Eighty bacterial isolates with similar morphology were recovered. Bacteriophages (phages) are the most abundant biological entity in the biosphere with an estimated number of 10 31, as total prokaryotic cell numbers are understood to be around 10 30 in the biosphere and phage numbers are believed to be at least 10 times greater than this value (Whitman et al., 1998; Wommack and Colwell, 2000). Both genera cause pre- and postharvest losses of potatoes, resulting in huge economic losses linked with the soft rot diseases. This was identified as Pectobacterium carotovorum subsp.

Cultural characteristics. Pectobacterium carotovorum, a Gram-negative bacterium, can macerate parenchymatous plant tissues by producing a mass of plant cell-wall-degrading enzymes, including pectinases, proteases, cellulases, and hemicellulose (Haque et al., 2017, Meng et al., 2017).Then, it can cause soft rot, blackleg, and wilt in many vegetable crops and ornamental plant species pre- or post- harvest.

Stem rot is first noticed when plants wilt at the time of first harvest or after that. Its morphological features were examined by electron microscopy, which indicated that this phage belongs to the family Myoviridae . In more mature plants, blackleg appears as a black discoloration of previously healthy stems, accompanied by a rapid wilting and yellowing of the leaves ().Black discoloration of the stems always starts below ground and moves up the stem, often until the entire stem is black and wilted. This paper presents experimental results on the effect of carbon sources on biofilm formation and movement on the swarming type in a phytopathogenic bacterium . 52 compared to the sister clade, represented by Pectobacterium carotovorum. brasiliense is emerging as a causal agent of blackleg disease.
