  1. Isolates were cultured from rectal swabs collected within the first 14 days after insertion to the nursery unit, and tested for F18 and F4, and STa, STb and LT
  2. aAll isolates including both systematically sampled pigs and samples from diarrhea cases
  3. bPCR results from 34 samples, where hemolytic E. coli was deemed dominant were missing. Of these, 13 were from new cases of diarrhea
