As the world battles against the coronavirus pandemic (COVID-19), which emerged after the virus moved from animal to human, researchers at the University of Delaware are learning new ways to other pathogens jump from plants to humans

Opportunistic bacteria,  Salmonella ,  Listeria  and  E. coli , for example – often attach themselves to raw vegetables, poultry, beef and other foods to enter a human host, causing millions of illnesses each year food.

But researchers from the University of Delaware,  Harsh Bais  and  Kali Kniel  and their collaborators have now discovered that wild strains of  Salmonella  can bypass a plant’s immune system, penetrating lettuce leaves by opening tiny pores. of the plant called stomata.
