| 摘要 |
A bacterial antigenic lysate prepared by subjecting to lysis selected bacterial strains, particularly Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Diplococcus pneumoniae, Klebsiella pneumoniae, Klebsiella ozaenae, Haemophilus influenzae type B, Neisseria catarrhalis, is described. The obtained lysates are useful as vaccines to be administered by the oral route for the treatment of infective diseases of the respiratory tract, particularly to prevent relapses and transformations into chronic conditions. |
