Cefsulodin Sodium Salt Hydrate is a third-generation cephalosporin antibiotic primarily used as a selective agent in microbiological research, particularly for the isolation and identification of Pseudomonas aeruginosa. Its application is critical in clinical diagnostics, where it aids in differentiating this pathogen from other bacteria in samples. Additionally, it is utilized in antibiotic susceptibility testing to evaluate the effectiveness of various antibiotics against resistant strains. In laboratory settings, it serves as a tool for studying bacterial resistance mechanisms and developing new antimicrobial strategies. Its role in research contributes significantly to understanding and combating infections caused by Pseudomonas species.
