Researchers at the University of Delaware are examining how certain bacteria manage to bypass plant immune defenses.
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.
The plant has no symptoms of this invasion and once inside the plant, the pathogens cannot simply be washed out.
