Mycobacterium tuberculosis long-chain fatty acid resistome reveals universal stress protein TB15.3 as essential for infection - Communications Biology A genetic screen identifies long-chain fatty acid resistance mechanisms in Mycobacterium tuberculosis, and highlights a universal stress protein required for balanced long-chain fatty acid degradation...

How does Mycobacterium tuberculosis safely eat an antimicrobial (host-derived long-chain fatty acids)?

Here we show that it’s not through a dedicated mechanism but rather by fine tuning its metabolism.

Skin androgens affect virulence of Staphylococcus aureus Nature Microbiology, Published online: 27 February 2026; doi:10.1038/s41564-026-02281-ySex-specific differences in susceptibility to skin infections with Staphylococcus aureus are well described. Testosterone now emerges as a direct modulator of the accessory gene regulator quorum sensing system, increasing S. aureus virulence, which both explains sex-specific differences and informs treatment strategies.
