Resistance of Klebsiella pneumoniae strains producing and not producing ESBL (extended-spectrum beta-lactamase) type enzymes to selected non-beta-lactam antibiotics.

Background: Bacteria of the Klebsiella genus may cause numerous infections in human, which are often treated with beta-lactam antibiotics. The fundamental mechanism of Klebsiella resistance to penicillins or cephalosporins involves the production of enzymes--extended-spectrum beta-lactamases (ESBLs). Because of resistance of many Klebsiella spp.

[Susceptibility to antibiotics of some species of Enterobacter isolated from various clinical materials].

We investigated 185 strains of Enterobacter spp. (E. cloacae--143 strains, E.

[In vitro assessment of the sensitivity of Candida albicans strains isolated from the vagina on basis antimycotics].

Objective: The purpose of the study was to analyses the sensitivity of 73 randomly selected Candida albicans strains isolated from the vagina of pregnant and delivering women against seven basic antimycotics.

Materials And Methods: The microtest FUNGITEST (Sanofi Diagnostics Pasteur) was applied in assessing the sensitivity of 5-fluorocytosin, amphotericin B, ketoconazol, fluconazol, itraconazol and miconazol and the disk-diffusion method with the use of a Casitone base for nystatin.

Results And Conclusions: Variations in the sensitivity against drugs have been noted between individual strains of Candida albicans species.

[Vaginal candidiasis: frequency of occurrence and risk factors].

Objective: Our purpose was to determine the incidence, risk factors and pregnancy outcome among women with vaginal growth of Candida species.

Materials And Methods: In the period from January 1, 1994 to December 31, 1997 inoculation results have been assessed of vaginal secretions collected on a standard Sabouraud base and demographic data has been collected of 10,825 pregnant women delivering in single and full-term pregnancy in the Municipal Hospital in Bydgoszcz.

Results And Conclusions: Positive inoculation results for Candida sp.

[Yeast species identification in vulvovaginal candidiasis: susceptibility to nystatin].

Objective: The rates of Candida species and susceptibility to nystatin were evaluated.

Materials And Methods: In the period from January 1, 1998 to December 31, 1998 mycological tests have been carried out for identification of yeast species in the group of pregnant and delivering women hospitalized in the Obstetrics-Gynecological Departments of the Municipal Hospital in Bydgoszcz. We used two commercial media: Albicans ID and CHROMagar Candida.
