Abstract:

Flavobacterium psychrophilum is an important pathogen of freshwater fish, implicated in skin and internal organs disease, often causing high mortality. The phenotypic and biochemical analysis revealed 42 isolates of Flavobacterium genre (including 7 strains from Rainbow trout with Flavobactrium psychrophilum, from two different countries). There was a great phenotypic heterogeneity (9 different biotypes). These variations are found in colony morphology, pattern of biochemical reactions and variability in analysis of enzymes production. In Morocco, many outbreaks of skin diseases have been observed in fish that resemble Flavobacterium psychrophilum, to date, without a laboratory confirmation. The main fish species involved in the Rainbow trout and Coho Salmon, with high mortality rates in fry production units (hatcheries) were observed. The aim of this study was to report the isolation and characterization of Moroccan strains of F. psychrophilum, from juveniles compared with other countries strains.
