Researchers capture bacterial infection on film
Researchers have developed a new technique that allows them to make a movie of bacteria infecting their living host.

The researchers can also tag individual bacterial proteins to follow their movement and determine their specific roles in the infection process. The scientists are hoping to use this system in the future with human pathogens such as Listeria and Trypanosomes. By observing how these bacteria interact with the immune system, researchers will gain a better understanding of how they cause an infection and could eventually lead to better antibacterial treatments.
Dr Will Wood, Research Fellow in the Department of Biology & Biochemistry at the University of Bath, explained: “Cells often behave very differently once they have been taken out of their natural environment and cultured in a petri dish. In the body, immune surveillance cells such as hemocytes (or macrophages in vertebrates) are exposed to a battery of signals from different sources. The cells integrate these signals and react to them accordingly. Once these cells are removed from this complex environment and cultured in a petri dish these signals are lost. Therefore it is really important to study whole organisms to fully understand how bacteria interact with their host.”
