A Loop-Mediated Isothermal Amplification Assay Utilizing Hydroxy Naphthol Blue (LAMP-HNB) for the Detection of Subspp. .

subspp. is a spirochaete bacterium that causes syphilis, one of the most common sexually transmitted diseases. Syphilis progresses through four distinct stages, each characterized by specific symptoms, namely primary, secondary, latent, and late (tertiary) syphilis.

Loop-Mediated Isothermal Amplification Assay Using Gold Nanoparticles for Detecting subspp. .

Background: Venereal syphilis in humans is caused by subspp. . A study has shown that 30,302 individuals in Thailand had syphilis in 2020, with a male-to-female ratio of 1:0.
