Nosema ceranae, a microsporidium species, is among the most common causes of bee diseases. The positive effect Agaricus bisporus mushroom extract on survival and immunity Nosema-infected bees has been reported recently. could be achieved by stimulating expression immune-related genes, but also suppressing nosemosis. aim this work was to determine A. oxidative status infected with N. ceranae. In...

Globalization has provided opportunities for parasites/pathogens to cross geographic boundaries and expand to new hosts. Recent studies showed that Nosema ceranae, originally considered a microsporidian parasite of Eastern honey bees, Apis cerana, is a disease agent of nosemosis in European honey bees, Apis mellifera, along with the resident species, Nosema apis. Further studies indicated that ...
