Phage infection fronts trigger early sporulation and collective defense in bacterial populations

The paper shows that sporulation in B. subtilis reduces phage plaque size by creating spore-rich rings that block phage access to susceptible cells.

Bacterium secretes chemical inhibitor that sensitizes competitor to bacteriophage infection

The paper identifies a bacterial secondary metabolite that sensitizes competitors to phage infection, providing a fitness advantage to the producer.
