Alterations in phage-typing patterns in vancomycin-intermediate Staphylococcus aureus

Vancomycin-intermediate Staphylococcus aureus in Korea.

Recent reports on some methicillin-resistant Staphylococcus aureus (MRSA) with reduced susceptibility to vancomycin have been a major concern in Korea because of the widespread use of vancomycin due to a high prevalence of MRSA in the country. We describe a 45-year-old man with long-standing pelvic abscess due to MRSA. In spite of vancomycin and teicoplanin treatment for a long period of time, ...

Vancomycin Resistance in Staphylococcus aureus Strains

Molecular epidemiology of heteroresistant vancomycin-intermediate Staphylococcus aureus in Brazil.

To determine the epidemiological and molecular characteristics of 12 Staphylococcus aureus isolates presenting heteroresistance to vancomycin in laboratories of two cities in Santa Catarina, southern Brazil. Epidemiological data, including the city of isolation, health institution, and date of isolation were considered, as well as the associated clinical specimen. For molecular characterization...

Vancomycin-intermediate Staphylococcus aureus in a home health-care patient.

In June 2000, vancomycin-intermediate Staphylococcus aureus (VISA) was isolated from a 27-year-old home health-care patient following a complicated cholecystectomy. Two VISA strains were identified with identical MICs to all antimicrobials tested except oxacillin and with closely related pulsed-field gel electrophoresis types. The patient was treated successfully with antimicrobial therapy, bil...

Daptomycin Resistance in Vancomycin-Intermediate Staphylococcus Aureus Isolate

We describe a patient with methicillin-resistant Staphylococcus aureus (MRSA) who developed resistance to daptomycin, a new cyclic lipopeptide recently approved for the treatment of infections by gram-positive organisms. Development of resistance to daptomycin during prolonged use may occur with MRSA bacteremia
