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 ...
Background and Objective: Extensive use of antibiotics in medicine has led to resistance of microorganisms in urinary tract infection (UTI) in both children and adults. Therefore, conducting studies on antibiotic susceptibility is needed for selection of antibiotics based on regional studies. Materials and Methods: During the year 2006 urine samples from all symptomatic patients admitted to...
background antibiotic resistance among staphylococcus aureus is of great concern worldwide. this resistance is further complicated by the ability of s. aureus to confer cross-resistance to other antibiotics due to the presence of resistance genes, such as erythromycin resistance methylase (erm) genes, which render the bacterium resistant to macrolide-lincosamide-streptogramin b (mlsb) antibioti...
Understanding how our use of antimicrobial drugs shapes future levels of drug resistance is crucial. Recently, there has been debate over whether an aggressive (i.e., high dose) or more moderate (i.e., lower dose) treatment of individuals will most limit the emergence and spread of resistant bacteria. In this study, we demonstrate how one can understand and resolve these apparently contradictor...
prevalence of metalo- β-lactamase-producing (mbl) acinetobacter species in a tertiary care hospital.
background and objectives: acinetobacter causes a wide variety of illness in debilitated and hospitalized patients. carbapenem resistance in acinetobacter is an emerging problem and is a cause of concern as many nosocomial infections with acinetobacter are resistant to most other antibiotics. the present study was aimed to study metallo-β-lactamase (mbl) production in acinetobacter species. mat...
Introduction: Acinetobacter baumannii is a major cause of nosocomial infections which affect mainly disabled patients in intensive care units. The bacteria may acquire resistance to antibiotics and hence can seriously endanger antibiotic therapy. The most important problem facing treatment of A. baumannii is increasing reports of resistance to a wide range of antibiotics, including carbapenems,...
background acinetobacter calcoaceticus baumannii (acb) complex are gram-negative opportunistic bacteria with low virulence properties. their resistance to antibiotics has become a matter of concern in hospital infections. objectives the present study aimed to determine the prevalence and antimicrobial susceptibility of acb isolates collected from the nemazee hospital of shiraz. in addition, pul...
