1. Candida parapsilosis complex water isolates from a haemodialysis unit: biofilm production and in vitro evaluation of the use of clinical antifungals
Candida parapsilosis, currently divided into three distinct species, proliferates in glucose-rich solutions and has been associated with infections resulting from the use of medical devices made of plastic, an environment common in dialysis centres. The aims of this study were (i) to screen for Candida orthopsilosis and Candida metapsilosis (100 environmenta

2. Comparison of microbiological assay and HPLC-UV for determination of fluconazole in capsules
Este trabalho visou ao desenvolvimento e validação de um método microbiológico por difusão em ágar para quantificação de fluconazol em cápsulas utilizando o isolado Candida albicans ATCC 18804 como reagente biológico. O método foi validado e foi verificada linearidade (r²=0,9995), precisão (D.P.R. = 4.0% para precisão intra-dia e 4,5% para prec

3. Fator hemolítico em Candida tropicalis
Embora o fator hemolítico seja reconhecido como um possível fator que contribui para a patogenicidade de espécies de Candida, a atividade hemolítica de Candida tropicalis e sua expressão ainda permanecem pouco conhecidas. Neste estudo foi analisada a secreção do fator hemolítico em 16 isolados de C. tropicalis provenientes de diversos sítios de infe

4. Ação protetora de extrato de sementes de Artocarpus integrifolia L. contra infecção por Candida albicans através do aumento das funções de fagócitos
Este trabalho pesquisou os principais efeitos de extrato de sementes de Artocarpus integrifolia (EJ), na fagocitose e morte de Candida albicans, na produção de TNF-a e envolvimento com a sobrevivência dos animais a um inóculo letal do fungo. Os macrófagos de animais pré-tratados com EJ por 72 h foram co-incubados 1:5 leveduras de C. albicans (CR15) por

5. DESENVOLVIMENTO E VALIDAÇÃO DE METODOLOGIAS ANALÍTICAS PARA DETERMINAÇÃO DO ITRACONAZOL MATÉRIA-PRIMA E CÁPSULAS / DEVELOPMENT AND VALIDATION OF ANALITICAL METHODS FOR DETERMINING ITRACONAZOLE RAW MATERIALS AND CAPSULES
O itraconazol é um antifúngico triazólico de amplo espectro de ação pertencente à classe dos azóis, indicado no tratamento de diferentes tipos de infecções micóticas sistêmicas e superficiais. Seu mecanismo de ação baseia-se na capacidade de inibição da síntese do ergosterol que é um componente de vital importância para a membrana das célu

6. Efficacy of three denture brushes on biofilm removal from complete dentures
The aim of this study was to compare the efficacy of three denture brushes (Bitufo-B; Medic Denture-MD; Colgate-C) on biofilm removal from upper and lower dentures using a specific dentifrice (Corega Brite). The correlation between biofilm levels on the internal and external surfaces of the upper and lower dentures was also evaluated. A microbiological assay

7. Kinetics of Phagocytosis and Intracellular Killing of Candida albicans by Human Granulocytes and Monocytes
The study of the phagocytosis and intracellular killing of Candida albicans by granulocytes and monocytes has been hampered by the budding and pseudomycelium formation of this yeast during a relatively short incubation period at 37°C and by the similar density of candida cells and phagocytes, which makes differential centrifugation impossible. In the presen

8. Diagnostic value of the enzyme-linked immunosorbent assay for detection of Candida albicans cytoplasmic antigen in sera of cancer patients.
To diagnose systemic candidiasis we developed an enzyme-linked immunosorbent assay (ELISA) for the quantitation of Candida albicans cytoplasmic antigen in sera of cancer patients. The antigen concentration was evaluated in 59 patients divided into several groups according to clinical, histological, and microbiological findings as well as antimicrobial treatm

9. Bacteraemia due to recurrent reinfection with Staphylococcus epidermidis associated with defective opsonisation and procidin function in serum.
AIMS--To differentiate between reinfection and relapsing infection with Staphylococcus epidermidis in a middle-aged woman with defective opsonisation and procidin function in serum. METHODS--Microbiological typing was done by biotyping, phage typing, and polyacrylamide gel electrophoresis of radiolabelled bacterial proteins (radioPAGE method). Polymorphonucl

10. Comparison of High-Performance Liquid Chromatographic and Microbiological Methods for Determination of Voriconazole Levels in Plasma
A new selective high-performance liquid chromatography (HPLC) method with UV detection for the determination of the investigational triazole voriconazole in human plasma by using acetonitrile precipitation followed by reverse-phase HPLC on a C18 column was compared with a simple agar well diffusion bioassay method with Candida kefyr ATCC 46764 as the assay o
