Invasive fungal infections (IFIs) are serious and often life-threatening complications in patients with haematological malignancies. Early diagnosis and the initiation of efficacious antifungal treatments could affect the prognosis of these patients. The detection of (1-3)-β-D-Glucan (BDG) could be a promising non-culture-based, noninvasive tool for IFI(More)
Glutaraldehyde-inactivated cells and cell-wall fractions of Candida albicans were studied for their capacity to induce or inhibit the in-vitro proliferation of human peripheral blood mononuclear cells (PBMC), as measured by 3H-thymidine incorporation. Both the intact cells (CA) and a phosphorylated gluco-mannan-protein complex of the cell wall (GMP), in(More)
The expression of a strongly immunomodulatory mannoprotein complex (GMP) in the different forms of growth of the human commensal and opportunistic pathogen Candida albicans was studied using a monoclonal antibody (mAb AF1) directed against an oligosaccharide epitope of GMP. Immunofluorescence revealed that the surface of the yeast cells was highly reactive(More)
Antifungal agents have greatly contributed to the improvement of public health. Nevertheless, antifungal resistant pathogens have increased during the past decade, becoming a serious concern. Candida albicans has been the most extensively studied pathogen in antifungal resistance because of their morbidity and mortality associated with infections in(More)
The cytokine responses exerted by virus-primed spleen T cells upon in vitro restimulation were studied. Spleen cells obtained from mice injected intraperitoneally with A/PR8 (H1N1) influenza virus (PR8) were restimulated in vitro with UV-inactivated PR8 virus. The percentage of both CD4+ and CD8+ T cells producing IL2, IL4, or IFN-gamma was assayed at the(More)
Yeast or mycelial cultures of Candida albicans released comparable amounts of Concanavalin A-reactive mannoprotein material after 24-h of growth, and in both cases this material showed a qualitatively similar SDS-PAGE pattern, with predominantly polydisperse constituents of high molecular mass. The two secretion mixtures also showed similar reactivity by(More)
OBJECTIVE Candida albicans biofilm is frequently found on artificial surfaces and the infections related to biofilm are difficult to eliminate, as they require the removal of artificial devices and treatment with antifungal drugs. Nowadays, fungal growth in biofilms is difficult to eradicate with conventional antifungal drugs such as fluconazole. Among(More)
A new method of orotracheal intubation in mice is described. After intraperitoneal induction of anaesthesia, 36 male animals, belonging to common laboratory strains, have been intubated with the aid of a straight, small bore arthroscope, connected to a video-camera. After the insertion of a guide wire of appropriate size across the vocal cords, a(More)
We have studied the patterns of interleukin-2 (IL-2), IL-4 and interferon-gamma (IFN-gamma) co-expression displayed by individual splenic CD4+ and CD8+ T cells in response to influenza virus immunization. Unseparated spleen cells obtained from mice intraperitoneally (i.p.) injected with A/PR8 (H1N1) influenza virus (PR8) were cultured for 24 hr in the(More)
We investigated the efficacy of fluconazole on experimental disseminated candidiasis in mice immunocompromised by chronic morphine treatment. CD1 mice were severely immunosuppressed by repeated morphine administrations, i.e., subcutaneous (s.c.) injections of 75 mg/kg/day, 3 days before and 5 days after a systemic Candida albicans infection induced by(More)
