| in vitro probiotic characterization of lactobacillus strains from fermented radish and their anti-adherence activity against enteric pathogens. | in this study, we evaluated the probiotic properties of lactobacillus plantarum, lactobacillus pentosus, and lactobacillus fermentum strains isolated from fermented radish. all the strains survived the simulated oro-gastrointestinal transit condition and showed significantly higher adherence to caco-2 cells compared with the probiotic strain lactobacillus rhamnosus gg. the strains showed broad-spectrum antimicrobial activity, autoaggregation, and coaggregation capacity with pathogens. furthermor ... | 2015 | 26382558 |
| virulotyping of shigella spp. isolated from pediatric patients in tehran, iran. | shigellosis is a considerable infectious disease with high morbidity and mortality among children worldwide. in this survey the prevalence of four important virulence genes including ial, ipah, set1a, and set1b were investigated among shigella strains and the related gene profiles identified in the present investigation, stool specimens were collected from children who were referred to two hospitals in tehran, iran. the samples were collected during 3 years (2008-2010) from children who were sus ... | 2017 | 28218003 |
| shigellosis in nepal: 13 years review of nationwide surveillance. | shigella is a major cause of gastroenteritis especially in children. in developing countries, the incidence is frequent and results are often life threatening. changing epidemiology and emerging antibiotic resistance warrants continuous monitoring of susceptibility. the present study highlights the changing epidemiology and drug resistance patterns of shigella isolated at different hospitals of nepal over a period of 13 years (jan. 2003-dec. 2015). | 2016 | 27814742 |
| the first report of a fully sequenced resistance plasmid from shigella boydii. | the purpose of this study was to characterize mechanisms of plasmid-mediated antimicrobial resistance in shigella boydii. s. boydii strain 2246 with resistance to ciprofloxacin, ceftriaxone and azithromycin was isolated from a human case of watery diarrhea in a chinese public hospital. resistance in strain 2246 to ceftriaxone and azithromycin was attributable to the presence of blactx-m-14, and erm(b) and mph(a), respectively, which were co-located on a multidrug-resistant (mdr) plasmid p2246-ct ... | 2016 | 27766094 |
| a review on sero diversity and antimicrobial resistance patterns of shigella species in africa, asia and south america, 2001-2014. | shigella, gram negative bacterium, is responsible for shigellosis/bacillary dysentery. it is a global concern although it predominates in developing countries. these are shigella dysenteriae, shigella flexneri, shigella boydii and shigella sonnei. drug resistance by shigella species is another headache of the world. therefore; this study aimed to review distribution of shigella serogroups and their antimicrobial patterns carried out in africa, asia and south america. | 2016 | 27576729 |
| molecular characterisation of quinolone-resistant shigella strains isolated in tehran, iran. | over the past few years, the number of shigella strains resistant to nalidixic acid has increased and has made the selection of effective antimicrobial therapy more difficult. the purpose of this study was to investigate the molecular mechanism of quinolone resistance in shigella strains. shigella strains isolated from 1100 diarrhoeal patients in tehran, iran, were assessed for their susceptibility to nalidixic acid prior to pcr-rflp and sequence analysis of their quinolone resistance genes. amo ... | 2016 | 27436462 |
