Attenuation of Quorum Sensing Regulated Virulence of Pectobacterium carotovorum subsp. carotovorum through an AHL Lactonase Produced by Lysinibacillus sp. Gs50
Quorum sensing (QS) is a mechanism in which Gram negative bacterial pathogens sense their population density through acyl homoserine lactones (AHLs) and regulate the expression of virulence factors. Enzymatic degradation of AHLs by lactonases, known as quorum quenching (QQ), is thus a potential strategy for attenuating QS regulated bacterial infections. We characterised the QQ activity of soil ...
متن کاملTaxonomic relatedness between Pectobacterium carotovorum subsp. carotovorum, Pectobacterium carotovorum subsp. odoriferum and Pectobacterium carotovorum subsp. brasiliense subsp. nov.
AIMS Pectobacterium carotovorum is a heterogeneous species consisting of two named subspecies, P. carotovorum subsp. carotovorum and P. carotovorum subsp. odoriferum. A third subspecies, P. carotovorum subsp. brasiliense, was previously proposed. The study aimed to confirm the subspecies status and validate the proposed name of P. carotovorum subsp. brasiliense using a novel and standard microb...
متن کاملComplete genome sequence of Pectobacterium carotovorum subsp. carotovorum bacteriophage My1.
Pectobacterium carotovorum subsp. carotovorum, a member of the Enterobacteriaceae family, is an important plant-pathogenic bacterium causing significant economic losses worldwide. P. carotovorum subsp. carotovorum bacteriophage My1 was isolated from a soil sample. Its genome was completely sequenced and analyzed for the development of an effective biological control agent. Sequence and morpholo...
متن کاملجداسازی باکتری‌های دارای خاصیت quorum quenching با قابلیت بیوکنترل Pectobacterium carotovorum subsp. carotovorum
تعداد 177 جدایه باکتری کونچر به دو روش استفاده از محیط کشت حداقلی حاوی سیگنال آسیل همو سرین لاکتون از نوع 3-oxo-C6-HSL و محیط کشت‌های عمومی از گیاهان تیره‌ی سولاناسه جداسازی شدند. از بین آنها 11 جدایه متعلق به جنس‌های Pseudomonas، Enterobacter،Acinetobacterو Bacillus فعالیت کونچری بالایی داشتند. بهویژه جنس Pseudomonas که دارای بالاترین میزان فعالیت بود. بررسی سازوکار کونچری در این باکتری‌ها نش...
متن کاملSoft rot of calla is caused mainly by the bacterium Pectobacterium carotovorum subsp. carotovorum (Pcc)
We studied bacterial isolates 15M and 16M from calla lily tubers showing soft rot in commercial plantations in Poland. Colony morphology differed from that of known agents of bacterial soft rot of this plant. The use of Microgen Bacillus ID system allowed to identify both isolates as Paenibacillus polymyxa. This was confirmed by sequence analysis of 16S rRNA gene fragments. The isolates showed ...
