| 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 ... | 2010 | 19785534 |
| 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%), ... | 2011 | 21204690 |
