resistance to oxyimino cephalosporins antibiotics in enterobacteriaceae is primarily done by the extended spectrum β-lactamases (esbls). clear identification of risk factors for esbl-producing infections is necessary. therefore, efficient strategies can be developed to decrease outbreak of these infections. the aim of this study was to determine the antibacterial susceptibility and esbls patter...
background & objectives: pseudomonas aeruginosais one of the most important causes of nosocomial infections particularly in immunodeficient patients. several antibiotics such as betalactams, aminoglycosides and quinolones are used for the treatment of infections caused by this organism, but the prevalence of multidrug resistant strains has been reported frequently. beta lactamase production is ...
conclusion prevalence of p. aeruginosa producing esbl and mdr strains from our clinical samples and environment is still low. results the highest resistance rates from the isolated p. aeruginosa were shown against piperacillin, imipenem, cefotaxime, ceftriaxone, gentamicin, ceftazidime, aztreonam, and ciprofloxacin, respectively. seven isolates (9.2%) were esbl producers. more than 30% of the i...
Shigella is a major cause of dysentery across the world. Appropriate antibiotic treatment of shigellosis depends on resistance patterns. The present study was conducted to identify Shigella species and their antibiotic resistance patterns among dysenteric patients in Rezaei Hospital of Damghan. Isolation of Shigella species was conducted by specific culture medium and biochemical tests. The Shi...
conclusions antibiotic resistance gene cassettes may be carried on integron or other genetic elements. the purpose of this study was to detect integron or genomic islands involved in antibiotic resistance profile of the isolates of h. influenzae collected in this study. results of the twenty isolates, all (100%) were resistant to clindamycin, chloramphenicol and tetracycline, 95% to amoxicillin...
conclusions based on our findings, p. aerugionsa is a major causative agent of wound infections and amikacin could be considered as a more effective antibiotic for treatment of the burned patients. background nowadays, the treatment of burned patients is difficult because of the high frequency of infection with antibiotic resistance bacteria. objectives this study was conducted to evaluate the ...
development of antibiotic resistance in intensive care units (icus) is a worldwide problem. the purpose of this study was to evaluate the effect of an antibiotic stewardship program (asp) by carbapenems restriction on gram-negative antimicrobial resistance in icu. the study was designed in a 21 bedded general icu of a teaching hospital with two wings (one and two) in tehran, iran. carbapenem pr...
salmonella is one of the most important zoonotic pathogens with many virulence factors playing a major role in its pathogenesis. the aims of this study were to detect spva, int2 and invc virulence genes of different salmonella serotypes isolated from various clinical animal and human sources, and to investigate antibiotic resistance patterns among these serotypes. using a pcr assay, a total of ...
background: multidrug resistance in salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. methods: salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to pcr and identified as salmonella enteritidis. for detection and identi...
background : acinetobacter baumannii has become one of the most important causes of nosocomial infections in recent years. the organism seems to be resistant to most classes of antibiotics. carbapenems are considered the most effective drugs for treatment of these infections. however, increasing emergence of carbapenem resistant a. baumannii has become a major healthcare problem. methods :...
