MELISSOCOCCUS
PLUTONIUS

 

 

Melissococcus plutonius is a bacterial infection that affects honeybee larvae. The disease is also known as European foulbrood, but it is distinct from the other form of foulbrood caused by the bacterium Paenibacillus larvae. Melissococcus plutonius can be a serious problem for beekeepers, as it can lead to the death of entire colonies if left untreated.

​

Symptoms: The symptoms of Melissococcus plutonius infection are similar to those of other forms of foulbrood. Infected larvae appear greasy and discolored, with a foul odor. The larvae may also die and turn brown or black, with a melted or shriveled appearance. In severe cases, the disease can spread to adult bees, causing a decline in the overall health of the colony.

​

Treatments: There are several treatments for Melissococcus plutonius infection. One option is to remove infected brood from the colony and burn it to prevent the spread of the disease. Antibiotics, such as oxytetracycline, can also be used to treat infected colonies. Beekeepers should consult with a veterinarian or experienced beekeeper to determine the best course of action.

​

Prevention Measures: Preventing Melissococcus plutonius infection is the best strategy to avoid the disease. Here are some prevention measures beekeepers can take:

​

Hygiene: Keeping hives clean and free from debris can help prevent the spread of bacteria. Beekeepers should also avoid sharing equipment between colonies to reduce the risk of contamination.

​

Monitoring: Regularly inspecting colonies for signs of disease can help catch infections early and prevent their spread to other colonies.

Nutrition: Providing bees with a healthy diet can help strengthen their immune systems and reduce their susceptibility to infection.

 

Queen Quality: Maintaining healthy queens can help produce strong colonies that are more resistant to disease.

​

Antibiotic Use: In some cases, prophylactic antibiotic treatments may be recommended to prevent the spread of infection. However, overuse of antibiotics can lead to antibiotic-resistant strains of bacteria, so they should only be used when necessary and under the guidance of a veterinarian or experienced beekeeper.

​

Melissococcus plutonius infection can be a serious problem for honeybee colonies. However, with proper hygiene, monitoring, nutrition, queen quality, and judicious use of antibiotics, beekeepers can help prevent the spread of the disease and protect their colonies. Beekeepers should also be vigilant for signs of infection and seek professional advice if they suspect their colonies may be affected.
