Evaluation of Antifungal Activity Against Candida albicans Isolates From HIV-Positive Patients with Oral Candidiasis in a Major Referral Hospital, West Java, Indonesia

mycolabadmin

This study examined fungal infections in HIV-positive patients suffering from oral candidiasis (mouth thrush) in Indonesia. Researchers identified the types of Candida fungi present and tested their resistance to four common antifungal medications. Most patients had Candida albicans, and while these fungi generally responded well to newer antifungal drugs like voriconazole and fluconazole, some showed resistance, particularly to fluconazole, suggesting the need for careful testing before prescribing treatment.

Efficacy of Rezafungin on Candida albicans Endophthalmitis in a Rabbit Model

Researchers tested a new antifungal medication called rezafungin to treat a serious eye infection caused by the fungus Candida albicans. Using rabbit models, they found that rezafungin was much more effective than two other antifungal drugs at clearing the infection from the eye and preventing damage to vision. The drug’s ability to work for longer periods with less frequent dosing makes it a promising candidate for treating this devastating infection in patients.

Inhibitive effect of Urginea epigea methanolic extract and silver/zinc oxide nanoparticles on Aspergillus and aflatoxin production

Researchers tested whether a plant called Urginea epigea could stop the growth of a dangerous fungus (Aspergillus flavus) that produces aflatoxins, which can harm humans and animals. The plant extract completely stopped fungus growth at high concentrations and significantly reduced the production of toxins by turning off the genes responsible for toxin production. This suggests that plant-based treatments could offer a natural alternative to synthetic chemical fungicides for protecting food from contamination.

Chilean Aloysia Essential Oils: A Medicinal Plant Resource for Postharvest Disease Control

Researchers tested essential oils from two Chilean herbs, Aloysia citriodora and Aloysia polystachya, against fungi that cause fruit rot after harvest. They found that oil from Aloysia citriodora, especially a compound called farnesol, effectively killed the disease-causing fungi in laboratory tests. These natural oils could replace synthetic fungicides that are becoming less effective and harmful to the environment, offering farmers a safer way to protect their fruit during storage and transport.

Evaluation of antifungal effect of amphotericin B in comparison with nystatin on Candida species derived from patients undergoing head-and-neck radiotherapy

mycolabadmin

This study compared two antifungal medications (nystatin and amphotericin B) for treating oral yeast infections in cancer patients receiving head-and-neck radiotherapy. Researchers tested how well each drug worked against different Candida yeast species before and during radiation treatment. The results showed that nystatin was more effective than amphotericin B at killing the yeasts, with nystatin working against all yeast species tested, while amphotericin B had reduced effectiveness against some Candida albicans strains.

Recent innovations and challenges in the treatment of fungal infections

mycolabadmin

Fungal infections are becoming more common and dangerous, especially for people with weakened immune systems, and many fungi are developing resistance to current medications. Doctors and researchers are developing new treatment strategies, including combining multiple drugs together and using advanced technologies to deliver medicines more effectively to infected areas. Natural compounds from plants and new biotechnology tools like genetic engineering and nanoparticles show promising results for fighting drug-resistant fungal infections.

Antifungal potential of Rhinacanthus nasutus extracts against the pathogenic fungus Cryptococcus neoformans

mycolabadmin

Researchers studied snake jasmine (Rhinacanthus nasutus), a plant used in traditional Thai medicine, to see if it could fight fungal infections caused by Cryptococcus neoformans, a dangerous pathogen that kills many people worldwide. They found that extract from the plant’s roots effectively slowed fungal growth and weakened the pathogen’s defenses by reducing its ability to produce protective melanin and capsules. Importantly, when combined with amphotericin B, a common antifungal drug, the plant extract worked even better together, suggesting it could enhance existing treatments.

Biocontrol of citrus fungal pathogens by lipopeptides produced by Bacillus velezensis TZ01

mycolabadmin

Scientists discovered a beneficial bacterium called Bacillus velezensis that can protect citrus fruits from harmful fungi. This bacterium produces natural compounds called lipopeptides that kill disease-causing fungi without the need for chemical fungicides. The lipopeptides are stable and effective across different environmental conditions, making them promising for use in citrus farming as an eco-friendly alternative to traditional pesticides.

A case of rare fungal keratitis caused by Pseudoshiraia conidialis

mycolabadmin

A 61-year-old woman scratched her eye with a bamboo branch and developed a serious fungal eye infection caused by a rare fungus called Pseudoshiraia conidialis. This is the first reported case of this particular fungus infecting human eyes. Although initial treatment with antifungal medications showed promise, the infection proved difficult to cure due to the fungus being resistant to multiple antifungal drugs. The case highlights the importance of early diagnosis and treatment of fungal eye infections.

Deep cutaneous fungal infection in an immunocompetent individual caused by a biological pesticide: a rare case report

mycolabadmin

A 66-year-old farmer developed a deep skin fungal infection from a biological pesticide she used for over 10 years. The pesticide contained a fungus called Purpureocillium lilacinum, which is normally harmless to healthy people but caused repeated skin lesions on her face and arms. She was successfully treated with antifungal medication (itraconazole) for three months, and her skin fully healed without returning. This is the first reported case showing that biological pesticides can pose health risks to workers who handle them regularly.
