^aManure compost (MC) samples are identified by the day of sampling, e.g., MC-0 indicates manure compost at day zero.

^bCjej, C. jejuni; Cfet, C. fetus; Chyo, C. hyointestinalis; Abut, A. butzleri; and Cspp, unidentified Campylobacter species. No C. coli or C. lanienae isolates were recovered.

^cThe total number of campylobacteria isolates recovered and identified from manure in pens and compost was 144 (49 isolates from pen manure and 95 isolates from compost).
