DELPECH, Gastón et al. Enterococcus spp. isolated from goat cheese: resistance to clinically used antimicrobials. Rev. Soc. Ven. Microbiol. [online]. 2013, vol.33, n.2, pp.129-133. ISSN 1315-2556.

In vitro resistance to clinically used antimicrobials was investigated in Enterococcus spp. isolated from goat cheese. The gentamycin, streptomycin, vancomycin, teicoplanin, ampicillin, imipenem, linezolid and tigecyclin minimum inhibitory concentration (MIC) was determined. Β-lactamase production was detected and conjugation experiments were carried out for transferring gentamycin resistance. In one E. faecalis and in 10 E. faecium isolates there was ampicillin resistance and β-lactamase production was demonstrated in one E. faecalis. Fifteen E. faecalis were imipenenem resistant; 4 linezolid resistant and 5 glucopeptide resistant. There was a high level of plasmidic resistance to tigecyclin in 4 E. faecalis isolates. There were no tigecyclin resistant isolates. Goat cheese is a reservoir of resistant enterococci with potencial human dissemination through the food chain.
