  1. a For egrets and whistling ducks, each sample is a pool of five different faecal samples collected on the field
  2. b 218/250 (cattle), 2/28 (egrets) and 22/24 (whistling duck) faecal samples that yielded no cefotaxime resistant isolates are not shown
  3. c Some faecal samples yielded more than one CREC resistant E. coli isolate
  4. d Number of E. coli isolates found resistant to cefotaxime after antimicrobial susceptibility testing of multiple bacterial colonies cultured from each sample on cefotaxime eosine methylene blue agar
