1. Antifungal activity of selected plant extracts based on an ethnodirected study
ABSTRACT Plants have been reported as used by local populations to treat various infections for a long time, which has directed several pharmacological studies. The main aim of this work was to evaluate three plant selection criteria with better predictive power to detect extracts with antifungal action: (1) medicinal plants that are not used for indications

2. 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

3. The epidemiology of cryptococcosis and the characterization of Cryptococcus neoformans isolated in a Brazilian University Hospital
ABSTRACT Cryptococcosis, a systemic disease caused by the fungus Cryptococcus neoformans/ Cryptococcus gattii is more severe in immunocompromised individuals. This study aimed to analyze the epidemiology of the disease, the molecular characteristics and the antifungal susceptibility of C. neoformans isolated from patients treated in a Brazilian university ho

4. 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

5. Antifungal susceptibility of clinical and environmental Cryptococcus neoformans and Cryptococcus gattii isolates in Jabalpur, a city of Madhya Pradesh in Central India
In this study, we present antifungal susceptibility data of clinical and environmental isolates of Central Indian Cryptococcus neoformans (Serotype A, n = 8 and n = 50 respectively) and Cryptococcus gattii (Serotype B, n = 01 and n = 04 respectively). Susceptibilities to fluconazole, itraconazole and ketoconazole were determined by using NCCLS broth micro-di

6. Ocorrência e caracterização da criptococose em cães e gatos em Mato Grosso
A criptococose é uma infecção que afeta humanos e animais sendo a etiologia atribuída às espécies Cryptococcus neoformans variedade neoformans, C. neoformans var. grubii e C. gattii. A doença é comum em cães e gatos, causando infecções respiratórias, neurológicas, cutâneas e oculares. Com o objetivo de entender melhor a epidemiologia da criptoc

7. Clinical and microbiological features of cryptococcal meningitis
Introduction In this study, the clinical features, underlying diseases and clinical outcomes of patients with cryptococcosis were investigated. In addition, a molecular analysis of the Cryptococcus neoformans species complex isolated from these patients was performed. Methods A prospective study of 62 cases of patients with cryptococcal infection was cond

8. Comparison of primers for RAPD-PCR from environmental isolates of Cryptococcus neoformans, Cryptococcus albidus and Cryptococcus laurentii complex
Various organisms have been characterized by molecular methods, including fungi of the genus Cryptococcus. The purposes of this study were: to determine the discriminatory potential of the RAPD (Random Amplified Polymorphic DNA) primers, the pattern of similarity of the Cryptococcus species, and discuss their useful application in epidemiological studies. We

9. Cryptococcus neoformans var. grubii - Pathogenicity of environmental isolates correlated to virulence factors, susceptibility to fluconazole and molecular profile
The pathogenicity of Cryptococcus neoformans is heterogeneous and is associated with the expression of virulence factors. This study aimed to correlate the pathogenicity of C. neoformans var. grubii in BALB/c mice with in vitro virulence factors, fluconazole minimal inhibitory concentrations (MICs) and molecular profiles, before and after animal passage.

10. Antifungal activity of the naphthoquinone beta-lapachone against disseminated infection with Cryptococcus neoformans var. neoformans in dexamethasone-immunosuppressed Swiss mice
The in vivo antifungal activity of the naphthoquinone beta-lapachone against disseminated infection by Cryptococcus neoformans was investigated. Swiss mice were immunosuppressed daily with dexamethasone (0.5 mg per mouse) intraperitoneally for 3 days, the procedure was repeated 4 days later, and the animals were then challenged intravenously with C. neoforma

11. Cryptococcus neoformans var. : neoformans isolado do solo
Na tentativa de identificar a possível fonte de infecção, inquiriu-se, na história epidemiológica de 42 pacientes portadores de criptococose, o contato com pombos. Informações compatíveis com nicho ecológico do Cryptococcus neoformans foram positivas em 16. Foram colhidas 59 amostras de solo contendo fezes de pombos, penas e material orgânico. O C.
