Transient colonization by Priestia megaterium B1L5 alters the structure of the rhizosphere microbiome towards potential plant beneficial bacterial groups in apple plantlets.

Background: Plant growth-promoting bacteria (PGPB) can beneficially modulate rhizosphere microbial communities, potentially improving plant health and reducing disease incidence. Limited research exists on the influence of PGPB inoculation on the rhizosphere microbial communities of apple plants, particularly in soils affected by apple replant disease (ARD). Here, we evaluated the capacity of GFP-labelled B1 (designated as B1L5) to colonize the roots of apple plantlets grown in two soils: ARD-affected soil and ARD-unaffected grass soil.

Inoculation of apple plantlets with Rhodococcus pseudokoreensis R79 enhances diversity and modulates the structure of bacterial rhizosphere communities in soil affected by apple replant disease.

Background: Apple replant disease (ARD) represents a dysbiotic rhizosphere condition potentially driven by root exudates including phytoalexins at the root-soil interface. A promising mitigation strategy could be the application of bioinoculants that reduce these compounds and foster a diverse microbiome. This study investigated the effects of Rhodococcus pseudokoreensis R79, a strain with benzoate-degrading capabilities and genetic potential to degrade biphenyls, on the rhizosphere microbiome of apple plantlets grown in ARD-affected soil in a greenhouse experiment.

Comparative genomic analysis of strain B1 reveals conserved potential for adaptation to endophytism and plant growth promotion.

In our study, we aimed to explore the genomic and phenotypic traits of strain B1, which was isolated from root material of healthy apple plants, to adapt to the endophytic lifestyle and promote plant growth. We identified putative genes encoding proteins involved in chemotaxis, flagella biosynthesis, biofilm formation, secretory systems, detoxification, transporters, and transcription regulation. Furthermore, B1 exhibited both swarming and swimming motilities, along with biofilm formation.

Draft Genome Sequence of the Bacterial Endophyte B1, Isolated from Roots of Apple ().

Over the past years, a number of important traits supporting plant growth have been shown for different strains of Priestia megaterium (formerly known as Bacillus megaterium). Here, we report the draft genome sequence of the endophytic bacterial strain B1, which was isolated from surface-sterilized roots of apple plants.

Bioactivities of endophytic actinobacteria inhabiting Artemisia herba-alba emphasizing differences from free-living strains.

The endophytic actinobacteria associated with Artemisia herba-alba (synonym: Seriphidium herba-alba) are highly diverse. This study aimed to illustrate the extent of their differences from the free-living actinobacteria in the surrounding environment. A selection of eighteen actinobacteria inhabiting A.

pneumonia with bacteremia without meningitis: An atypical presentation.

remains the most important cause of bacterial meningitis worldwide. The second most common and potentially severe end-organ manifestation of invasive meningococcal disease is meningococcal pneumonia. It occurs between 5 % and 15 % of all patients with invasive meningococcal disease.

MicroRNA 26a Expression in Peripheral Blood Mononuclear Cells and Correlation with Serum Interleukin-17 in Relapsing-Remitting Multiple Sclerosis Patients.

Multiple sclerosis (MS) is a chronic multifocal inflammatory demyelinating disease. One of the main cells that play a crucial role in pathogenesis of MS is T helper 17 (Th 17). There are growing interests in nominating microRNAs in Th17 cell differentiation and suggesting new therapeutic modalities.

Entropy-guided end-tidal desflurane concentration during living donor liver transplantation.

Background: The three phases of living donor liver transplantation (LDLT) represent different liver conditions. The aim is to study the required end-tidal desflurane concentration (ET-Des) guided with entropy monitoring for the depth of anesthesia.

Methods: After the Ethics and Research Committee approval, 40 patients were included in this prospective study.
