  • Disease caused by two species of microsporidian parasites which can infect drones, worker bees and queen bees
  • Spores germinate in the bee’s gut and may cause a declining hive population, poor honey production, reduced brood production and dysentery in and around the hive
  • Infection results in reduced colony health and performance, as well as heavy winter losses
  • Both species (Nosema apis and N. ceranae) are present throughout Australia, except N. ceranae is not present in WA
