Vibrio alginolyticus strain ATCC 33787

Vibrio alginolyticus strain ATCC 33787 is a Gram-negative, facultative anaerobic bacterium predominantly found in marine environments. This organism is characterized by its motility, facilitated by the presence of flagella, and it thrives optimally at a temperature of approximately 30°C. Vibrio alginolyticus is notable for its role in various health-related issues, particularly in humans and marine species. In humans, it can cause conditions such as septicaemia, vibriosis, and gastroenteritis, which are often associated with the consumption of contaminated seafood. In addition to affecting humans, this strain poses significant risks to aquaculture, causing diseases in hosts such as Sparus aurata (sea bream), various Mollusca species, and Penaeus vannamei (Pacific white shrimp). Key health effects observed in these hosts include skin and muscle necrosis, leading to severe impacts on fish and shellfish populations. The strain is genetically diverse, with five distinct replicons documented, indicating a complex genomic structure that may contribute to its adaptability and virulence. The presence of multiple accessions (NZ_CP013485.1; NZ_CP013487.1; NZ_CP013488.1; NZ_CP013484.1; NZ_CP013486.1) suggests an ongoing interest in the genetic characterization of this pathogen. Understanding the ecological role of Vibrio alginolyticus in marine ecosystems is crucial, as its pathogenic potential poses challenges not only to public health but also to the sustainability of marine aquaculture.
