Rapid identification of Staphylococcus aureus by using lysostaphin sensitivity.
Lysostaphin sensitivity was evaluated as a rapid screening test to differentiate Staphylococcus aureus from other species of staphylococci and micrococci. A total of 168 strains of staphylococci, 108 of which were S. aureus, were cultured overnight in brain infusion broth. Gram stains were peformed before and after a 1:10 dilution of the culture was exposed to 2 micrograms of lysostaphin per ml...
متن کاملDirect observation of Staphylococcus aureus cell wall digestion by lysostaphin.
The advent of Staphylococcus aureus strains that are resistant to virtually all antibiotics has increased the need for new antistaphylococcal agents. An example of such a potential therapeutic is lysostaphin, an enzyme that specifically cleaves the S. aureus peptidoglycan, thereby lysing the bacteria. Here we tracked over time the structural and physical dynamics of single S. aureus cells expos...
متن کاملLysostaphin-induced, osmotically fragile Staphylococcus aureus cells.
Staphylococcus aureus FDA 209P cells when suspended in 24% (w/v) NaCl were rendered osmotically fragile by exposure to lysostaphin for time intervals ranging from 2 to 60 min. Such cells were analyzed chemically and serologically for evidence of residual cell wall material, were plated in hypertonic sucrose medium to determine revertibility to normal, and were subjected to manometric studies to...

کلونینگ، بیان، خالص سازی و ارزیابی آنزیم لیزواستافین نوترکیب با استفاده از سیستم کلونینگ pBAD
Background and purpose: Staphylococcus aureus is an important nosocomial pathogen which causes some diseases such as endocarditis, osteomyelitis, pneumonia, toxic shock syndrome, and food poisoning. The excessive and inappropriate use of antibiotics in the treatment of these diseases causes resistance to many antibiotics. Lysostaphin is an effective agent in the treatment of staphylococcal infe...
