Abstract

BackgroundBiofilm formation by Candida species is an influential virulence factor in candidemia pathogenesis. We investigated the relationship between biofilm formation of Candida tropicalis isolates with the clinical characteristics and mortality outcomes in patients with candidemia.Materials and methodsThirty-nine C. tropicalis isolates were recovered from patients with candidemia admitted to two university hospitals in Tehran, Iran. Biofilm mass and metabolic activity of C. tropicalis biofilms were assessed in vitro with two colorimetric methods. The sessile minimum inhibitory concentrations (SMICs) were evaluated in vitro by treating preformed biofilms with diluted concentrations of azoles according to CLSI-M27 A3/S4 protocol, followed

Abstract

BackgroundVirulence factors intensify the pathogenicity of Candida species in candidemia. Limited knowledge exists regarding the azole-resistant mechanism and virulence factors of Candida tropicalis. Consequently, we aimed to evaluate the virulence factors and the molecular mechanisms of azole resistance among C. tropicalis isolated from bloodstream infection.

Abstract

ObjectiveTrichophyton verrucosum is a slow growing dermatophyte responsible for a number of skin diseases such as ringworm, and is characterized by patches of hair loss and thick crusts on the host skin in domestic animals. In this study, we examined the immunomodulatory effects of crude extract of Trichophyton verrucosum (TV)cytoplasm in a mouse model.MethodsThe TV variate was cultured on Sabouraud dextrose agar and the mycelium was grinded by mechanical force. The purified protein was obtained from crude extract of the fungus, and protein concentration was measured by BradFord assay. Six to eight week-female BALB/c mice were divided into three groups: test group, receiving cytoplasmic crude extract plus defibrinated sheep blood; control g

Abstract

Secreted aspartyl proteinases (Saps), are gene products that have been shown to directly contribute to Candida albicans pathogenicity. Despite the clear difficulties of systemic C. albicans infections control, Antimicrobial peptides (AMPs) are regarded as one of the most promising alternatives in this regard. Recently, drug-loaded electrospun nanofibers have attracted a great deal of attention. In this study we have established the nanofibrous scaffold of new synthetic peptide/Poly (Vinyl Alcohol)/Poly l-Lactic Acid on expression of Secretory aspartyl proteinases 4 to 6 genes of C. albicans in comparison with free peptide. We designed new synthetic Antimicrobial peptide (AMPs) used bioinformatics tools to predict structure and stabilities.

Abstract

ObjectiveThe effect of candidemia on immunologic parameters in breast tumor bearing patients is not well studied. Here, we hypothesised that candidemia in the tumor background may change the outcome of immunologic parameters and tumor condition.MethodMice were divided into four groups, including normal, tumor, Candida infected (only Candidiasis) and tumor/Candidiasis groups. Tumor changes were recorded daily after tumor transplantation and induction of candidemia. Splenocytes of mice were harvested, cultured, and stimulated with PHA; afterwards, IL-4, IL-10, IFN-γ, TNF-α and TGF-β cytokines were assessed using ELISA kits. We also evaluated the population of CD4+CD25+Foxp3+ regulatory T cells in the tumor infiltrated and splenocytes.Resul

Abstract

An experiment was conducted to study the effect of savory (Satureja khuzistanica) extract on the performance, organ weight, immune response and hepatic enzymes in broiler chickens. 320 day-old Ross chickens were assigned to four distinct treatments in a completely randomized design. Each treatment was administered to four replicates of twenty birds. The variables were heat stress (34 ? 2 ˚C for 8 hours) and savory extract (0.4 ml/L) in drinking water. Feed intake (FI), weight gain (WG) and feed conversion ratio (FCR) were measured in successive weeks of the trial. The relative weights of different organs (dressing, breast, thigh, liver, heart, spleen and bursa of Fabricius) determined at 42 days. The serum glucose and blood plasma content

Abstract

Background: The importance of Candida albicans as the most common cause of fungal infections in humans is undeniable. Genotyping methods have been developed as useful tools to differentiate between fungal strains isolated from various infections. Several molecular typing methods have been described for C. albicans, and fragment length analysis of microsatellites called microsatellite fragment length polymorphism (MLP) is one of the most accurate genotyping methods.Objectives: The present study aimed at evaluating the genetic diversity and genetic relationships among C. albicans isolates recovered from HIV-positive patients with oral candidiasis in Iran using MLP.Methods: We analyzed 30 isolates of C. albicans obtained from HIV-positive pati

Abstract

Background: Candida albicans is the most common pathogen in patients with vulvovaginitis. Secretory aspartyl proteinases (SAPs) are potential factors in the virulence of C. albicans. Antimicrobial peptides (AMPs) are recognized as a promising antimicrobial group of drugs with a membrane degradation mechanism. Occurrence of resistance to these drugs is quite rare. The impact of rapid membrane degradation on AMPs is relative to the prevention or delay in drug resistance mechanisms in different microbes.Objectives: The purpose of this study was to compare the inhibitory effects of the designed NK95 peptide and caspofungin on expression of SAP4-SAP6 genes from clinical vaginal isolates of C. albicans.Methods: In this experimental study, samples

Journal PapersIranian journal of microbiology , Volume 8 , Issue 6, 2016 December , {Pages 401 }

Abstract

Materials and Methods:Vaginal samples of 68 women with suspected vaginitis were obtained and cultured. Canida albicans species were identified using phenotypic and genotyping methods. Spectrophotometry was used to investigate the presence of SAP protein in the vaginal samples, and SDS-PAGE was used to confirm its protein composition. Real-time PCR was performed to ascertain the effects of subinhibitory concentrations of Echinophora platyloba extract, carvacrol and caspofungin on the expression of SAP1-3 genes before and after treatment.Results:C. albicans was found as the abundant species (59.6%), and different amounts of SAP were present in all vaginal samples, which were higher than Candida krusei strain. The protein composition of SAP in

Journal PapersPathobiology Research , Volume 19 , Issue 3, 2016 November 10, {Pages 59-72 }

Abstract

Objective: Candida albicans (C. albicans) is an opportunistic yeast that can lead to pathogenesis in immunocompromised individuals and under suitable conditions. Medicinal plants ingredients such as camphor can reduce the expressions of genes involved in virulence of the fungi through their antifungal properties. The products of INT1 and EFG1 are implicated in inducing filamentous growth and adhesion of C. albicans to the host tissues. Both of these characteristics are very important in its virulence. The present study focuses on the evaluation of the effects of camphor on INT1 and EFG1 expressions at three time points of treatment (24, 48, and 72 hours) via real-time PCR. Methods: We prepared serial dilutions of camphor (1, 2, 4, 8, 16, 32
