Method for producing serum for preventing or treating mucosa-related infectious disease in calves, serum produced by the same method, and uses thereof

摘要

The present invention comprises the step of inducing the production of a protective antibody having mucosal immunity that can protect against infection of mucosal-related infectious pathogens from adult cattle by administering mucosal-related infectious pathogens to adult cattle through the mucosal route. A method of preparing a serum containing a protective antibody with mucosal immunity capable of defending against pathogen infection, and administering the serum prepared by the above method to a newborn or young calves to prevent young calves from infection by infectious pathogens, or Regarding the method of treatment, the method of the present invention allows young calves to be successfully prevented and treated from infection with mucosal-related infectious pathogens. The method of the present invention can be used as an effective means for preventing or treating infections of mucosal-related (digestive, respiratory and genital) infectious pathogens in young mammals that have not been solved by existing vaccines. .
