Mushroom glucan and bovine lactoferrin (Lf), known for their immunostimulatory potential, were used as adjuvant in conjunction with a formalin‐killed Aeromonas hydrophila vaccine in catla, Catla catla . In vitro antigen‐specific responsiveness of catla leucocytes and protective responses against experimental challenge with homologous antigen were monitored following immunization. Antigen‐specific proliferation, ‘macrophage activating factor’ (MAF) production and antibody production were significantly higher in fish injected with glucan adjuvanted vaccine. Lf adjuvanted preparations showed a weak proliferative response and MAF production, although the antibody production was significantly higher than the controls. A good degree of protection was achieved with the glucan adjuvanted vaccine. However, in spite of producing significant anti‐ A. hydrophila antibody, Lf adjuvanted vaccine did not confer any protection following challenge with A. hydrophila . The potential of adjuvanticity of mushroom glucan and bovine Lf in intraperitoneal vaccination is discussed.
