Selective Testing for Beta-Lactamase Activity Antibiotics are often the only effective treatment for severe illnesses caused by microorganisms. Therefore, bacterial antibiotic resistance poses a significant threat to public health worldwide. An important resistance mechanism is enzymatic drug inactivation by extended-spectrum beta-lactamases (ESBLs) and carbapenemases. These bacterial enzymes deactivate β-lactam antibiotics by hydrolyzing the antibiotics’ β-lactam ring. The MBT Compass STAR-BL software module enables fast and accurate analysis of the level of β-lactamase activity in...

A Fast and Simple Workflow To determine the level of p-lactamase activity in a bacterial culture, samples from overnight cultures or positive blood cultures are incubated in an antibiotic solution. After incubation and centrifugation, cell-free supernatant is spotted onto a MALDI target plate and overlaid with matrix. Spectra are then acquired using the MALDI Biotyper. In cultures where no p-lactamase activity is present, peaks corresponding to the intact antibiotic will be present in the mass spectrum. In cultures where P-lactamase activity is present, peaks corresponding to hydrolyzation...
