Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

iMetaOmics, Volume 3, Issue 1, March 2026.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

Deciphering the impact of endoparasitic infection on immune response and gut microbial composition of Channa punctata

Frontiers in Cellular and Infection Microbiology
Intestinal parasitic infections caused by helminths are globally distributed and are a major cause of morbidity worldwide. Parasites may modulate the virulence, gut microbiota diversity and host responses during infection.

Evidences That Host Genetic Background More Than the Environment Shapes the Microbiota of the Snail Bulinus truncatus, an Intermediate Host of Schistosoma Species

Molecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Microbiota have emerged as fundamental regulators of host physiology, shaping both ecological interactions and evolutionary trajectories. Yet, the determinants of microbiota diversity and structure in wild populations—particularly the respective roles of host genetics and environmental context—are still poorly understood.

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, Volume 13, Issue 10, 18 February 2026.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Wood Hemicellulose‐Based Spray‐Dried Microencapsulation of a Lytic Bacteriophage Preserves Phage Viability and Improves Control of the Bacterial Wilt Pathogen Ralstonia solanacearum

Microbial Biotechnology, Volume 19, Issue 2, February 2026.
Wood hemicelluloses derived from the forestry industry can be used to microencapsulate lytic bacteriophages for storage and application. Phages targeting the global bacterial wilt pathogen Ralstonia solanacearum were encapsulated in hemicelluloses that not only preserved them for long term storage but synergistically improved their anti‐Ralstonia ...

Challenging Evolutionary Paradigms: Daphnia Populations Resurrected From Unpolluted Environments Show Enhanced Detoxification Ability to Aromatic Pollutants

Molecular Ecology, Volume 35, Issue 4, February 2026.
ABSTRACT Understanding how organisms respond to chemical stress requires disentangling genetically encoded (constitutive) adaptations from environmentally induced (plastic) responses. This challenge is particularly acute for polycyclic aromatic hydrocarbons (PAHs), widespread aquatic pollutants with well‐documented toxicity, where mechanisms of ...

High‐Resolution Metabarcoding Reveals the Microbiome Dynamics of Mangrove Oysters (Crassostrea gasar) and Their Habitat

Marine Ecology, Volume 47, Issue 1, January/February 2026.
ABSTRACT The mangrove oyster (Crassostrea gasar) plays a key ecological role in Amazonian estuaries by filtering suspended organic particles, microalgae, phytoplankton, and bacteria, contributing to water quality and nutrient cycling. Its gut microbiota is shaped by complex interactions with the surrounding aquatic environment, reflecting the ...
