Abstract
Measured amts. of appropriate dilutions of the material being investigated are deposited on the surface of an agar medium. The liquid is absorbed readily into the agar and the bacteria are deposited on the surface. After a suitable period of incubation the colonies are counted and calculations made. The advantages of this method over the conventional pour plate procedure are pointed out. It may find practical application in the estimation of the number of bacteria in blood, feces, urine, milk, and other substances.Keywords
