abstract = {A colorimetric Loop-mediated isothermal Amplification (LAMP)
assay with hydroxy naphthol blue was designed for the detection of Lawsonia
(L.) intracellularis which is an important pathogenic bacteria that causes
animal diseases. A set of six primers was designed to target the aspartate ammonia-lyase
(aspA) gene. Serial 10 fold dilutions of cultured L. intracellularis
and spiked feces were used for LAMP optimization. The lower limit of the linear
range of the assay in L. intracellularis was 101 L. intracellularis
which is ten times more sensitive than conventional PCR. Based on testing in
210 porcine fecal samples using LAMP and conventional PCR, the agreement quotients
between LAMP and conventional PCR was 0.92. These results suggest that colorimetric
LAMP is a simple method for L. intracellularis detection in porcine
fecal samples.}
