16,1 Fernandez: Focal Dental Infections 97 
lowed by me fully accord with the outline of treatment dis- 
cussed. Therefore, as the symptoms disappeared with the 
disappearance of the focus of infection, the symptomatic 
manifestations observed were related to the dental infections 
discovered. 
In cases where cultures were made, Streptococcus viridans 
associated with Staphylococcus was obtained in one case (3) ; 
and in the others, only Streptococcus viridans was found. Vac- 
cine of 100,000,000 per cubic centimeter was prepared from the 
microdrganisms obtained from each patient. 
Patients treated by the cure of affected teeth or by simple 
extraction showed gradual recovery, while those who received 
local treatment, associated with vaccine therapy, recovered more 
rapidly. 
In cases 9 and 10, the use of vaccine therapy, with polyvalent 
vaccine, gave positive results when associated with local treat- 
ment of the infection. 
I wish to express my appreciation to Prof. A. G. Sison for his 
courtesy in making the English translation of this work and for 
furnishing bibliographical references; to Prof. Jose S. Hilario 
for the preparation of vaccines; and to Dr. A. de Asis for his 
valuable codperation as a dentist.
