BACTERIAL INOCULATION 291 



Pneumonice, Diphtheroid bacilli, B, tuberculosis, Fried- 

 lander's bacillus and Streptothrix actinomycosis. Pul- 

 monary diseases offer an exceptional field for bac- 

 terin therapy, owing to the unusual vascularity of the 

 tissues, permitting the opsonins to become effective. 

 Consequently, brilliant results are achieved routinely 

 both curatively and prophylactically (Fig. 5Q) , This, 

 of course, does not apply to tuberculosis and actino- 

 mycosis nearly to the degree that it does to other 

 infections. 



Pneumonia, — Essentially the same bacteria are to 

 be found as in bronchitis. Keen discrimination must 

 be exercised not to employ bacterins if there exists a 

 doubt of bactersemia, otherwise the employment of 

 autogenous bacterins in adequate dosage will lessen 

 mortality and shorten convalescence. The opsonic 

 index here as in bronchitis should be utilized to secure 

 the best results. In unresolved pneumonia and 

 bronchopneumonia of childhood a special field of use- 

 fulness is offered autogenous bacterins. Prophylactic 

 immunization applies in pneumonia the same as in 

 bronchitis and in the event of epidemics should be 

 routinely practiced. The protective dose is 1,000,- 

 000,000 pneumococci. 



Purulent Bronchiectasis and Pulmonary Ab- 

 scesses, — The bacteriology differs in no respect from 

 that of bronchitis and pneumonia. The expectoration
