Comparative evaluation of colistin susceptibility testing methods among carbapenem-nonsusceptible Klebsiella pneumoniae and Acinetobacter baumannii clinical isolates
Dafopoulou, K.; Zarkotou, O.; Dimitroulia, E.; Hadjichristodoulou, C.; Gennimata, V.; Pournaras, S.; Tsakris, A. (2015)We compared six colistin susceptibility testing (ST) methods on 61 carbapenem-nonsusceptible Klebsiella pneumoniae (n = 41) and Acinetobacter baumannii (n = 20) clinical isolates with provisionally elevated colistin MICs ... -
Growth Retardation, Reduced Invasiveness, and Impaired Colistin-Mediated Cell Death Associated with Colistin Resistance Development in Acinetobacter baumannii
Pournaras, S.; Poulou, A.; Dafopoulou, K.; Chabane, Y. N.; Kristo, I.; Makris, D.; Hardouin, J.; Cosette, P.; Tsakris, A.; De, E. (2014)Two colistin-susceptible/colistin-resistant (Col(s)/Col(r)) pairs of Acinetobacter baumannii strains assigned to international clone 2, which is prevalent worldwide, were sequentially recovered from two patients after ... -
The Indoleamine 2,3-dioxygenase Inhibitor 1-methyl-tryptophan Suppresses Mitochondrial Function, Induces Aerobic Glycolysis and Decreases Interleukin-10 Production in Human Lymphocytes
Eleftheriadis, T.; Pissas, G.; Karioti, A.; Antoniadi, G.; Liakopoulos, V.; Dafopoulou, K.; Pournaras, S.; Koukoulis, G.; Stefanidis, I. (2012)Background: Indoleamine 2,3-dioxygenase (IDO) suppresses adaptive immunity. It is known that IDO induces T-cell differentiation to regulatory T-cells (Treg) through tryptophan depletion and/or kynurenine pathway products. ... -
Mutations conferring colistin resistance development in Acinetobacter baumannii clinical isolates
Dafopoulou, K.; Poulou, A.; Makris, D.; Hadjichristodoulou, C.; Tsakris, A.; Pournaras, S. (2013)The colistin resistance mechanisms in Acinetobacter baumannii are largely unknown. In the present study, we investigated the characteristics and the mechanisms of colistin resistance in two genetically indistinguishable ... -
Single-Locus-Sequence-Based Typing of bla(OXA-51-like) Genes for Rapid Assignment of Acinetobacter baumannii Clinical Isolates to International Clonal Lineages
Pournaras, S.; Gogou, V.; Giannouli, M.; Dimitroulia, E.; Dafopoulou, K.; Tsakris, A.; Zarrilli, R. (2014)Single-locus bla(OXA-51-like) sequence-based typing (SBT) was evaluated for its ability to determine correctly sequence types (STs) in Acinetobacter baumannii clinical isolates, in comparison with the Pasteur's multilocus ...
