Klebsiella pneumoniae strains producing extended-spectrum beta-lactamases in Spain: microbiological and clinical features. J. Clin. Microbiol.. 2011 Mar; 49(3):1134-6http://hdl.handle.net/10668/2080Journal Article; Multicenter Study; Research Support, Non-U.S. Gov't;Extended-spectrum β-lactamases (ESBL) of the CTX-M, SHV, and TEM families were recognized in 76 (67%), 31 (27%), and 6 (5%) isolates, respectively, among 162 ESBL-producing Klebsiella pneumoniae (ESBL-Kp) strains obtained in a multicenter study in Spain. Predisposing factors for ESBL-Kp acquisition included invasive procedures, mechanical ventilation, and previous antimicrobial use.enAntibacterianosRecién nacidoInfecciones por klebsiellaMedical Subject Headings::Chemicals and Drugs::Chemical Actions and Uses::Pharmacologic Actions::Therapeutic Uses::Anti-Infective Agents::Anti-Bacterial AgentsMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Named Groups::Persons::Age Groups::Infant::Infant, NewbornMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Bacterial Infections::Gram-Negative Bacterial Infections::Enterobacteriaceae Infections::Klebsiella InfectionsMedical Subject Headings::Organisms::Bacteria::Gram-Negative Bacteria::Gram-Negative Facultatively Anaerobic Rods::Enterobacteriaceae::Klebsiella::Klebsiella pneumoniaeMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Clinical Laboratory Techniques::Microbiological Techniques::Microbial Sensitivity TestsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::Vital Statistics::Morbidity::PrevalenceMedical Subject Headings::Geographicals::Geographic Locations::Europe::SpainMedical Subject Headings::Chemicals and Drugs::Enzymes and Coenzymes::Enzymes::Hydrolases::Amidohydrolases::beta-LactamasesMedical Subject Headings::Named Groups::Persons::Age Groups::Adultresearch article21191059open access10.1128/JCM.02514-101098-660X
