(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
