Virulence of Melissococcus plutonius and secondary invaders associated with European foulbrood disease of the honey bee [PDF]

MicrobiologyOpen, 2019
European foulbrood is a globally distributed brood disease affecting honey bees. It may lead to lethal infections of larvae and, in severe cases, even to colony collapse.

A high-throughput sequencing survey characterizing European foulbrood disease and Varroosis in honey bees [PDF]

Scientific Reports, 2023
As essential pollinators of ecosystems and agriculture, honey bees (Apis mellifera) are host to a variety of pathogens that result in colony loss. Two highly prevalent larval diseases are European foulbrood (EFB) attributed to the bacterium Melissococcus

Evaluating approved and alternative treatments against an oxytetracycline-resistant bacterium responsible for European foulbrood disease in honey bees [PDF]

Scientific Reports, 2022
European foulbrood (EFB) is a disease of honey bee larvae caused by Melissococcus plutonius. In North America, oxytetracycline (OTC) is approved to combat EFB disease though tylosin (TYL) and lincomycin (LMC) are also registered for use against American ...

Are fungicides a driver of European foulbrood disease in honey bee colonies pollinating blueberries?

Frontiers in Ecology and Evolution, 2023
IntroductionBlueberry producers in Canada depend heavily on pollination services provided by honey bees (Apis mellifera L.). Anecdotal reports indicate an increased incidence of European foulbrood (EFB), a bacterial disease caused by Melissococcus ...

Effects of essential oils on foulbrood bacteria and honey bee workers (Apis mellifera) under laboratory conditions [PDF]

Frontiers in Insect Science
IntroductionAmerican and European foulbrood diseases (AFB and EFB, respectively) result in considerable economic losses for beekeepers. Currently, no satisfactory methods are available for the treatment of either disease. There has been a recent surge of

Putative determinants of virulence in Melissococcus plutonius, the bacterial agent causing European foulbrood in honey bees

Virulence, 2020
Melissococcus plutonius is a bacterial pathogen that causes epidemic outbreaks of European foulbrood (EFB) in honey bee populations. The pathogenicity of a bacterium depends on its virulence, and understanding the mechanisms influencing virulence may ...

Sacbrood viruses and select Lake Sinai virus variants dominated Apis mellifera colonies symptomatic for European foulbrood [PDF]

Microbiology Spectrum
European foulbrood (EFB) is a prevalent disease in the European honey bee (Apis mellifera) in the United States, which can lead to colony decline and collapse. The bacterial components of EFB are well-studied, but the diversity of viral infections within
