13. Molecular detection of β-lactamase and integron genes in clinical strains of Klebsiella pneumoniae by multiplex polymerase chain reaction
Abstract INTRODUCTION: Infections caused by β-lactamase-producing gram-negative bacteria, such as Klebsiella pneumoniae, are increasing globally with high morbidity and mortality. The aim of the current study was to determine antimicrobial susceptibility patterns and the prevalence of antibiotic resistance genes (β-lactamase and integron genes) using mul

14. Phenotypic and Genotypic Antibiotic Resistance of Salmonella from Chicken Carcasses Marketed at Ibague, Colombia
ABSTRACT Salmonella enterica is responsible for alimentary toxic infections associated with the consumption of contaminated poultry products and the antimicrobial resistant patterns of Salmonella circulating in the Tolima region are currently unknown. To address this issue, both the phenotype and genotype antibiotic resistance patterns of 47 Salmonella isola

16. Detection and molecular characterization of β-lactamase genes in clinical isolates of Gram-negative bacteria in Southern Ecuador
ABSTRACT This work performed a phenotypic and genotypic characterization of 79 clinical isolates of Enterobacteriaceae and Pseudomonadaceae collected in hospitals of Southern Ecuadorin 2013. Our results showed a high incidence of β-lactamases and ESBLs with blaTEM and blaCTX-M as the prevalent genes, respectively. By direct sequencing of PCR amplicons, the

18. Detecção de genes de resistência a antimicrobianos em Klebsiella pneumoniae produtoras de betalactamases e carbapenemases por culturas de vigilância de pacientes em uma unidade de terapia intensiva no Rio de Janeiro, Brasil
RESUMO Introdução: O aumento da incidência de microrganismos multirresistentes é considerado um dos principais problemas de saúde pública. Uma das rotinas incluídas na prática hospitalar é a busca de pacientes colonizados e/ou infectados. Objetivo: Avaliar a variabilidade genética e as relações clonais de K. pneumoniae produtoras de betalactama

19. First report of TEM-104-, SHV-99-, SHV-108-, and SHV-110-producing Klebsiella pneumoniae from Iran
Abstract: INTRODUCTION: Extended-spectrum beta-lactamases (ESBLs) are bacterial enzymes capable of hydrolyzing beta-lactams. The aim of this study was to describe the prevalence of TEM- and SHV-type ESBL-producing Klebsiella pneumoniae strains in Zahedan, Southeast Iran. METHODS: A total of 170 non-repetitive K. pneumoniae strains were collected from patie

20. Occurrence and characteristics of extended spectrum beta-lactamases-producing Enterobacteriaceae from foods of animal origin
Abstract Presence of extended spectrum beta-lactamases (ESBL) in bacteria is a growing health concern of global significance. The local, regional, national, and international epidemiological studies for extended spectrum beta-lactamases-producing Enterobacteriaceae and their encoding genes in foods are still incomplete. The objective of this study was to det

21. Detection of cfxA2, cfxA3, and cfxA6 genes in beta-lactamase producing oral anaerobes
ABSTRACT Purpose The aim of this study was to identify β-lactamase-producing oral anaerobic bacteria and screen them for the presence of cfxA and BlaTEM genes that are responsible for β-lactamase production and resistance to β-lactam antibiotics. Material and Methods Periodontal pocket debris samples were collected from 48 patients with chronic period

22. Resistance patterns, ESBL genes, and genetic relatedness of Escherichia coli from dogs and owners
Abstract Antimicrobial resistance in Escherichia coli isolated from pet dogs can be considered a potential threat of infection for the human population. Our objective was to characterize the resistance pattern, extended spectrum beta-lactamase production and genetic relatedness of multiresistant E. coli strains isolated from dogs (n = 134), their owners (n =

24. Primeira detecção de metalobetalactamases em isolados nosocomiais de Pseudomonas aeruginosa em Alagoas, Brasil
RESUMOIntrodução:Pseudomonas aeruginosa é a principal causa de infecções oportunistas em seres humanos, e a escolha de agentes antimicrobianos eficazes para controlar essa bactéria tem sido limitada, principalmente devido à sua capacidade de produzir metalobetalactamases (MβL), enzimas capazes de inativar muitos antimicrobianos por meio de hidrólise
