What life stage does American Foulbrood affect?

Explanation:
American Foulbrood targets honey bee brood in the very early larval stage. The disease is caused by Paenibacillus larvae spores, and infection occurs when very young larvae—typically within the first 24 to 48 hours after hatching—ingest contaminated brood food. At this early stage the larval gut is susceptible to spore germination and tissue damage, leading to death and the characteristic foul-smelling, ropy remains in the cell. As larvae age beyond the first couple days, they become much less susceptible, so eggs, older larvae, pupae, and adults are not the primary targets.
