The ability ofC. parapsilosis (an important cause of nosocomial infections) to produce biofilm was evaluated in 32 bloodstream isolates and 85 strains isolated from skin. The biofilm formation was found in 19 (59%) blood isolates and only in 33 (39%) isolates from skin. The antifungal susceptibility was assessed for amphotericin B, itraconazole and(More)
The ability ofStaphylococcus epidermidis to produce biofilm was compared in 147 clinically significant strains repeatedly isolated from blood cultures of patients with bloodstream infection and in 147 strains isolated from skin. The strains were examined for the presence ofica operone, for the ability to form biofilm by Christensen’s test-tube method and(More)
detection introduced the possibility of early targeted antimicrobial treatment that, in turn, may improve the outcome of patients with sepsis [1]. We retrospectively evaluated 54 results of the SeptiFast test from patients with solid malignancy admitted to the ICU between June 2009 and August 2011. Specimens from suspected bloodstream infection were(More)
BACKGROUND Yeasts of the genus Candida are important opportunistic pathogens responsible for severe bloodstream infections in immunocompromised patients. An important virulence factor that allows them to colonize plastic implants and to survive in the blood is their ability to form biofilm. The purpose of the study was to assess, how frequently this(More)
BACKGROUND Rhodococcus equi (formerly Corynebacterium) has been long considered an exclusively zoopathogenic microbe causing mainly granulomatous pneumonias and lung abscesses in young foals. The aim of this paper was to analyse substantial features of R, equi infections hitherto reported in man. METHODS AND RESULTS MEDLINE database was searched for(More)
OBJECTIVE One of the most important threats of current medicine is the spread of multiresistant Gram-negative bacteria. We report here data from a six-month prevalence study on carbapenemase-producing K. pneumoniae and E. coli performed in Czech hospitals participating on European Survey on Carbapenemase-Producing Enterobacteriaceae (EuSCAPE). METHODS Ten(More)
Nosocomial infections caused by biofilm-positive microorganisms are a serious therapeutic problem. In the biofilm, microorganisms are protected against adverse effects of the external environment, including the action of antibiotics. It is well known that the values of minimum inhibitory concentrations (MIC) determined for planktonic forms do not correspond(More)
STUDY AIM To determine antibiotic resistance and incidence of multidrug resistance among Nontyphoidal salmonellae serovars isolated from humans. MATERIAL AND METHODS Consecutive Salmonella isolates from patients, recovered in 48 microbiology laboratories in May 2012, were analyzed in the respective reference laboratories at the National Institute of(More)
INTRODUCTION The aim of our study was to identify risk factors associated with the development of Clostridium difficile colitis and determining the severity of clostridial colitis in a group of surgical patients. Identification of its predispositions is necessary for preventive interventions and effective treatment. MATERIAL AND METHODS 51 patients(More)
