Proteolytically activated antibacterial toxins inhibit the growth of diverse Gram-positive bacteria Many species of bacteria produce small-molecule antibiotics that enter and kill a wide range of competitor microbes. However, diffusible antibacterial proteins that share this broad-spectrum activity ...

A recent cool preprint by John Whitney's lab on a new family of antibacterial proteins secreted by Gram-positive bacteria that enter and kill a broad spectrum of bacteria. Cell entry is receptor-independent and relies on cleavage by a co-secreted protease and the PMF.

These people claim they are 'real' Christians. I am no specialist, but I thought the Bible was about welcoming the stranger, caring for the poor, and healing the sick... How do they reconcile their hatred for the majority of humans with their faith? That's a mystery.
