Examples of false colonies are given in tne accompanying micrographs (Figures 36-1 and Lipids in chick embryo and in tissue can easily be confused with the fungoidal type of wall deficient bacteria; I I thus making microscopic studies with these preparations difficult. The artifacts are carried over to egg yolk-containing media such as

's and Loewenstein 's. used for growth of Mycobacteria. The need to employ medi ;1 Cree of egg components becomes obvious .
