| clonal diversity of salmonella enterica serotype typhi isolated from patients with typhoid fever in tehran. | in this study, antimicrobial susceptibility test and genetic typing were used to characterize 15 salmonella enterica serotype typhi (s. typhi) isolates recovered from sporadic cases of typhoid fever in tehran, iran during 2004. antimicrobial susceptibility test showed that all isolates were susceptible to 20 antimicrobials examined in this study. analysis of insertion elements showed that 2 is200 types with 10 and 11 copies were present. 11 of the 15 isolates were found to possess 10 is200 eleme ... | 2008 | 17852914 |
| phylogenetic relationship of salmonella enterica strains in tehran, iran, using 16s rrna and gyrb gene sequences. | we assessed whether 16s rdna and gyrb gene sequences, alone or combined, were suitable for determining the phylogenetic relationship among salmonella enterica strains isolated from tehran, iran. patients over five years of age enrolled in an acute diarrheal surveillance project in tehran province between may 2004 and october 2006 were selected as our study group. | 2011 | 21727646 |
| 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 ... | 2010 | 21099092 |
| 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 |
| emergence of extended-spectrum beta-lactamases in clinical isolates of salmonella enterica in tehran, iran. | the purpose of the current study was to investigate the presence and molecular type(s) of extended-spectrum beta-lactamases (esbls) in salmonella spp. isolates obtained from patients with diarrhea in hospitals of tehran, iran. over a period of 17 months, 129 salmonella spp. were isolated from fecal samples and tested for susceptibility using the kirby-bauer disk diffusion method; then, screening for esbl-producing isolates and determination of their minimum inhibitory concentrations were carried ... | 2009 | 19762986 |
| isolasion, identification and antimicrobial resistance patterns of salmonella from meat products in tehran. | the present study was carried out from 400 samples in different slaughterhouses to report the isolation along with the serotypes and antibiogram pattern of salmonella among products in tehran. salmonella was isolated from samples of chicken, beef; veal, mutton, roast beef and sausage fermentive meat collected at slaughterhouses. the isolates were characterized by serotyping and antimicrobial-susceptibility testing. eighty isolates of salmonella enterica belonging to 19 serotypes--s. adelaide, s. ... | 2007 | 19069997 |
| genetic diversity and virulence genes of salmonella enterica subspecies enterica serotype enteritidis isolated from meats and eggs. | salmonella enterica subspecies enterica serotype enteritidis (s. enteritidis) is one of the leading causes of food-borne gastroenteritis associated with the consumption of contaminated food products of animal origin. little is known about the genetic diversity and virulence content of s. enteritidis isolated from poultry meats and eggs in iran. a total of 34 s. enteritidis strains were collected from different food sources of animal origin in tehran from may 2015 to july 2016. all of the s. ente ... | 2017 | 28433796 |
| multiple-locus variable-number tandem repeat analysis (mlva) for genotyping of salmonella enterica subspecies enterica serotype infantis isolated from human sources. | salmonella is an important cause of food-borne infection worldwide. detection of outbreaks caused by salmonella spp. relies on suitable and robust methods for genotyping. little is known about the genetic diversity of the salmonella enterica subspecies enterica serotype infantis strains isolated from human sources in iran. in this study, 40 isolates of s. infantis, which were previously recovered from patients with gastroenteritis or diarrhea in tehran between years 2007 and 2009, were subjected ... | 2016 | 27765620 |
