Fowl cholera (FC) caused by serotypes of Pasteurella multocida includes A:1, A:3, A:4 is a highly fatal septicemic disease. Preliminary trials of P. multocida A:1 bacteriophage lysate vaccine against FC was evaluated. Lytic phage and P. multocida ratio was standardized to obtain stable lysate batches. Consequently, three batches of lytic phage preparation were produced; estimation of protein and carbohydrate content amongst batches did not shown any significant variation indicating same batches can be produced by standardized procedure. Protective response trials in poultry with P. multocida A:1, A:3, A:4 against plain lysate and alum adsorbed lysate (1% alum) on vaccinated group showed both homologous and heterologous protection compared with inactivated whole cell group provided only homologous protection. Assessment of antibody response towards P. multocida A:1, A:3, A:4 antigen evaluated by Indirect Haemagglutination test (IHA) reveals presence of protective antibody titer.
