In Vitro and In Vivo Evaluations of Oxacillin Efficiency against mecA-Positive Oxacillin-Susceptible Staphylococcus aureus
Ikonomidis, A.; Michail, G.; Vasdeki, A.; Labrou, M.; Karavasilis, V.; Stathopoulos, C.; Maniatis, A. N.; Pournaras, S. (2008)Community-type Staphylococcus aureus strains that are positive for mecA and PBP2a but appear phenotypically susceptible to oxacillin are increasingly reported worldwide. Four S. aureus clinical isolates carrying the mecA ... -

Low genetic diversity of the intrinsic OXA-51-like class D carbapenemases among Acinetobacter baumannii clinical isolates in Greece
Ikonomidis, A.; Pournaras, S.; Markogiannakis, A.; Maniatis, A. N.; Manolis, E. N.; Tsakris, A. (2007)This study examined the geographical distribution and diversity of the intrinsic OXA-51-like class D carbapenemases among Acinetobacter baumannii clones recovered in three major Greek regions from 2000 to 2005. The bla(OXA-66) ... -
Molecular cloning and biochemical characterization of VIM-12, a novel hybrid VIM-1/VIM-2 metallo-beta-lactamase from a Klebsiella pneumoniae clinical isolate, reveal atypical substrate specificity
Kontou, M.; Pournaras, S.; Kristo, I.; Ikonomidis, A.; Maniatis, A. N.; Stathopoulos, C. (2007)Metallo-beta-lactamases (MBLs) are considered an emerging family of Zn2+-dependent enzymes that significantly contribute to the resistance of many nosocomial pathogens against beta-lactam antimicrobials. Since these ... -

Methods: ... -
Outbreaks in distinct regions due to a single Klebsiella pneumoniae clone carrying a bla(VIM-1) metallo-beta-lactamase gene
Ikonomidis, A.; Tokatlidou, D.; Kristo, I.; Sofianou, D.; Tsakris, A.; Mantzana, P.; Pournaras, S.; Maniatis, A. N.
