Photobacterium damselae subsp. damselae strain KC-Na-1

Photobacterium damselae subsp. damselae strain KC-Na-1 is a Gram-negative bacterium predominantly found in coastal waters, estuaries, oceans, and associated environments such as seaweeds and sediments. This mesophilic organism exhibits mobility, facilitated by the presence of flagella. Notably, it contains five replicons within its genetic structure, which may contribute to its adaptability and survivability in various marine ecosystems. This strain has a broad range of hosts, including Homo sapiens (humans), Pancrustacea (crustaceans), Aves (birds), Mollusca (mollusks), and Cetacea (whales and dolphins), as well as specific species such as Alca torda (razorbill) and Tursiops truncatus (bottlenose dolphin). The diverse host range underscores its ecological versatility and potential impact on marine biodiversity. In terms of health implications, Photobacterium damselae subsp. damselae strain KC-Na-1 has been associated with various infections in humans, including pneumonia, wound infections, necrotizing fasciitis, soft-tissue infections, and chronic suppurative pneumonia. The bacterium can also cause hemorrhagic septicemia and skin lesions, illustrating its pathogenic potential. The presence of this organism in marine environments and its ability to infect various hosts highlight the interconnectedness of marine ecosystems and human health. Understanding Photobacterium damselae subsp. damselae strain KC-Na-1's ecology and pathogenicity is essential for managing health risks associated with marine activities and for preserving marine biodiversity.
