Vibrio parahaemolyticus strain HS-22-14

Vibrio parahaemolyticus strain HS-22-14 is a Gram-negative, rod-shaped bacterium that thrives in aquatic environments as a heterotrophic, facultative anaerobe. This organism is motile, possessing flagella, and typically exists as single cells. It exhibits mesophilic characteristics, with an optimal growth temperature of 20°C, allowing it to flourish in a range of temperatures suitable for marine environments. Strain HS-22-14 has a single replicon and is characterized by a double-membrane structure, typical of many Gram-negative bacteria. It is a free-living organism but has been associated with various hosts, including Homo sapiens, Danio rerio, various crustaceans (Pancrustacea), bivalves (Ruditapes philippinarum, Keenocardium californiense, Ostreidae), and other marine organisms like Penaeus vannamei and Holothuroidea. This strain is known for its pathogenic potential in humans, being linked to a variety of health issues such as ear infections, wound infections, gastroenteritis, vibriosis, and other foodborne diseases. The presence of V. parahaemolyticus in seafood can lead to significant public health concerns, including acute gastroenteritis and systemic sepsis. Biologically, the adaptability of strain HS-22-14 to both aquatic habitats and different host organisms illustrates its ecological versatility. Its role in foodborne illnesses emphasizes the importance of monitoring and controlling pathogenic Vibrio species in marine food sources to safeguard human health.
