BACKGROUND Cryptococcosis is a generally systemic and potentially lethal fungal infection. Although HIV infection is a predisposing condition, especially if the CD4+ lymphocyte count is less than 100cells/mm3, other forms of immunosuppression may be associated with this opportunistic fungal condition, such as prolonged steroid therapy or solid organ transplantation. Pulmonary presentation must be included

BACKGROUND In the last three decades the species of Candida have been of great interest due to the high mortality rates that they cause in immunocompromised and hospitalized patients. These species are opportunistic pathogens and they have inhabited other environments long before colonizing human cells. Among these environments we find wastewater from mines, and water from aquifers and soils that contain

Lymphatic-cutaneous is the most common clinical manifestation. CASE REPORT The present case describes the development of an epidermoid carcinoma as a late complication on a long evolution sporotrichosis scar. During a period of 50 years, the patient had lesions

BACKGROUND Sporotrichosis is a fungal infection caused by the Sporothrix schenckii complex. In order to colonize the host, the pathogen must neutralize the reactive oxygen species produced by the phagocytic cells during the respiratory burst. Little is known about these mechanisms in S. schenckii. AIMS To identify the proteins differentially expressed after the exposure of S. schenckiisensu stricto

BACKGROUND The incidence of systemic infections by Saccharomyces cerevisiae has increased in recent years, especially among immunocompromised patients. Amphotericin B, voriconazole or echinocandins have been used with favorable outcome against systemic infections by this fungus.

BACKGROUND The enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (Hmgr) catalyzes the synthesis of mevalonate, a key compound for the synthesis of cholesterol in humans and ergosterol in fungi. Since the Hmgr enzymes of Saccharomyces cerevisiae, Schizosaccharomyces pombe and Candida glabrata are similar to the Hmgr enzymes of mammals, fungal Hmgr enzymes have been proposed as a model for studying

BACKGROUND Candida parapsilosis may acquire resistance to echinocandins, a fact that prompts the search for new therapeutic options. AIMS The present study aimed to evaluate the in vitro activity of antifungal agents, alone and in combination, against four groups of C. parapsilosis strains: (1) echinocandin-susceptible (ES) clinical isolates (MIC ≤ 2μg/ml), (2) anidulafungin-resistant strains (MIC

CASE REPORT Four different moulds were isolated

Critically ill patients without severe immunosuppression make up a population in which invasive aspergillosis (IA) has been identified as an emergent pathology. Chronic treatment with corticosteroids, chronic obstructive pulmonary disease, and liver cirrhosis are repeatedly identified risk factors. However, due to the non-specificity of the symptoms and signs in the critical patient, and the relative
