Detection of Listeria monocytogenes Scott A in skimmed milk by the bacteriophage amplification assay and standard method
| Standard method (log cfu/mL) | Phage amplification using laser light* (log cfu/mL) | ||
|---|---|---|---|
| Approx. 1 log cfu/mL | Approx. 2 log cfu/mL | Approx. 1 log cfu/mL | Approx. 2 log cfu/mL |
| 1.18 ±1.01a | 2.05±0.43b | 1.11 ±1.23a | 2.02±0.32b |
Means followed by the same letter are not statistically different (P>0.05)
Data is reported as log cfu/mL ± standard deviation
