Description
Tri-Sugar Iron Agar (TSI) Test Tube – 5ml
The Tri-Sugar Iron Agar (TSI) Test Tube is an essential tool for microbiological analysis, specifically designed for the biochemical screening of Enterobacteriaceae family bacteria. Each box contains 20 individual 5ml test tubes, providing laboratories with a convenient and efficient way to conduct critical tests. These test tubes are particularly effective for evaluating carbohydrate fermentation and hydrogen sulfide production in bacterial cultures. These TSI test tubes enable accurate identification of bacteria, which is crucial for effective clinical diagnostics. These features make the TSI medium an indispensable part of any microbiological laboratory.
Key Features
- Packaging: Each 5ml TSI test tube is securely packaged in a plastic tube with an individual sterile seal. This ensures maximum protection against contamination and leakage during handling and storage. Furthermore, the design minimizes the risk of cross-contamination, enhancing the reliability of your results.
- Microbial Sensitivity Testing: The TSI test tubes allow for the inoculation of various quality control strains. For optimal results, incubate the inoculated tubes at 36±1°C in an aerobic environment for 18-24 hours.
Quality Control Strains
For effective testing, consider the following quality control strains that demonstrate specific characteristics when cultured in TSI:
| Quality control strain | Strain number | Inoculum (CFU) | Ratio or counting culture medium | Method | Quality control result | Other characteristics |
|---|---|---|---|---|---|---|
| Salmonella enteritidis | CMCCB(B)50335 | / | / | Qualitative | Good growth, K/A H2S+, gas production. | / |
| Escherichia coli | ATCCB25922 | / | / | Qualitative | Good growth, A/A H2S-, gas production. | / |
| Proteus vulgaris | ATCCB13315 | / | / | Qualitative | Good growth, A/A H2S+, gas production. | / |
| Shigella flexneri | CMCC(B)51572 | / | / | Qualitative | Good growth, K/A H2S-, no gas production. | / |
| Pseudomonas aeruginosa | ATCC27853 | / | / | Qualitative | Good growth, K/K H2S-, no gas production. | / |
