Carbohydrate metabolic systems present on genomic islands are lost and gained in Vibrio parahaemolyticus.

ABSTRACT:

Background

Utilizing unique carbohydrates or utilizing them more efficiently help bacteria expand and colonize new niches. Horizontal gene transfer (HGT) of catabolic systems is a powerful mechanism by which bacteria can acquire new phenotypic traits that can increase survival and fitness in different niches. In this work, we examined carbon catabolism diversity among Vibrio parahaemolyticus, a marine species that is also an important human and fish pathogen.

Results

Phenotypic differences in carbon utilization between Vibrio parahaemolyticus strains lead us to examine genotypic differences in this species and the family Vibrionaceae in general. Bioinformatics analysis showed that the ability to utilize D-galactose was present in all V. parahaemolyticus but at least two dist
