Detection of specific antibody in adult human periodontitis sera to surface antigens of Bacteroides gingivalis.

abstract：:Administration of a standard bacterial vaccine (SBV) affords some protection against influenza infection in mice if given 4 to 5 h before inoculation of the virus. This effect was enhanced by repeated injections of SBV 7 and 14 days earlier, as measured by the length of survival, mortality rate, development of gross p...
