Vibrio parahaemolyticus strain R14

Vibrio parahaemolyticus strain R14 is a Gram-negative, rod-shaped bacterium that thrives in aquatic environments. As a heterotroph, it derives energy from organic compounds and exhibits facultative anaerobic respiration, allowing it to survive in varying oxygen conditions. This strain has a single replicon and is characterized by the presence of two membranes and flagella, which confer mobility. Optimal growth occurs at 20°C, placing Vibrio parahaemolyticus within the mesophilic temperature range. This organism is free-living, engaging in various biotic relationships, and has numerous hosts, including Homo sapiens, Danio rerio, and several marine invertebrates like Ruditapes philippinarum and Penaeus vannamei. Vibrio parahaemolyticus strain R14 is notable for its pathogenic potential in humans, associated with a range of health effects such as ear infections, wound infections, and various gastrointestinal diseases, including vibriosis and gastroenteritis. These health effects highlight the bacterium's role in foodborne illnesses, often linked to the consumption of contaminated seafood. The strain is implicated in acute hepatopancreatic necrosis disease, which affects certain marine species. The ecological significance of Vibrio parahaemolyticus strain R14 lies in its adaptability to aquatic environments and its interactions with both marine organisms and humans. Understanding its pathogenicity and ecological role can inform public health strategies and seafood safety measures, addressing the risks of Vibrio-related infections.
