Pyomelanin is produced by Shewanella algae BrY and affected by exogenous iron [PDF]
Melanin production by Shewanella algae BrY occurred during late- and (or) post-exponential growth in lactate basal salts liquid medium supplemented with tyrosine or phenylalanine. The antioxidant ascorbate inhibited melanin production but not production of the melanin precursor homogentisic acid.

Searching for putative virulence factors in the genomes of Shewanella indica and Shewanella algae
Archives of Microbiology, 2020Bacterial pathogens are a major threat to both humans and animals worldwide. It is crucial to understand the mechanisms of various disease processes at the molecular level. Shewanella species are widespread in the environment and some are considered as emerging opportunistic human and marine mammal pathogens.

Shewanella algae Causing Pediatric Orbital Abscess With Leptomeningitis
Ophthalmic Plastic & Reconstructive Surgery, 2022A 13-year-old boy presented with 3 days of left-sided periorbital pain, swelling, mucoid discharge, and fever to 103°F, with onset 1 day after swimming in the ocean. Within 12 hours, he experienced rapid clinical deterioration with formation of a superomedial subperiosteal abscess and an epidural abscess with leptomeningitis despite treatment with ...

Pyogenic Flexor Tenosynovitis Caused by Shewanella algae
The Journal of Hand Surgery, 2016Pyogenic flexor tenosynovitis is an orthopedic emergency most commonly caused by Staphylococcus aureus and streptococci and occasionally, when associated with water exposure, Mycobacterium marinum. Shewanella algae, a gram-negative bacillus found in warm saltwater environments, has infrequently been reported to cause serious soft tissue infections and ...

LATE VENTRICULOPERITONEAL SHUNT INFECTION CAUSED BY SHEWANELLA ALGAE
Pediatric Infectious Disease Journal, 2010We present a case of ventriculitis and peritonitis in a child with ventriculoperitoneal shunt, which occurred 5 years after the surgery. The infection developed after contact with seawater and began as otitis. For the first time, Shewanella algae, a marine microorganism, was identified as the cause of ventriculoperitoneal shunt infection.

Regeneration of iron for trichloroethylene reduction by Shewanella alga BrY
Chemosphere, 2007Zero valent iron (ZVI), the primary reactive material in several permeable reactive barriers, is often oxidized to ferrous or ferric iron, resulting in decreased reactivity with time. Iron reducing bacteria can reconvert the ferric iron to its ferrous form, prolonging the reduction of chlorinated organic contaminants. In this study, the reduction of Fe(

Bioreductive deposition of platinum nanoparticles on the bacterium Shewanella algae
Journal of Biotechnology, 2007An environmentally friendly method using the metal ion-reducing bacterium Shewanella algae was proposed to deposit platinum nanoparticles. Resting cells of S. algae were able to reduce aqueous PtCl(6)(2-) ions into elemental platinum at room temperature and neutral pH within 60min when lactate was provided as the electron donor.

Shewanella algae sepsis after bathing in the Baltic Sea
Ugeskrift for LægerShewanella algae is a typical marine bacterium. It is a rare cause of disease in humans, especially in colder sea environments. In this case report, an otherwise healthy elderly male presents with sepsis caused by S. algae a few days after bathing in the Baltic Sea with open wounds from gardening.
