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 ...

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.

Reduction of Deformed Wing Virus-B levels in Colonies of the Honey bee Apis mellifera after Queen Vaccination with inactivated Paenibacillus larvae

bioRxiv
Deformed wing virus (DWV) is a virulent and ubiquitous disease that affects honey bee colonies. DWV infects bees at all life stages, but is most noticeable in adult bees, where clinical symptoms include shriveled, non-functional wings, and a drastically ...
