چکیده
Synopsis--The TEST METHODS used by several workers, or recommended by official compendia, for the MICROBIAL CONTROL of pharmaceutical and cosmetic products are reviewed and discussed. Attention has been drawn to important factors which can influence the results of tests--such as product composition, sample preparation, time and temperature of incubation and culture media. Reference is also made to the need for the development of simple and quicker methods for ROUTINE APPLICATION. Comparative data between laboratories on the reproducibility of official test methods is also suggested.
