Lysostaphin aseptically filled is primarily used in medical and research applications due to its potent antibacterial properties. It is particularly effective against Staphylococcus aureus, including methicillin-resistant strains (MRSA), making it valuable in treating infections caused by these bacteria. In clinical settings, it is employed as a topical treatment for skin infections, wound care, and as an adjunct therapy to enhance the efficacy of conventional antibiotics. In research, lysostaphin is utilized to study bacterial cell wall structure and function, as it specifically cleaves the pentaglycine cross-bridges in the peptidoglycan layer of Staphylococci. This property also makes it a useful tool in microbiology for isolating DNA or proteins from Staphylococcus species. Additionally, it is being explored in biotechnological applications, such as developing antimicrobial coatings for medical devices to prevent biofilm formation. Its aseptic filling ensures sterility, making it suitable for direct use in sensitive applications.
