摘要

A vaccine for protecting against a disease caused by a microorganism which does not synthesize nucleic acid precursors such as a Mycoplasma organism, which contains nuclease and/or a nuclease fragment or derivative which produces antibodies which recognize nuclease secreted or available on the surface of the microorganism against which protection is to be afforded. A vaccine may also be prepared from an antibody or fragment or derivative thereof which recognizes such nuclease of such microorganism.
