Electric Charge of Bacteria Sensitized with Purified Agglutinins

[摘要] In pursuance of our studies concerning the electric charge of bacterial antigens and antibodies attention has been directed to the changes that occur in the electric charge when bacteria are treated with agglutinating sera. A number of investigators who have studied this problem have reported conflicting results. Bechhold (1904) found that unsensitized bacteria heated to 100°C. as well as those treated with agglutinin and then heated to 100°C. migrate to the anode; those treated with agglutinating serum and not heated were agglutinated between the electrodes nearer to the anode. Teague and Buxton (1907) concluded from experiments with various kinds of bacteria treated with agglutinating sera that without exception all migrated to the anode. In all cases the migration was well marked and in some cases as rapid as that of normal bacteria. Arkwright (1914) also found that bacteria whether agglutinated or not were always negatively charged.
