Fecha de publicación: | sep-2019 | Editor: | Elsevier | Citación: | Diagnostic Microbiology and Infectious Disease 95(1): 1-4 (2019) | Resumen: | The SuperLinezolid medium was developed for screening resistance to linezolid (LZD) in Gram-positive bacteria (Staphylococcus spp., Enterococcus spp.). It was evaluated using LZD-susceptible (n = 20) and LZD-resistant (n = 17) Gram-positive isolates. The sensitivity was found to be 82% at 24 h (3 out of 17 isolates being missed), and reached 100% at 48 h. At 48 h, a single LZD-susceptible isolate grew (specificity 95%). By testing stools spiked with LZD-resistant Gram-positive strains, an excellent performance of the medium was observed, with a lowest detection limit ranging from 101 to 102 CFU/ml. Overall, this medium is accurate for detection of LZD-resistant Gram-positive isolates after 24 h of culture. | Versión del editor: | http://dx.doi.org/10.1016/j.diagmicrobio.2019.03.006 | URI: | http://hdl.handle.net/10261/213136 | DOI: | 10.1016/j.diagmicrobio.2019.03.006 | ISSN: | 0732-8893 | E-ISSN: | 1879-0070 |
