Certain polypeptide fractions for use as an antimicrobial drug, drug compositions containing such polypeptide fractions, methods of reducing the infectivity possibilities of microbes by administering the polypeptide fractions, methods of preparing antisera using the polypeptide fraction, and a method of preparing the polypeptide fraction. The polypeptide fractions are characterized in that they are isolated from the body fluids of mussels, in particular Mytilus species such as blue mussel (Mytilus edulis), and in that they are capable of biospecifically binding sialic acid. The polypeptide fractions are active against a broad spectrum of viruses, bacteria and protozoa. |
