Epidemiological and clinical complexity of amoxicillin-clavulanate-resistant Escherichia coli. J. Clin. Microbiol. 2013 ; 51(7):2414-70095-1137http://hdl.handle.net/10668/1694Journal Article; Research Support, Non-U.S. Gov't;Two hundred twelve patients with colonization/infection due to amoxicillin-clavulanate (AMC)-resistant Escherichia coli were studied. OXA-1- and inhibitor-resistant TEM (IRT)-producing strains were associated with urinary tract infections, while OXA-1 producers and chromosomal AmpC hyperproducers were associated with bacteremic infections. AMC resistance in E. coli is a complex phenomenon with heterogeneous clinical implications.enEscherichia coliInfecciones UrinariasEstudio MulticéntricoInfección HospitalariaAntibacterianosResistencia beta-LactámicaMedical Subject Headings::Named Groups::Persons::Age Groups::AdultMedical Subject Headings::Chemicals and Drugs::Organic Chemicals::Amides::Lactams::beta-Lactams::Clavulanic Acids::Clavulanic Acid::Amoxicillin-Potassium Clavulanate CombinationMedical Subject Headings::Chemicals and Drugs::Chemical Actions and Uses::Pharmacologic Actions::Therapeutic Uses::Anti-Infective Agents::Anti-Bacterial AgentsMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Bacterial Infections::BacteremiaMedical Subject Headings::Named Groups::Persons::Age Groups::ChildMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cross-Sectional StudiesMedical Subject Headings::Organisms::Bacteria::Gram-Negative Bacteria::Gram-Negative Facultatively Anaerobic Rods::Enterobacteriaceae::Escherichia::Escherichia coliMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Bacterial Infections::Gram-Negative Bacterial Infections::Enterobacteriaceae Infections::Escherichia coli InfectionsMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::Middle AgedMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Clinical Trials as Topic::Multicenter Studies as TopicMedical Subject Headings::Diseases::Bacterial Infections and Mycoses::Infection::Urinary Tract InfectionsMedical Subject Headings::Named Groups::Persons::Age Groups::Adult::Young AdultMedical Subject Headings::Phenomena and Processes::Microbiological Phenomena::Bacterial Physiological Phenomena::Drug Resistance, Bacterial::beta-Lactam ResistanceMedical Subject Headings::Named Groups::Persons::Age Groups::Adolescentresearch article23637303open access10.1128/JCM.00999-131098-660XPMC3697715
