Environmental determinants of Vibrio cholerae biofilm development.
Vibrio cholerae is a versatile bacterium that flourishes in diverse environments, including the human intestine, rivers, lakes, estuaries, and the ocean. Surface attachment is believed to be essential for colonization of all of these natural environments. Previous studies have demonstrated that the vps genes, which encode proteins required for exopolysaccharide synthesis and transport, are requ...

متن کاملgenetic determinants differences between vibrio cholerae biotypes
vibrio cholerae o1 are classified into two biotypes, classical and el tor based on susceptibility to bacteriophages and some biochemical properties, each encoding a biotype-specific genetic determinants. before 1961, most epidemics had been caused by the classical biotype. however, with the passage of time, the classical biotype missed from the scenario and the el tor emerged as the major bioty...
متن کاملStringent response regulation of biofilm formation in Vibrio cholerae.
Biofilm formation is a key factor in Vibrio cholerae environmental survival and host colonization. Production of biofilm enables V. cholerae to survive and persist in aquatic environments and aids in the passage through the gastric acid barrier to allow access to the small intestine. The genes involved in biofilm formation are regulated by the transcriptional activators vpsR and vpsT, which are...
متن کاملTemporal quorum-sensing induction regulates Vibrio cholerae biofilm architecture.
Vibrio cholerae, the pathogen that causes cholera, also survives in aqueous reservoirs, probably in the form of biofilms. Quorum sensing negatively regulates V. cholerae biofilm formation through HapR, whose expression is induced at a high cell density. In this study, we show that the concentration of the quorum-sensing signal molecule CAI-1 is higher in biofilms than in planktonic cultures. By...
