Dear colleagues, after the great success of our first international MLVA ring trial we are now ready for the second on. We have already prepared a sample set with DNA from several Brucella strains which we could send to labs who want to participate. Everybody who could perform the MLVA 16 protocol published by Le Flèche et al., 2006 and Al Dahouk et al., 2007 is invited to join. Just e-mail me at falk.melzer@fli.bund.de
