Aquatic circoviruses: emerging pathogens in global aquaculture - from discovery to disease management.

ABSTRACT: The expansion of global aquaculture has brought challenges from emerging pathogens, resulting in disease-related production losses across various regions. Among these pathogens, aquatic circoviruses-small, single-stranded DNA viruses initially detected in barbel (Barbus barbus)-have now been identified in multiple aquaculture species. These viruses have been associated with various clinical manifestations in economically important fish, crustacean, and mollusk species, including acute hemorrhage syndrome, which has shown mortality rates up to 95% in controlled laboratory infections of turbot. This review consolidates current knowledge on aquatic circoviruses, focusing on their genetic diversity, epidemiology, pathogenesis, and management strategies. The analysis encompasses observed
