Relative abundance of individual bacteriophages in different donor-recipient pairs. a Line graphs representing relative abundance of different individual bacteriophages in the recipients of donor 2—a novel Caudovirales and Microviridae—and b recipients of donor 3—CrAssphage and an unclassified viral contig. A donor timeline depicting the relative abundance the bacteriophage in question has also been included in each case, with the time of donation to each recipient marked therein. As donor 1 only had a single recipient, it was not possible to determine if differential colonisation patterns were associated with this donor
