DksA-Dependent Stringent Stress Response Drives Virulence and Gastrointestinal Persistence of Klebsiella pneumoniae

Md. Maidul Islam, Robert L. Beckman, Noah A. Nutter, Juan D. Valencia‐Bacca, Giovanna E. Hernandez, Renee M. Fleeman, Karen M. Haas, M. Ammar Zafar

This study identifies DksA as a key regulator of the stringent stress response in K. pneumoniae, linking it to antibiotic resistance, virulence, and gastrointestinal colonization.

Molecular response to the non-lytic peptide bac7 (1-35) triggers disruption of Klebsiella pneumoniae biofilm

Robert L. Beckman, Berta Martinez, Flor Z. Santiago, Gabriela N. Echeverria, Bruno V. Pinheiro, Marcelo D. T. Torres, Logan Suits, Shantal Garcia, Paeton L. Wantuch, César de la Fuente‐Núñez, Prahathees J. Eswara, David A. Rosen, Renee M. Fleeman

This paper investigates the anti-biofilm mechanism of bac7 (1-35) against Klebsiella pneumoniae, showing it disrupts bacterial membranes and ribosomal function, leading to biofilm collapse and reduced dissemination.
