An investigation into the antibiotic sensitivity of B. abortus biotypes to polymyxin B sulphate, amphotericin B, and bacitracin has shown that the dye-sensitive strains are also antibiotic-sensitive; and preliminary experiments suggest that these two properties are not genetically related.

The results suggest that biotype 2 can be subdivided on the basis of antibiotic sensitivity pattern, and that this could be of epidemiological significance.

Investigation into the antibiotic sensitivity pattern of the dye-sensitive variant B. abortus, biotype 4, leads us to believe that this strain should be reclassified as a separate biotype and provisionally called biotype 10.
