Network analyses of COPGs within the genus Bifidobacterium. Network analyses based on the presence/absence of COPGs in each Bifidobacterium strain are indicated. White circles represent the 15 identified COPGs, each color denotes a different ecological niche, and the diameter is proportional to the number of total pilus loci (i.e., loci belonging to COPGs as well as unique pilus loci).
