| [evolution of the molecular characterization profile of salmonellosis: the experience of sardinia, italy, 1994-2009]. | the epidemiology of salmonellosis in italy has clearly changed over the years. the circulation of human-specific genotypes has diminished while there has been an increase in genotypes of animal origin. in the years 1994-2009, 3727 salmonella genotypes were isolated and/or genotyped in sardinia (italy). the most frequent serotypes were salmonella enteritidis (29%) and salmonella typhimurium (25,7%). if we consider the years 2000-2009, 6.4% of isolated genotypes were found to be salmonellae with t ... | 2011 | 21468150 |
| clonal relations among salmonella enteritidis phage type 3 outbreak isolates traced by dna fingerprinting. | isolates of salmonella enteritidis pt3, a rare phage type, were recovered from patients and strains were isolated from an outbreak of gastroenteritis that occurred during the summer of 1997 in north-east sardinia, italy. to investigate possible clonal involvement in the outbreak and to evaluate the capacity to discriminate among s. enteritidis pt3 strains, a number of molecular typing methods including ribotyping with a mixture of psti and sphi (ps-ribotyping), pfge with endonuclease xbai and ra ... | 2001 | 11718375 |
