SPECIAL BACTERIOLOGY

The organism was discovered by Gessard in 1882. It 
is a short rod, Gram-negative, motile, has flagella, no 
spores, no capsules. It is an aerobic organism, faculta¬ 
tively anaerobic, grows well on simple media on which 
within twenty-four hours, a green pigment is formed. 
It produces both an exotoxin and endotoxin. As to the 
treatment a new method has been evolved during the 
present war which is by far better than anything so 
far used; this consists of applying a 1 per cent solution 
of acetic acid to infected areas; in three cases treated by 
this method at the Charity Hospital all three cases showed 
complete disappearance of green discharge within 
twenty-four to forty-eight hours.
