Vibrio harveyi strain CAIM 1508 CAIM1508_a5_402

Vibrio harveyi strain CAIM 1508 (CAIM1508_a5_402) is a Gram-negative bacterium predominantly found in marine environments, particularly within aquaculture settings in the Changjiang estuary. This strain exhibits mesophilic temperature preferences and possesses flagella, facilitating its motility. The bacterium has a single replicon, indicating a streamlined genomic organization. The host range of V. harveyi CAIM 1508 is extensive, including various marine species such as Homo sapiens, Hippocampus abdominalis, and Penaeus vannamei, among others. This broad host range highlights its potential as a significant pathogen in both aquaculture and natural marine ecosystems. The strain is associated with several health issues, including septicaemia, vibriosis, gastroenteritis, and various diseases in fish and crustaceans. Notably, infections can lead to severe outcomes like mass mortality in seahorses, scale drop, muscle necrosis, and skin ulcers. The ecological implications of V. harveyi CAIM 1508 are profound, as it underscores the susceptibility of both cultured and wild marine species to bacterial infections, particularly in aquaculture environments where stress factors may be heightened. The prevalence of such pathogens can have cascading effects on marine biodiversity and the sustainability of aquaculture practices. Understanding the pathogenic mechanisms and host interactions of strains like CAIM 1508 is crucial for developing effective management strategies to mitigate the impact of vibriosis and related diseases in aquaculture.
