Genetically diverse colonies are host to more active, potentially probiotic genera and fewer potentially pathogenic genera.

Number of sequences in bee guts sampled from genetically uniform and genetically diverse colonies, classified into potential pathogenic and probiotic genera. Total number of sequences sampled for each colony type is given in parentheses in the header bar, and fraction of colonies sampled that had these pathogenic or probiotic genera is in parentheses for each genus. The same 7 genetically uniform and 5 genetically diverse colonies had these pathogens present (i.e., a colony either had all three pathogens in it, or none of them).
