Starting from 1970, the notification of N. meningitidis cases in Poland was compulsory and separated from other cases of meningitis purulenta. Based on the experience of European Monitoring Group on Meningococci, the active surveillance of meningococcal meningitis in Poland was initiated in April 1995. It was the first time that such study was conducted to(More)
BACKGROUND Evaluation of the biocidal activity of chemical disinfectants and antiseptics according to European Standards (EN) is based on determination of the reduction of the number of viable test microorganisms under defined conditions. OBJECTIVE The objective of this study was to investigate whether reducing the neutralization time required following(More)
Enterococci despite their low pathogenicity are the third cause of hospital infections. Enterococci resistant to glycopeptides present special risks. The aim of this work was to determine the frequency of isolates of all enterococci versus enterococci resistant to glycopeptides from patients in the Transplant Surgery Ward. Moreover, vancomycin-resistant(More)
 The aim of this study was to investigate the Neisseria meningitidis carriage rate among two cohorts of Polish recruits upon entry to the military and during the first 2 months of their service, i.e. in the spring and autumn of 1998, and to characterize the meningococcal strains isolated. Pharyngeal swabs were taken four and five times from 151 and 168 men,(More)
BACKGROUND Currently, there is a wide range of products for mouth washing on the Polish market. They have different qualitative and quantitative compositions, and they differ particularly in the concentration of active substances. In antisepsis and disinfection, the significant reduction in number of cells of microorganisms in a particular environment is(More)
Retrospective study of bacterial meningitis cases was performed by analysis of filled questionnaires received from 38 different hospitals located in 27 out of 49 provinces of Poland. Obtained data allowed to indicate that S. epidermidis, N. meningitidis, S. pneumoniae and H. influenzae were the most common bacterial strains isolated from cerebrospinal fluid(More)
 The aim of this study was to investigate the genetic relationships among strains belonging to Neisseria meningitidis serotype 22 recovered in Poland from 1995 to 1998. Phenotypical characterisation of meningococcal strains isolated from patients with meningococcal disease has been performed since 1995. Strains belonging to Neisseria meningitidis type 22(More)
BACKGROUND The history of the investigation of standardized mycobactericidal activity of disinfectants and antiseptics is not very long. There is growing interest among the manufacturers of disinfectants in carrying out research on the antimicrobial activities in accordance with European standards (EN). This research could facilitate the introduction of(More)
The aim of this study was to analyse the activity interaction of aminoglycosides (gentamicin, kanamycin, streptomycin and dihydrostreptomycin) when combined with other antibiotics (lincomycin, benzylpenicillin, amoxicillin, cephalexin, spectinomycin and erythromycin), on selected clinical bacterial strains. The checkerboard method has been selected from the(More)
A study was conducted to investigate the quality of reference substances which were produced long before the introduction of advanced analysis and purification techniques. The quality and antimicrobial activity of WHO and EP oxytetracycline, doxycycline, colistin and spiramycin reference standards were assessed. The oldest substance was stored for 54 years(More)
