Abstract
A cluster of time-linked cases and the identification of a clonal strain suggest the occurrence of an outbreak of listeriosis in Belgium in 2011, presumably due to the consumption of hard cheese made with pasteurised milk and produced by a Belgium manufacturer. The outbreak clone was identified as Listeria monocytogenes serovar 1/2a, sensitive to arsenic and cadmium and of multilocus sequence typing MLST-type 37. Food investigation of this outbreak was facilitated by the European Epidemic Intelligence Information System and data exchanged between French and Belgium listeriosis surveillance systems.

Abstract
The influence of four agar-type polysaccharides, used as solidifying agents for culture media and differing in their sulfate content (0.14 to 10.95 % w/w), was tested on the budding and the elongation of five clones of Thuja plicata. Budding is reduced on the most sulfated polysaccharide and the differences observed between clones in elongation are as important as those observed between agar types.
