Vaccination of eels ( Anguilla japonicaand Anguilla anguilla) against Anguillicola crassuswith irradiated L 3
SUMMARY The original host of the swimbladder nematode Anguillicola crassus , the Japanese eel ( Anguilla japonica ) and the recently colonized European eel ( Anguilla anguilla ) were immunized with 40 irradiated (500 Gy) 3rd-stage larvae (L 3 ) of this parasite and challenged with an infection of 40...

The induced resistance (calculated using the relation of the number of adult worms in immunized eels and in non-immunized control eels) in A. japonica was 87·3%±30·4%. Following a single infection, the percentage of adult worms found in A. japonica was lower as compared to A. anguilla , and the few adult worms were much smaller, revealing a lower susceptibility of A. japonica to A. crassus in comparison to A. anguilla . Both eel species developed an antibody response against A. crassus , but the level of antibody responses was not positively correlated with the protection against infection, suggesting that the antibody response is not a key element in resistance of eels against A. crassus .
