OBJECTIVES The aim of this study was to assess the dose-response of isavuconazole, voriconazole and fluconazole in disseminated Candida tropicalis and Candida krusei infections. METHODS Mice were immunosuppressed using either one dose [temporarily neutropenic (TN)] or two doses [persistently neutropenic (PN)] of cyclophosphamide. Treatment was started 5 h after infection with oral isavuconazo...

Twelve women with vaginal Candida krusei infection were evaluated. In vitro antifungal susceptibility testing and molecular typing were performed. Patients infected with C. krusei frequently had refractory vulvovaginal signs and symptoms that were otherwise indistinguishable from vaginitis due to other yeasts. Patients were 32-63 years old and had previously received multiple courses of antimyc...

There is only scanty data on the effects of specific antibody, with or without complement, on Candida albicans or Candida krusei in cell-free systems in vitro, although previously published work has shown that specific antibody mediates anti- Candida immunity in vivo by inhibition of adherence to host cells or surfaces and by the promotion of phagocytosis and intra-phagocytic killing. The MTT (...

Thirty-eight Zimbabwean medicinal plant extracts were investigated for in vitro antifungal activity against Candida albicans and Candida krusei. These plants are used for the traditional treatment of various ailments, including fungal infections. The ethanol extracts were tested for antifungal activity using the agar disc diffusion method. The minimum inhibition concentrations (MICs) were deter...

BACKGROUND Candida krusei infections are associated with high mortality. In order to explore ways to prevent these infections, we investigated potential routes for nosocomial spread and possible clonality of C. krusei in a haematological unit which had experienced an unusually high incidence of cases. METHODS We searched for C. krusei contamination of the hospital environment and determined t...

Here, we report a case of disseminated Candida krusei infection in a patient who presented with arthritis. The infection was successfully treated with voriconazole after amphotericin B deoxycholate therapy had failed.

Background and Purpose: Candida species constitute an important group of opportunistic fungi, which cause various clinical diseases. Considering the resistance of some Candida species to conventional antifungal agents, treatment of such cases may be challenging and complicated. The purpose of this study was to evaluate and compare the antifungal activities of Euphorbia macroclada latex and fluc...

Most Candida infections are related to microbial biofilms often formed by the association of different species. The objective of this study was to evaluate the interactions between Candida albicans and non-albicans species in biofilms formed in vitro. The non-albicans species studied were:Candida tropicalis, Candida glabrata and Candida krusei. Single and mixed biofilms (formed by clinical isol...

We investigated the correlation between in vitro susceptibility to fluconazole and clinical response in severely ill patients with oropharyngeal candidiasis treated with fluconazole. The study included 48 adult patients, of whom 23 were neutropenic (absolute neutrophil count, < 500/mm3). Forty-eight isolates (20 Candida albicans, 12 Candida krusei, 10 Candida kefyr, 3 Torulopsis glabrata, and 3...

In this study, nanoparticles (NPs) of poly(lactic-co-glycolic acid) (PLGA) loaded with fluconazole (FLZ) and FLZ-NPs coated with the cationic polymer polyethylenimine (PEI) (FLZ-NP-PEI) were synthetized in order to improve antimycotic activity against four strains of Candida spp. of clinical relevance. FLZ-NPs and FLZ-NP-PEI were synthesized by double emulsion solvent-diffusion (DES-D) and char...
