Hemagglutination titers of P. gingivalis mutants in bovine, chicken, sheep, and horse RBCs. There was no hemagglutination in horse RBCs by isogenic mutants. FLL401 showed high titers in bovine and sheep RBCs. FLL402 and FLL403 showed highest titers in sheep RBCs. Hemagglutination titer was determined as the reciprocal of the highest dilution showing complete hemagglutination.
