. Difco manual of dehydrated culture media and reagents for microbiological and clinical laboratory procedures. Culture Media. 130 DIFCO MANUAL DIFFERENTIAL MEDIA Many media have been designed for the separation or differentiation of closely related organisms or groups of organisms. The differentiation by means of cul- tural characteristics is of decided value and importance especially where mor- phology and other biological characteristics are almost identical. The following dehydrated culture media represent a group of differential media, some of which are not selective and depend on cultural characteristics for differentiation, while others are selective and in addition show colonial differences between organisms. The isolation of members of the enteric group by means of differential media has been a routine procedure for many years. More recently differential media have been described for the isolation of other groups of organisms such as diphtheria, staphylococci and streptococci. Differential media for these isolation purposes are discussed in this section. Suggested Schema for the Examination of Stools or Other Material for Bacterial Incitants of Enteric Disease Specimen. Enrichment Bacto-Tetrathionate Broth Bocto-Selenite Broth Primary Ploting Medio Bocto-MocConkey Agar Bacto-Desoxycholote Agar Bacto-S S Agar Bocto-Desoxychoiote Citrate Agar Bocto-Bismuth Sulfite Agar Bacto-Brilliant Green Agar (only for Salmoneilo other than S. typhoso). Purification Plate Bacto-MacConkey Agar.
