Fig. 3From: Rapid and visual detection of Lawsonia intracellularis with an improved recombinase polymerase amplification assay combined with a lateral flow dipstickThe analytical sensitivity of the RPA-LFD assay was evaluated and compared with conventional PCR by using genomic DNA extracted from pure-cultured and number-determined L. intracellularis (a) as well as feces sample spiked with pure-cultured and number-determined L. intracellularis (b) as templates.
