Some fun facts on the Melissococcus plutonius are that it have a sour odour to it. It also have a scale which is rubbery, brown to black looking. It have a spotty brood pattern in a honey bee colony. It sometimes be melted in the cells and be mushy. The remaining part be slightly ropey with threads less then 1.5cm long. You can test the remains by sticking a tooth pick into the hole to see if its ropey looking.

Classification

Melissococcus plutonius

Domain: Bacteria

Phylum: Firmicutes

Class: Bacilli

Order: Lactobaillales

Family: Enterococcaceae

Genus: Melissococcus

Species: Melissococcus plutonius


Description and Significance

Melissococcus plutonius is a European foul brood that is an important disease of honey bees. It is found on conctinents where Apis mellifera is kept. In 1980, Bailey and Collins had reclassification of the European foul brood disease. It state that the plutonius infect the honeybee larvae in broadly separate parts. In 1982, they introduce the new reclassified name as Melissococcus pluton. Then 1998, Truper and Clari change the name to Melissococcus plutonius to meet the International Code of Zoological Nomenclature.

Genome

The M. plutonius DAT561 genome is a single circular chromosome with an average GC content of 31.5%. It also have 4 rRNA operons, 55 tRNA genes for all the amino acids, 18 pseudogenes, and the chromosome contain a total of 1,531 CDSs. They also have four incomplete prophages. The genome contain two plasmids and three pseudogenes were found in the pMP1 plasmid. The plasmids have an average GC content of 29.2% and 30.3%.

Cell Structure, Metabolism and Life Cycle

The M. plutonius is a prokaryotic cell.

Ecology and Known Roles in Symbiosis

Honey bees are important to agriculture but the European foul brood is very serious and infectious disease. The disease can cause problem with many things such as beekeeping industry and agricultural production. It can also effect the habitats because the impact that honeybees have on other animals. The will cause negative effect on the bee biodiversity.

Fun Facts

Some fun facts on the Melissococcus plutonius are that it have a sour odour to it. It also have a scale which is rubbery, brown to black looking. It have a spotty brood pattern in a honey bee colony. It sometimes be melted in the cells and be mushy. The remaining part be slightly ropey with threads less then 1.5cm long. You can test the remains by sticking a tooth pick into the hole to see if its ropey looking.
