| description | In Hungary, from the beginning of the 19th century, horse-chestnut trees have been planted widely and are popular ornamental trees in public parks, along streets, and in gardens. In the summer of 2015, longitudinal cracks on the trunk and branches and the intensive oozing of brown liquid were observed from a wound in a horse-chestnut tree in a park in Budapest. Some years later, in 2018 and 2019, the same symptoms were found in trees in other locations in Budapest. Several bacteria were reported that induce similar symptoms, including cracks and cankers on the bark of trunks and branches and sticky, white, red, brown, or black oozing. These pathogens belong to the genera <i>Brenneria</i> and <i>Lonsdalea</i>. Bark and exudate samples were taken with the aim of identifying the causal agent by conventional and molecular methods. Our results confirmed that the bacteria isolated from <i>Aesculus hippocastanum</i> trees belong to the genus <i>Brenneria</i> and phylogenetic analysis of the 16S rRNA gene region proved to have the closest phylogenetic relation with the <i>Brenneria nigrifluens</i> strains. |
