dc.description.abstract | Las actividades mineras realizadas durante varios siglos de manera ininterrumpida en el estado de Zacatecas han generado un problema de contaminación de suelos con metales y metaloides como el arsénico. En este estudio, se analizó la tolerancia al arsénico de diez aislados bacterianos observándose una alta tolerancia en medio sólido (40 mM – 300 mM de arseniato y 4 mM – 25 mM de arsenito) y en medio líquido (7.5mM – 12 mM de arsenito). Los aislados tolerantes a arsénico fueron identificados mediante análisis bioquímico y amplificación del gen ribosomal 16S (rDNA 16S) como miembros de los géneros Bacillus, Micrococcus y Acinetobacter. Un estudio de resistencia a antibióticos reveló alta prevalencia de la resistencia a beta-lactámicos y moderada a nitrofurantoína, vancomicina y ceftriaxona, sugiriendo que la multiresistencia a antibióticos de estos aislados podría estar relacionada a la tolerancia al arsénico mediante un mecanismo de resistencia presente en plásmidos o en el cromosoma | es_MX |

dc.description.abstractEnglish | Several centuries of uninterrupted mining activities in Zacatecas, Mexico has caused soil pol-lution with toxic metals and metalloids such as arsenic. In this study, the arsenic-tolerance of ten bacterial isolates from a metal contaminated site were analyzed, and high toler-ance was observed in both solid (40 mM – 300 mM of sodium dihydrogen arsenate and 4 mM – 25 mM of sodium arsenite) and liquid media (7.2 mM and 11.3 mM arsenite). The arsenic tolerant isolates were identified by biochemical and 16S rRNA-encoding gene am-plification analysis as members of the Bacillus, Micrococcus, and Acinetobacter genus. A study of resistance to antibiotics revealed a high prevalence of resistance to beta-lactams and moderate prevalence to nitrofurantoin, vancomycin, and ceftriaxone, suggesting that the antibiotic multiresistance of the isolates is probably related to arsenic tolerance through a plasmid or chromosomally encoded resistance mechanism | - |
