Tetrazolium medium as an aid in the routine diagnosis of Candida 1
نویسنده
چکیده
SYNOPSIS The tetrazolium medium described is easily prepared and serves as a rapid, relatively accurate and simple means of differentiating Candida species, particularly C. albicans, from other yeasts. Culture on this medium does not replace other techniques used for yeast identification. No one test alone will suffice and final identification must rest on an overall pattern of characteristics. In the screening of 1,822 yeast isolates in this laboratory, culture on this medium has proved a valuable adjunct to other recognized techniques, and is now in regular use.

Routine identification of yeasts with the aid of molybdate-agar medium.
A large number of yeasts, including a variety of species other than Candida albicans, were isolated from clinical specimens. C. tropicalis and Torulopsis glabrata were each found one-third as frequently as C. albicans. A schema is presented which made possible, by simple procedures, the identification of the great majority of the isolated yeasts. Preliminary isolation and differentiation was ai...
متن کاملIdentification of Candida Species Isolated from Hospitalized Patients with Candiduria
Background and objectives: The incidence of candiduria caused by Candida spp. has increased in recent years, particularly in hospitalized patients. Candiduria is most commonly caused by Candida albicans; however, an increase in the prevalence of non-albicans species has been observed during last decades. This study aimed at molecular identification of Candida species isolated from candiduria in...
متن کاملCandida albicans susceptibility to lactoperoxidase-generated hypoiodite
In vivo, lactoperoxidase produces hypothiocyanite (OSCN(-)) from thiocyanate (SCN(-)) in the presence of hydrogen peroxide (H2O2); in vitro, iodide (I(-)) can be oxidized into hypoiodite (OI(-)) by this enzyme. The aim of this study was to compare in vitro the anti-Candida effect of iodide versus thiocyanate used as lactoperoxidase substrate to prevent Candida biofilms development. Candida albi...

Introduction: Recurrent Vulvovaginal Candidiasis (RVVC), which is mostly caused by Candida albicans (C. albicans), is the second common cause of genital tract infection in females. The purpose of this research was to identify Candida isolates from RVVC, identify predisposing factors and determine antifungal effect of fluconazole against Candida strains isolated from the patients. Methods: In...

Candida albicans has the ability to change between yeast and hyphal cells and is known to be a virulence property. Efg1gene of C.albicans is as a main transcription factor that plays pivotal roles in biofilm formation The aim of the current study is to investigate the presence of Efg1 gene in Candida albicans isolates from women with vaginal candidiasis and its impact on biofilm formation.We us...
