Penetration of antibiotics through Staphylococcus aureus and Staphylococcus epidermidis biofilms
Open accessAbstract
OBJECTIVES: This study was carried out to elucidate the role of reduced antibiotic penetration in the resistance of Staphylococcus aureus and Staphylococcus epidermidis biofilms to different antibiotics. METHODS: The biofilms of S. aureus ATCC 29213 and S. epidermidis ATCC 35984 were grown on black, polycarbonate membranes (diameter, 13 mm; pore size, 0.4 microm) placed on tryptic soy agar plates at 37 degrees C for 48 h. The penetration of oxacillin, cefotaxime, amikacin, ciprofloxacin and vancomycin through the biofilms was determined by measuring the diameter of zones of growth inhibition (of S. aureus ATCC 25923, a quality control strain) on Mueller-Hinton agar plates following diffusion of each antibiotic from an overlying antibiotic disc through the biofilm to the agar medium versus the respective control assemblies. RESULTS: The penetration of oxacillin and cefotaxime (beta-lactams) and vancomycin (a glycopeptide) was significantly reduced through S. aureus and S. epidermidis biofilms whereas that of amikacin (an aminoglycoside) and ciprofloxacin (a fluoroquinolone) was unaffected. CONCLUSIONS: The results of this study indicate that the role of reduced antibiotic penetration in the drug resistance of S. aureus and S. epidermidis biofilms may vary with the antibiotic being used.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
