In the beginning, only a few leaves per branch are showing [...] xylem vessels in roots, stems and leaves and multiply. The plant may react by producing gum and tylose, a glue-like substance, in the vessels. The bacteria [...] found in leaves and fruits. The bacteria are transferred from plant to plant by all kinds of xylem-feeding insects. Well known, but certainly not the only

The first infection is often on the primary [...] orange-red masses of two-celled conidia are exuded. Secondary infection is by splash dispersal of these conidia. There is no known sexual stage.

• Bacterial wilt, brown rot

  eyes also turn grey-brown. This disease can be distinguished from Clavibacter by the bacterial slime produced from wounds, which is not seen in Clavibacter [...] found soil-inhabitant in tropical and subtropical regions and is transferred by the introduction of propagation materials (seed potatoes, cuttings of ornamentals [...] infected plants to neighbouring plants. The bacteria can also be transported by irrigation water. Disease incidence is highest when soil moisture is high
