Antimicrobial resistance in Enterobacteriaceae in Brazil: focus on β-lactams and polymyxins
During the last 30 years there has been a dissemination of plasmid-mediated β-lactamases in Enterobacteriaceae in Brazil. Extended spectrum β-lactamases (ESBL) are widely disseminated in the hospital setting and are detected in a lower frequency in the community setting. Cefotaximases are the most frequently detected ESBL type and Klebsiella pneumoniae is the predominant species among ESBL prod...
متن کاملOutbreak of carbapenem-resistant Klebsiella pneumoniae: two-year epidemiologic follow-up in a tertiary hospital
This study describes a carbapenem-resistant Klebsiella pneumoniae (CRKP) outbreak that occurred from October 2008-December 2010. Polymerase chain reaction assays were performed to detect the blaKPC gene and molecular typing was performed using pulsed-field gel electrophoresis (PFGE). There were 33 CRKP infections; PFGE revealed five genotypes: genotype A in five (15%), B in 18 (55%), C in eight...
متن کاملMolecular Mechanisms of Colistin Resistance in Klebsiella pneumoniae Causing Bacteremia from India—A First Report
Colistin has long been a reserve drug used for the treatment of carbapenem resistant Klebsiella pneumoniae. Carbapenem resistance in K. pneumoniae has been increasing and is as high as 44% in India. Although a reserve agent, with rise in rates of resistance to carbapenems, the usage of colistin has increased over the years leading to slow emergence of resistance. Colistin resistance is mainly m...
متن کاملCarbapenem-resistant GES-5-producing Klebsiella pneumoniae in Southern Brazil.
GES-type enzymes belong to Ambler Class A plasmidencoded -lactamases. Although GES enzymes usually exhibit extended-spectrum -lactamases (ESBL) properties, changes in its active site enhance its activity conferring the ability to hydrolyze carbapenems.1 GES-type carbapenemases (GES2, GES-4, GES-5, GES-8, GES-11, GES-18, GES-20) have already been described in several countries.2 Although it has ...
