Research Progress on Virulence Factors ofVibrio alginolyticus: A Key Pathogenic Bacteria of Sepsis

Abstract

As an opportunistic pathogen, V. alginolyticus is commonly found in people with weak immune systems or open wounds. The history of seafood exposure is a major feature of V. alginolyticus infection. V. alginolyticus can infect marine economic animals such as fish, shrimp, and shellfish, and is also one of the key pathogens that cause sepsis in human. Because of its rapid progress and extremely high mortality after the infection, it has received more and more attention in clinical practice. At present, there is no effective method to completely control the incidence of V. alginolyticus. Therefore, it is particularly important to study the virulence factors and pathogenic mechanisms of V. alginolyticus. This article reviews recent studies on virulence factors of V. alginolyticus, such as quorum sensing, virulence proteins, ferroportin hemolysin, flagella, lipopolysaccharide system and biofilm formation, with the hope of providing further insights into aquaculture and public health.

Occurrence of Potentially Pathogenic Bacteria in Commercially Sold Seafood from Misamis Occidental, Philippines

“…This bacterium is one of the most popular Vibrio species occurring in marine environments and seafood (Neetoo et al 2022). V. alginolyticus is an opportunistic pathogen, and its pathogenicity is thought to be similar to that of V. parahaemolyticus [42]. In India and Taiwan, this Vibrio species is linked with a white spot in shrimp while the zoonotic risk of this pathogen has been implicated in soft tissue, wound and ear infections in humans [43].…”
