Plants have resources, and bacteria want them. Plants have gates on their leaves to keep the thieves out. But a nasty bug called Salmonella has figured out how to trick plants into opening up their safety gates so it can sneak in and live happily inside.

When people eat those contaminated leaves, they can get sick, sometimes severely. Because the bacteria are actually inside the leaves, they cannot be removed by washing.

Salmonella infections cause about a million deaths a year worldwide, and there is an urgent need for better vaccines for both typhoid fever and non-typhoidal Salmonella disease. New work from researchers at the 51�ԹϺ�� Davis School of Veterinary Medicine shows how memory T cells, crucial for a vaccine that induces a powerful immune response, can be recruited into the liver in a mouse model of Salmonella.
