Vibriosis vaccine trials were conducted on 4 Swedish brackish water rainbow trout Salmo gairdnen net-pen farms. Intraperitoneal (IP) vaccination of fall-and spring-transport yearlings at 3 to 16 "C provided s~gniflcant protechon against mortalities from Vibno anguillarum, serotype 1 (VA). Dipvaccination of fingerlings provided only slight protection of Lirmted duration. Non-vaccinated trout on one farm had a higher feed conversion rat10 (FCR) than corresponding vaccinated trout However, on 2 other farms, there were no significant differences in the FCRs of non-vaccinated and vaccinated trout Any benefits of the efficiency of food utilization conferred by vaccination therefore appeared to be farmspecific, but contributing factors were not identified

“…Since then, vibriosis has been a significant problem in Norwegian aquaculture (16,17,24,25,43,68). In general, vaccination is an effective prophylactic measure to control vibriosis (19,55), and it was introduced in Norway in 1977 (23). Vibriosis vaccines employed domestically contain antigen preparations of V. anguillarum serovars 01 and 02.…”

A total of 264 bacterial strains tentatively or definitely classified as Vibrio anguillarum were examined. The strains were isolated from diseased or healthy Norwegian fish after routine autopsy. With the exception of five isolates from wild saithe (Pollachius virens), the strains originated from nine different species of farmed fish. The bacteria were subjected to morphological, physiological, and biochemical studies, numerical taxonomical analyses, serotyping by slide agglutination and enzyme-linked immunosorbent assay, DNA-plasmid profiling, and in vitro antimicrobial drug susceptibility testing. The results of the microbiological studies were correlated to anamnestic information. The bacterial strains were identified as V. anguillarum serovar 01 (n = 132), serovar 02 (n = 89), serovar 04 (n = 2), serovar 08 (n = 1), and not typeable (n = 1) as well as Vibrio spkndidus biovar I (n = 36) and biovar II (n = 1), Vibrio tubiashii (n = 1), and Vibrio fischerii (n = 1). V. anguillarum serovar 01 or 02 was isolated in 176 out of 179 cases of clinical vibriosis in Atlantic salmon (Salmo salar). V. anguillarum serovar 01 was the only serovar isolated from salmonid fish species other than Atlantic salmon, while V. anguillarum serovar 02 was isolated from all marine fish suffering from vibriosis. A 48-Mda plasmid was isolated from all V. anguillarum serovar 01 isolates examined. Serovar 02 isolates did not harbor any plasmids. Resistance against commonly used antibiotic compounds was not demonstrated among V. anguillarum isolates. Neither V. splendidus biovar I nor other V. anguillarum-related species appeared to be of clinical importance among salmonid fish. However, such bacteria were isolated from diseased turbot (Scopthalmus maximus) and sea bass (Dicentrarchus labrax). The precise role of these bacteria as fish pathogens has to be elucidated. Cell and culture morphology, cell motility, hemolysis patterns, and especially alginate-degrading ability were found to be suitable characteristics for the differentiation of V. splendidus biovar I within the arginine decarboxylase-positive group of Vibrio species. Luminescence could not be demonstrated among V. splendidus isolates. Vibriosis due to Vibrio anguillarum is one of the most important bacterial infections in fish throughout the world (1, 19). The disease has great importance, particularly for marine fish farming (4, 15, 55). Infections have been reported also among farmed bivalve mollusks and crustaceans (11, 12). V. anguillarum and closely related bacterial species are commonly found in estuarine and coastal marine habitats and can readily be isolated from different environmental sources (31-34, 52, 65, 67). These bacteria constitute part of the normal microflora of healthy marine fish (34, 41, 45). On the basis of biochemical and serological differences, two distinct biotypes of V. anguillarum were described (6, 8, 19). Biotype 2 was later differentiated as a new species, Vibrio ordalii (54). A total of 10 different 0 serovars (01 to 010) and additional 0 subgroup...
