conclusions the high prevalence of quinolone resistance genes, which indicates antibiotic resistance, in the imam reza hospital of mashhad is a major concern. hence, the antibiotics prescription policy should be revised, and infection control measures should be improved. results eighty-six (43%) isolates were ciprofloxacin-resistant. the pct identified 85 (42.5%) of 200 e. coli isolates as esbl...

During the last three decades the chemistry of allenes has fascinated scientists worldwide. Thus, its beauty has been recognized in a diversity of allenic natural products, many of them showing interesting or promising therapeutic activities. In fact, around 150 natural products containing an allenic or cumulenic structure have been identified. In the meantime, the reactivity of allenes has bee...

conclusions our data showed that, the high prevalence of beta-lactamase genes among isolates, and it. our findings may provide useful insights in replace of the appropriate antibiotics and it may also prevents of esbls, mediated resistance problem. results from 145 strains of e. coli, 51(35.2%) and 61(42.1%) isolates were resistance to ceftazidime and cefotaxime, respectively. esbl production w...

BACKGROUND Carbapenem resistant Acinetobacter baumannii is an important nosocomial pathogen associated with a variety of infections. OBJECTIVES The current study aimed to characterize the antimicrobial susceptibility, analyze the prevalence of oxacillinase and metallo-β-lactamase (MBL) genes and molecular typing of clinical isolates of A. baumannii. MATERIALS AND METHODS A total of 124 non-...

conclusions the rate of carbapenem resistant a. baumannii isolates were high in this study. since, blaoxa-58-like or mbl genes were not detected, it seems that resistance to carbapenems is related to blaoxa-23-like and blaoxa-24-like. moreover, blaoxa-23-like was the most prevalent oxacillinase (oxa) gene. most of the isolates belonged to one of the four dominant genotypes indicating clonal dis...
