BACKGROUND AND OBJECTIVE Carbapenems are therapeutic choice against infections caused by gram-negative bacilli including strains of Acinetobacter baumannii. Resistance to these antibiotics is mediated by efflux pumps, porins, PBPs and ß-lactamases. The aim of this study was to determine the possibility of existence of MBLs, OXAs and GES-1 betalactamase genes among clinical isolates of Acinetoba...
Abstract Background and objectives: (ESBL) strain is one of the emerging health related problems in the world recently. Some of the species of the gram-negative bacilli including Klebsiella Pneumonia & Escherichia Coli are well known ESBL producing among bacteria, and they cause uncontrollable infections. This Cross-sectional study was designed to asses the ESBL producing gra...
Antibiotics are frequently prescribed in the older person, the dosification needs special care, since the pharmacokinetic parameters changes with aging and the side effects can be different in the older person. The creatinine clearance changes and we must modify the way we prescribe such antibiotics to the elderly, calculating. The variety of antibiotics now available led us to consider this pa...
Cepas de Pseudomonas spp. produtoras de metalo-betalactamase isoladas no Hospital Geral de Fortaleza
Pseudomonas aeruginosa genus bacteria are well known for their increased drug resistance (phenotypic ang genotypic resistance). The most important resistance mechanisms are: enzyme production, reduction of pore expression, reduction of the external membrane proteins expression, efflux systems, topoisomerase mutations. These mechanisms often accumulate and lead to multidrug ressitance strains em...
INTRODUCTION Imipenem and meropenem are treatment of choice for extended-spectrum betalactamase (ESBL)-positive gram-negative bacteraemia. They may select for carbapenemresistant Acinetobacter baumannii and Pseudomonas aeruginosa; ertapenem may not do so as it is inactive against these bacteria. Clinical efficacy of ertapenem in ESBL-producing gramnegative bacteraemia is limited. MATERIALS AN...
Background. According to the European Antimicrobial Resistance Surveillance Network, Romania reports an increasing number of resistant Klebsiella pneumoniae strains from invasive infections every year. Material and Method. We analyzed the antimicrobial susceptibility of Klebsiella pneumoniae strains isolated from blood in 2010 and 2015 in "Matei Bals" National Institute of Infectious Diseases, ...
Vol. 7, No. 5, September-October 2001 911 Emerging Infectious Diseases (blaPER-1 and blaVIM-2 ) had been detected separately among clinical isolates, underscores the possibility of the emergence of new threatening combinations of resistance determinants among nosocomial pathogens. In fact, the recruitment of similar resistance determinants within a single P. aeruginosa strain can determine a re...
