Sibling Lethal Factor
Discovered in 2000
Sibling colonies inoculated side by side can inhibit the growth of one another by secreting a protein label Sibling Lethal Factor, SLF.
Acts selectively on the same bacterial strain
In high amounts causes induced death of cells close to border
In sublethal amounts can induce morphotype and cell shape switching from cocci to motile rod shape.
Reversible
