Furunculosis is a bacterial disease of salmonids. It is usually characterized by boils or furuncles on the skin of affected fish although this is not always the case. If there are multiple heads, the lesion is called a ‘carbuncle’. Large boils form abscesses, defined as an accumulation of pus within a cavity. Cellulitis may also occur, i.e. infection of the surrounding tissues, and this may cause fever and illness. This disease infects salmon species worldwide, with both typical and atypical strains causing disease. Symptoms of Facial Furunculosis in TCM include:
