Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, Volume 49, Issue 7, July 2026.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).
