Abstract—Fire blight disease caused by the bacterium Erwinia amylovora is among the most serious threat to rosaceous, was introduced for the first time in Morocco in 2006. Since, the disease propagated then in wide causing immense damages. The objective of this work is the characterization of E.amylovora the population collected between 2006 and 2011. Characterization performed on a collection of 402 strains of E.amylovora from different regions of pome fruit. The obtained results demonstrated a big diversity of the Moroccan collection as well on the phenotypical and biochemical plan, the capacity of certain isolates to degrade the galactose, in particular of the hydrolyseesculin and appearance of colonies on MM2Cu and CCT media. Such as on the molecular plan in particular the ability of multiplex PCR analysis with PEANT1/2, pEA71F/R, EaIsc F/R to identify the E.amylovora strains and the detection of absence of plasmid pEA29 in a few strains.
