Activity of Tigecycline in Combination with Colistin, Meropenem, Rifampin, or Gentamicin against KPC-Producing Enterobacteriaceae in a Murine Thigh Infection Model
Michail, G.; Labrou, M.; Pitiriga, V.; Manousaka, S.; Sakellaridis, N.; Tsakris, A.; Pournaras, S. (2013)Limited antimicrobials remain active for treating severe infections due to KPC-producing pathogens, and optimal regimens have not been established. In murine thigh infections caused by nine KPC-producing clinical strains ... -
Comparative Evaluation of Tigecycline Susceptibility Testing Methods for Expanded-Spectrum Cephalosporin- and Carbapenem-Resistant Gram-Negative Pathogens
Zarkotou, O.; Pournaras, S.; Altouvas, G.; Pitiriga, V.; Tziraki, M.; Mamali, V.; Themeli-Digalaki, K.; Tsakris, A. (2012)We evaluated the Vitek2, Etest, and MIC Test Strip (MTS) methods of tigecycline susceptibility testing with 241 expanded-spectrum cephalosporin-resistant and/or carbapenem-resistant Enterobacteriaceae and Acinetobacter ... -
Dissemination of Clinical Isolates of Klebsiella oxytoca Harboring CMY-31, VIM-1, and a New OXY-2-Type Variant in the Community
Tsakris, A.; Poulou, A.; Markou, F.; Pitiriga, V.; Piperaki, E. T.; Kristo, I.; Pournaras, S. (2011)The aim of the present study was to investigate the epidemiological link of multidrug-resistant Klebsiella oxytoca isolates causing community-onset infections among patients attending our outpatient department and to ... -
Predictors of mortality in patients with bloodstream infections caused by KPC-producing Klebsiella pneumoniae and impact of appropriate antimicrobial treatment
Zarkotou, O.; Pournaras, S.; Tselioti, P.; Dragoumanos, V.; Pitiriga, V.; Ranellou, K.; Prekates, A.; Themeli-Digalaki, K.; Tsakris, A. (2011)Bloodstream infections (BSIs) caused by Klebsiella pneumoniae carbapenemases (KPC)-producing K. pneumoniae (KPC-KP) are associated with high mortality rates. We investigated outcomes, risk factors for mortality and impact ... -
Recurrent healthcare-associated community-onset infections due to Klebsiella pneumoniae producing VIM-1 metallo-beta-lactamase
Poulou, A.; Spanakis, N.; Pournaras, S.; Pitiriga, V.; Ranellou, K.; Markou, F.; Tsakris, A. (2010)To investigate the extrahospital dissemination of carbapenem-resistant Klebsiella pneumoniae isolates and the mechanisms of acquired resistance. Patients who were referred to the outpatient department of Serres General ... -
Susceptibility patterns to extended-spectrum cephalosporins among Enterobacteriaceae harbouring extended-spectrum beta-lactamases using the updated Clinical and Laboratory Standards Institute interpretive criteria
Kristo, I.; Pitiriga, V.; Poulou, A.; Zarkotou, O.; Kimouli, M.; Pournaras, S.; Tsakris, A. (2013)We examined the effect of applying the updated 2010 Clinical and Laboratory Standards Institute (CLSI) susceptibility breakpoints for extended-spectrum cephalosporins (ESCs) to detect extended-spectrum beta-lactamase ... -
Trends in antimicrobial resistance of clinical isolates of Enterococcus faecalis and Enterococcus faecium in Greece between 2002 and 2007
Protonotariou, E.; Dimitroulia, E.; Pournaras, S.; Pitiriga, V.; Sofianou, D.; Tsakris, A. (2010)We analysed trends in antimicrobial resistance of Enterococcus faecalis (N = 1498) and E. faecium (N = 625) recovered from clinical infections during 2002-2007 in a Greek tertiary care hospital. Molecular assays were used ...
