L-Tenuazonic Acid, a New Inhibitor of Paenibacillus Larvae

World Journal of Microbiology and Biotechnology, 2004
A search for bioactive compounds, inhibitors of Paenibacillus larvae, the causal agent of American foulbrood, a honeybees' disease, was carried on. Extracts of two fungal strains, Alternaria brassicicola and Alternaria raphani, isolated from pollen collected from beehives, exhibited a specific inhibitory activity against this bacterium.

Complete Genome Sequences of Five Paenibacillus larvae Bacteriophages

Genome Announcements, 2013
ABSTRACT Paenibacillus larvae is a pathogen of honeybees that causes American foulbrood (AFB). We isolated bacteriophages from soil containing bee debris collected near beehives in Utah. We announce five high-quality complete genome sequences, which represent the first completed genome sequences submitted to GenBank ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Anthraquinones From Epicoccum sp., a Fungus Isolated From Gut of Dione juno That Feeds on Passifloras

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
An Epicoccum fungus was isolated from gut of larvae of the butterfly Dione juno juno that feeds intensively on leaves of Passifloras. This fungus produces hydroxyanthraquinones that moderately inhibits growth of some Bacillus that coexist with the fungus in the insect gut, suggesting that it is probably important for microbial embalance in gut flora ...

Reclassification, genotypes and virulence of Paenibacillus larvae, the etiological agent of American foulbrood in honeybees – a review

, 2006
American foulbrood, a worldwide bacterial disease of honeybee brood caused by the gram-positive bacterium Paenibacillus larvae, is one of the most serious bee diseases. This review will focus on recent achievements in the study of Paenibacillus larvae

Wake Up and Smell the Infected Bees: Volatile Cues of Vairimorpha Infection in Honey Bees

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Infection can modify host volatile emissions, yet effects in adult honey bees remain unexplored. Using dynamic headspace sampling and GC × GC–MS, we show that Vairimorpha spp. infection significantly alters the volatile profile of adult worker honey bees over a 14‐day time series, producing stage‐specific shifts in multivariate odour structure.

Biological Role of Paenilarvins, Iturin-Like Lipopeptide Secondary Metabolites Produced by the Honey Bee Pathogen Paenibacillus larvae. [PDF]

PLoS ONE, 2016
The Gram-positive bacterium Paenibacillus larvae (P. larvae) is the causative agent of a deadly honey bee brood disease called American Foulbrood (AFB). AFB is a notifiable epizootic in most countries and, hence, P.

Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a Bacillus thuringiensis‐Based Biopesticide

Ecology and Evolution, Volume 16, Issue 6, June 2026.
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee
