Article Abstract
In this study, metagenomic analysis was employed to investigate the bacterial communities in the Muan tidal mudflat of the Republic of Korea. We used metagenomic analysis to identify the microbial community in tidal soil dominated by Proteobacteria. From this environment, the bacterial strain, sp. CMS18, was isolated and yielded two previously unknown compounds, penipaline D () and -acetyl-dimethylallyltryptophan (). The chemical structures of the isolated compounds along with 6-dimethylallyl-indole (), 6-dimethylallyltryptophan (), penipaline D (), and -acetyl-dimethylallyltryptophan () were structurally investigated using HR-ESI-MS and NMR spectroscopy. The isolated compound 6-dimethylallyl-indole () demonstrated broad-spectrum antifungal activity, with IC value of 0.04 mM against and 0.35 mM against both and . Additionally, it exhibited additive interaction with caspofungin against .

Black soldier fly (BSF) organic fertilizer is known to enhance soil fertility and promote plant growth. However, its effects on soil carbon (C) and nitrogen (N) cycling remains unclear. In this study, we established a BSF chicken manure bioconversion system to produce BSF organic fertilizer and investigate its impacts on soil C and N cycling, as well as microbial ecological networks through metagenomic analysis.

Objectives: This study aimed to evaluate the prognostic value of metagenomic next-generation sequencing(mNGS) using Nanopore sequencing technology (NST) versus traditional culture methods in infectious disease cases.
Methods: We conducted a retrospective, single-center observational study comparing clinical outcomes between patients and specimen types in NST group and those in culture-based control group. Cox Proportional Hazards regression and Kaplan-Meier survival analysis were conducted to evaluate the association between diagnostic strategy and 28-day mortality.

High rates of mortality of the common cockle, , have occurred in the Wash Estuary, UK, since 2008. A previous study linked the mortalities to a novel genotype of , with a strong correlation between cockle moribundity and the presence of . Here, we characterize a novel iridovirus, identified by chance during metagenomic sequencing of a gradient purification of cells, with the presence also correlated to cockle moribundity.

It is a gram-positive anaerobic bacteria or microaerobic filamentation bacteria, which can induce pyogenic and granulomatous inflammation characterized by swelling and concomitant pus, sinus formation, and the formation of yellow sulfur granules. All tissues and organs can be infected; the most common type involves the neck and face (55%), followed by the abdominal and pelvic cavities (20%).

Rationale: Japanese spotted fever (JSF) is a rare tick-borne disease caused by Rickettsia japonica. Atypical manifestations and a lack of standardized diagnostic assays often result in delayed diagnosis and treatment, potentially leading to life-threatening complications.
Patient Concerns: A 57-year-old immunocompetent female from a region with no previously reported JSF cases presented with acute-onset high-grade fever (39.
