Photobacterium damselae subsp. damselae strain JM-2017 EQ875_137

Photobacterium damselae subsp. damselae strain JM-2017 EQ875_137 is a Gram-negative bacterium found in diverse marine environments, including coastal waters, estuaries, and sediments, often associated with seaweeds. This mesophilic organism exhibits mobility, facilitated by the presence of flagella. Genetic analysis indicates that it contains one replicon. This strain is known to infect a variety of hosts, including Homo sapiens, Pancrustacea, Aves, Mollusca, and Cetacea, with specific species such as Alca torda and Tursiops truncatus being noted. In humans, infections caused by this bacterium can lead to serious health issues, including pneumonia, wound infections, necrotizing fasciitis, and skin lesions. It is also associated with hemorrhagic septicemia and chronic suppurative pneumonia, indicating its potential as a significant pathogen in marine and terrestrial ecosystems. The presence of Photobacterium damselae subsp. damselae in various habitats underscores its ecological versatility and its role as a pathogen across different species. Understanding its distribution in marine environments and its pathogenic effects on both wildlife and humans highlights the importance of monitoring this bacterium, particularly in coastal regions where human activities may influence its prevalence and impact.
