PRINCIPLES OF BACTERIOLOGY 
known as Crede’s treatment has practically eliminated 
this babies’ scourge. 
The patients should be isolated, and everything 
touched by them should be most scrupulously disinfected; 
they should be warned of the danger of infecting their 
eyes, and the nurse should be extremely careful in dis¬ 
infecting her hands and had best put a drop of a 10 per 
cent solution of agyrol in her eyes once a day. 
VI. Mechanism of Infection and Immunity 
Gonococci produces endotoxins; the immune bodies 
concerned in recovery are bacteriolysins, opsonins (phag¬ 
ocytosis is very important). 
VII. Bacteriologic Diagnosis 
Bacteriologic diagnosis is made on finding a Gram¬ 
negative diplococcus, biscuit shaped, and within the pus 
cells. 
VIII. Immune Treatment 
The gonococcus vaccine is used only in chronic cases, 
and in these gives very good results. 
IX. Summary of Important Characteristics 
Gram-negative, biscuit shaped, diplococci, found within 
pus cells, no spores, no flagella, no capsules, grow only on 
ascitic fluid agar, cornstarch agar, or other “rich” media, 
cause gonorrhea, sometimes rheumatism and heart disease, 
produce endotoxin; the vaccine treatment well worth 
trying in chronic cases.
