Effect of recombinant human macrophage colony-stimulating factor 1 on immunopathology of experimental brucellosis in mice.

abstract：:The mechanism(s) of interaction between Mycoplasma pulmonis and eucaryotic cells was studied by adherence to and hemagglutination of erythrocytes. Simple and complex carbohydrates and glycoproteins were unable to inhibit either adherence or hemagglutination, indicating that neither was a lectin activity. Both interact...
