Antimicrobial susceptibility of Neisseria gonorrhoeae in Greece: data for the years 1994-2004
Stathi, M.; Flemetakis, A.; Miriagou, V.; Avgerinou, H.; Kyriakis, K. P.; Maniatis, A. N.; Tzelepi, E. (2006)Objectives: Surveillance data concerning antimicrobial susceptibilities of Neisseria gonorrhoeae isolated in Greece during the 11 year period 1994-2004 are presented. Methods: Antimicrobial susceptibilities of all gonococcal ... -
Characterization of Metallo-beta-Lactamase VIM-27, an A57S Mutant of VIM-1 Associated with Klebsiella pneumoniae ST147
Papagiannitsis, C. C.; Kotsakis, S. D.; Petinaki, E.; Vatopoulos, A. C.; Tzelepi, E.; Miriagou, V.; Tzouvelekis, L. S. (2011)VIM-27 metallo-beta-lactamase, an Ala(57) -> Ser variant of VIM-1, was identified in three Klebsiella pneumoniae isolates belonging to sequence type 147. bla(VIM-27) was part of a class 1 integron carried by non-self-transferable ... -
Ciprofloxacin-resistant Escherichia coli in Central Greece: mechanisms of resistance and molecular identification
Mavroidi, A.; Miriagou, V.; Liakopoulos, A.; Tzelepi, E.; Stefos, A.; Dalekos, G. N.; Petinaki, E. (2012)Background: Fluoroquinolone resistant E. coli isolates, that are also resistant to other classes of antibiotics, is a significant challenge to antibiotic treatment and infection control policies. In Central Greece a ... -
Effects of the Val211Gly substitution on molecular dynamics of the CMY-2 cephalosporinase: Implications on hydrolysis of expanded-spectrum cephalosporins
Kotsakis, S. D.; Tzouvelekis, L. S.; Petinaki, E.; Tzelepi, E.; Miriagou, V. (2011)CMY-30, a naturally occurring class C beta-lactamase differing from the Citrobacter freundii-derived CMY-2 by a Val211Gly substitution in the X-loop, exhibits increased hydrolytic efficiency against ceftazidime and cefotaxime. ... -
Emergence and maintenance of multidrug-resistant Escherichia coli of canine origin harbouring a bla(CMY-2)-IncI1/ST65 plasmid and topoisomerase mutations
Vingopoulou, E. I.; Siarkou, V. I.; Batzias, G.; Kaltsogianni, F.; Sianou, E.; Tzavaras, I.; Koutinas, A.; Saridomichelakis, M. N.; Sofianou, D.; Tzelepi, E.; Miriagou, V. (2014)To characterize the mechanisms implicated in fluoroquinolone (FQ) and expanded-spectrum cephalosporin (ESC) resistance in three clinical and seven faecal multidrug-resistant (MDR; resistant to at least three antimicrobial ... -
Outbreak of infections caused by Enterobacter cloacae producing the integron-associated beta-lactamase IBC-1 in a neonatal intensive care unit of a Greek hospital
Kartali, G.; Tzelepi, E.; Pournaras, S.; Kontopoulou, C.; Kontos, F.; Sofianou, D.; Maniatis, A. N.; Tsakris, A. (2002)Nineteen of 27 ceftazidime-resistant Enterobacter cloacae isolates from a neonatal intensive care unit in Thessaloniki, Greece, had genes coding for the novel extended-spectrum beta-lactamase IBC-1; 18 of those 19 harbored ...
