Картофель поражается с заметным экономическим ущербом по меньшей мере 54 видами фитопатогенных грибов, 39 видами вирусов, 19 видами нематод, 3 видами фитоплазм и 11 видами бактерий. Бактериальные патогены вызывают болезни различной этиологии: от мокрой гнили до «зебры чипсов». Примерно 8-12 лет назад появились первые сообщения о проникновении и распространении новых возбудителей бактериозов во всех регионах России, в том числе о заболеваниях, вызываемых бактериями родов Dickeya dianthicola, D. solani и Clavibacter michiganensis subsp. michiganensis. В связи с усилением в России вредоносности бактериальных болезней картофеля, вызываемых различными группами бактерий, необходима точная идентификация патогенов, изучение путей их распространения, сохранения и разработка мер борьбы, ограничивающих распространение и обеспечивающих снижение ущерба от бактериальных болезней. Мы оценили распространение бактериальных патогенов картофеля как на основе собственных данных, так и по опубликованным сообщениям.Potato is affected at least by 54 species of phytopathogenic fungi, 39 viruses, 19 species of nematodes, 3 species of phytoplasmas, and 11 species of bacteria. Bacterial pathogens can cause diseases of different etiology: from "soft rot" to “zebra chips”. About 8-12 years ago, the increased severity of bacterial diseases in regions of Russia was reported, including diseases, caused by bacteria of genus Dickeya and Clavibacter michiganensis subsp. michiganensis. In connection with the increased harmfulness of bacterial diseases of sugar beet in Russia, caused by different groups of bacteria, we need an accurate identification of the pathogens, ways of their distribution, preservation, and search for control measures to limit the spread and reduce the damage from bacterial diseases of potato. We assessed and confirmed the distribution of potato bacterial pathogens based on own data as well as on reported incidence.

A study was undertaken for characterization and identification of the soft rot causing bacterial pathogens of onion. Bacterial pathogens were isolated from soft rotted stored onions of different varieties and locations of Bangladesh. Altogether 73 bacterial isolates were isolated from soft rotted onions. Among them, twelve soft rot-positive isolates were selected for characterization and identification on the basis of more virulence. Physiological and biochemical tests were performed following standard methods for characterization and identification of selected soft rot bacterial isolates. Seven isolates namely O-03, O-18, O-69, O-72, O-130, O-156 and O-180 were identified as Pectobacterium carotovorum subsp. carotovorum (E. carotovora subsp. carotovora), two isolates O-101 and O-118 were identified as E. chrysanthemi and three isolates O-05, O-14 and O-15 were the members of Burkholderia cepacia.Bangladesh J.

ABSTRACT Dickeya spp. are bacterial pathogens causing soft-rot and blackleg diseases on a wide range of ornamental plants and crops. In this paper, we announce the PacBio complete genome sequences of the plant pathogens Dickeya solani RNS 08.23.3.1.A (PRI3337) and Dickeya dianthicola RNS04.9.

Pectobacterium and Dickeya spp. are related broad-host-range entero-bacterial pathogens of angiosperms. A review of the literature shows that these genera each cause disease in species from at least 35% of angiosperm plant orders. The known host ranges of these pathogens partially overlap and, together, these two genera are pathogens of species from 50% of angiosperm plant orders. Notably, there are no reported hosts for either genus in the eudicots clade and no reported Dickeya hosts in the magnoliids or eurosids II clades, although Pectobacterium spp. are pathogens of at least one plant species in the magnoliids and at least one in each of the three eurosids II plant orders. In addition, Dickeya but not Pectobacterium spp. have been reported on a host in the rosids clade and, unlike Pectobacterium spp., have been reported on many Poales species. Natural disease among nonangiosperms has not been reported for either genus. Phylogenetic analyses of sequences concatenated from regions of seven housekeeping genes (acnA, gapA, icdA, mdh, mtlD, pgi, and proA) from representatives of these genera demonstrated that Dickeya spp. and the related tree pathogens, the genus Brenneria, are more diverse than Pectobacterium spp. and that the Pectobacterium strains can be divided into at least five distinct clades, three of which contain strains from multiple host plants.

Recent years have brought a reversal in the attitude of the medical profession toward the diagnosis of viral infections. Identification of bacterial pathogens was formerly thought to be faster than identification of viral pathogens. Viral identification was dismissed as being of academic interest or for confirming the presence of an epidemic, because the patient would recover or die before this could be accomplished. In the past 10 years, the goal of virologists has been to present the clinician with a viral identification in a matter of hours. This fast diagnosis has the potential for shortening the patient's hospital stay and preventing the administering of toxic and/or expensive antibiotics of no benefit to the patient.
