Antimicrobial resistance profiles of salmonella spp. and escherichia coli isolated from fresh nile tilapia (oreochromis niloticus) fish marketed for human consumption

Table 4 Resistance and ESBL production test results of MDR Salmonella spp. and E. coli isolates

Microorganism	Isolate ID code	Antibiotic resistance	ESBL production
Salmonella spp.	Isolate ID code
	WES-09	CPD + RIF + S + VA	Positive
	MAK-22	AX + NIT + P + RIF + VA	Positive
	EMB-32	AX + CAZ + C + MRP + VA	Positive
E. coli
	MAK-26	AX + MRP + RIF + VA	Positive
	LAN-35	AX + MRP + RIF + VA	Positive

AX = Ampicillin/Cloxacillin; CPD = Cefpodoxime; CAZ = Ceftazidime; C = Chloramphenicol; MRP = Meropenem; NIT = Nitrofurantoin; P = Penicillin-G; RIF = Rifampicin; S = Streptomycin; VA = Vancomycin. The classes of antibiotics are: Carbapenems (MRP), Cephalosporin (third generation; CAZ), Penicillin (P-G), Beta-lactam (AX), Cephalosporin (third generation; CPD), Phenicol (C), Nitrofurans (NIT), Glycopeptides (VA), Ansamycin (RIF), and Aminoglycosides (S). ESBL, Extended-spectrum β-lactamase. Positive means that the bacteria produce extended-spectrum β-lactamases, which make them resistant to beta-lactamase antibiotics.
