Haemagglutination caused by the cells of Aeromonas salmonicida was investigated using 114 strains isolated from natural outbreaks of furunculosis in salmonids from 1967 through 1982. Haemagglutination by autoagglutinating strains was specific for erythrocytes of salmonids, including rainbow trout Salmo gairdneri, sockeye salmon Oncorhynchus nerka, masu salmon O. masou, chum salmon O. keta and coho salmon O. kisutch, but not for the erythrocytes of cyprinids and other fish species, including goldfish Carassius auratus, crucian carps Carassius spp. and tilapia Sarotherodon niloticus, or for mammals (sheep and humans). In a slide haemagglutination assay, these strains were categorized into the following two types: a haemagglutinating type and a non-haemagglutinating type for rainbow trout erythrocytes. Based on the occurrence of the two types as determined in 1978 and 1982, the results showed that the haemagglutination proceeded from a haemagglutinating to a non-haemagglutinating type in each strain. The phenotypic variation in haemagglutination corresponded with the variation in autoagglutination, which progressed from an agglutinating to a non-agglutinating type. This suggests that the haemagglutinative property is closely related to the capacity of autoagglutinating strains to adhere to salmonid erythrocytes.
