Pan-drug-resistant (PDR) Acinetobacter baumannii is an important nosocomial pathogen that poses therapeutic challenges. Tigecycline alone or in combination with agents such as colestimethate, imipenem, and/or amikacin is being used clinically to treat PDR A. baumannii infections. The purpose of this study was to compare in vitro susceptibility testing by epsilometric (Etest) methods and the che...
BACKGROUND AND OBJECTIVES Carbapenem resistant Pseudomonas aeruginosa is a serious cause of nosocomial infections. The main purpose of the study is to determine the prevalence rate of imipenem resistant Pseudomonas aeruginosa carrying metallo-ß-lactamase (MBL) genes. MATERIAL AND METHODS 236 Pseudomonas aeruginosa isolates were collected from teaching hospitals of Ahvaz University of Medical ...
Only limited data exist on Pseudomonas aeruginosa ventilator-associated pneumonia (VAP) treated with imipenem, meropenem, or doripenem. Therefore, we conducted a prospective observational study in 169 patients who developed Pseudomonas aeruginosa VAP. Imipenem, meropenem, and doripenem MICs for Pseudomonas aeruginosa isolates were determined using Etests and compared according to the carbapenem...
The lungs of cystic fibrosis (CF) patients are commonly colonized with Pseudomonas aeruginosa biofilms. Chronic endobronchial P. aeruginosa infections are impossible to eradicate with antibiotics, but intensive suppressive antibiotic therapy is essential to maintain the lung function of CF patients. The treatment often includes beta-lactam antibiotics. How these antibiotics influence gene expre...
PURPOSE Combination antibiotic treatment is preferred in nosocomial infections caused by Pseudomonas aeruginosa (P. aeruginosa). In vitro synergism tests were used to choose the combinations which might be used in clinic. The aim of this study was to investigate the synergistic efficacy of synergistic antibiotic combinations in multidrug resistant P. aeruginosa strains. MATERIALS AND METHODS ...
In order to compare the clinical and microbiological efficacies and safety of piperacillin plus tazobactam with those of imipenem plus cilastatin, 134 patients with intra-abdominal infections (73 patients with appendicitis) participated in an open randomized comparative multicenter trial. A total of 40 men and 29 women (mean age, 53 years; age range, 18 to 92 years) were enrolled in the piperac...
The outer membrane permeability to meropenem and imipenem in Escherichia coli K-12 was investigated, and its porin-deficient mutants were transformed with a constructed vector carrying the carbapenem-hydrolyzing CphA metallo-beta-lactamase gene. By using the method of Zimmermann and Rosselet, meropenem was shown to penetrate through the outer membrane of E. coli K-12 five times faster than ceph...
CONTEXT Multiple surveillance programmes have reported a decline in antibiotic susceptibility of P. aeruginosa. AIM Our study aimed to study the relationship between the use of antipseudomonal drugs and the development of resistance of P. aerogenosa to these drugs. SETTING AND DESIGN Our study is retrospective. It was conducted in a medical surgical intensive care unit during a five-year pe...
background: recent analyses of hospital outbreaks have documented the spread of resistance to imipenem, which is currently a major problem among gram positive and gram-negative bacteria. the aim of this study was to describe the rate of gram- positive and gram-negative isolates resistance to imipenem as an antibiotic. methods: recorded files of 242 hospitalized patients with at least one sampl...
Background: Acinetobacter baumannii is one of the causes of nosocomial infections, especially in the intensive care unit. The emergence of multidrug-resistant strains of A. baumannii has caused many problems. One of the ways to handle the phenomenon of antibiotic resistance is the use of herbal medicines and their derivatives in place of or in combination with antibiotics. The aim of this study...
