Collection of honey bee microbial pathogens

Honigbiene, Wabe, Larven

The collection in brief

The collection has been built up as part of research projects carried out since 2006, focusing mainly on the bee larvae disease caused by Melissococcus plutonius (Figure 1). The collection currently comprises 180 isolates, exclusively bacteria of the Paenibacillus (20 isolates) and Melissococcus (160 isolates) genera. The vast majority of strains (167) were isolated from Swiss beehives, but the collection also contains a few reference strains (7) from international collections, as well as a few strains isolated abroad (6).
