Carriage of ESBL- and AmpC-positive Enterobacteriaceae in the gastrointestinal tract of community subjects and hospitalized patients in the Czech Republic.

Aim: The study aimed at analyzing ESBL- and AmpC-positive Enterobacteriaceae in the gastrointestinal tracts of university hospital inpatients and persons from the Olomouc Region community, and comparing the results with data from 2007.

Methods: Bacteria were isolated from rectal swabs inoculated onto the ChromID(TM) ESBL selective medium (bioMérieux). Production of ESBL-type beta-lactamases was confirmed by the modified double-disk synergy test and AmpC enzyme production was detected by the AmpC disk test.

Prevalence of ESBL-positive bacteria in the community in the Czech Republic.

Background: Problematic bacteria in the community include enterobacteria which produce extended-spectrum beta-lactamases. As yet there is no description of the prevalence of these bacteria in persons in the community in the Czech Republic. Therefore the main goal of this study was to determine the prevalence of ESBL-positive enterobacteria in the gastrointestinal tracts of subjects in the community in the Czech Republic.

Prevalence of vancomycin-resistant enterococci in hospitalized patients and those living in the community in the Czech Republic.

Between July 1, 2002 and December 31, 2003, rectal swabs from both hospitalized patients and community subjects in the Czech Republic were taken to ascertain the prevalence of vancomycin-resistant enterococci (VRE). The swabs were used for isolating and identifying enterococci and their susceptibility to antibiotics. Vancomycin resistance phenotypes were verified by PCR detection of vanA, vanB, vanC1 and vanC2 genes.

Occurrence of vancomycin-resistant enterococci in humans and animals in the Czech Republic between 2002 and 2004.

In the period between September 2002 and May 2004, a total of 6023 rectal swabs from humans in the Czech Republic were evaluated and 821 Enterococcus spp. strains were isolated. Nine strains (1.

Utilisation of macrolides and the development of Streptococcus pyogenes resistance to erythromycin.

Objectives: The aim of the study was to evaluate the relationship between the development of the resistance of Streptococcus pyogenes strains to erythromycin and the utilisation of macrolides in the Olomouc region, Czech Republic.

Method: During the period 1997-2001, data for utilisation of macrolides was obtained from the database of the regional General Health Insurance Company and expressed indefined daily doses per 1,000 patients per day. S.

Prevalence of vancomycin-resistant enterococci in hospital and community environment.

Aim Of The Study: The presented study aimed at determining the prevalence of vancomycin-resistant enterococci (VRE) in rectal swabs taken from both patients in the Teaching Hospital in Olomouc (THO), Czech Republic, and subjects from the community setting of the hospital's catchment area.

Materials And Methods: Between July 1, 2002 and July 1, 2003, rectal swabs were taken from the THO patients as well as individuals from the community catchment area to be utilized for isolating and identifying enterococci and their suscetibility to antibiotics. Vancomycin resistance phenotypes were verified by PCR detection of vanA, vanB, vanC1 and vanC2 genes.

Utilization of fluoroquinolones and Escherichia coli resistance in urinary tract infection: inpatients and outpatients.

Objectives: The aim of this study was to evaluate the dependence of Escherichia coli resistance to fluoroquinolones on their use in the outpatients and inpatients in the Olomouc region of the Czech Republic.

Methods: Data on inpatient antibiotic use were obtained from the database of the Department of Pharmacology and expressed as defined daily dose per 100 bed-days (DBD). Data on outpatient prescriptions were obtained from the database of General Health Insurance Company and expressed in defined daily doses per 1000 clients per day (DID).

Molecular-biological analysis of vancomycin-resistant enterococci isolated from a community in the Czech Republic.

Objective: To determine the occurrence of vancomycin-resistant enterococci (VRE) in a community of the Czech Republic and a molecular-biological analysis of the VRE isolated.

Methods: Enterococci were isolated from the rectal swabs of healthy people in the Olomouc region (population 300,000), Czech Republic in the period of January-December 2003. The molecular-biological analysis of VRE was performed by analysis of isolated DNA, which was cleaved by restriction enzyme SmaI and separated by pulse field gel electrophoresis (PFGE).
