237 
time necessary for the detection of B. dysenteriz on this 
medium was much shorter as compared with the labor required 
to confirm the positive findings on the lactose litmus plate. 
CONCLUSION 
The methylene blue-eosin lactose medium designed by Holt- 
Harris and Teague, as modified by Meyer and Stickel and by 
us, is a considerable improvement in diagnostic technic. 
We wish to thank Dr. P. T. Lantin, of the Philippine General 
Hospital, who kindly supplied us with the material.
