Abstract Purpose The prevalence of Candida infections has been rising with an increasingly aging population and a larger immunocompromised individuals. use probiotics may be alternative approach to antifungal agents in the prevention treatment oral candidiasis. This study aimed evaluate short‐term effect reducing infection level candidiasis‐asymptomatic elderly denture wearers. Materials Methods In double‐blind randomized study, 59 wearers harboring spp. cavity no clinical symptoms were...
A biofilm is a complex community of surface-associated cells enclosed in polymer matrix. They attach to solid surfaces and their formation can be affected by growth conditions co-infection with other pathogens. The presence may protect the microorganisms from host defenses, as well significantly reduce susceptibility antifungal agents. Pathogenic microbes form biofilms on inert implanted devices such catheters, prosthetic cardiac valves intrauterine (IUDs). present study was carried out...
The aim of this study was to investigate the influence light parameters on yeast cells. It has been proposed for many years that photodynamic therapy (PDT) can inactivate microbial A number photosensitizer and sources were reported in different a range dye concentrations. However, much more knowledge concerning importance fluence, fluence rate exposure time are required better understanding efficiency. Suspensions (106 CFU/mL) Candida albicans, krusei, Cryptococcus neoformans var. grubii...
The aim of this study is to evaluate the oral colonization by Candida albicans in experimental murine immunosuppressed DBA/2 and treatment with probiotic bacteria. To achieve these objectives, 152 DBA/2-immunosuppressed mice were orally inoculated a suspension C. containing 10(8) viable yeast cells, animals treated nystatin or probiotics (Lactobacillus acidophilus Lactobacillus rhamnosus). Evaluations performed count from mucosa swabbing. started at day 1 after inoculation, remained maximal...
Cryptococcosis has been a significant cause of morbidity and mortality in patients with Aids. Many reservoirs the agent Cryptococcus neoformans have reported, but ecology this yeast must be elucidated order to establish surveillance programs prevent infections. The objective study was evaluate presence C. Rio de Janeiro City, RJ, Brazil. Ten churches were selected for sampling detection collecting pigeon dropping, air samples from church towers neighboring areas during one year. data...
To evaluate the virulence profile of strains Cryptococcus neoformans var. grubii, 62 this yeast were inoculated into BALB/c mice. It was found that 69 % significantly more lethal to mice and recovered from a higher percentage (60 %) organs compared with other 31 strains, which 35 tested. Those provoked death rates also central nervous system at rate (84 than less (32 %). This finding led an investigation factors enhanced capacity for neurological infection animals. The results study...
A prospective study was performed to evaluate the correlation between proposed standard of Antifungal Susceptibility Testing Subcommittee European Committee on Antibiotic (AFST-EUCAST) (document 7.1) and commercial system Etest for determining MICs flucytosine, amphotericin B, fluconazole, itraconazole voriconazole a collection 100 clinical environmental isolates Cryptococcus neoformans. The agreements among within +/-2 log2 dilutions AFST-EUCAST were greater fluconazole (76, 78 88 %,...
This study compared the minimum inhibitory concentration (MIC) results from proposed standard methods of Antifungal Susceptibility Testing Subcommittee European Committee on Antibiotic (AFST–EUCAST) with commercial system Etest ® in evaluation susceptibility to flucytosine, fluconazole, itraconazole, voriconazole, and amphotericin B 136 Candida spp. isolated blood hospitalized children. The presented a greater agreement among MICs ±2 log 2 dilutions AFST–EUCAST for fluconazole (98.1% 96.3%)...
It has been proposed that photodynamic therapy (PDT) can inactivate microbial cells. A range of photosensitizers and light sources were reported as well different fluence parameters dye concentrations. However, much more knowledge regarding to the role fluences, irradiation time irradiance are required for a better understanding efficiency. The aims this study investigate on photoinactivation yeast cells, compare cell survivors in growing phases following PDT. To perform study, suspension...
This is the first report of yeast Apiotrichum veenhuisii (formerly Trichosporon veenhuisii) causing disease in humans; its virulence and vitro behavior against antifungals were also studied. The sample was isolated from biopsy fragments disseminated lesions on skin a pediatric patient with acute myeloid leukemia. studied factors evidenced that strain tested negative for secretion enzymes proteinase, phospholipase, hemolysin. isolate characterized as low biofilm producer. Except amphotericin...
Cryptococcosis is an infection caused by the encapsulated yeast Cryptococcus neoformans and most afflicted sites are lung, skin central nervous system. A range of studies had reported that photodynamic therapy (PDT) can inactivate cells; however, in vivo experimental models cryptococcosis photoinactivation not commonly reported. The aim this study was to investigate ability methylene blue (MB) combined with a low-power red laser vitro models. To perform study, suspension ATCC-90112...
O objetivo deste estudo foi investigar a influencia dos parâmetros de irradiacao na terapia fotodinâmica em leveduras. Tem sido proposto literatura que (PDT) pode matar celulas microbianas e, um grande numero fotossensibilizadores e fontes sao reportados, diferentes diversas concentracoes do corante. Entretanto, para os processos fotodinâmicos sejam entendidos, mais conhecimento sobre importância da taxa fluencia, fluencia tempo necessarios. Para isso, suspensoes Candida albicans, krusei...
Objective: As isolates of Cryptococcus are frequently kept collection stocks in institutions, sometimes without proper characterization, we sought to determine the genotype profiles, protease and phospholipase activities “in vitro” susceptibility testing for azoles amphotericin B. Methodology: 84 from several regions Brazil (40 samples clinical origin 44 environmental origin) were maintained at microorganism’s bank Biomedical Science Institute (ICB-USP) São Paulo University, Paulo, Brazil....
Background: Yeasts from the genus Cryptococcus (species C. neoformans and gattii) are opportunistic pathogens that afflict humans with low immunity caused by diseases such as AIDS or usage of immunosuppressive drugs. It is a fatal disease has been studied around whole world its most form brain cryptococcosis. Purpose: The present review describes pathogen isolation, various clinical presentations disease, important virulence factors yeast in human animal model their issues. Methods: On this...
