| serological characterization and prevalence of spvr genes in salmonella isolated from foods involved in outbreaks in brazil. | salmonella strains (n = 75) isolated from foods involved in foodborne outbreaks occurred in rio grande do sul state, brazil, during 1999 and 2000 were studied. strains were serotyped and submitted to pcr analysis to verify the prevalence of salmonella plasmid virulence (spvr) regulatory gene. among the 75 isolates, 73 (97%) were classified as salmonella enterica serovar enteritidis. all of the salmonella strains isolated in 1999 were classified as serotype enteritidis, whereas in 2000 two isolat ... | 2004 | 15222555 |
| investigation of rpos and dps genes in sodium hypochlorite resistance of salmonella enteritidis se86 isolated from foodborne illness outbreaks in southern brazil. | in rio grande do sul, southern brazil, salmonella enteritidis is one of the principal microorganisms responsible for foodborne disease. the present study was conducted to compare the sodium hypochlorite resistance of salmonella enteritidis se86 with that of other strains of salmonella enteritidis isolated from different regions of the world and to investigate the involvement of the rpos and dps genes in resistance to this disinfectant. we tested five salmonella enteritidis wild-type (wt) strains ... | 2012 | 22410215 |
| modeling growth kinetic parameters of salmonella enteritidis se86 on homemade mayonnaise under isothermal and nonisothermal conditions. | during the last decade, a specific strain of salmonella enteritidis (named se86) has been identified as the major etiological agent responsible for salmonellosis in the state of rio grande do sul, southern brazil, and the main food vehicle was homemade mayonnaise (hm). this study aimed to model the growth prediction of se86 on hm under isothermal and nonisothermal conditions. se86 was inoculated on hm and stored at 7, 10, 15, 20, 25, 30, and 37°c. growth curves were built by fitting data to the ... | 2016 | 26859536 |
