The article shows the analytical review of the literature about bacterial diseases, including bacterial dropsy, forest plants trees. Studied the symptoms of bacterial dropsy B.pendula in the study region. It is shown that the causative agent of this disease is a phytopathogenic bacteria Enterobacter nimipressuralis. The research of pathogens of bacterial dropsy birch in natural and artificial conditions. The comparative anatomical and morphological characteristics, physiological and biochemical isolated from birch strains of bacteria with the reference strains. The attention that is currently pathogen bacterial dropsy caused massive death of B.pendula in plantations of different age groups, and especially in ripen and mature stands. The morphology and structure of isolates on potato and meat-peptone agar. We studied the order and size of cells, their movement, the number and placement of flagella, Gram stain, etc., the ability of bacteria to ferment carbohydrates different sources in a synthetic medium using Omelyanskogo: glucose, sucrose, lactose, rhamnose, sorbitol, mannitol, salitsin etc. Pectolytic activity is established by culture of bacterial mass to potato slices. Of certain interest for science and practice of forestry up data on the distribution and severity of bacterial diseases based on a number of abiotic and biotic factors.The attention that is currently pathogen bacterial dropsy caused mass death B.pendula in plantations of different age groups, and especially in mature and mature plantations.
