| Abstract: | Since the observation of Landsteiner (1001) that .the blood ofhuman beings may be divided into several groups according to thepresence or absence of different iso-agglutinins and agglutinogensinthe blood serum and cells, the question as to whether these bloodgroups have each a different predisposition to immunologic and thera-peutic reaction has been raised and discussed by many workers.Concerning the relation of blood groups to the incidence and treat-ment of syphilis alone there has been published an abundant litera-ture. Alexander (1921), Schiitz and Wohlisch (1924), Straszynski(1925), Jacobsohn (1926), Bunker and Meyers (1927), Leveringhaus(1927), Gundel (1926, 1927 and 1928), Lickint and Troltzsch (1929),and Parr (1930) found the distribution of the disease among the bloodgroups to be the same as that of iiormal populations, but AmselandHalber (1925), Weichmann and Paal (1926), Kumazai and Namba(1927), Wilczkowski (1927), Warnowsky (1927) and Klopstock (1929)observed more people belonging to one group to be susceptible to thedisease than those of the other groups, although they all do not agreeupon the same group as being the least resistant to the infection. |
