a
The numbers within parentheses indicate the total number of distinctive colonial morphotypes tested that carried the specific ESBL gene.
b
All human and pig blaCTX-M-1-carrying isolates collected at 0 months were not tested for the presence of additional genes.
c
Within this farm the presence of the same ESBL genes was established in both pig farmers and their pigs on one or more sampling occasion(s).
