnykh usloviiakh ku'ltivirovaniia.

The rates of Yersinia isolation from 156 samples of pathologic material cultivated by two methods, the routine one, with the selection of Yersinia from a microbial association by prolonged cooling of the examined material in slightly alkaline buffer and multiple inoculations into Endo's medium, and the technique suggested by the authors--a rapid method based on the treatment of the biologic material with a concentrated alkaline-salt mixture at 4 degrees C for 2 days and a single inoculation into inhibiting selective medium. Use of the rapid method has increased the isolation rate of Yersinia 4-fold, cut down the time of the investigation 2-3-fold, reduced the cost and simplified the technique of analysis.
