The physiological action and function of carotenoids have been investigated by experimental and epidemiological researchers. Some data showed that the intake of carotenoids enhanced the resistance to infectious diseases. In this paper, the influence of the petit vert, carotene-rich vegetable, on the resistance to infection was reported. BALB/c or ddY mice were administered petit vert juice p.o. for a week, and then inoculated i.v. with Listeria monocytogenes. The viable Listeria cell counts in the spleen and blood, and the life span of animals were assayed. In the petit vert treated group, the bacterial cell counts showed the maximum at 3rd day after inoculation, and the survival rates were 40 % and 70 % in the control group and the petit vert treated group respectively. These findings seemed to suggest that the resistance to infection was enhanced by the petit vert intake.
