Supplements for MicroMedia Dehydrated Media
Each supplement is designed for specific dehydrated media bases used in microbiological diagnostics.
| Supplement | Recommended Dehydrated Medium | Medium Description | Purpose / Notes |
|---|---|---|---|
| Colistin & Nalidixic Acid | Columbia Agar / CNA Agar + 5% Sheep Blood | CNA agar is a selective blood agar inhibiting Gram-negative bacteria. | Selective for Gram-positive organisms (e.g., Staphylococcus, Streptococcus) |
| Potassium Tellurite 1% | Charcoal-based or Tellurite Agar | Tellurite agar is used for Corynebacterium species isolation. | Low-concentration tellurite supplement |
| Potassium Tellurite 3% | Charcoal-based or Tellurite Agar | Higher tellurite concentration for increased selectivity. | Suppresses background flora |
| Polymyxin & Ceftazidime | Charcoal or selective agar base | Charcoal media provide nutrient-rich conditions for Legionella. | Suppresses unwanted Gram-negative flora |
| Egg Yolk Emulsion | Egg Yolk Agar base | Egg Yolk Agar detects lecithinase and lipase enzyme activity. | Used for Clostridium, Bacillus, Staphylococcus species |
| Egg Yolk Tellurite | Egg Yolk Tellurite Agar | Combines lecithinase detection with tellurite reduction. | For Corynebacterium diphtheriae isolation |
| Cycloserine & Cefoxitin | CCFA (Clostridium difficile selective agar) | CCFA (Cycloserine Cefoxitin Fructose Agar) is selective for C. difficile. | Suppresses competing anaerobic bacteria |
| CN Supplement | BCYE (Buffered Charcoal Yeast Extract Agar) | BCYE agar supports Legionella growth with L-cysteine and ferric salts. | Enhances Legionella recovery |
| CFC Supplement | Chocolate Agar or BCYE base | CFC mix (Cefamandole, Fosfomycin, Cycloheximide) inhibits contaminants. | Selective for Legionella spp. |
| D-Cycloserine Supplement | CCFA or C. difficile selective agar | D-cycloserine inhibits most normal intestinal flora. | Alternative selection for Clostridium difficile |
| BCYE Growth Supplement | BCYE Agar Base | Provides essential amino acids, ferric iron, and alpha-ketoglutarate. | Supports Legionella growth |
| BCYE Growth Supplement (no L-Cysteine) | BCYE Agar Base (control) | Same as BCYE but lacks L-cysteine for control purposes. | Helps confirm Legionella dependence on L-cysteine |
| Ferric Ammonium Citrate (F.A.C.) | BCYE or CYE Agar Base | Provides an iron source for Legionella and other fastidious bacteria. | Essential for Legionella isolation |
| Polymyxin B Supplement | CYE or GVPC Agar Base | Antibiotic that suppresses Gram-negative background flora. | Used in Legionella selective protocols |
| GVPC Supplement | BCYE / CYE Agar Base | GVPC mix = Glycine + Vancomycin + Polymyxin B + Cycloheximide. | Highly selective Legionella GVPC medium |
