The bacterial pathogen Xanthomonas oryzae pv. is the causative agent of the severe disease, bacterial leaf streak (BLS), in rice. The rice pest oryzicola (Xoc) has, over time, risen to become the fourth most prominent rice disease in some regions of southern China. A previously isolated Bacillus velezensis strain, 504, showed antagonistic properties against the Xoc wild-type strain RS105, indicating a potential as a biocontrol agent for BLS. Nonetheless, the intricate mechanisms of antagonism and biocontrol are not fully elucidated. Using genomic data from B. velezensis 504, coupled with comparative transcriptomic data from Xoc RS105 treated with cell-free supernatants (CFSs) of B. velezensis 504, we determine differentially expressed genes (DEGs). B. velezensis 504 showcases a high degree of gene conservation, exceeding 89%, compared to FZB42 and SQR9, both representative B. velezensis strains. However, the evolutionary relationship suggests a closer connection between 504 and FZB42 than with SQR9. Crucially, B. velezensis 504 also possesses the genetic machinery needed to produce difficidin and bacilysin, the essential anti-Xoc compounds. The results of our study indicate that approximately 77% of Xoc RS105 coding sequences are differentially expressed by the cell-free supernatants (CFSs) of Bacillus velezensis 504. This significant downregulation impacts genes in key cellular processes such as signal transduction, oxidative phosphorylation, transmembrane transport, cell motility, cell division, and DNA translation, as well as five metabolic pathways. Furthermore, a suite of virulence genes for type III secretion, type II secretion, type VI secretion, type IV pilus, lipopolysaccharides, and exopolysaccharides are impacted. B. velezensis 504 exhibits substantial potential as a biocontrol agent, effectively managing bacterial blight in rice with control efficiencies exceeding 70% in two susceptible rice cultivars. This strain also demonstrates antagonistic activity against key fungal pathogens, including Colletotrichum siamense and C. australisinense, the prevalent species responsible for leaf anthracnose in rubber trees across Hainan province, China. B. velezensis 504 possesses characteristics reminiscent of plant growth-promoting rhizobacteria, specifically including the secretion of protease and siderophore, further supported by the observed stimulation of plant growth. Investigations into the biocontrol mechanisms of *Bacillus velezensis* on BLS are revealed by this study, while also suggesting *Bacillus velezensis* 504 as a versatile plant probiotic.

Despite the development of newer drugs, Klebsiella pneumoniae continues to be a major global healthcare threat, and polymyxins remain a crucial therapeutic option, not just for it but also other resistant gram-negative pathogens. When it comes to testing polymyxins, broth microdilution is the single, recommended method. Our study investigated the accuracy with which a commercial Policimbac plate determines the polymyxin B MIC for clinical isolates of K. pneumoniae. Evaluation of the results involved comparing them to data from the broth microdilution method, adhering to the stipulations of ISO 16782. In spite of a high 9804% categorical agreement, the Policimbac plate unfortunately suffered from an unacceptable 3137% essential agreement rate. Observation revealed almost 2% of major errors. Interestingly, 5294% of the strains demonstrated an elevated MIC measurement at the 1 gram per milliliter level. The analysis excluded three isolates due to the drying of the Policimbac plate. In order to prevent the samples from drying out, wet gauze was strategically used in the test, resulting in a perfect categorical agreement rate of 100%; however, the essential agreement rate was disappointingly low at 2549%. In the end, the Policimbac plate failed to provide a correct polymyxin B MIC for the K. pneumoniae isolates tested. Substandard drug performance could obstruct its intended clinical use, subsequently jeopardizing the success of the patient's treatment.

Glioblastoma (GBM), a relentlessly aggressive cancer, presents a grim prognosis characterized by a median survival time of only approximately 15 months when treated with standard therapies like surgery, radiation, and chemotherapy, a figure that has remained largely unchanged over many decades. The cellular complexity of GBM is noteworthy, with glioblastoma stem-like cells (GSCs) at the highest level of differentiation.
