Lysogenic conversion in Staphylococcus aureus to leucocidin production.
نویسندگان
چکیده
A Staphylococcus aureus strain was successively cured of three prophages. A lysogenic conversion by a group A phage to production of Panton-Valentine leucocidin and by a group F phage to staphylokinase production could be demonstrated.

Lysogenic conversion for multiple characters in a strain of Staphylococcus aureus.
Lysogenization of nonlysogenic strains of Staphylococcus aureus was performed with two different bacteriophages, LS1 and LS2, that were unable to plaque on any of the strains of S. aureus tested. Infection of recipient strains was achieved when protoplasts were inoculated with LS1 or LS2 or when bacterial cultures were simultaneously inoculated with a virulent phage together with LS1 or LS2. Ly...
متن کاملSuccess stories about severe pneumonia caused by Panton-Valentine leucocidin-producing Staphylococcus aureus.
We describe three cases of community-acquired necrotizing pneumonia which were caused by Panton-Valentine leucocidin-producing strains of Staphylococcus aureus (one of them methicillin sensitive). All cases were successfully treated without any sequelae for the patients due to the prompt initiation of adequate antimicrobial therapy. High suspicion toward this fatal pathogen was the key to the s...
متن کاملTransmission of a Panton-Valentine leucocidin-positive, methicillin-resistant Staphylococcus aureus strain between humans and a dog.
Panton-Valentine leucocidin-positive methicillin-resistant Staphylococcus aureus (MRSA) strains with identical resistance patterns were cultured from recurrent infections of a 51-year-old patient, her healthy husband, son, and dog, and pulsed-field gel electrophoresis showed that all MRSA strains were indistinguishable.
متن کاملPanton–Valentine leucocidin expression by Staphylococcus aureus exposed to common antibiotics
OBJECTIVES We set out to investigate the impact of common antibiotics on Panton-Valentine Leucocidin (PVL) expression by methicillin-sensitive Staphylococcus aureus (MSSA). PVL expression by methicillin-resistant S. aureus (MRSA) is reportedly enhanced by β-lactams, but inhibited by protein-synthesis inhibitors, a fact that has influenced management of infections associated with PVL. Although P...
متن کاملA brief history of Staphylococcus aureus Panton Valentine leucocidin
The history of Panton Valentine leucocidin (PVL), one of the toxins of Staphylococcus aureus, began in 1894, 24 years after Sir Alexander Ogston and Louis Pasteur had reproduced human pyemic infections in mice and rabbits by inoculating pus or pus-derived cultures (11,14). The torch of PVL research was then handed down over the decades between small groups of scientists fascinated by S. aureus ...
