PFU titration of phage preparation in detergent and PBS
| Bacteriophage type | Bacteriophage titera
|
||
|---|---|---|---|
| PBS | PCHS | p | |
| Staphylococcus aureus | 7.7±1.9 | 8.5±1.3 | ns |
| Escherichia coli | 7.6±2.0 | 8.4±1.8 | ns |
| Pseudomonas aeruginosa | 7.8±1.8 | 8.6±2.0 | ns |
Notes:
a
Phages were titrated by soft agar method after 7 days in PBS or PCHS solution. Results are expressed as mean PFU ± SD ×106/mL in triplicate experiments.
Abbreviations: PBS, phosphate-buffered saline; PCHS, Probiotic Cleaning Hygiene System; PFU, plaque forming units; ns, not significant.
