Secreted Citrate Serves as Iron Carrier for the Marine Pathogen Photobacterium damselae subsp damselae
Photobacterium damselae subsp damselae (Pdd) is a Vibrionaceae that has a wide pathogenic potential against many marine animals and also against humans. Some strains of this bacterium acquire iron through the siderophore vibrioferrin. However, there are virulent strains that do not produce vibrioferrin, but they still give a strong positive reaction in the CAS test for siderophore production. I...
متن کاملPhotobacterium damselae subsp. damselae, an Emerging Pathogen Affecting New Cultured Marine Fish Species in Southern Spain
Aquaculture is the fastest growing food-producing sector, accounting almost 50% of the world food fish demand. Considering the projected population growth over the next two decades, it is estimated that at least an additional 40 million tonnes of aquatic food will be required by 2030 to maintain the current per capita consumption (NACA/FAO, 2001). Marine aquaculture production was 30.2 million ...
متن کاملPhenotypic characterization of the marine pathogen Photobacterium damselae subsp. piscicida.
The taxonomic position of Photobacterium damselae subsp. piscicida, the causative agent of fish pasteurellosis, is controversial as this organism has also been described as 'Pasteurella piscicida'. To clarify the taxonomic position of the pathogen, a total of 113 P. damselae subsp. piscicida strains and 20 P. damselae subsp. damselae strains, isolated from different geographical areas and from ...
متن کاملPhotobacterium damselae subsp. damselae, a bacterium pathogenic for marine animals and humans
Photobacterium damselae subsp. damselae (formerly Vibrio damsela) is a pathogen of a variety of marine animals including fish, crustaceans, molluscs, and cetaceans. In humans, it can cause opportunistic infections that may evolve into necrotizing fasciitis with fatal outcome. Although the genetic basis of virulence in this bacterium is not completely elucidated, recent findings demonstrate that...
متن کاملrstB Regulates Expression of the Photobacterium damselae subsp. damselae Major Virulence Factors Damselysin, Phobalysin P and Phobalysin C
The marine pathogenic bacterium Photobacterium damselae subsp. damselae causes septicemia in marine animals and in humans. The pPHDD1 plasmid-encoded hemolysins damselysin (Dly) and phobalysin P (PhlyP), and the chromosome-encoded hemolysin phobalysin C (PhlyC) constitute its main virulence factors. However, the mechanisms by which expression of these three hemolysins is regulated remain unknow...
