Immune Response of Trout to Aeromonas Salmonicida Part II. Evaluation of Feeding Techniques

Protection, immune responses and side effects in Atlantic salmon (Salmo salarL.) vaccinated against furunculosis by different procedures

“…However, they are in accord with several historical papers Table 3. published on vaccination against furunculosis. In spite of the successful pioneer oral vaccination experiment by Du# (1942), several authors subsequently failed to protect fish by the oral route (Snieszko & Friddle, 1949;Krantz et al, 1964;Spence et al, 1965;Klontz & Anderson, 1970;Hara et al, 1976;Udey & Fryer, 1978). Protection reported after immersion vaccination against furunculosis has been low to moderate Adams et al, 1988) or has been obtained in field experiments where the challenge was low (Palmer & Smith, 1980;Rodgers, 1990).…”

The infectivity by different routes of exposure and shedding rates of Aeromonas salmonicida subsp. salmonicida in Atlantic salmon, Salmo salar L., held in sea water

“…The role of transmission via an oral route is controversial. For example, Blake & Clarke (1931), Klontz & Wood (1972) and Sakai (1979) were able to infect various salmonid species via this route while other authors have been unable to do so (Krantz, Reddecliff & Heist 1964;McCarthy 1977). In view of the fact that undiluted furuncle material contains 10^*^cfu/ml.…”
