Abstract
The adjuvant effect of liposomes formulated with three phospholipids including phosphatidylcholine-liposomes (PC-Lip), phosphatidylserine-liposomes (PS-Lip), and stearylamine-liposomes (SA-Lip) was compared with virus alone using inactivated Newcastle disease virus (NDV) as a model antigen. The difference in adjuvanticity was evaluated using the haemagglutination-inhibition (HI) test, enzyme-linked immunosorbent assay, and a challenge study following intranasal inoculation of specific pathogen-free chickens.After two inoculations, a liposomal vaccine consisting of NDV in PC-Lip resulted in a significant increase in HI titre, up to 32-fold higher than a vaccine containing virus alone and 320-fold higher than a vaccine containing NDV in SA-Lip. PC-Lip also elicited a significant mucosal secretary immunoglobulin A response (P
