Figure 4. The LAMP amplification graph obtained when testing human fecal specimens spiked with the low level of L. ivanovii strain after various enrichment periods (2, 4, 6, 8, 10, 12, 14 and 24 h) in Half Fraser’s broth.
The human fecal specimen was spiked with 8 CFU/0.5 g of L. ivanovii strain ATCC BAA-678.
