Induction of fatty acid composition modifications and tolerance to biocides in Salmonella enterica serovar Typhimurium by plant-derived terpenes.

abstract：:The cholera toxin genes of Vibrio cholerae are encoded by CTXΦ, a lysogenic bacteriophage. Infection with this phage plays a determinant role in toxigenicity conversion and the emergence of new clones of pathogenic V. cholerae. Multiple phage alleles, defined by sequence types of the repressor gene rstR, have been fou...
