1 41 2 THE ENTEROIDEA GROUP OF TROPICAL FEVERS 



Symptomatology. — B. asiaticus No. i is associated with a long, 

 protracted, rather low fever of medium severity, which shows 

 usually a remittent or an intermittent character {vide Fig. 665). 

 B. asiaticus No. 2 produced a fever resembling certain types of 

 protracted enteric fever, but without any enlargement of the spleen, 

 without roseolcC, but associated with rather severe abdominal pains 

 of long duration, though as a rule there is no diarrhoea and the 

 stools never contain blood or mucus.

One case due to B. asiaticus No. i was associated with a severe 

 ancylostome infection, while one due to B. asiaticus No. 2 was 

 associated with a heavy ascaris infection. The fever did not stop 

 when the patients got rid of the parasites. 



Diagnosis. — The only possible method of diagnosis is the early 

 bacteriological examination of 5 to 10 c.c. of the blood taken asepti- 

 cally from the median basilic vein, and examined as already de- 

 scribed for enteric fever, while an attempt may also be made to

isolate the bacillus from the faeces. The specific bacillus will be 

 agglutinated by the patient's serum in high degrees of dilution. 



Treatment. — The cases must be treated on the lines already laid 

 down for enteric fever, but the most suitable special treatment is the 

 injection of autogenous vaccines prepared like the typhoid vaccines, 

 provided the acute symptoms are over and the fever is of very low 

 type. 



Khartoumensis Parenteric. 



This fever and its aetiological agent have been described by 

 Chalmers and MacDonald in the Sudan. The germ B. khartou-
