Abstract

Serum antibody production ancl protection against A. hydrophila was examined in carp fish (Cyprinus carpio L.) . Heat killed (bacterin) A hydrophila was given by direct immersion and hyperosmotic infiltration at a dose of 108 cells/ml and there was different in antibody titers between immersion and hyperosmotic infiltration groups . Following the administration of bacterin, titer reached the peak in five weeks in carp fish from immersion groups and six weeks in carp fish from hyperosmotic infiltration groups . Upon challenge, the protective ability were significantly different between control and bacterin administration groups , but not statistically different between immer sion and hyperosmotic infiltration groups . A relatif level of 100% was obtained wiH1in four weeks, six weel<s , and eight wel~ ks and 96 ,67% was found two-weel<s post-bacterin administration . This study indicat ('IS that administration of bacterin A hydropflila by direct immersion or hyperosmotic infiltration resulted in increased protective immunity .
