Biocontrol of the Major Plant Pathogen

2019

Three new lytic bacteriophages were found to effectively control the pathogen Ralstonia solanacearum, a quarantine bacterium in many countries, and causative agent of bacterial wilt, one of the most important vascular plant diseases. Bacterial wilt management has been carried out with fluctuating effects, suggesting the need to find alternative treatments. In this work, three lytic phages were isolated from environmental water from geographically distant regions in Spain. They proved to specifically infect a collection of R. solanacearum strains, and some of the closely related pathogenic species Ralstonia pseudosolanacearum, without affecting non-target environmental bacteria, and were abl…

Comparing the Climatic and Landscape Risk Factors for Lyme Disease Cases in the Upper Midwest and Northeast United States

2020

Lyme disease, recognized as one of the most important vector-borne diseases worldwide, has been increasing in incidence and spatial extend in United States. In the Northeast and Upper Midwest, Lyme disease is transmitted by Ixodes scapularis. Currently, many studies have been conducted to identify factors influencing Lyme disease risk in the Northeast, however, relatively few studies focused on the Upper Midwest. In this study, we explored and compared the climatic and landscape factors that shape the spatial patterns of human Lyme cases in these two regions, using the generalized linear mixed models. Our results showed that climatic variables generally had opposite correlations with Lyme d…

Evolución social de virus

2023

Durante muchos años se ha asumido que los virus se transmiten como elementos individuales, en forma de partículas (viriones) que contienen un único genoma. En los últimos años, se ha incrementado sustancialmente la evidencia de que muchos virus son capaces de transmitirse en grupos de viriones, lo que les permite iniciar infecciones con más de un individuo, ya sea en un nuevo hospedador, o en una nueva célula, dentro de un organismo pluricelular. Concretamente, se han descrito multitud de estructuras, promovidas por genes virales, a las que se conoce como unidades de infección colectivas, que permiten el agrupamiento, transporte, y llegada conjunta de múltiples genomas o partículas virales.…

BIO–GEL – a new type of organic fertilizer

2017

A new technology for the production of the BIO -GEL organic fertilizer which is based on physical phenomena with no chemicals used has been suggested. The technology involves reproduction of “wild” microorganisms in peat, biohumus, sapropel, fertile soil. In the course of the production process natural bacteria are hardened at temperatures above 70°С and at low temperatures below - 20°С. BIO-GEL has combined the previously incompatible properties of inoculants, fungicides and humates.Field studies conducted for several years on sandy testing grounds at extremely high temperatures in the south of Ukraine have shown that the new fertilizer has pronounced properties of a natural herbicide, act…

The use of phage FCL-2 as an alternative to chemotherapy against columnaris disease in aquaculture

2015

Flavobacterium columnare, the causative agent of columnaris disease in fish, causes millions of dollars of losses in the US channel catfish industry alone, not to mention aquaculture industry worldwide. Novel methods are needed for the control and treatment of bacterial diseases in aquaculture to replace traditionally used chemotherapies. A potential solution could be the use of phages, i.e., bacterial viruses, host-specific and self-enriching particles that can be can easily distributed via water flow. We examined the efficacy of phages to combat columnaris disease. A previously isolated phage, FCL-2, infecting F. columnare, was characterized by sequencing. The 47 142 bp genome of the phag…

Detection of endophytic bacteria in leaves of Vitis vinifera by using fluorescence in situ hybridization

2008

Previous investigation on five cultivars of healthy Sicilian grapevine allowed the isolation of endophytic bacteria belonging to Bacillus genus from different organs (bud, leaf, stalk and shoot). The aim of this work was to use fluorescence in situ hybridization (FISH) experiments in healthy and damaged leaf tissues of Vitis vinifera to visualize and localize bacteria associated with plant materials. The leaves were cleared to minimize the autofluorescence of the plant fragments. The use of fluorescently labelled bacterial probe Eub338 in FISH experiments on discoloured grapevine leaf disks allowed the estimation of the spatial distribution of different bacterial colonies. At the same time,…
