Salmonella enterica serovar Typhimurium DT104 displays a rugose phenotype

Article Abstract:

Research has been conducted on the rugose phenotype. The identification of this phenotype in Salmonella enterica serovar Typhimurium DT104 has been carried out, and the results indicate that it enhances its survival under unfavorable conditions.

Capsular polysaccaride surrounds smooth and rugose types of Salmonella enterica serovar Typhimurium DT104

Article Abstract:

The constitutive synthesis of a capsular polysaccaride that surrounds the cell and is also a component of serovar Typhimurium DT104 biofilms, functioning in a way other than as a primary adhesin is presented. Results reveal that a constitutively produced capsule is an integral component of the exopolymeric substances and biofilm produced by serovar Typhimurium DT104 at 37 degree Celsius.

Alteration of the rugose phenotype in waaG and ddhC mutants of Salmonella enterica serovar Typhimurium DT104 is associated with inverse production of curli and cellulose

Article Abstract:

A description on the effects on rugose formation by transposon insertion in two genes of Salmonella enterica over Typhimurium DT104 that alter lipopolysaccharide (LPS) formation, ddhC and waaG is presented. The changes in LPS independently retarded the appearance of the rugose phenotype mainly due to modifications in the synthesis of both curli and cellulose.
