Pseudomonas cichorii is a Gram - very polyphagous bacterium , which is widely distributed in the world and on almost all continents (Japan, USA, Italy, Portugal, Spain). It is found as well on lettuce as on chicory ... It is rife from time to time in association with one or more of the other bacteria described on salad.

In France , as in many countries, it is mostly found in autumn and winter on rather aged salads.
