Nosema ceranae is a microsporidian parasite that primarily infects honeybees, particularly the Apis cerana species. It affects the digestive system of bees, leading to reduced nutrient absorption and overall health decline. Infected bees may exhibit symptoms such as dysentery, decreased lifespan, and impaired foraging abilities. This parasite has gained attention due to its role in the decline of honeybee populations worldwide. Nosema ceranae can spread rapidly within colonies, especially under stressful conditions. Effective management practices, including maintaining hive health and monitoring for signs of infection, are essential for beekeepers to mitigate its impact.
