  1. a maximum numbers of isolates of one clone in one sample, as we included 20 isolates of one sample there was a theoretical range between 0 and 20 isolates per clone
  2. b total numbers including all isolates from all samples of one clone, as we included 800 isolates from all piglets over the whole eight week period and detected 44 clones a theoretical range between 1 and 757.
  3. c numbers of colonized piglets with a specific clone, as we included five piglets a theoretical range between 0 and 5
  4. d numbers of time points of the detection of a specific clone, as we sampled over an eight week period a theoretical range between 1 and 8
  5. * median (min/max)
