25. 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

26. Synergistic antifungal activity of the lipophilic fraction of Hypericum carinatum and fluconazole
ABSTRACT Hypericum species, Hypericaceae, are recognized as a source of therapeutical agents. Purified fractions and isolated compounds have been shown antimicrobial activity. As the indiscriminate use of antifungals and the increase of infections caused by emerging species are leading to the search of new alternative treatments, the aim of this study was to

27. Improvement of Solubility and Antifungal Activity of a New Aminothiophene Derivative by Complexation with 2-Hydroxypropyl-β-cyclodextrin
This study aimed to prepare a complex of 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) and 6CN10, a poorly water soluble 2-aminothiophene derivative with antifungal properties, by freeze-drying technique. The complex was characterized by thermal analysis, infrared/Raman spectroscopy, X-ray diffraction and scanning electron microscopy. In addition, we used the d

29. Disseminated cryptococcosis manifested as a single tumor in an immunocompetent patient, similar to the cutaneous primary forms
Abstract Cryptococcosis is a fungal infection caused by Cryptococcus neoformans that tends to affect immunocompromised individuals. The fungi are mostly acquired by inhalation, which leads to an initial pulmonary infection. Later, other organs - such as the central nervous system and the skin - can be affected by hematogenous spread. In addition, cutaneous c

30. ANTIFUNGAL SUSCEPTIBILITY TESTING AND GENOTYPING CHARACTERIZATION OF Cryptococcus neoformans AND gattii ISOLATES FROM HIV-INFECTED PATIENTS OF RIBEIRÃO PRETO, SÃO PAULO, BRAZIL
SUMMARY Cryptococcosis is a leading invasive fungal infection in immunocompromised patients. Considering the high prevalence and severity of these infections in immunocompromised patients attended at HC-FMRP-USP, the present research aimed to characterize the clinical isolates of Cryptococcus strains by biochemical and molecular methods and evaluate antifung

31. Antifungal efficacy of amphotericin B encapsulated fibrin microsphere for treating Cryptococcus neoformans infection in Swiss albino mice
Abstract A natural and biocompatible fibrin microsphere is one of the most promising dual delivery vehicle as compared to other traditionally designed delivery modalities. It represents sustained delivery of encapsulated drug and is easily biodegradable in the blood circulation. In the present study, we evaluated the systemic augmentation of the antifungal a

32. Quercetina e rutina: potenciais agentes para terapia antifúngica
Resumo A anfotericina B é uma substância fungicida e é o tratamento de escolha para a maioria das infecções fúngicas sistêmicas que afetam os pacientes imunocomprometidos, como a criptococose. No entanto, as severas reações adversas têm limitado a utilização desta droga. O objetivo deste estudo foi avaliar o efeito antifúngico e o potencial efei

33. 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

34. 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

35. Cryptococcus laurentii fungaemia in a cervical cancer patient
ABSTRACT Infections caused by emerging Cryptococcus non-neoformans species are being reported with increasingly frequency. Here, we present a case of fungaemia byCryptococcus laurentii in a woman receiving aggressive immunosuppressive therapy for cervical neoplasia. Three venous blood samples were aseptically collected on consecutive days and C. laurentiiwas

36. Validation and clinical application of a molecular method for the identification of Cryptococcus neoformans/Cryptococcus gattii complex DNA in human clinical specimens
ABSTRACT The diagnosis of cryptococcosis is usually performed based on cultures of tissue or body fluids and isolation of the fungus, but this method may require several days. Direct microscopic examination, although rapid, is relatively insensitive. Biochemical and immunodiagnostic rapid tests are also used. However, all of these methods have limitations th
