From: Emergence of β-lactamase- and carbapenemase- producing Enterobacteriaceae at integrated fish farms
Number of carbapenem- and cephalosporin- resistant Enterobacteriaceae isolates among outlet water. The Enterobacteriaceae isolates from outlet water (n = 16), including E. coli (n = 12), ECC (n = 2), and K. pneumoniae (n = 2) 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). 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
