Comparison of an excision and a sponge sampling method for

The number of salmonella positive excision samples (31 of 312) was significantly higher (P=0 00013) than the number of salmonella positive sponge samples (9 of 312) Sensitivity of the sponge method compared to the excision method was 6 5% and the comparability of both tests was low

Comparison of two sampling and culture systems for

Salmonella enterica was recovered from 14% of samples processed using the electrostatic wipe sampling and culture procedure whereas S enterica was recovered from only 4% of samples processed using the sponge sampling and culture procedure (Table 1) There was test agreement for 85 pairs of culture‐negative samples and 3 pairs of culture

Salmonellosis in Horses

Dec 10 2014Salmonellosis is the most commonly diagnosed infectious cause of diarrhea in adult horses It is an infection of the intestinal tract by a bacterial pathogen called Salmonella named after pathologist Daniel Elmer Salmon (1850-1914) who recognized Salmonella as a

Salmonella enterica: Survival Colonization and Virulence

However a considerable number of outbreaks have been related to crops (Table 3) From 1998 to 2008 fruits and nuts were the highest cause of Salmonella outbreaks in plant products followed by vine stalk vegetables and sprouts Sanderson and Demerec [] reported that Salmonella appears eight times between the top 20 ranked pathogen-food combinations and is most notably associated with poultry

Salmonella's long

Indeed this is often the only site from which viable Salmonella can be recovered Interestingly surgical removal of the MLN results in increased numbers of S Typhimurium bacteria reaching systemic sites early after infection suggesting that the MLN provide a vital barrier shielding systemic compartment dissemination of S

The Salmonella enterica Serotype Typhi Vi Capsular Antigen

Salmonella enterica serotype Typhi the etiological agent of typhoid fever produces the Vi capsular antigen a virulence factor absent in Salmonella enterica serotype Typhimurium Previous studies suggest that the capsule-encoding viaB locus reduces inflammatory responses in intestinal tissue however there are currently no data regarding the in vivo expression of this locus

Title: 3M TM Hydrated

Using a 3M TM Hydrated-Sponge a low level inoculum (approximately 10 colony forming units - CFUs) of the culture strain was added to the sponge and then incubated according the to the DuPont Qualicon BAX and BioMrieux VIDAS assay procedure Media controls were also inoculated and processed in this same manner
