(MeOPhSe)2, a synthetic organic selenium compound, inhibits virulence factors of Candida krusei: Adherence to cervical epithelial cells and biofilm formation.
We delved into the potential of a synthetic organic selenium compound, known as p,p'-methoxyl-diphenyl diselenide, or (MeOPhSe), to combat candidiasis, particularly focusing on its effects on Candida krusei. This research is important because Candida species can lead to both mild and serious infections, and finding effective treatments is crucial.
Our study demonstrated that (MeOPhSe) is non-toxic to human cells, such as cervical epithelial and fibroblastic cells, and has a notable antifungal effect. We observed that it inhibited the growth of C. krusei in a dose-dependent manner, altering its growth pattern and extending the length of its lag phase. Most significantly, we found that this compound reduced the ability of both C. krusei and C. albicans to adhere to human cells, a critical step in the infection process.
The reductions we measured were substantial: C. krusei adherence dropped by 37.24%, while C. albicans showed a 32.84% reduction, both being statistically significant. Interestingly, both species responded similarly to (MeOPhSe), highlighting its potential as a broad-spectrum antifungal agent against various Candida infections.
Overall, our findings suggest that (MeOPhSe) holds promise as an antifungal treatment targeting the virulence factors of different Candida species, paving the way for new treatment options in battling candidiasis.

Selenium nanoparticles inhibit candidiasis
Inhibition of Candida albicans biofilm by pure selenium nanoparticles synthesized by pulsed laser ablation in liquids.
We explored the effects of selenium nanoparticles on Candida albicans, particularly focusing on their ability to inhibit biofilm formation. The nanoparticles were created using a cutting-edge technique known as femtosecond pulsed laser ablation in de-ionized water, ensuring they were free from contaminants.
Our observations revealed that these pure selenium nanoparticles could effectively attach to the biofilm of Candida albicans. Once adhered, the nanoparticles penetrated the pathogen and began to disrupt its cellular structure by substituting sulfur. Remarkably, we achieved a 50% reduction in biofilm formation at a low concentration of just 25 parts per million (ppm).
Furthermore, our analysis highlighted two important factors affecting the effectiveness of the selenium treatment: the crystallinity and size of the particles. This study suggests that pure selenium nanoparticles hold promising potential for advancing future treatments for candidiasis by targeting harmful biofilm formations.

Selenium's potential against candidiasis
Evaluating the anti- effects of selenium nanoparticles impregnated in acrylic resins: An in vitro study.
We focused on the effectiveness of selenium nanoparticles (SeNPs) incorporated into acrylic resins to combat candidiasis, specifically in the context of denture-induced stomatitis. Current treatments often come with side effects and can lead to drug resistance, making this research particularly relevant.
Our study involved formulating acrylic resins with varying concentrations of SeNPs—0.2, 2, and 10 g/mL—and testing them against clinical isolates. We determined the minimum inhibitory concentration (MIC) and developed fungal biofilms on acrylic samples, assessing the level of biofilm through various methods, including scanning electron microscopy (SEM).
We found that the MIC for SeNPs stood at 25%, with the highest antifungal activity observed at a concentration of 10%. The optical density measurements indicated that the 10% SeNPs group effectively reduced biofilm formation compared to lower concentrations. SEM analysis confirmed significant damage to the fungal cell walls, aligning with our findings of decreased colonization.
These results suggest that selenium nanoparticles can be a promising alternative treatment for candidiasis, particularly for those wearing dentures. Their ability to inhibit fungal growth demonstrates SeNPs' potential in addressing oral health issues connected to candidiasis.

Frequently Asked Questions
Candidiasis, commonly known as a yeast infection, is an infection caused by the overgrowth of Candida, a type of fungus that naturally occurs in various locations in the body, including the mouth, gut, and vagina. Under normal circumstances, Candida exists in balance with other microorganisms, but factors such as antibiotic use, high sugar diets, and compromised immune systems can disrupt this balance, leading to an overgrowth. This can manifest in various forms, including oral thrush (affecting the mouth), vaginal yeast infections, and invasive candidiasis (which can affect the bloodstream and internal organs).
Symptoms of candidiasis vary depending on the area affected; for example, a vaginal yeast infection can cause itching, burning, and unusual discharge, while oral thrush may lead to white patches in the mouth, soreness, and difficulty swallowing. Treatment typically involves antifungal medications, which can be prescribed or obtained over-the-counter, depending on the severity and type of the infection. To prevent recurrence, it's essential to maintain a healthy diet, manage stress, and practice good hygiene. If you suspect you have candidiasis, particularly in more severe cases, consulting a healthcare provider is recommended for appropriate diagnosis and treatment options.

Candida infection worsened by selenium deficiency
The response of selenium-deficient mice to Candida albicans infection.
We explored how a lack of selenium affects the body's response to Candida albicans infections in mice. Our study involved comparing selenium-deficient mice with those who received selenium supplements by giving them injections of the fungi.
It was observed that the selenium-deficient mice began to show signs of severe illness and eventually succumbed to the infection much sooner than the supplemented group—with deaths occurring just 2.5 to 3.5 days post-injection, compared to 7 to 8.5 days for those receiving selenium.
Additionally, the selenium-deficient mice had a significantly higher presence of Candida albicans in their kidneys, livers, and spleens three days after the injections. This suggests that selenium plays a crucial role in the immune response, particularly in how neutrophils—a type of white blood cell—handle fungal infections.
The study highlights a clear relationship between selenium deficiency and reduced resistance to candidiasis, demonstrating how important this trace element is for our immune health, particularly in fighting off infections.

Selenium's impact on candidiasis
An in vivo and in vitro study of selenium deficiency and infection in rats.
We examined the effects of selenium deficiency on the ability of rats to fight off Candida albicans, a common fungus that can cause infections. The study showed that when rats lacked adequate selenium, their neutrophils and peritoneal macrophages—key cells in the immune system—struggled to kill these fungal organisms in laboratory settings.
Interestingly, selenium deficiency did not seem to impact the rats' ability to tackle other bacteria, such as Salmonella typhimurium and Staphylococcus aureus, suggesting a specific vulnerability when it came to yeast infections like candidiasis.
Moreover, when rats were injected with a large dose of Staphylococcus aureus, their survival rates were comparable regardless of selenium levels. However, an increased bacterial load led to higher mortality in selenium-deficient rats, hinting that while selenium's role is critical in dealing with some pathogens, its deficiency has a notable impact on fungal infections.
Overall, the findings emphasize that selenium might be essential for effectively combating candidiasis while not influencing the response to certain bacterial infections. This insight can inform future research and nutritional guidelines regarding selenium's importance in immune health.
