Cefoxitin is a cephamycin antibiotic, classified as a second-gene

Cefoxitin is a cephamycin antibiotic, classified as a second-generation cephalosporin. The importance of testing with cefoxitin is also increased because it is routinely used as an oxacillin-surrogate

routinely for susceptibility testing [41] and MRSA phenotype prediction [60–64]. Cefepime is a fourth generation cephalosporin GSK1210151A cell line that is designed to have better stability against β-lactamases [56, 57]. Consistent with this, the β-LEAF assay accurately identified cefepime as the most resistant to the β-lactamase(s) in our experiments (Figure 3, Table 4). Interestingly, the cefazolin disk diffusion results indicated all isolates as cefazolin susceptible, while analyses from the β-LEAF assays predicted that cefazolin would be less active for five of the isolates (#1, #6, #18, #19, #20) (Table 2 – columns 5 and 6). At the same time, the zone edge test applied to disk diffusion plates [55] matched the β-lactamase prediction from both the nitrocefin tests and β-LEAF assay for these isolates (Table 2- columns 2, 3 and 4). Similarly, while the E-tests suggested isolates #1 and #6 to be cefoxitin susceptible (and #18, #19, #20 to have different degrees of resistance to cefoxitin) (Table 5), the β-LEAF assay predicted that cefoxitin could be inactivated by these isolates, by virtue of lactamase production (Figure 3).

is that the CLSI recommends performing tests to detect β-lactamase production on staphylococci for which BIX 1294 price penicillin zone diameters are ≥ 29 mm or MIC ≤ 0.12 μg/ml, before reporting isolates as susceptible [41, 42], which suggests that taking β-lactamase production into consideration additionally may be important. Thus, taken as a whole, the results of the standard tests and β-LEAF many are consistent when considering lactamase production along with disk diffusion or MIC results. By providing a rapid mode to test lactamase production as well as help predict antibiotic activity, the β-LEAF assay could prove to be advantageous and potentially minimize the need for additional testing. The overall agreement between standard CLSI recommended methodologies and the proposed assay in this work for β-lactamase detection and antibiotic activity/susceptibility is encouraging, particularly in view of the fact that β-LEAF assay provides these results from a rapid (1 h) assay. When validated with a large sample number, the assay could be adapted as a rapid diagnostic of antibiotic susceptibility, and serve as a useful adjunct in management of antibiotic resistance [10].
