Professor Jeff Errington, Director of the Centre for Bacterial Cell Biology describes their latest results on how L-form bacteria (lacking a cell wall) divide. These results might reflect the mechanisms early cells used to divide and proliferate.

The video shows bacterial cells on the left panel suddenly explode when penicillin is added because the pressure inside the cells increases, as penicillin inhibits synthesis of the bacterial cell wall. Healthy bacterial cells growing in the absence of penicillin are seen on the right.

Research in Prof Lakey's lab at ICaMB has identified a new molecule that can kill bacteria, which can potentially be developed as a new class of antibiotics. The tail of colicin N proved to have an unexpected effect: not only can it enter the bacterial cells, but it can killed them.

The video shows bacterial cells suddenly explode when penicillin is added because the pressure inside the cells increases, as penicillin inhibits synthesis of the bacterial cell wall. Notice how one cell, the persister cell (shown with an arrow) is surviving.These persister cells evade killing by antibiotics because they grow extremely slowly.
