Six Salmonella enteritidis bacterin formulations differing in adjuvant content and whole-cell inactivation procedures were evaluated in egg-laying chickens. Chickens given S. enteritidis bacterins containing modified Freund's incomplete adjuvant had greater humoral immune responses to S. enteritidis than did birds given other bacterin formulations (P < 0.05). Better protection against infection by S enteritidis phage types 8, 13a, and 23 was obtained in birds vaccinated with bacterin 5. Bacterin 5 contained S. enteritidis cells inactivated by 20% acetone and modified Freund's incomplete adjuvant.
