Abstract
Broth suspensions of various organisms[long dash]Escherichia coli, Proteus vulgaris, Bacillus subtilis, hemolytic streptococcus (Lancefield''s group B) and Neisseria gonorrhoeae[long dash]were subjected to sonic vibration, using an electronically operated oscillator. The turbidities were measured in a photoelectric instrument, and the absorptions reported in terms of an absorption coeff. multiplied by a constant. Curves are presented showing the decreases in turbidity with length of time of treatment, and with increased voltage. The effectiveness of bacterioclasis decreases with increases in the quantity of culture under treatment.
