Variants of smooth Salmonella enterica serovar Enteritidis that grow to higher cell density than the wild type are more virulent

Article Abstract:

A study was conducted to analyze the isolation of Salmonella enterica serovar Enteritidis that grows to a higher cell density than wild types. Cells were harvested for high-voltage transformation with plasmid pBR322 or pSB402 while fungal cultures were examined using scanning electron microscopy. Results indicated that cell density sensor plasmid pSB402 can be utilized in determining virulent serovar Enteritids.

Production of autoinducer 2 in Salmonella enterica serovar Thompson contributes to its fitness in chickens but not on cilantro leaf surfaces

Article Abstract:

The role of the production of autoinducer 2 (AI-2) in the ability of Salmonella entercia serovar Thompson is investigated to colonize the chicken intestine and the cilantro phyllosphere. A mutant of Salmonella enterica serovar Thompson that is defective in AI-2 production is constructed by insertional mutagenesis of luxS.

Pathogenic role of SEF14, SEF17, and SEF21 fimbriae in Salmonella enterica serovar enteritidis infection of chickens

Article Abstract:

The SEF14, SEF17, and SEF21 fimbriae of Salmonella enterica serovar enteritidis do not appear to be directly involved in adherence to gastrointestinal mucosa, according to a study of mutants. These fimbriae may not be the best target antigens for a Salmonella vaccine.
