Lysostaphin-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...
متن کاملSusceptibility of methicillin-resistant Staphylococcus aureus to lysostaphin.
One hundred and eleven isolates of methicillin-resistant Staphylococcus aureus recovered from patients at the Olin E. Teague Veterans Center from March 1983 to April 1987 were as susceptible to lysis by lysostaphin as methicillin-susceptible S. aureus controls were.
متن کاملLysostaphin in treatment of neonatal Staphylococcus aureus infection.
This study describes lysostaphin's effect against methicillin-sensitive Staphylococcus aureus in suckling rats. Standard techniques determined minimal inhibitory and bactericidal concentrations, pharmacokinetics, and efficacy. The numbers of surviving rats after vancomycin, oxacillin, and lysostaphin treatment were comparable and were different from that of controls (P < 0.00001). Lysostaphin a...
متن کاملRapid 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...
