Susceptibility profiles of medically important fungi in less-developed countries remain uncharacterized. We measured the MICs of amphotericin B, 5-flucytosine, fluconazole, itraconazole, and ketoconazole for Cryptococcus neoformans clinical isolates from Thailand, Malawi, and the United States and found no evidence of resistance or MIC profile differences… (More)
A real-time PCR assay that uses two fluorescence resonance energy transfer probe sets and targets the tuf gene of staphylococci is described here. One probe set detects the Staphylococcus genus, whereas the other probe set is specific for Staphylococcus aureus. One hundred thirty-eight cultured isolates, which contained 41 isolates of staphylococci… (More)
Impact of methicillin resistance on the outcome of patients with bacteremia caused by Staphylococcus au-reus. SIR—Enterohemorrhagic strains of Escherichia coli (EHEC), which cause disease, at least in part, by producing shiga-toxins, have become a serious public health concern . Although he-molytic uremic syndrome most commonly follows hemorrhagic… (More)
The prompt and accurate identification of bacterial pathogens is fundamental to patient health and outcome. Recent advances in matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) have revolutionized bacterial identification in the clinical laboratory, but uniform incorporation of this technology in the U.S. market has… (More)
Spectra MRSA agar (Remel, Lenexa, KS), a novel chromogenic medium originally developed to detect methicillin-resistant Staphylococcus aureus (MRSA) from nasal swabs, was evaluated in this multicenter study for the detection of MRSA from positive blood cultures exhibiting Gram-positive cocci upon initial Gram staining.
The increasing prevalence of vancomycin-resistant enterococcal (VRE) infections has necessitated a search for drugs that are effective in treating these infections, and a need to determine whether currently available antimicrobials are effective. 75 consecutive clinical isolates of vancomycin-resistant Enterococcus faecium (VRE faecium) (40 blood and 35… (More)
BACKGROUND A colorimetric sensor array (CSA) has been demonstrated to rapidly detect and identify bacteria growing in blood cultures by obtaining a species-specific "fingerprint" of the volatile organic compounds (VOCs) produced during growth. This capability has been demonstrated in prokaryotes, but has not been reported for eukaryotic cells growing in… (More)
