Abstract. The indirect immunoperoxidase technique (IPT) was used to examine specific superficial colonies of organisms observed on the gills of salmonids. The evidence obtained suggested that the superficial colonies were not a form of Aeromonas salmonicida , the causative agent of furunculosis. Application of the IPT to bacterial smears and previously stained histological sections from a case of furunculosis, confirmed the sensitivity of the technique and suggested the presence of common antigens between A. salmonicida and members of the Vibrionaceae, Pseudomonaceae and Enterobacteriaceae.
