A case of sporotrichosis caused by different Sporothrix brasiliensis strains: mycological, molecular, and virulence analyses

Mem. Inst. Oswaldo Cruz; 114 (), 2019
BACKGROUND Sporotrichosis is a subcutaneous mycosis caused by dimorphic pathogenic fungi belonging to the Sporothrix genus. Pathogenic Sporothrix species typically produce melanin, which is known to be a virulence factor. OBJECTIVES The aim of this study was to perform phenotypic, genotypic, and virule...

Antifungal activity of nanoemulsions encapsulating oregano (Origanum vulgare) essential oil: in vitro study and application in Minas Padrão cheese

Braz. j. microbiol; 49 (4), 2018
ABSTRACT The objective of this study was to evaluate the antifungal activity of nanoemulsions encapsulating essential oil of oregano (Origanum vulgare), both in vitro and after application on Minas Padrão cheese. Nanodispersions were obtained by the phase inversion temperature method. Cladosporium sp., ...

Identification of Fungal Pathogens in Otomycosis and Their Drug Sensitivity: Our Experience

Abstract Introduction Otomycosis is a common problem in otolaryngology practice. However, we usually encounter some difficulties in its treatment because many patients show resistance to antifungal agents, and present high recurrence rate. Objectives To determine the fungal pathogens that cause otomyco...

Identification and susceptibility of clinical isolates of Candida spp. to killer toxins

Braz. j. biol; 78 (4), 2018
Abstract Although invasive infections and mortality caused by Candida species are increasing among compromised patients, resistance to common antifungal agents is also an increasing problem. We analyzed 60 yeasts isolated from patients with invasive candidiasis using a PCR/RFLP strategy based on the inte...

Black and white teas as potential agents to combine with amphotericin B and protect red blood cells from amphotericin B-mediated toxicity

Braz. j. biol; 78 (4), 2018
Abstract Amphotericin B is a fungicidal substance that is treatment of choice for most systemic fungal infections affecting immunocompromised patients. However, severe side effects have limited the utility of this drug. The aim of this study was to evaluate the antifungal effect of the combination of amp...

Distribution of clinical isolates of Candida spp. and antifungal susceptibility of high biofilm-forming Candida isolates

Abstract INTRODUCTION: The increase in the incidence of fungal infections, especially those caused by Candida albicans and other Candida species, necessitates the understanding and treatment of Candida-associated infections. In this study, we aimed to investigate the identification, distribution, and b...

Interactions between Terpinen-4-ol and Nystatin on biofilm of Candida albicans and Candida tropicalis

Braz. dent. j; 29 (4), 2018
Abstract The aim of this study was to evaluate the antifungal activity of Terpinen-4-ol associated with nystatin, on single and mixed species biofilms formed by Candida albicans and Candida tropicalis, as well as the effect of terpinen-4-ol on adhesion in oral cells and the enzymatic activity. The minimu...

In vitro antifungal susceptibility of Candida speciesisolated from diabetic patients

Abstract INTRODUCTION This study aims to evaluate the antifungal susceptibility of different species of Candida isolated from diabetic patients against eight antifungal agents. METHODS Susceptibility testing of 111 clinical isolates of Candida species was performed against 8 antifungals using the M27...

Clinical and laboratorial features of oral candidiasis in HIV-positive patients

Abstract INTRODUCTION We describe the clinical and laboratorial features of oral candidiasis in 66 HIV-positive patients. METHODS: Polymerase chain reaction-based techniques were performed for differentiation of Candida spp. isolated from patients at a public teaching hospital in Midwest Brazil. RESU...
