| Abstract |
|
Immunoprophylatic effect of IgY against B. bronchispetica was proven with 100% preventive rate in mice administrated with IgY with antibody titer 1:640~1:2,560. Intramuscular administration was more efficient than oral administration. This phenomenon was also observed in the therapeutic effects of IgY after challenge with B. bronchseptica in mice. In the field trials with the egg yolk antibodies from hens immunized with combined antigens with B. bronchiseptica and parvovirus, curing rates in dogs with severe clnical signs such as bloody diarrhea were 81.6% and 86.7% by intramuscular or subcutaneous administration of IgY, respectively. Safety of the antibodies in dogs was proven without any side effects such as vomiting, edema, fever, etc. by adminstration of double doses for 7 days. These results indicated that the egg yolk antibodies could be used as effective prevention and treatment of alimentary and respiratory diseases in dogs. |
