Evaluation of the efficacy of a candidate turkey cellulitis/dermatitis oil emulsion vaccine on immune response and mortality under laboratory and commercial conditions

SUMMARY Ability of a Clostridium septicum (CS) bacterin-toxoid, in conjunction with adjuvants such as aluminum hydroxide, mannoslyated chitosan, or a water-in-oil emulsion Seppic Montanide 71 R VG adjuvant (OE) to induce immunity was evaluated in a 7-wk study (Experiment 1). Poults (20/group) were vaccinated on day of hatch, boosted at 5 wk of age and compared to unvaccinated controls. In Experiment 1, initial vaccination with OE resulted in significantly (P
