| changing epidemiology of human salmonellosis in hong kong, 1982-93. | a comprehensive analysis of the epidemiology of salmonellosis in a major hospital in hong kong from 1982-93 is reported. the trend of salmonella isolations over the past 12 years and changes in the occurrence of individual serotypes are delineated. a total of 5328 isolates were analyzed. groups b (salmonella typhimurium and s. derby) and e (s. anatum) were the commonest serogroups isolated from the intestinal tract in all age groups. a significant increase in the isolation of group d salmonellae ... | 1994 | 7995352 |
| antimicrobial susceptibilities and molecular epidemiology of salmonella enterica serotype enteritidis strains isolated in hong kong from 1986 to 1996. | the incidence of salmonellosis has been increasing in hong kong since 1989. the most common salmonella enterica serotype isolated in 1994 was s. enteritidis. the antimicrobial susceptibilities and molecular epidemiology of 275 s. enteritidis strains isolated in this locality between 1986 and 1996 were studied. over 99% of the isolates were susceptible to 17 of the 19 antimicrobial agents tested. one isolate harbored an autotransferring plasmid that confers resistance to tetracycline and trimetho ... | 1998 | 9620402 |
| salmonella enterica serotype enteritidis phage types 4, 7, 6, 8, 13a, 29 and 34: a comparative analysis of genomic fingerprints from geographically distant isolates. | to evaluate genetic heterogeneity in the most common phage types of salmonella enterica serovar enteritidis. | 2002 | 11849346 |
| plasmid-mediated resistance to ciprofloxacin and cefotaxime in clinical isolates of salmonella enterica serotype enteritidis in hong kong. | to characterize the genetic determinants involved in the reduced susceptibility to ciprofloxacin and cefotaxime in salmonella enterica serotype enteritidis clinical isolates obtained from four patients in summer 2003 in hong kong. | 2005 | 16033804 |
| ctx-m-producing salmonella spp. in hong kong: an emerging problem. | two salmonella enterica serovar typhimurium isolates and one s. enterica serovar enteritidis isolate that were resistant to 4 microg cefotaxime ml-1 and produced ctx-m-type extended-spectrum beta-lactamases (esbls) were characterized from patients in hong kong during 2003-2004. the s. typhimurium strain isolated in 2003 produced a ctx-m-9 esbl and harboured a blactx-m-9 gene that was associated with a class i integron-containing gene cassette and orf513 similar to those of in60. the second s. ty ... | 2006 | 16914655 |
