Activity of tigecycline alone and in combination with colistin and meropenem against Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae strains by time-kill assay
Pournaras, S.; Vrioni, G.; Neou, E.; Dendrinos, J.; Dimitroulia, E.; Poulou, A.; Tsakris, A. (2011)Antibiotic combinations including tigecycline have not been studied against Klebsiella pneumoniae carbapenemase (KPC)-producing pathogens. Tigecycline alone and combined with colistin and meropenem was tested against eight ... -
Characteristics of Meropenem Heteroresistance in Klebsiella pneumoniae Carbapenemase (KPC)-Producing Clinical Isolates of K-pneumoniae
Pournaras, S.; Kristo, I.; Vrioni, G.; Ikonomidis, A.; Poulou, A.; Petropoulou, D.; Tsakris, A. (2010)Meropenem heteroresistance was investigated in six apparently meropenem-susceptible, Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) clinical isolates, compared with that in carbapenemase-negative, ... -
A Combined Disk Test for Direct Differentiation of Carbapenemase-Producing Enterobacteriaceae in Surveillance Rectal Swabs
Pournaras, S.; Zarkotou, O.; Poulou, A.; Kristo, I.; Vrioni, G.; Themeli-Digalaki, K.; Tsakris, A. (2013)Carbapenemase-producing Enterobacteriaceae (CPE) are rapidly spreading worldwide. Early detection of fecal CPE carriers is essential for effective infection control. Here, we evaluated the performance of a meropenem combined ... -
Comparative Evaluation of Combined-Disk Tests Using Different Boronic Acid Compounds for Detection of Klebsiella pneumoniae Carbapenemase-Producing Enterobacteriaceae Clinical Isolates
Tsakris, A.; Themeli-Digalaki, K.; Poulou, A.; Vrioni, G.; Voulgari, E.; Koumaki, V.; Agodi, A.; Pournaras, S.; Sofianou, D. (2011)The accurate phenotypic detection of Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae is an increasing necessity worldwide. We evaluated the performance of boronic acid combined-disk tests using as ... -
Detection of the new metallo-beta-lactamase VIM-19 along with KPC-2, CMY-2 and CTX-M-15 in Klebsiella pneumoniae
Pournaras, S.; Poulou, A.; Voulgari, E.; Vrioni, G.; Kristo, I.; Tsakris, A. (2010)To report the identification of the metallo-beta-lactamase (MBL) variant VIM-19 in a Klebsiella pneumoniae clinical strain co-producing KPC-2 carbapenemase, CMY-2 cephalosporinase and CTX-M-15 extended-spectrum beta-lactamase. ... -
The effect of homocysteine on the clinical outcomes of ventilated patients with severe sepsis
Tsantes, A.; Tsangaris, I.; Nikolopoulos, G.; Bagos, P.; Kopterides, P.; Antonakos, G.; Dimopoulou, I.; Vrioni, G.; Kapsimali, V.; Dima, K.; Armaganidis, A.; Travlou, A. (2010)Background. There is considerable evidence that elevated plasma homocysteine levels are associated with a prothrombotic milieu, whereas activation of the coagulation cascade is an important component of the pathogenesis ... -
Heteroresistance to Meropenem in Carbapenem-Susceptible Acinetobacter baumannii
Ikonomidis, A.; Neou, E.; Gogou, V.; Vrioni, G.; Tsakris, A.; Pournaras, S. (2009)The characteristics of carbapenem heteroresistance were studied in 14 apparently carbapenem-susceptible Acinetobacter baumannii isolates. The MICs for carbapenems were determined, and the isolates were genotyped by ... -
A simple phenotypic method for the differentiation of metallo-beta-lactamases and class A KPC carbapenemases in Enterobacteriaceae clinical isolates
Tsakris, A.; Poulou, A.; Pournaras, S.; Voulgari, E.; Vrioni, G.; Themeli-Digalaki, K.; Petropoulou, D.; Sofianou, D. (2010)The increasing frequency of class A KPC enzymes and class B metallo-beta-lactamases (MBLs) among Enterobacteriaceae as well as their possible co-production makes their early differentiation urgent. A simple phenotypic ...
