Bacterial infections are a global problem. The most common pathogens of infections among gram-negative bacteria are representatives of the Enterobacteriaceae family. Pectobacterium are gram-negative phytopathogenic bacteria belonging to the Enterobacteriaceae family.The purpose of the study is to develop methods for the identification of phytopathogenic bacteria. At the capacity of test components of developed identification algorithm, we used the data presented in the reference «Bergey’s Manual of Systematics of Archaea and Bacteria». research parameters and for selection of Model microorganisms bacteriological tests were reference strains of Pectobacterium carotovorum B-3455 obtained from the All-Russian collection of microorganisms and Pectobacterium carotovorum 333 from the collection of NRCEM Museum of FSBEI HE Ulyanovsk SAU named after P.А. Stolypin. From 50 samples of phytosanitary control and environmental objects, 5 strains were classified as Pectobacterium carotovorum spp. carotovorum.
