We studied the bacteriology of maxillary sinus aspirates obtained from patients diagnosed with chronic sinusitis. We recovered 659 strains from 510 aspirates; of these, 572 (86.8%) were aerobes and 87 (13.

[Detection of Enterococcus with high-level aminoglycoside and glycopeptide resistance in Lactuca sativa (lettuce)].

Background: The aim of this study was to assess the presence of enterococci highly resistant to aminoglycosides and glycopeptides in foods eaten uncooked, in order to evaluate their role as reservoirs of antimicrobial resistance.

Methods: We isolated 92 strains of enterococci from 79 samples of lettuce grown on farms near the city of Corrientes (Argentina). Enterococci were identified by standard methods.
