About this work

Description

Salmonella Typhimurium is the causative agent of non-typhoid disease in humans and a wide range of animal hosts. This false-coloured transmission electron micrograph demonstrates the numerous flagella found on the bacteria. The diameter of the cell is 1µm. This image was produced as part of a research project investigating the effect of various gene mutations by allellic exchange. The mutations result in numerous phenotypes, including loss of flagella, an important factor for invasion of this serotype of Salmonella enterica.
