conclusions the results showed that enterococci are common contaminants in food. indeed, this study indicates a high prevalence of multidrug-resistant enterococci in food of animal origin in iran. isolating some persisting enterococcal isolates revealed that continuous surveillance of antimicrobial resistance in enterococci from food is essential. materials and methods thirty samples of meat, c...

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...

The present study was done to evaluate the presence of antibiotic resistance genes in Lactococcus garvieae isolated from cultured rainbow trout, West Iran.The isolates were examined for antimicrobial resistance using disc diffusion method. Of the 24 strains tested, 21 were resistant to ampicillin (87.5%), 9 to erythromycin (37.5%) and 19 to tetracycline (79.1%). Fourteen strains were resistant ...

Objective(s): Acinetobacter baumannii has a high propensity to form biofilm and frequently causes medical device-related infections with multiple-drug-resistance in hospitals. The aim of this work is to study antimicrobial resistance and the role of bap and cpaA genes in biofilm formation by A. baumannii to understand how this pathogen persists in the hospital environment. Materials and Methods...

Background and Objective: As a significant cause of nosocomial infections, Acinetobacter baumannii has been linked to opportunistic infections. The assessment of clonal relatedness of A. baumannii isolates using typing methods like ERIC-PCR is beneficial for controlling conditions due to these resistant isolates. This research aims to study Acinetobacter baumannii resistant isolates to multidru...

Background: Activity of norA efflux pump is one of the antibiotic resistance mechanisms in ciprofloxacin resistant Staphylococcus aureus. In this study, the effect of Artemisia ciniformis extract on reducing the expression of norA efflux pumps gene in ciprofloxacin-resistant Staphylococcus aureus isolates was studied. Materials and Methods: Ciprofloxacin resistant S. aureus isolates, were trea...

Introduction: Pseudomonas aeruginosa is an opportunistic pathogen of clinical importance, particularly in immunocompromised and burn patients. This bacterium is becoming resistant to many antibiotics via intrinsic or acquired mechanisms. Mutations in anti-mutator genes, such as pfpI, can be a potential intrinsic mechanism of antibiotic resistance. This study aimed to evaluate the possible effec...
