| complete genome sequences of two outbreak strains of salmonella enterica subsp. enterica serovar thompson associated with cilantro. | salmonella enterica subsp. enterica serovar thompson strains rm1984 (cadph-99a2334) and rm1986 (cadph-99a2345) are associated with a 1999 outbreak in contaminated cilantro. we report here the complete genome sequences and annotation of these two s. thompson strains. these genomes are distinct and provide additional data for our understanding of s. enterica. | 2015 | 26586897 |
| complete genome sequence of salmonella enterica subsp. enterica serovar thompson strain rm6836. | salmonella enterica subsp. enterica serovar thompson strain rm6836 was isolated from lettuce in 2002. we report here the complete sequence and annotation of the genome of s. thompson rm6836. this is the first reported complete genome sequence for s. thompson and it will enhance our understanding of this serovar and provide another point for comparative studies between salmonella enterica strains. | 2013 | 24233585 |
| distribution and antimicrobial susceptibility of foodborne salmonella serovars in eight provinces in china from 2007 to 2012 (except 2009). | one thousand four hundred ninety-one salmonella isolates recovered from retail foods including chicken, beef, fish, pork, dumplings, and cold dishes in china in 2007, 2008, 2010, 2011, and 2012 were analyzed for distribution of serotype and antimicrobial susceptibility. a total of 129 salmonella serotypes were detected among 1491 isolates. salmonella enteritidis (21.5%), typhimurium (11.0%), indiana (10.8%), thompson (5.4%), derby (5.1%), agona (3.8%), and shubra (3.0%) were the seven most impor ... | 2017 | 28375673 |
| prevalence of salmonella spp. in packed and unpacked red meat and chicken in south of tehran. | despite of the advances in infectious diseases prevention and food technology, food-borne diseases are considered major problems in developed and developing countries. meat plays a key role in transferring zoonotic diseases to human. | 2014 | 25147699 |
| salmonella thompson splenic abscess in a healthy female. | a 26-year-old woman presented with a 5-day history of fever and 3-day history of left upper quadrant abdominal pain and cough associated with left shoulder tip pain. initial blood cultures did not display growth. on ct imaging, there was a cyst measuring 7.2×8 cm originally interpreted to be haemorrhagic in nature. repeat cultures during admission revealed salmonella thompson. percutaneous drainage and antibiotic treatment, rather than splenectomy, was successfully pursued with the patient afebr ... | 2017 | 28835413 |
| the economic burden of a salmonella thompson outbreak caused by smoked salmon in the netherlands, 2012-2013. | in 2012, the netherlands experienced the most extensive food-related outbreak of salmonella ever recorded. it was caused by smoked salmon contaminated with salmonella thompson during processing. in total, 1149 cases of salmonellosis were laboratory confirmed and reported to rivm. twenty percent of cases was hospitalised and four cases were reported to be fatal. the purpose of this study was to estimate total costs of the salmonella thompson outbreak. | 2017 | 27836967 |
| turtles as a possible reservoir of nontyphoidal salmonella in shanghai, china. | terrapins and turtles are known to transmit salmonella to humans. however, little was known about the occurrence of this pathogen in soft-shelled terrapin that is a popular delicacy in chinese and other east asian cuisines. we isolated and characterized 82 (24.4%) isolates of salmonella from 336 fecal samples of soft-shelled terrapins (51 of 172; 29.7%) and pet turtles (31 of 164; 18.9%) in shanghai. salmonella thompson was the most common serotype (17.1%) among others. many isolates (84.1%) wer ... | 2016 | 27267492 |
