From: Short-term genome evolution of Listeria monocytogenes in a non-controlled environment
Schematic of the putative evolutionary history of the L. monocytogenes strain in the food facility between 1988 and 2000. Numbers on the arrows represent new mutations. Ancestor A is the ancestor of F6854 and F6900 (the food and human isolate, respectively, from the sporadic case in 1988) and Ancestor B is the ancestor of J0161 and J2818 (the food and human isolate, respectively, from the outbreak in 2000).
