INTRODUCTION Hospital infections caused by Candida spp. are a leading cause of morbidity and mortality in hospitalized patients, particularly those that are critically ill or immunocompromised. In this study, the distribution of Candida species in isolates from the University Hospital of the Federal University at Grande Dourados and their in vitro(More)
INTRODUCTION The indiscriminate use of antimicrobials has selected for the emergence of resistant strains. Many mechanisms contribute to the spread of antimicrobial-resistant genes, and integrons play a key role in this process. The aim of this study was to describe the serotypes and resistance profiles, and to characterize the presence of integrons in(More)
Background The term candiduria can be defined as the observation of yeasts on direct examination of urine through the presence of pseudo-hyphae and fungal growth in urine culture [1]. The yeast Candiduria can be detected in the urine in patients who have bladder colonization and in patients who have urinary tract infection [2]. Currently, there are few(More)
This paper presents the development of an application for the operational system Android (Android OS) with the intent of controlling embedded systems via Bluetooth. The system to be operated is a teleoperated vehicle for remote sensoring and environmental damage detection. This prototype remotecontrolled vehicle was developed using the open-source(More)
The azoles are the class of medications most commonly used to fight infections caused by Candida sp. Typically, resistance can be attributed to mutations in ERG11 gene (CYP51) which encodes the cytochrome P450 14α-demethylase, the primary target for the activity of azoles. The objective of this study was to identify mutations in the coding region of(More)
BACKGROUND Candida tropicalis is an emerging major human pathogen in nosocomial infections, and it is considered the second or third species of Candida most isolated from urine cultures. AIMS The study aimed at characterizing genotypically C. tropicalis strains from patients with candiduria in a university hospital, and assessed the antifungal(More)
The aim of this study was to evaluate the effect of the replacement of corn with cassava peel in the diets of dairy cows. Eight Holstein cows were used. The experimental treatments consisted of four replacement levels of corn with cassava peel (0, 33, 66, and 100 %). The replacement of corn with cassava peel linearly decreased the intake and digestibility(More)
Background The candiduria can be defined as the observation of yeasts in urine examination [1]. The ability of yeast to adhere, to infect and cause the disease in the set is defined as a potential virulence or pathogenicity [2]. Virulence factors expressed by Candida species may vary depending on the type of infection, the location and the stage of the(More)
In this study, the culture analysis of urine samples from patients hospitalized in the Central-West region of Brazil was performed, and the isolated microorganisms were phylogenetically identified as Trichosporon asahii. Maximum parsimony analysis of the IGS1 sequences revealed three novel genotypes that have not been described. The minimum inhibitory(More)
Myracrodruon urundeuva is a plant native to Brazil, which is used by the indigenous population for the treatment of candidiasis. The aims of this study were to evaluate the antifungal activity of extract against human vaginal Candida species and evaluate the possible toxicological activities of M. urundeuva. Initially, ethanol extracts, ethyl acetate(More)
