Abstract
1. A study of the suspension of dried faeces used in the Chick-Martin test, and of the process of disinfection in this test has shown that:(a) The suspension of faeces is unstable, and rapidly forms a compact deposit.(b) Surviving bacteria in critical dilutions of the disinfectant are contained exclusively in this deposit.(c) Uncontrolled factors affect the degree of subdivision of the particles of faeces.(d) The degree of subdivision of these particles materially affects the activity of a disinfectant in their presence.2. It is suggested that these facts among others may account for inconstant results which the test is said to give.3. A suspension of yeast is proposed as a possible alternative form of organic matter in such a test.This publication has 1 reference indexed in Scilit:
