serotypes, antibiotic resistance, and class 1 integrons in salmonella isolates from pediatric cases of enteritis in tehran, iran.the present study was conducted to investigate serotype distribution, antimicrobial resistance patterns, carriage of class 1 integron, and clonality of salmonella strains isolated from patients aged 0-12 years in tehran, iran, during 2007-2008. a total of 139 salmonella isolates were studied. salmonella serotypes enteritidis, infantis, and typhimurium included 84.9% of isolates, enteritidis accounting for 41.7%. the most prevalent resistances were to doxycycline (64.7%), nalidixic acid (61.2%), ...201121204690
characterization of the first extended-spectrum beta-lactamase-producing nontyphoidal salmonella strains isolated in tehran, iran.the infections caused by salmonella remain a significant public health problem throughout the world. beta-lactams and fluoroquinolones are generally used to treat invasive salmonella infections, but emergence and spread of antibiotic-resistant strains are being increasingly notified in many countries. in particular, detection of extended-spectrum beta-lactamases (esbls) in salmonella spp. is a newly emerging threat worldwide. this study was carried out to characterize beta-lactamase-producing sa ...201019785534
high prevalence of integron-mediated resistance in clinical isolates of salmonella enterica.salmonella enterica has become progressively resistant to antimicrobial agents worldwide as a result of genes carried on different classes of integrons. the aim of the current study was to investigate the molecular diversity of these integrons and their association with antimicrobial resistance in clinical s. enterica isolates from tehran, iran. antimicrobial susceptibility testing was performed according to the clinical and laboratory standards institute. the presence of integrons was investiga ...201021099092
