Oxytetracycline resistance of Melissococcus plutonius strains in Japan

Journal of Apicultural Research, 2023
European foulbrood caused by the Gram-positive lanceolate coccus, Melissococcus plutonius, is a major bacterial infection of honey bee brood. Oxytetracycline (OTC) has been used to combat this disease in some countries. Although OTC resistance was not previously reported despite its long-term use, the first case was finally detected in an M.

Potential confounding factors in currently used antibiotic susceptibility assays for the honey bee pathogen <i>Melissococcus plutonius</i>. [PDF]

J Med Microbiol
Introduction. Melissococcus plutonius is the causative agent of European foulbrood (EFB), a disease of honey bees that is endemic in many areas of the USA. Only one antibiotic, oxytetracycline (OTC), is approved for EFB management, and there have been reports of recalcitrance.

Bacterial community associated with worker honeybees (Apis mellifera) affected by European foulbrood [PDF]

PeerJ, 2017
Background Melissococcus plutonius is an entomopathogenic bacterium that causes European foulbrood (EFB), a honeybee (Apis mellifera L.) disease that necessitates quarantine in some countries. In Czechia, positive evidence of EFB was absent for almost 40

Molecular epidemiology and population structure of the honey bee brood pathogen Melissococcus plutonius. [PDF]

ISME J, 2014
AbstractMelissococcus plutonius is the causative agent of European foulbrood (EFB), which is a serious brood disease of the European honey bee (Apis mellifera). EFB remains a threat because of a poor understanding of disease epidemiology. We used a recently published multi-locus sequence typing method to characterise 206 M. plutonius isolates recovered

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 ...

Complete Genome Sequences of Two Melissococcus plutonius Strains with Different Virulence Profiles, Obtained by PacBio Sequencing. [PDF]

Microbiol Resour Announc, 2019
Melissococcus plutonius attacks honeybee larvae, causing European foulbrood. Based on their virulence toward larvae, M. plutonius isolates were classified into three types, highly virulent, moderately virulent, and avirulent.

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

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 ...

Development of duplex PCR assay for detection and differentiation of typical and atypical Melissococcus plutonius strains. [PDF]

J Vet Med Sci, 2014
Melissococcus plutonius is the causative agent of an important honeybee disease, European foulbrood (EFB). In addition to M. plutonius strains with typical characteristics (typical M. plutonius), we recently reported the presence of atypical M. plutonius, which are phenotypically and genetically distinguished from typical M. plutonius.

In Vitro Effects of Pesticides on European Foulbrood in Honeybee Larvae

Insects, 2020
Neonicotinoid and fungicide exposure has been linked to immunosuppression and increased susceptibility to disease in honeybees (Apis mellifera). European foulbrood, caused by the bacterium Melissococcus plutonius, is a disease of honeybee larvae which ...
