Paenibacillus larvae is the etiological agent of American foulbrood (AFB) in honeybees. Recently, different genotypes of P. larvae (ERIC I to ERIC IV) were defined, and it was shown that these genotypes differ inter alia in their virulence on the larval level. On the colony level, bees mitigate AFB through the hygienic behavior of nurse bees. Therefore, we investigated how the hygienic behavior shapes P. larvae virulence on the colony level. Our results indicate that P. larvae virulence on the larval level and that on the colony level are negatively correlated.
