Featured Case Study

Visualizing Pseudomonas aeruginosa and Staphylococcus aureus with the MolecuLight

Visualizing Pseudomonas aeruginosa and Staphylococcus aureus with the MolecuLight i:X led to optimized sampling

An infection is a serious complication of a foot ulcer and requires immediate treatment. Since not all infections are treated the same way, accurate sampling is critical to identify the causative pathogens, and ensure appropriate treatment selection.
