The reason for using the aorta is based on the fact that in humans Salmonella species can infect healthy aortic endothelial tissue causing possible aneurysm formation. We can culture S. typhimurium from aortas of mice after an intracardiac inoculation. Histologic examination of infected tissues suggests that initially the infection starts in the periaortic adipose tissue and then proceeds towards the muscle layer.
