1. An exceptional case report of disseminated cryptococcosis in a hitherto immunocompetent patient
ABSTRACT Cryptococcosis is an opportunistic fungal infection causes significant disease predominantly in immunocompromised patients. Here we present an excepcional case of disseminated cryptococcosis with pulmonary and cerebral involvement in an immunocompetent patient with no apparent predisposing factors at the time of hospital admission. We described a ca

2. Epidemiological and TNFα polymorphism evaluation in patients with cryptococcal meningitis treated at a referral hospital in North Brazil
Abstract INTRODUCTION: The present study evaluated the epidemiology of cryptococcal meningitis and TNFα gene polymorphisms in patients at a reference hospital in northern Brazil. METHODS: Samples from 25 patients infected with Cryptococcus spp. were collected to confirm the infection and to analyze the TNFα gene polymorphisms. RESULTS: Cryptococcus ne

3. Fluconazole levels in serum and cerebrospinal fluid according to daily dosage in patients with cryptococcosis and other fungal infections
ABSTRACT Fluconazole is extensively used for the treatment of candidiasis and cryptococcosis. Among other factors, successful treatment is related to appropriate fluconazole levels in blood and cerebrospinal fluid. In the present study, fluconazole levels were determined in 15 patients, 14 of whom had AIDS and 13 had neurocryptococcosis. The only selection c

4. Cryptococcus neoformans and C. gattii isolates from both HIV-infected and uninfected patients: antifungal susceptibility and outcome of cryptococcal disease
ABSTRACT One of the factors causing treatment failure in cryptococcosis is the resistance of Cryptococcus spp. to antifungal drugs, which has motivated the susceptibility assessment of isolates from patients with cryptococcosis, different clinical conditions and infections outcomes. Clinical isolates of Cryptococcus spp. from three different groups of patien

5. Use of fluorescent oligonucleotide probes for differentiation between Paracoccidioides brasiliensis and Paracoccidioides lutzii in yeast and mycelial phase
BACKGROUND Fluorescence in situ hybridisation (FISH) associated with Tyramide Signal Amplification (TSA) using oligonucleotides labeled with non-radioactive fluorophores is a promising technique for detection and differentiation of fungal species in environmental or clinical samples, being suitable for microorganisms which are difficult or even impossible

6. Azole resistance in Candida spp. isolated from Catú Lake, Ceará, Brazil: an efflux-pump-mediated mechanism
Abstract Since, there is no study reporting the mechanism of azole resistance among yeasts isolated from aquatic environments; the present study aims to investigate the occurrence of antifungal resistance among yeasts isolated from an aquatic environment, and assess the efflux-pump activity of the azole-resistant strains to better understand the mechanism of

7. Cryptococcus spp. em excretas de Columba livia (pombos domésticos) provenientes de um hospital universitário no Sul do Brasil
RESUMO A criptococose é uma micose primariamente pulmonar, sendo adquirida por meio de inalação de propágulos fúngicos infectantes encontrados no ambiente. Um dos principais agentes etiológicos da criptococose é a espécie Cryptococcus neoformans , que apresenta distribuição mundial. O objetivo desse trabalho foi pesquisar a ocorrência de Cryptococ

8. Caracterização bioquímica e molecular de Cryptococcus spp. isolados de excretas ambientais de pombos (Columba livia domestica)
Os pombos possuem uma rica diversidade de microrganismo, entre eles fungos sapróbios, como do gênero Cryptococcus, que podem atuar como agentes patogênicos para o homem e animais. Objetivou-se o isolamento, a caracterização bioquímica e a molecular de amostras de Cryptococcus spp. de excretas ambientas de pombos. Foram colhidas 100 amostras ambientais

9. Simvastatin inhibits planktonic cells and biofilms ofCandida and Cryptococcusspecies
ABSTRACTThe antifungal activity of some statins against different fungal species has been reported. Thus, at the first moment, the in vitro antifungal activity of simvastatin, atorvastatin and pravastatin was tested againstCandida spp. and Cryptococcus spp. Then, in a second approach, considering that the best results were obtained for simvastatin, this drug

10. Fungos isolados de excretas de aves silvestres em centro de reabilitação em Pelotas, RS, Brasil
A identificação das espécies de fungos pertencentes à microbiota saudável em animais é pré-condição para o reconhecimento dos processos patológicos causados por esses. O objetivo deste estudo foi investigar a presença de fungos potencialmente patogênicos nas fezes de aves selvagens coletadas em Centros de Triagem. Foram coletadas amostras de feze

11. Puerperal brain cryptococcoma in an HIV-negative woman successfully treated with fluconazole: a case report
Cryptococcus spp. cerebral abscesses are uncommon in immunocompetent subjects. The recommended induction treatment is the administration of amphotericin B plus flucytosine combined with resection for lesions ≥3cm. In this paper, we describe an HIV-negative woman diagnosed with a large cryptococcoma in the immediate postpartum period. The lesion was not res

12. Características histomorfológicas e histoquímicas determinantes no diagnóstico da criptococose em animais de companhia
Sete casos de criptococose (seis gatos e um cão) foram estudados para estabelecer as características histomorfológicas e histoquímicas determinantes no diagnóstico histopatológico dessa condição. Os dados complementares relacionados à epidemiologia, aos aspectos clínicos, à localização das lesões e às alterações macroscópicas foram obtidos
