E. coli adapts to colonize plants
Date:10/30/2012

New research from the Institute of Food Research has given new clues as to how some E. coli strains, normally at home in mammalian gastrointestinal tracts, have adopted slightly different transmission strategies, with some being better adapted to live on plants than others.

In the light of recent outbreaks of food poisoning due to contamination of vegetables by dangerous strains of E. coli, this information will be useful to making sure our food remains safe. E. coli is most at home in the warm, moist, nutrient-rich environment found in the gastrointestinal tract of warm-blooded animals. But to disperse from one host to another these bacteria must get out into the world. There is evidence that some E. coli can survive for several weeks outside the host, and even grow in water or soil. But it is on plant matter that E. coli colonisation has become a concern, as although most types of E. coli are harmless, the presence of pathogenic strains on fruit and vegetables presents a food safety risk.

To find out more, the IFR team took the first comprehensive look at the differences between the populations of E. coli growing on crop plants and populations in the mammalian gut. Funded by the Biotechnology and Biological Sciences Research Council, they took over 100 isolates from leafy parts of vegetables growing in fields in England. Analysis of these showed that even within the same field the E. coli population is diverse and complex. They then compared these isolates with a standard reference collection of E. coli taken from mammals, including humans, from different continents. Profiling the two groups found a number of significant differences depending on the source of isolation. Compared to the habitat inside the gut, a leaf surface is a hostile environment for gut bacteria. The temperature fluctuates away from the constant 37 C inside our bodies, and there is a greater risk of drying out. '/>"/>
