PUCCIARELLI, Amada B; TESSARI, Alberto  and  VON SPECHT, Martha H. Enterococcus spp in water Vicario stream: Counts, identification and sensibility profiles. Rev. cienc. tecnol. [online]. 2014, n.21, pp.20-26. ISSN 1851-7587.

Enterococcus genus is a microorganism considered an indicator of fecal contamination of water and food; their presence in food is due to their ability to survive and their high resistance to different processes and treatment conditions. Enterococcus genus has relevance due to its high incidence in nosocomial illnesses and its property to acquire resistance to antimicrobials agents. The presence of Enterococcus species from Vicario stream water of Posadas City, Misiones, was studied. Detection, characterization and the biochemical profile was done according to the standard methods for water and streams, and sensibility assays to chemotherapeutic (Glucopeptids, Aminoglusides and ß-lactamics were done by the Clinical and Laboratory Standards Institute (CLSI). The strains were: 86% Enterococcus faecalis; 9% E. faecium; 1% E. hirae; 1% E. gallinarum; and 3% no enterococcus. A high sensibility towards antibiotics was observed, except three E. faecalis of which two presented high resistance to aminoglucosides and one with a medium resistance to vancomicine. These contaminants came from waste water considering the intestinal origin of isolated strains. The findings of this study are important for the control of antibiotic resistance in the environment.
