Number of carbapenem- and cephalosporin- resistant Enterobacteriaceae isolates among fishpond water inlets and tap water. The Enterobacteriaceae isolates from a fishpond water inlets (n = 14), including E. coli (n = 9), ECC (n = 3), and K. pneumoniae (n = 2), as well as from b tap water (n = 33), including E. coli (n = 22), ECC (n = 6), and K. pneumoniae (n = 5) were screened for resistance against carbapenems (CRE) and cephalosporins (CEPH: FOX, CAZ, CTX, and CRO). The strains are grouped according to their resistance phenotypes as follow: CRE and all CEPH (isolates resistant to at least one of the tested carbapenems and all tested cephalosporins); CRE and 2 CEPH (isolates resistant to at least one of the tested carbapenems and two of the tested cephalosporins); CEPH (isolates resistant to 2 or more of the tested cephalosporins but not to carbapenems); CRE (isolates resistant to at least one of the tested carbapenems but not to any of the tested cephalosporins). Each phenotype is marked with colour and its resistance genotypes are also provided; carbapenemase (blaKPC, blaOXA-48, and blaNDM) and β-lactamase (blaCTX-M-15, blaSHV, blaOXA-1, blaTEM, and blaPER-1) genes. (n) represents numbers of resistant strains
