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 ...

A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

Effect of bodily fluids from honey bee (Apis mellifera) larvae on growth and genome-wide transcriptional response of the causal agent of American Foulbrood disease (Paenibacillus larvae).

PLoS ONE, 2014
Paenibacillus larvae, the causal agent of American Foulbrood disease (AFB), affects honey bee health worldwide. The present study investigates the effect of bodily fluids from honey bee larvae on growth velocity and transcription for this Gram-positive ...

Immune priming of honey bees protects against a major microsporidian pathogen

Pest Management Science, Volume 81, Issue 12, Page 7939-7949, December 2025.
We immune‐primed honey bees at two developmental stages in the laboratory and the field with heat‐killed Nosema ceranae spores. When subsequently fed live spores, immune‐primed adults had lower infection levels. Abstract BACKGROUND Honey bees face significant threats from pathogens like Nosema ceranae, a microsporidian parasite that contributes to ...

Antagonistic interactions between honey bee bacterial symbionts and implications for disease

BMC Ecology, 2006
Background Honey bees, Apis mellifera, face many parasites and pathogens and consequently rely on a diverse set of individual and group-level defenses to prevent disease. One route by which honey bees and other insects might combat disease is through the

Antimicrobial Activity of Phenolic Extract of Apple Pomace against Paenibacillus larvae and its Toxicity on Apis mellifera

Journal of Apicultural Science, 2020
Apis mellifera populations are exposed to different biotic and abiotic stressors that affect bee survival. Paenibacillus larvae, the causative agent of American foulbrood, is one of the most important bacterial pathogens that affect bee health.
