Abstract

This study aimed to investigate the presence of enteric bacteria resistant to different antimicrobials in water wells constructed in the region of Santa Teresa and Santa Maria de Jetibá - ES. For they were collected samples from 10 wells and five wells of each city. These samples were subjected to laboratory tests for isolation and identification of bacteria and then the antibiogram for enterobacteria. In Santa Teresa 60% of the collected sites showed microbial contamination, as in Santa Maria de Jetibá, 80% of wells were contaminated. There was a prevalence of total coliform bacteria, such as Klebsiella pneumoniae, Enterobacter cloaceae, Enterobacter gergoviae and Serratia rubideae. Among the enterobacterial 33.4% were resistant to cephalothin and tetracycline and 16.7% to gentamicin. Groundwater microbial contamination, and even the presence of contaminants with antimicrobial resistance, indicates a considerable level of human interference in these ecosystems, highlighting the need for careful about how to use these waters, especially if it is being used in environments that deal with human health.
