摘要：

JT71 is a newly identified compound that inhibits the MrkH-dependent activation of type 3 fimbriae synthesis and biofilm formation in Klebsiella pneumoniae. This inhibition is crucial as biofilms contribute significantly to the pathogenicity of this organism, particularly in nosocomial infections. The compound was shown to reduce biofilm formation by 50% without affecting cell viability, indicating its potential as a therapeutic agent against multidrug-resistant strains. JT71's specificity and non-toxic profile make it a promising candidate for further development in preventing biofilm-related infections.
