A gram-negative bacterium associated in marine infections particularly in oysters.


Vibrio aestuarianus is an oyster pathogens found in the brackish aquatic environment which maintained viability for a period of time in the sediment indicating that particular niche is suitable for its persistence in the environment.

Vibrio aestuarianus has the capability to form biofilm on poly-vinyl chloride surfaces and has the ability to enter on a viable but non-culturable form after extended incubation at temperature of about 5’C a condition normally found during cold season in the aquatic brackish environment.

Vibrio aestuarianus is implicated in the mortality that strikes the pacific oyster which shows that at first hour of infection is highly pathogenic and obtained basic metabolism, virulence and antibiotic-resistance.
