Flavobacterium psychrophilum strain Z2

Flavobacterium psychrophilum strain Z2 is a psychrophilic bacterium predominantly found in multiple habitats. It is characterized as a chemoheterotroph, relying on organic compounds for energy, and requires oxygen for its growth, making it an aerobic organism. The bacterium exhibits a rod shape and is non-motile, despite the presence of flagella. Flavobacterium psychrophilum strain Z2 thrives optimally at 15°C, within a temperature range that aligns with its psychrophilic nature. This strain has a single replicon and is associated with notable health effects in aquatic species, particularly in Oncorhynchus mykiss (rainbow trout) and other members of the Salmonidae family. It is known to cause bacterial cold water disease and rainbow trout fry syndrome, which can have significant implications for fish farming and wild fish populations. The nonsporulating nature of this bacterium means it does not form spores, which can influence its survival strategies in fluctuating environmental conditions. The accession number NZ_CP012586.1 is associated with this strain, providing a reference for further genetic and genomic studies. The ecological impact of Flavobacterium psychrophilum strain Z2 underscores its role in aquatic ecosystems, particularly as a pathogen affecting fish health. Understanding its biology can aid in managing disease in aquaculture and preserving the health of wild fish populations.
