For the first time, scientists have isolated the parasite Nosema ceranae (Microsporidia) from professional apiaries suffering from honey bee colony depopulation syndrome. They then went on to treat the infection with complete success. In a study published in the new journal from the Society for Applied Microbiology: Environmental Microbiology Reports, scientists from Spain analysed two apiaries and found evidence of honey bee colony depopulation syndrome (also known as colony collapse disorder in the USA). They found no evidence of any other cause of the disease (such as the Varroa destructor, IAPV or pesticides), other than infection with Nosema ceranae. The researchers then treated the infected surviving under-populated colonies with the antibiotic drug, flumagillin and demonstrated complete recovery of all infected colonies.
