And then there were three....a third Nosema species confirmed in Uganda

It is so important to be on top of disease, and the winter time lends itself to checking out new books on all aspects of beekeeping, let alone disease.  For anyone taking written bee exams, disease always features strongly, making up a minimum of one full question, often more. So candidates are encouraged to form study groups, practice exam questions and, at senior level, be up-to-date with the most recent research, particularly with respect to diseases and veterinary medicines and associated licensing laws, as well as documented use and secure storage of medicines.

In preparing for yet another exam, I found reference to a newly discovered species of the microsporidian, Nosema, which has been named Nosema neumanni.  For now, it appears to be limited to Apis mellifera in Uganda, but as is often the case with this kind of discovery, it may be the ever improving molecular techniques that has made it possible to distinguish this species from N. apis and N.cerana- it could be more widespread than we think. We are still coming to terms with Nosema caranae, and it was officially (publication year) announced in 2006- that's 12 years now!  It just goes to show how rapidly diseases can appear and spread and how  beekeepers have to stay well informed and adapt to new regimes in terms of disease control.
