1. Molecular epidemiology and antifungal susceptibilities of Aspergillus species isolated from patients with invasive aspergillosis
SUMMARY OBJECTIVE: The aim of this study was to evaluate the demographic data, molecular epidemiology, and in vitro antifungal susceptibility results of patients with Aspergillus isolated from various clinical specimens. METHODS: A total of 44 Aspergillus strains were studied. The definition of invasive aspergillosis in patients was made according to Europ

2. Disseminated fusariosis in a patient with bone marrow aplasia,
Abstract Fusariosis is a superficial or systemic infection, which occurs mainly in immunocompromised hosts, especially in patients with hematological neoplasia; 70%–75% of the cases present cutaneous manifestations. The disseminated form is rare and difficult to diagnose; even with specific treatment, the evolution is usually fatal. Currently, it is consid

3. Atividade in vitro do óleo essencial de Origanum vulgare L. em isolados clínicos de Aspergillus spp.
RESUMO Aspergillus fumigatus, A. flavus e A. niger são os mais importantes agentes etiológicos da aspergilose, relevante micose aviária, com tratamento ineficaz e altas taxas de mortalidade. Em vista da importância da aspergilose, da necessidade de prospectar novos fármacos e do potencial terapêutico do óleo essencial de Origanum vulgare L. (OEO), o o

4. Differential role of gpaB and sidA gene expressions in relation to virulence in Aspergillus species from patients with invasive aspergillosis
Abstract The virulence genes in invasive aspergillosis (IA) have not been analyzed adequately. The present study was designed to evaluate the expression of gpaB and sidA genes, which are important virulence genes in Aspergillus spp. from bronchoalveolar lavage (BAL) samples. Direct examination and culture on Czapek Agar and Sabouraud Dextrose Agar media were

5. Elastin increases biofilm and extracellular matrix production of Aspergillus fumigatus
Abstract Aspergillus fumigatus is an opportunistic saprobe fungus that accounts for 90% of cases of pulmonary aspergillosis in immunosuppressed patients and is known for its angiotropism. When it reaches the respiratory tract, A. fumigatus interacts with structural components and blood vessels of the lungs, such as elastin. To understand the effect of this s

6. Galactomannan use in clinical practice: providing free testing is not the full answer
ABSTRACT Introduction: Invasive aspergillosis is a condition associated with a high mortality rate mostly due to difficulties in performing an early diagnosis. In recent years, galactomannan detection has markedly improved the diagnosis of invasive aspergillosis, but very little is known on how physicians deal with this test in clinical practice. Methods:

7. In vitro antifungal susceptibility of clinical and environmental isolates of Aspergillus fumigatus and Aspergillus flavus in Brazil
ABSTRACT The in vitro susceptibility of 105 clinical and environmental strains of Aspergillus fumigatus and Aspergillus flavus to antifungal drugs, such as amphotericin B, azoles, and echinocandins was evaluated by the broth microdilution method proposed by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). Following the EUCAST-proposed

8. Complications of chronic necrotizing pulmonary aspergillosis: review of published case reports
ABSTRACT Chronic necrotizing pulmonary aspergillosis (CNPA), a form of chronic pulmonary aspergillosis (CPA), affects immunocompetent or mildly immunocompromised persons with underlying pulmonary disease. These conditions are associated with high morbidity and mortality and often require long-term antifungal treatment. The long-term prognosis for patients wi

9. Recombinant 60-kDa heat shock protein from Paracoccidioides brasiliensis: is it a good antigen for serological diagnosis of paracoccidioidomycosis?
Paracoccidioides brasiliensis and P. lutzii are fungi that cause paracoccidioidomycosis (PCM), the most prevalent systemic mycosis in South America. For serological diagnosis, although 43-kDa glycoprotein (gp43) is regarded as highly specific for PCM, the occurrence of false negative reactions in sera from patients infected with P. lutzii suggests that prepa

10. Standardization and validation of Dot-ELISA assay for Paracoccidioides brasiliensis antibody detection
Abstract Background Paracoccidioidomycosis (PCM) is a neglected systemic mycosis caused by a dimorphic fungus of the Paracoccidioides genus. The standard diagnosis is based on isolation of the fungi in culture, and by microscopic visualization of characteristic multiple budding yeast cells in biological samples. However, in some situations, access to the s

11. Invasive fungal infection in patients with hematologic disorders in a Brazilian tertiary care hospital
ABSTRACT INTRODUCTION: Invasive fungal infections (IFIs) are an important complication in immunocompromised individuals, particularly neutropenic patients with hematological malignancies. In this study, we aimed to verify the epidemiology and diagnosis of IFIs in patients with hematologic problems at a tertiary hospital in Goiânia-GO, Brazil. METHODS: D

12. The importance of risk factors for the prediction of patients with invasive pulmonary aspergillosis
Summary Objective: Invasive pulmonary aspergillosis (IPA) is a major challenge in the management of immunocompromised patients. Despite all the advances in diagnosis, it remains a problem. The purpose of our study was to investigate the risk factors associated with IPA seen in patients with hematological malignancies. Method: A total of 152 febrile neutrop
