Background and Objective Widespread use of co-trimoxazole in urinary tract infection treatments and its incorrect use has led to the emergence of co-trimoxazole resistant E. coli strains. The aim of this study was to evaluate sul2 gene among E.coli isolates of patients admitted to the clinical centers of Khoy city. Materials and Methods: Three hundred urine samples were collected from clinic...
Background & Aims: Nowadays, the common use of azoles has led to increased resistance to azole among Candida albicans strains. Amino acid substitutions in azole target enzyme, ERG11p, is attributed to azole resistance in some clinical strains of Candida albicans. The aim of this study was to evaluate ERG11 gene mutations in fluconazole-resistant isolates of Candida albicans in Rasht. Materials...
Background & Objective: Klebsiella pneumoniae has received attention due to a wide range of diseases and antibiotic resistance.The resistance to fluoroquinolones in gram-negative bacteria is often due to chromosomal mutations in the gyr and par genes. This research aimed at investigating the pattern of fluoroquinolone resistance and its relation with a mutation in the parC gene among clinical i...
Objective(s): The aim of the present study was to determine the aminoglycoside modifying enzymes (AMEs) encoded genes, tetracycline resistance genes, and the coa based typing of Staphylococcus aureus isolates in the Southwest of Iran. Materials and Methods: Antimicrobial susceptibility of isolates was carried out by agar disk diffusion methods. Two sets of multiplex PCR mixture were used for de...
The aim of this study was to isolate, identify and determine the antimicrobial susceptibility of Clostridium perfringens (CP) isolates from acute necrotic enteritis of broiler chickens. All broiler carcasses diagnosed as necrotic enteritis (NE) were sampled, subjected to microbial tests and 40 isolates were identified according to standard procedures. The antimicrobial susceptibility of CP isol...
Introduction: Greatly increased use of antifungal therapies has resulted in the development of multidrug resistant. The phenolic compound carvacrol have been reported to have anti-Candida activity. This work is an attempt to examine effect of carvacrol on ergosterol synthesis against multidrug resistant Candida albicans. Methods: This cross-sectional study has been conducted on 30 immune-compr...
Background and Objective: Efflux pump inhibitors (EPIs) can block efflux pumps and are helpful in potentiating the activity of aminoglycosides against Pseudomonas aeruginosa. The present study compared the effects of phenylalanine-arginine beta naphthylamide (PAβN) and curcumin on aminoglycoside minimum inhibitory concentration (MIC) on Pseudomonas aeruginosa clinical isolates. Materials and M...
Background & Aims: Staphylococcus aureus is a Gram-positive coccus that can cause a range of infections. Methicillin resistance in these bacteria is often in companion with resistance to multiple antibiotics. High prevalence of these isolates can cause treatment failure. Phosphomycin is a Peptidoglycan biosynthesis inhibitor that is used in treating of infections caused by multi-drug resistant...
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- beta- lactamase (mbl) genes. material and methods : 236 pseudomonas aeruginosa isolates were collected from teaching hospitals of ahvaz university of me...
background plasmid-mediated quinolone resistance genes (pmqr) have been shown to play not only an important role in quinolone resistance, but also resistance to other antibiotics, particularly β-lactams and aminoglycosides. these genes are mainly associated with clinical isolates of enterobacteriaceae. however, detection of pmqr genes in the community isolates can increase the dissemination rat...
