Nosema causative agent?

Explanation:
Nosema disease in honey bees is caused by a microsporidian parasite that infects the bees’ midgut. The classic causative agent identified for this condition is Nosema apis, which produces spores that bees ingest, leading to gut damage, dysentery, reduced lifespan, and weaker colonies. While a related species, Nosema ceranae, can also infect honey bees, Nosema apis is the traditional cause emphasized in many exams. The other organisms listed are not Nosema: Acarapis woodi is a tracheal mite, and Ascosphaera apis is a fungus that causes chalkbrood.
