background : lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. the inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of pseudomonas aeruginosa. the isolates were selected as the most resistant strains when challenged with ant...
background : due to the importance of the metal zinc as an essential biological element with known toxic properties, and considering the widespread secondary infections caused by pseudomonas aeruginosa strains with resistance to antibiotics and disinfectants, the present study aimed at exploring the antimicrobial properties of the metal zinc in both clinical and environmental multiple drug resi...
Abstract Background and Objective: Vancomycin is used for treatment of methicillin-resistant S. Aureus (MRSA) infections therefore, resistance to this antibiotic is increasing. We aimed to determine the antibiotic resistance pattern and frequency of vancomycin resistant S. Areas (VRSA) strains isolated from clinical samples. Material and Methods: In this cross-sectional study, 100 S. Aureus iso...
Abstract Background and Objective: Acinetobacter species are opportunistic important pathogens responsible for many nosocomial infections. The purpose of this study was to determine the drug resistan pattern Acinetobacter baumannii and prevalence of ESBL producing strains in Intensive Care Unit patients in Isfahan city hospitals. Material and Methods: The study was conducted on 100 Ac...
Background: Acinetobacter baumannii is an opportunistic pathogen and a nosocomial infection agent. Antibiotic resistance in this organism results in serious health problem such as treatment failure and increased mortality. Mangrove plants, especially Avicennia marina, are a potential bioresource for new drugs as they have been used in traditional medicine. This study aimed to investigate antib...
Background and Objective: Pseudomonas aeruginosa is the most common pathogen causing nosocomial infections. The aim of this study was to determine the antimicrobial susceptibility pattern and prevalence of ESBLs in clinical and environmental isolates of P. aeruginosa by phenotypic and genotypic techniques. Materials and Methods: In this descriptive study, a total of 100 P. aeruginosa strains is...
Background and Objective: Pseudomonas aeruginosa is an opportunistic pathogen and one of the most frequent pathogens in nosocomial infections. This bacterium shows high resistance to majority of antibiotics including â-lactams. The aim of this study was to investigate the pattern of antimicrobial resistance and evaluation of IMP, SPM and SIM Metallo- Beta- Lactamase producing Pseudomonas aerugi...
Introduction: In the recent decades, the prevalence of Klebsiella pneumoniae beta-lactamase producing strains has a significant role in nosocomial infections. The aim of this study was to determine the prevalence of different types of CTX-M enzymes among clinical isolates of K. pneumoniae. Methods: In this descriptive cross-sectional study, during six months, K. pneumoniae strains were isolate...
Background and purpose: Pseudomonas aeruginosa is an opportunistic pathogen in patients with chronic respiratory disease or in immunocompromised hosts. This bacterium shows intrinsic and acquired resistance to diverse antimicrobial agents. An important mechanism of resistance to fluoroquinolones in P. aeruginosa is the mutation in gyrA, a subunit of topoisomerases II. The aim of this study was ...
results disk diffusion agar showed that 96 strains (48%) were resistant to gentamicin, 89 (44.5%) to ciprofloxacin, 127 (63.5%) to erythromycin, 142 (71%) to tetracycline, 11 (5.5%) to teicoplanin, 32 (16%) to vancomycin, none to linezolid and 96 (48%) to co-trimoxazole. the mics of the resistant isolates were as follows; 88 strains had mic ≥ 32 μg/ml to vancomycin and 59 strains had mic ≥ 32 μ...
