Congratulations to Jordi Zamarreño Beas, Filipe Folgosa, Val Karavaeva, Filipa L. Sousa & Lígia M. Saraiva on their new publication in Nature Scientific Reports:

A novel type of hemoglobin confers host-derived nitric oxide resistance to the opportunistic pathogen Acinetobacter baumannii

This study reports the discovery of a new type of globin in the multidrug-resistant Acinetobacter baumannii. Bacterial (hemo)globins play a key role in nitric oxide detoxification, a crucial process that helps pathogens evade the immune system. Understanding bacterial stress adaptation mechanisms is essential for developing new strategies to combat multidrug-resistant bacteria.
