Antimicrobial susceptibility of Gram-negative and Gram-positive bacteria collected from Eastern Europe: Results from the Tigecycline Evaluation and Surveillance Trial (T.E.S.T.), 2011-2016.

Objectives: The Tigecycline Evaluation and Surveillance Trial (T.E.S.

Global in vitro activity of tigecycline and linezolid against Gram-positive organisms collected between 2004 and 2009.

This study reports the antimicrobial activity of tigecycline and comparator antimicrobials, including linezolid, against Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecalis and Enterococcus faecium collected as part of the Tigecycline Evaluation and Surveillance Trial (T.E.S.

[Prevalence of ESBL-positive enterobacteriaceae in large moravian hospitals (Czech Republic)].

Background: bacterial infections have become an important issue in current medicine. Recently, their frequency and severity have significantly increased as a result of the rising number of resistant bacteria. One of important mechanisms of resistance is production of broad-spectrum beta-lactamases, namely the ESBL type.

[Practical experience with the detection Clostridium difficile].

Clostridium difficile is an important pathogen causing nosocomial diarrhoea and colitis which, in severe cases, may result in pseudomembranous colitis and eventually death. The main pathogenicity factors for C. difficile are toxins referred to as A and B.

[Prevalence of ESBL-positive strains of Klebsiella pneumoniae in the Czech Republic and their molecular biology analysis].

Background: One of the problems of contemporary medicine is an increasing number of bacterial strains with hazardous phenotypes of resistance. The feared bacterial pathogens include Klebsiella pneumoniae strains producing AmpA extended-spectrum beta-lactamases. The study focused on the molecular biological characteristics of ESBL-positive strains of Klebsiella pneumoniae collected in the Czech Republic.
