title: Immunogenicity of foot-and-mouth disease virus type O1 replicated in either monolayer or suspended BHK cell system.
abstract: The efficacy of vaccines formulated from the 10th passage of foot-and-mouth disease virus (FMDV) type O1 in monolayer baby hamster kidney (BHK) cells and the 8th passage in suspension BHK cells was compared in steers. The vaccines were inactivated with ethylenimine, contained an equal amount of antigen and were emulsified in oil-adjuvant. Six animals were vaccinated with each vaccine. During the challenge of immunity (91 days post-vaccination, DPV), one out of the six steers from the monolayer vaccine group became infected with the challenge virus while none of the six steers from the suspension vaccine group contracted the disease during the test period. The neutralizing antibody titers (means) of the serum samples taken at different DPV also did not suggest significant variation between these vaccines. In addition exposure to FMDV infected animals demonstrated that both vaccines elicited an immune state in the vaccinates.
