DEHYDRATED DEHYDRATED 



Bacto-Micro Assay Culture Agar and Bacto-Micro Inoculum Broth have been 

 developed for the cultivation of Lactobacilli in microbiological assays. These 

 media are also recommended for the cultivation of other Lactobacilli. A complete 

 discussion of Bacto-Micro Assay Culture Agar and Bacto-Micro Inoculum Broth 

 is given on pages 212 and 213. 



ADDITIONAL MEDIA 



The media listed below have been rather extensively employed in the past for 

 ^'Standard Methods" and supplementary procedures in the examination of water 

 and milk. Other media have been developed which are considered superior and 

 serve the purpose more adequately. For the present we will continue to carry 

 these media in stock for those laboratories where they have been in routine use, 

 or where it is desired to continue them for comparative purposes.

MEDIA FOR CULTIVATION 

 OF PATHOGENIC MICROORGANISMS 



INFUSION MEDIA 



Dehydrated infusion media, Difco, are prepared under controlled conditions 

 from large quantities of fresh tissue. Variations due to differences in meat are 

 thereby minimized, thus assuring greater uniformity of the final medium than 

 can be obtained when the medium is prepared in small lots from market meat. 

 Infusions of meat have long been considered an essential part of media for 

 the cultivation of many pathogenic organisms. Through years of practical use, 

 Difco infusion media have demonstrated their suitability for the cultivation of
