%X Objectives: Acellular pertussis vaccines has been largely accepted world-wide however, there are reports about limitedantibody response against these vaccines suggesting that multiple antigens should be included in acellular vaccinesto attain full protection. The aim of present study was to evaluate the role of Bordetella pertussis adenylate cyclase as aprotective antigen.Materials and methods: Highly mono-specific antibody against adenylate cyclase (AC) was raised in rabbits usingnitrocellulose bound adenylate cyclase and the specificity was assessed by immuoblotting. B.pertussis 18-323, wasincubated with the mono-specific serum and without serum as a control. Mice were challenged intra-nasally and pathophysiolgicalresponses were recorded.Results: The production of B.pertussis adenylate cyclase monospecific antibody that successfully recognized on immunoblotand gave protection against fatality (p< 0.01) and lung consolidation (p <0.01). Mouse weight gain showedsignificant difference (p< 0.05).Conclusion: These preliminary results highlight the role of the B.pertussis adenylate cyclase as a potential pertussisvaccine candidate. B.pertussis AC exhibited significant protection against pertussis in murine model. J Microbiol InfectDis 2012; 2(2): 36-43Key words: Pertussis; monospecific; antibody; passive-protection
