The author observed the lysis of Escherichia coli with phage by means of adding broth culture (0, 1ml) into phage of various concentration (10ml) and comparing the turbidity with the standard. As lysis was observable with Sh. Komagome A phage and Escherichia coli, the observation was chiefly done with this case. The results obtained are as follows.
1) With Escherichia coli, lysis was often unobservable. When the lysis was observable, it was still seen, even if the number of cells or the ratio of phage particles to bacteria was changed widely at the time of infection.
2) Shaking of the solution had a strong influence upon the turbidity curves.
3) The lysis curves changed according to the concentration of the added organisms.
4) There was no great difference between the bacteria that had been cultivated under the short-time aeration and the one that had been cultivated for 18 hours.
5) When the author operated Sh. komagome A phage on Sh. komagome A, Sh. saigon and E. coil, each of the three showed about the same sensitivity against this phage. However, there were quite large differences in their lysis curves. (See page 54-59.)
