All strains produced ?-lactamase and were resistant to penicillin and dicloxacillin, showing single peak for minimum inhibitory concentration (MIC) distributions at 2000-4000 µg/mL and 500-1000 µg/ml, respectively. Ampicillin MIC distribution was bimodal with 20% resistant strains (125-250 µg/ml) and 80% highly resistant ones (500-4000 µg/ml). All strains were susceptible to ceftriaxone (MIC= 3.9 µg/ml) and all but one were susceptible to cefuroxime (3.9 µg/ml and 62.5 µg/ml). All strains had a single MIC distribution pattern for lead (800-3200 µg/ml), and mercury (20 µg/ml) and were considered resistant and susceptible to these ions, respectively. Fifteen percent of the isolates were resistant to arsenite (MIC= 400-800 µg/ml) and all were susceptible to silver (MIC= 1.25-2.5µg/ml), chromate (MIC= 93.5-375 µg/ml), and zinc (MIC=21.25-42.5 µg/ml).}, number={1}, journal={HIDROBIOLÓGICA}, author={Luz Paniagua, Gloria and Monroy, Eric and Perches, Magdalena and Negrete, Erasmo and García, Octavio and Vaca, Sergio}, year={2017}, month={ene.}, pages={75–79} }
