Structures of Class I and Class II Transcription Complexes Reveal the Molecular Basis of RamA‐Dependent Transcription Activation

Advanced Science, 2022
Transcription activator RamA is linked to multidrug resistance of Klebsiella pneumoniae through controlling genes that encode efflux pumps (acrA) and porin‐regulating antisense RNA (micF). In bacteria, σ70, together with activators, controls the majority

From Powder to Pathogen: A Systematic Review of Detection, Pathogenicity, and Mitigation of Cronobacter sakazakii in Infant Formula

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Cronobacter sakazakii is an emerging foodborne pathogen that has gained increasing global attention due to its association with severe infections in neonates, particularly meningitis, sepsis, and necrotizing enterocolitis. These infections are often associated with contaminated powdered infant formula (PIF), a nonsterile but commonly used alternative ...
