The Ætiology of the Confusional Syndrome and the Use of T.A.B. Vaccine

Abstract

Since the discovery that Bacillus coli vaccine (1) or albumose (2) were as effective as typhoid vaccine (3) in the treatment of typhoid fever, the use of non-specific protein therapy has been popular for almost any disease for which there is no other satisfactory form of treatment. T.A.B. vaccine, a mixture of typhoid and paratyphoid A and B organisms, has been found more regular and reliable in its results than typhoid vaccine (4); but milk, antitoxic sera, peptone and a variety of other substances have been used, and even malaria is considered a form of this treatment, segmentation of the parasites producing the foreign protein (5). It has been observed that Gram-negative organisms, such as the gonococcus and typhoid bacillus, produce more marked reactions when given intravenously than the Gram-positive organisms, such as staphylococci, streptococci and pneumococci (5).
