Abstract
This study investigates the potential use of chicken egg yolk-derived immunoglobulin Y (IgY) as an alternative to mammalian antibodies for passive immunization against Vibrio harveyi infections in Fenneropenaeus indicus. The research assesses the effectiveness of an immunogen derived from inactivated V. harveyi, with and without the immunoadjuvant Glycine max saponin. Purified IgY antibodies are prepared and characterized for their molecular weight, physicochemical parameters, and binding activity. The study aims to provide an alternative approach to combat Vibrio infections in aquatic species, offering a potential substitute for current antibiotic and synthetic drug delivery methods.
