Fourth T6SS in Clinical Pseudomonas aeruginosa Uses Pore‑Forming Effector TseMt

The briefing

Researchers report that, in addition to the three commonly known T6SSs, some clinical Pseudomonas aeruginosa isolates carry a fourth system that deploys the pore‑forming effector TseMt. While details are limited in the brief, the findings expand understanding of the bacterium’s competitive and pathogenic mechanisms.
