[Evaluation of external laboratory test results for the correct identification and determination of chemotherapeutic sensitivity of staphylococci in bacteriologic provincial laboratories of sanitary-epidemiologic stations in 1995].
In the tests bacteriological laboratories participated in 45 sanitary-epidemiological stations. Each station was given two strains of staphylococci: S. epidermidis and S. aureus homogeneously resistant to methicillin (MRSA) or S. aureus sensitive to methicillin (MSSA), and S. aureus coagulase-negative and clumping-factor-positive strain. The analysis was carried out of the results of control identifications of strains of the determinations of the sensitivity of the identified strains to antibiotics. Among the studied strains the greatest difficulty in identification were caused by the coagulase-negative strain of S. aureus. In the determination of the sensitivity of the control strains to chemotherapeutic agents abnormalities were found in the technique of antibiogram performing and incorrect selection of discs for antibiograms as well as erroneous interpretation of the results.
