| Technique | TELLURITE SENSITIVITY ,(/,)/,( |
| Principle | Tellurite sensitivity can be demonstrated either on blood tellurite agar or tellurite polymyxin egg yolk agar (TPEY). |
| Cautions | |
| Method | Inoculate plates and incubate for 24 hours at 37 degrees C |
| Results | Tellurite resistant microbes reduce potassium tellurite to tellurium and show heavy growth of back colonies. Tellurite sensitive microbes either fail to grow or show a very light growth of pale colonies. |
| Positive control | Streptococcus faecalis, Staphylococcus aureus |
| Negative control | Streptococcus agalactiae |
