Resistance to antimicrobial drugs is increasing at an alarming rate among both gram-positive and gram-negative bacteria. Traditionally, bacteria resistant to multiple antimicrobial agents have been restricted to the nosocomial environment. A disturbing trend has been the recent emergence and spread of resistant pathogens and resistance traits in nursing(More)
Three vancomycin-dependent clinical isolates of Enterococcus faecalis of the VanB type were studied by determining (i) the sequence of the ddl gene encoding the host D-Ala:D-Ala ligase and the vanSB-vanRB genes specifying the two-component regulatory system that activates transcription of the vanB operon, (ii) the level of expression of resistance genes by(More)
PURPOSE Although home parenteral antimicrobial therapy has become common, few studies have carefully examined its adverse effects. SUBJECTS AND METHODS We retrospectively reviewed the medical records of 269 patients who received 291 courses of home parenteral antimicrobial therapy through a hospital-based home infusion program during a 2-year period.(More)
OBJECTIVE To characterize the nutritional requirements and potential origin of a fastidious urinary tract Enterococcus faecalis isolate that apparently requires the antimicrobial agent vancomycin to grow. DESIGN Case report and detailed microbiologic and molecular epidemiologic analysis. SETTING University teaching hospital. MEASUREMENTS Growth of the(More)
Listeria monocytogenes is a Gram-positive bacillus that is pathogenic in both the normal and compromised host. We describe Listeria peritonitis and cerebritis in a patient with cirrhosis due to non-A, non-B hepatitis, and review the 11 other cases of Listeria peritonitis reported in the English-language literature. Listeria is a rare cause of peritonitis in(More)
Appropriately designed antibiotic regimens are critical to the management of all stages of osteomyelitis, although goals of therapy may vary in different stages of infection. The most important consideration for antibiotic selection is spectrum of action. Route of administration by intravenous or oral route is less important than drug levels that are(More)
Quinolone antimicrobial agents are known to interact with DNA gyrase, but the mechanism by which bacterial cell death occurs is not fully understood. In order to determine whether there is a correlation between quinolone-induced inhibition of early (i.e., 10 to 15 min) DNA synthesis and potency (MICs and MBCs), we measured the rate of DNA synthesis in(More)
