Importance of manganese uptake in uropathogenic Escherichia coli CFT073 during urinary tract infection.

Manganese uptake via Sit and MntH is essential for UPEC CFT073 to resist oxidative stress and establish infection during urinary tract infections.

• Why it matters: UTIs are highly prevalent and increasingly resistant to antibiotics, making it crucial to understand bacterial survival mechanisms and identify new therapeutic targets.
• What they did: Researchers used a murine UTI model and gene deletion techniques to study the roles of manganese and iron transport systems, focusing on sitABCD and mntH in UPEC CFT073.
• The result: Disruption of manganese transport significantly impaired bacterial fitness and infection in the urinary tract, suggesting manganese acquisition as a promising target for novel UTI treatments.
