This can be demonstrated by separating cells, allowing them to divide and then transferring individuals derived from them to agar containing a suitable concentration of antibiotic. Differences between single cells can be tested by four criteria: (1) division; (2) growth without division: (3) ability to resume division when transferred back to normal broth; (4) failure to lyse. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-12-2-269
