background recent evidences have revealed that in more than 65% of microbial infections, biofilms have critical roles. the ability of yeasts to form biofilms on surface of medical devices such as urine catheters is an important reason of the capability of these microorganisms to cause human disease. objectives the aim of this study was to isolate and identify yeasts on the surfaces of urine cat...

Secretion of hydrolytic enzymes is considered a virulence factor in Candida spp. Extracellular enzymatic activities in 29 clinical isolates of Candida tropicalis were analyzed by plate assays. C. tropicalis, similar to Candida albicans, showed elevated hemolytic and esterase activities. However, unlike C. albicans, low aspartyl protease and very low phospholipase activities were detected in C. ...

In this study, the resistance to antifungal drugs was investigated among 51 strains of Candida tropicalis isolated from clinical samples in the State of Ceará, Brazil. Antifungal resistance was a rare finding in our study and was restricted to three (5.9%) of the strains of Candida tropicalis. These exhibited resistance to both fluconazole and itraconazole.

OBJECTIVE To identify Candida species in asymptomatic subjects in Bobo-Dioulasso (Burkina Faso) by the matrix-assisted laser desorption ionization-time of flight mass spectrometry. METHODS A cross-sectional study was conducted from January to February 2013 in Bobo-Dioulasso to collect fecal and urine specimens from voluntary donors. Fungal strains were isolated on Sabouraud dextrose agar and ...

OBJECTIVE The aim of this study was to compare the prevalence of Candida spp. in diabetics and nondiabetics with and without denture stomatitis (DS). STUDY DESIGN Mycologic samples were taken from the dentures of 90 healthy subjects (control group [CG]), 80 denture stomatitis nondiabetics (DSND), and 40 denture stomatitis diabetics (DSD; well controlled type 2) for identification of Candida s...

From June to July 1998, two episodes of Candida tropicalis fungemia occurred in the Aristotle University neonatal intensive care unit (ICU). To investigate this uncommon event, a prospective study of fungal colonization and infection was conducted. From December 1998 to December 1999, surveillance cultures of the oral cavities and perinea of the 593 of the 781 neonates admitted to the neonatal ...

Candida tropicalis is a rare cause of acute cholangitis, predominantly seen in patients with underlying hematological malignancies. Here, we describe a case of acute cholangitis caused by mixed organisms (Candida tropicalis, Candida albicans, and Enterococcus durans) without a known risk factor.

A case of Candida tropicalis endophthalmitis following penetrating keratoplasty is presented. The donor was an alcoholic, who died of bronchopneumonia and pancreatitis. We presume the candida infection was transmitted by the donor because Candida tropicalis was cultured in life from the donor's throat swab and corresponding fungal elements were discovered post mortem in kidney sections of the d...

Susceptibilities to amphotericin B and fluconazole of 383 Candida species isolated from blood were determined. Candida albicans was the most common species (55.6%), followed by Candida parapsilosis (17.5%), Candida tropicalis (16.5%), Candida glabrata (5.2%), Candida guilliermondii (2.3%), and others (2.9%). All but three isolates, Candida ciferrii, C. tropicalis, and C. glabrata, one each, wer...

Fungi from the genus Candida are common members of the human microbiota; however, they are also important opportunistic pathogens in immunocompromised hosts. Several morphological transitions have been linked to the ability of these fungi to occupy the different ecological niches in the human body. The transcription factor Efg1 from the APSES family plays a central role in the transcription cir...
