Typhoid Fever 



previous one by Chantemesse and Widal, and has recently been 

 abundantly confirmed. 



The immunization of dogs and goats by the introduction of 

 increasing doses of virulent cultures has been achieved by Pfeiffer 

 and Kolle* and by Lofifler and Abel.f From these animals immune 

 serums were secured. 



WalgerJ reported 4 cases treated successfully with a serum ob- 

 tained from convalescent patients. Ten cubic centimeters were 

 given at a dose, and the injection was repeated in i case with relapse. 



Rumpf and Kraus and Buswell|| report a number of cases of 

 typhoid favorably influenced by hypodermic injections of small doses 

 of sterilized cultures of Bacillus pyocyaneus. 



Jez** believes that the antitoxic principle in typhoid fever is con- 

 tained in some of the internal organs instead of the blood, and claims

to have obtained remarkable results in 18 cases treated with extracts 

 of the bone-marrow, spleen, and thymus of rabbits previously in- 

 jected with the typhoid bacillus. 



Chantemesse, ff Pope,JJ and Steele have all used serums from 

 animals immunized against typhoid cultures for the treatment of 

 typhoid fever, with more or less success but an analysis of the results 

 shows them to be very inconclusive.
