K. pneumoniae LAMP detection in pure cultures. (A) Representative fluorometric LAMP results, targeting the yhaI gene, performed on type strain (TS1) and clinical isolates (CS1–12) of K. pneumoniae from the United Kingdom, with H₂O as a negative control. (B) Representative colorimetric LAMP results, targeting the yhaI gene, performed on type strains (TS) and clinical isolates (CS) of K. pneumoniae from the United Kingdom (TS1–3) and from China (TS4 and CS13–18), as well as on type strains of E. coli, E. cloacae, Pseudomonas aeruginosa, and P. putida, with H₂O as a negative control.
