Distribution of Melissococcus plutonius in Honeybee Colonies with and without Symptoms of European Foulbrood

Microbial Ecology, 2005
A sensitive hemi-nested polymerase chain reaction (PCR) was used for detection of Melissococcus plutonius, the causative agent of European foulbrood (EFB). Sampling was made in Switzerland, where EFB is a widespread disease and incidences have increased in recent years.

Preliminary investigations into possible resistance to oxytetracycline in Melissococcus plutonius, a pathogen of honeybee larvae

Letters in Applied Microbiology, 2003
To investigate the occurrence of oxytetracycline (OTC) resistance in Melissococcus plutonius, which causes European foulbrood in honeybee colonies.Strains of M. plutonius were isolated from diseased colonies in England and Wales and tested for resistance to OTC. The minimum inhibitory concentration (MIC) of OTC was also determined for selected isolates.

Different impacts of pMP19 on the virulence of Melissococcus plutonius strains with different genetic backgrounds

Environmental Microbiology, 2020
Summary Virulence factors responsible for bacterial pathogenicity are often encoded by plasmids. In Melissococcus plutonius , the causative agent of European foulbrood of honey bees, a putative virulence plasmid (pMP19) possessing mtxA

High‐level resistance of Melissococcus plutonius clonal complex 3 strains to antimicrobial activity of royal jelly

Environmental Microbiology Reports, 2017
Summary Melissococcus plutonius is the causative agent of European foulbrood of honey bee larvae. Among its three genetically distinct groups (CC3, CC12 and CC13), CC3 strains have been suggested to be more virulent at the colony level.

ความหลากหลายของแบคทีเรีย Melissococcus plutonius ที่ก่อโรคตัวอ่อนเน่ายูโรเปียน (European foulbrood disease) ในผึ้ง : รายงานผลการดำเนินงาน

2018
Melissococcus plutoniusเป็นแบคทีเรียก่อโรคตัวอ่อนเน่ายูโรเปียนในตัวอ่อนของผึ้ง เมื่อเร็ว ๆ นี้ พบว่าสามารถจัดจำแนกโซเลตของ M. plutoniusออกได้เป็น 2 ชนิด คือ typical M. plutoniusและ atypical M. plutoniusโดยทั้ง 2 ไอโซเลตมีลักษณะที่แตกต่างกันทั้งทางด้าน phenotype และพันธุกรรม ซึ่งแสดงให้เห็นว่าทั้ง 2 ไอโซเลตควรมีกลไกในการก่อโรคที่แตกต่างกันและส่งผลกระทบต่

Characterization ofMelissococcus plutoniuscausing European foulbrood disease inApis ceranaF.

Journal of Apicultural Research, 2012
SummaryApis cerana F. colonies were sampled over 12 months for the study of European foulbrood (EFB) in various regions of Himachal Pradesh, India. In EFB, death of brood is generally recorded in colonies in the pupal stage, but sometimes in the prepupal and larval stages. We found that the disease affected 6.18 to 18.56% of A. cerana colonies and 7.88

Prevalence, typing and phylogenetic analysis of Melissococcus plutonius strains from bee colonies of the State of Chihuahua, Mexico

Journal of Invertebrate Pathology, 2018
European foulbrood (EFB) caused by Melissococcus plutonius is an important bee brood disease but, in Mexico, information about this bacterium is limited. We evaluated the prevalence of typical and atypical strains in beehives of seven apicultural regions of the state of Chihuahua, Mexico.

The occurrence of Melissococcus plutonius in healthy colonies of Apis mellifera and the efficacy of European foulbrood control measures

Journal of Invertebrate Pathology, 2010
European foulbrood (EFB) persists in England and Wales despite current treatment methods, all of which include feeding honey bee colonies with the antibiotic oxytetracycline (OTC). A large-scale field experiment was conducted to monitor a husbandry-based method, using comb replacement (known as Shook swarm), as a drug free EFB control option.

A novel gold nanoparticles‐based assay for rapid detection of Melissococcus plutonius, the causative agent of European foulbrood

Veterinary Record, 2012
European foulbrood (EFB) is a severe bacterial brood disease of honey bees ( Apis mellifera ) caused by Melissococcus plutonius . Diagnosis of EFB in the field is based on visual inspection of brood‐combs and detection of diseased larvae.

Melissococcus plutonius jako původce hniloby včelího plodu

2018
European foulbrood is a bacterial disease attacking honey bee larvae worldwide. It is caused by bacterium Melissococcus plutonius, which is a non-spore-forming, Gram positive, anaerobic bacterium. The adult bees are not affected but serve as a vector of the disease as they carry the bacterium within their own bodies and can travel big distances from ...
