ABSTRACT. Bacterial strains of Aeromonas salmonicida included in the recognized subsp. achromogenes, subsp. masoucida, and subsp. smithia in addition to the large number of strains not included in any of the described subspecies are referred to as atypical A. salmonicida. The atypical strains form a very heterogeneous group w~t h respect to biochemical characteristics, growth conditions, and production of extracellular proteases. Consequently, the present taxonomy of the species A. salmonicida is rather ambiguous. Atypical A. salmonicida has been isolated from a wide range of cultivated and wild fish species, non-salmonids as well as salrnonids, inhabiting fresh water, brackish water and marine environments in northern and central Europe, South Africa. North America. Japan and Australia. In non-salmonid fish species, infections with atypical strains often manifest themselves as superficial skin ulcerations. The best known diseases associated with atypical A. salmonicida are carp Cypnnus carpio erythrodermatitis, goldfish Carassius auratus ulcer disease, and ulcer disease of flounder Platichthys flesus, but atypical strains are apparently involved in more disease outbreaks than previously suspected. Macroscopical and microscopical studies of ulcerated fish indicate internal organs are infrequently invaded by atypical A. salmonicida. This view is supported by the fact that atypical strains are ~rregularly isolated from visceral organs of ulcerated fish. High mortality caused by atypical A. salmonicida has been observed in populations of wild non-salmonids and farmed salmon~ds, although the association between the mortality in the wild fish stocks and atypical A. salmonicida has not always been properly assessed. In injection experiments the pathogenicity of the atypical strains examined showed large variation. An extracellular A-layer has been detected in different atypical strains, but virulence mechanisms different from those described for (typical) A. salmonicida subsp. salrnonicida, for example an extracellular metallo-protease and a different iron utilization mechanism, have been described. Limited information is available about the ecology, spread and surv~val of atypical strains in water. The commonly used therapeutic methods for the control of diseases in farmed fish caused by atypical A. salrnonicida are generally effective against the atypical strains. Resistance to different antibiotics and transferable plasmids encoding multiple drug resistance have been observed in atypical A. salmonicida. Studies aimed at producing a vaccine against atypical strains are in progress.

“…The second biogroup of Aeromonas is comprised of the motile, indole-positive species that grow optimally at 35 to 37°C and have been referred to as the Aeromonas hydrophila complex. Over the past 25 years, various investigators have proposed from one to four species within this complex, using designations such as A. hydrophila, Aeromonas punctata, Aeromonas caviae, Aeromonas dourgesi, and Aeromonas proteolytica to describe these species (6,9,22,29,30). In 1974, Schubert proposed that two species, A. hydrophila and A. punctata, each with specific subspecies, be recognized, based primarily upon acetylmethylcarbinol production and aerogenic utilization of glucose (31).…”

A group of 147 Aeromonas isolates from diverse clinical and environmental sources was subjected to the biotyping scheme of Popoff and Veron. Of the 147 isolates biotyped, 137 (93%) could be identified, with Aeromonas hydrophila predominating (48%) and equal percentages (25 to 27%) of the other two species (Aeromonas sobria and Aeromonas caviae). A number of additional biochemical properties were found to be significantly associated with one or more of these three species. These included lysine decarboxylase activity, hemolysis of sheep erythrocytes, lecithinase production, staphylolytic activity, arbutin hydrolysis, and acid production from utilization of various carbohydrates. By incorporating these phenotypic properties into an extended biotyping system, 98% of the isolates were identified. Selective distribution of individual species with respect to certain body sites was noted.

“…Since the classification of the aeromonads in Bergey's Manual has been termed inadequate, several proposals have been made for the reorganization of the genus, the most recent being that of Schubert (20)(21)(22). This report discusses the morphological and physiological characters of 12 strains of aeromonads isolated from clinical materials, in terms of the taxonomy and nomenclature recommended by Schubert for the revision of the genus Aeromonas.…”

Morphological and physiological characterization of 12 Aeromonas strains isolated from clinical specimens demonstrated several important diagnostic features. These included polar arrangement of the flagella; production of oxidase, deoxyribonuclease, amylase, gelatinase, and lipase; lack of ornithine decarboxylase; and sensitivity to polymyxin. Awareness of these features should result in more frequent differentiation of aeromonads from the physiologically similar members of the genus Plesiomonas and the lateor non-lactose-fermenting species of Enterobacteriaceae.
