난황면역제를 이용한 개 주요 소화기 및 호흡기질병 방제에 관한 연구 I. 개 보데텔라, 파보바이러스 및 개디스템퍼 항원의 닭에서의 면역반응

Control of canine respiratory and diarrheal disease using egg yolk antibodies I. Induction of antibody in hens immunized with combined antigens of Bordetella bronchiseptica, parvovirus and canine distempervirus

This study was carried out to produce IgY against B. bronchiseptica, parvovirus and distemper virus that are major pathogens in alimentary and/or respiratory diseases of dogs. In the comparison of adjuvants, ISA70 was the best in the rapid induction and maintence of antibody titers. Agglutination antibody titers against B. bronchiseptica were 1:1,280 ~ 1:10,240 in sera and 1:160 ~ 1:1,280 in egg yolk. Hemagglutination inhibition(HI) titers against parvovirus in sera and egg yolk were 1:80 ~ 1:320 and 1:64 ~ 1:256, respectively. Virus neutralization titers against canine distemper was 1:8 ~ 1:64 in sera and egg yolk. These results suggested that egg yolk antibody titers could be variable according to a sort of adjuvant and antigens of the pathogens.
