“…However, it has been suggested that the mortality in carp populations was caused by invasion of opportunistic pathogens, facilitated by the immunosuppressive substances released by atypical A. salmonicida (Evenberg et al 1986, Pourreau et al 1986, Sovenyi et al 1988). …”

In some studies the injected amount of bacteria was not reported (Bucke 1980, Michel 1981, Sovenyi & Ruttkay 1986, Sovenyi et al 1988. The age and the genetic strain of the fish (e.g.…”

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.

“…These results are also similar to those of experimental infections in other types of cultured fish. Gjedrem et al (1991) has shown genetic variation in families of Atlantic salmon (Salmo salar) for furunculosis resistance and Sövényi et al (1988) has shown similar di#erences in susceptibility to (Aeromonas salmonicida) infection in common carp (Cyrpinus carpio).…”

“…Selection may be based directly on survival records, or indirectly using immunological markers (Anderson 1990). Genetic variation in survival against a variety of diseases has been previously documented in salmonids (Gjedrem et al 1991), tilapia, Oreochromis niloticus (Sarder et al 2001), and carp (Sövényi et al 1988;Wiegertjes et al 1993).…”

Males of two strains of carp, wild Duna (D), and inbred Szarvas 22 (22), were selected for high and low stress response. Two purebreds of D and 22, from randomly chosen parents and four crosses, 22 x 22-L (low stress response), 22 x 22-H (high stress response), 22 x D-L (low stress response) and 22 x D-H (high stress response) from selected stress response parents were produced and vaccinated with a commercial Aeromonas salmonicida/Aeromonas hydrophila vaccine and their circulating antibody response evaluated 1, 3, 5, and 7 weeks post-vaccination by ELISA. Significantly higher titres of circulatory antibodies against A. hydrophila were found in the families 22 and cross 22 x 22-L compared to other groups. The development of circulatory antibodies against A. hydrophila in all crosses having at least one D parent was low and remained low throughout the experiment. The level of circulatory antibodies against atypical A. salmonicida in the inbred strain increased following a booster vaccination with the highest values measured in inbred strain 22 and cross 22 x 22 L. The different varieties of carp had different levels of survival against experimental challenge with A. hydrophila. The greatest survival was obtained in strain 22 and cross 22 x 22-L, while ~90% of D wild carp and cross 22 x D (independent of their stress response) died. Survival results correlated well with the antibody response of the different groups: 22 and 22 x 22-L had the highest antibody titres against A. hydrophila and the greatest level of survival.
