SummaryIn this report, the pathological features observed in honey bees naturally infected with microsporidium Nosema ceranae throughout a year are described. The lesions produced under natural conditions similar to those experimentally caged worker bees. N. is able reproduce inside epithelial cells and multiply all through causing host-cells, characterized by progressive irreversible destruction of layer ventriculus, which can lead major negative repercussions on normal process digestion, critical consequences bee colony viability. It remarkable that factors such as continuous access fresh pollen around apiary or temperature humidity variations different seasons did not apparently influence development endogenous cycle parasite field conditions.
