Development of a loop‐mediated isothermal amplification‐lateral flow dipstick (LAMP‐LFD) assay and on‐site rapid detection evaluation for Rodentibacter heylii and Rodentibacter pneumotropicus

Animal Models and Experimental Medicine, EarlyView.
This study established a closed‐tube LAMP‐LFD assay for detecting Rodentibacter heylii and Rodentibacter pneumotropicus. The method exhibited high sensitivity (detection limits of 10−5 ng/μL for R. heylii and 10−4 ng/μL for R. pneumotropicus), high specificity, reliable performance with clinical samples, and effective validation in experimental ...
