Pangenome-Informed Long-Read Amplicons Enable High-Resolution Wheat Microbiome Profiling
Introduction: A new era of microbiome profiling in crops Understanding the microbial communities living on wheat leaves is crucial for crop health and yield. Traditional short-read ribosomal barcodes often miss fine-scale diversity within dominant phyllosphere taxa. A recent approach leverages pangenome-informed, taxon-specific long-read amplicons to achieve species- and strand-level resolution in real agricultural settings. Here,…

Phenotypic, Molecular Detection, and Antibiogram Analysis of Pseudomonas spp. in Nile Tilapia (Oreochromis niloticus) from Ethiopian Aquaculture Ponds
Overview Nile tilapia (Oreochromis niloticus) is a cornerstone of freshwater aquaculture worldwide thanks to its fast growth and adaptability. In Ethiopia, rapid expansion of tilapia farming in semi‑intensive and intensive systems has brought attention to fish health and food safety. This study investigates the presence, phenotypic traits, molecular detection, and antibiotic susceptibility of Pseudomonas spp.…

High-Resolution Plant Microbiome Profiling with Pangenome-Informed Long-Read Amplicons in Wheat Leaves
Introduction: elevating microbiome profiling in the wheat phyllosphere Understanding the complex microbial communities on wheat leaves is essential for disease management and crop health. Traditional ribosomal barcodes (16S/ITS) offer broad taxonomic coverage but often fall short in resolving closely related strains. A recently developed approach uses pangenome-informed, taxon-specific long-read amplicons to achieve species- and strain-level…

Pseudomonas Infections in Nile Tilapia (O. niloticus) from Ethiopian Aquaculture Ponds: Phenotypic, Molecular Detection, and Antibiogram
Overview Nile tilapia (O. niloticus) is a cornerstone of aquaculture in many countries, providing a reliable protein source. In Ethiopia, rapid growth of aquaculture has been accompanied by concerns about bacterial pathogens, particularly Pseudomonas spp., which can threaten yield and raise public health considerations due to antimicrobial resistance. A cross‑sectional study conducted from December 2022…

Phenotypic, Molecular Detection, and Antibiogram Analysis of Pseudomonas Species in Nile Tilapia (Oreochromis niloticus) from Ethiopian Aquaculture Ponds
Introduction Nile tilapia (Oreochromis niloticus) is a cornerstone of global aquaculture, prized for fast growth and adaptability. In Ethiopia, expanding aquaculture brings attention to bacterial pathogens that threaten productivity and public health. Among these, Pseudomonas spp. are ubiquitous Gram-negative bacteria capable of causing disease in fish and posing zoonotic risks. This article summarizes a study…

Raw cat food risks: health hazards for pets and families today
Summary: raw cat food risks highlighted by new research A new analysis of commercial raw cat foods — including products sold at room temperature and online — raises concerns about health risks to cats and the people who care for them. The study, published in Communications Biology, detected disease-causing microbes, some resistant to antibiotics, in…

Salt Stress and the Wild Soybean Microbiome: Rhizosphere vs. Surrounding Environment
Introduction: Why study salt stress and the soybean microbiome? Salt stress dramatically alters plant performance and microbial communities. In a controlled hydroponic system using Hoagland’s solution, researchers can isolate the direct effects of NaCl concentration on the rhizosphere (root-associated) and the surrounding water environment of wild soybean (Glycine soja) without the confounding variables of soil.…

Salt Stress Shapes Rhizosphere and Environmental Bacterial Communities in Wild Soybean (Glycine soja)
Introduction Wild soybean (Glycine soja) growing in coastal saline habitats relies on a complex microbiome to cope with salt stress. This study uses a hydroponic system with Hoagland’s solution to precisely control NaCl concentrations and to clearly separate rhizosphere bacteria from those in the surrounding water environment. By comparing a control (CK) with low (LT),…

Salt Stress Shifts Wild Soybean Rhizosphere Microbiome: A Comparative Study
Introduction and study design Understanding how salinity affects plant-associated microbial communities is essential for unraveling plant resilience mechanisms. This study used a controlled hydroponic system with Hoagland’s nutrient solution to isolate the effects of salt (NaCl) on bacterial communities in the rhizosphere of wild soybean (Glycine soja) and its surrounding water environment. Four treatments were…
