Microalgae species as potential inhibitors of the bioactivity of Vibrio parahaemolyticus in shrimps

Abstract

Vibrio parahaemolyticus is a Gram-negative motile bacteria belonging to Vibrionaceae family causing cytotoxicity in cultured cells and enterotoxicity in animal models. Similarly, this bacterium is a major foodborne pathogen that causes life-threatening diseases in human, including gastroenteritis and septicemia, via consumption of contaminated seafood. Based on the increasing interest in developing novel environmental friendly solutions for the inhibition of the bioactivity of V. parahaemolyticus, microalgae species have emerged as potential candidates due to the microbiota associated with microalgae cultures, oxygen radicals produced during the photosynthetic process and the production of secondary metabolites, useful for antibacterial properties. In the present review, conventional treatments concerning V. parahaemolyticus bioactivity have been presented. However, in terms of effectiveness, numerous studies explaining the use of microalgae species for antibacterial activity against V. parahaemolyticus have been detailed suggesting that microalgae-based treatment are considerably better. Finally, we presented a proposed microalgae-based solution that can act as an inhibitor of V. parahaemolyticus bioactivity and therefore can be applied in the aquaculture industrial field to improve productivity and reduce costs.
