We used an in vitro technique to investigate blood volumes required to detect bacteremia and fungemia with low concentrations of an organism. At 1 to 10 CFU/ml, Escherichia coli, Staphylococcus epidermidis, Staphylococcus aureus, Listeria monocytogenes, Candida albicans, and Candida parapsilosis isolates were detected in volumes as low as 0.5 ml. Detection of Streptococcus agalactiae and detect...

BACKGROUND Saccharomyces cerevisiae is well known in the baking and brewing industry and is also used as a probiotic in humans. However, it is a very uncommon cause of infection in humans. METHODS During the period of 15-30 April 2003, we found 3 patients with S. cerevisiae fungemia in an intensive care unit (ICU). An epidemiological study was performed, and the medical records for all patien...

Cryptococcus spp. other than Cryptococcus neoformans are generally considered nonpathogenic to humans. There are only 15 case reports of disease in humans caused by Cryptococcus laurentii infection. Underlying diseases and predisposing risk factors seem to play an important role in these cases. Our patient is the first case of an extremely low birth weight infant with C. laurentii fungemia repo...

The present article is an update of the literature on fungemia in onco-hematologic patients. A multidisciplinary group of Spanish physicians with an interest in this field selected the most important papers published lately. Papers from the fields of epidemiology, risk factors, pathogenesis, diagnosis, outcome, prevention and treatment are discussed. Important aspects of these studies include t...

We report the first case of fungemia due to Candida catenulata, a contaminant of dairy products. C. catenulata was isolated from three blood cultures of a patient with gastric cancer. The patient failed to respond to fluconazole but recovered after treatment was switched to amphotericin B. In vitro, C. catenulata was susceptible to amphotericin B and itraconazole and was also susceptible to flu...

BACKGROUND The present report describes the outcomes of a cohort of patients with Candida induced septic shock. METHODS Retrospective analysis of individuals who had at least one positive blood culture for Candida species ≥ 48 h after ICU admission. Data from patients that developed septic shock within 48 hr of the positive blood culture were compared to non-shock candidemic patients. Patient...

Purpose. The aim of this study is to determine the incidence and the predictors of ocular candidiasis among patient with Candida fungemia. Methods. We retrospectively reviewed the charts of all patients diagnosed with candidemia at the University of Kansas Medical Center during February 2000-March 2010. Data regarding patients' demographics, clinical characteristics, laboratory results, and oph...

We prospectively determined the antifungal susceptibility of yeast isolates causing fungemia using the Etest on direct blood samples (195 prospectively collected and 133 laboratory prepared). We compared the Etest direct (24 h of incubation) with CLSI M27-A3 and the standard Etest methodologies for fluconazole, voriconazole, posaconazole, isavuconazole, caspofungin, and amphotericin B. Strains ...

Antifungal treatment reduces the concentration of Histoplasma antigen in blood and urine, supporting a hypothesis that antigen clearance could be used to compare the activity of new agents for treating histoplasmosis. In separate trials in patients with AIDS, clinical response was similar with itraconazole (85%) and fluconazole (74%). Fungal blood cultures at week 4, however, were negative in a...

Gas-liquid chromatography (GLC) was used to study normal serum and serum from patients with septicemia caused by a variety of bacteria and by Candida albicans. The gas chromatograms of seven sera from six patients with septicemia due to C. albicans were found to be significantly and reproducibly different from those of normal sera. Chromatograms of serum from 19 bacteremic patients were indisti...
