Caged-hypocrellin mediated photodynamic therapy induces chromatin remodeling and disrupts mitochondrial energy metabolism in multidrug-resistant Candida auris

mycolabadmin

Researchers developed a new photodynamic therapy treatment using a light-activated compound called COP1T-HA to fight drug-resistant Candida auris infections. The therapy works by reorganizing the fungal cell’s genetic material architecture and disrupting energy production in mitochondria, ultimately killing the fungal cells. This approach represents a novel strategy to overcome antibiotic resistance, as it targets multiple cellular processes rather than a single pathway that fungi can easily resist.

Endophytic Diversity in Sicilian Olive Trees: Identifying Optimal Conditions for a Functional Microbial Collection

mycolabadmin

Researchers studied beneficial microorganisms living inside olive trees in Sicily to understand how to boost plant health and disease resistance. They found that wild olive trees and woody twigs harbor more diverse and beneficial microbes than cultivated varieties. Bacillus bacteria were particularly valuable, producing compounds that protect plants and promote growth. These findings could help farmers reduce chemical inputs while improving olive production.

New insights toward personalized therapies for vulvovaginal candidiasis and vaginal co-infections

mycolabadmin

Vaginal yeast infections (vulvovaginal candidiasis) and bacterial vaginosis are very common conditions affecting millions of women worldwide. Current treatments often fail or lead to antibiotic resistance. This review explores new personalized approaches including zinc supplementation, specific probiotics, and immune-boosting therapies that are tailored to each woman’s unique vaginal environment to prevent recurring infections.

An Efficient Microwave Synthesis of 3-Acyl-5-bromoindole Derivatives for Controlling Monilinia fructicola and Botrytis cinerea

Researchers created new chemical compounds based on indoles that can kill harmful fungi affecting fruit crops. These compounds were made using microwave energy, which made the synthesis faster and more efficient. Testing showed that some of these new compounds worked better at stopping fungal growth and spore germination than currently used commercial fungicides, making them promising candidates for protecting fruit crops from rot diseases.

An Atypical Presentation of Allergic Bronchopulmonary Aspergillosis

A 57-year-old man without prior lung problems developed a persistent cough and breathing difficulties that didn’t respond to antibiotics. Imaging showed his lung had collapsed and fluid had accumulated around it, raising concerns about cancer. However, bronchoscopy revealed the collapse was caused by thick mucus plugs filled with Aspergillus fungus rather than cancer. After treatment with antifungal medication and steroids, the patient fully recovered with his lung re-expanding and fluid resolving.

Disseminated sporotrichosis caused by Sporothrix brasiliensis with testicular involvement

mycolabadmin

This case report describes a rare fungal infection caused by Sporothrix brasiliensis in a 35-year-old man living with HIV/AIDS. The infection spread throughout his body, affecting his skin, lungs, brain, and testicles. Doctors initially thought the testicular involvement was cancer and removed the testicle, but lab tests confirmed it was a fungal infection. The patient was successfully treated with antifungal medications and remains disease-free one year later.

Identification and biological characterization of pathogen causing sooty blotch of Ardisia crispa (Thunb.) A.DC.

mycolabadmin

Researchers identified two fungi causing sooty blotch, a serious disease affecting Ardisia crispa, an important Chinese medicinal plant. The disease creates black mold on leaves that reduces the plant’s ability to produce energy through photosynthesis. The study found that extracts from specific medicinal plants can effectively inhibit the growth of these harmful fungi, offering an environmentally friendly alternative to chemical pesticides for protecting these valuable medicinal plants.

Past, present and future of antifungals: Advancements in mechanisms of action and resistance

mycolabadmin

Fungal infections are a growing global health problem, particularly for people with weakened immune systems, causing millions of deaths annually. Current antifungal medications are limited and increasingly ineffective due to drug-resistant fungi. This special issue explores new treatment strategies including novel drugs, combination therapies, and innovative approaches like nanoparticles and antimicrobial peptides to combat these serious infections.

Low Antigen Titre Disseminated Cryptococcosis in Immunocompromised Hosts: Two Challenging Case Reports

mycolabadmin

Two patients with weakened immune systems developed serious fungal blood infections from Cryptococcus despite having unusually low levels of fungal markers in their blood. One was a kidney transplant patient and the other had HIV. Neither showed signs of brain infection, which is unusual for this disease. Both were successfully treated with aggressive antifungal medications once blood cultures confirmed the disseminated infection.

Formulation, characterization, and in vitro antifungal evaluation of liposomal terbinafine prepared by the ethanol injection method

mycolabadmin

Researchers developed a new way to deliver the antifungal drug terbinafine using tiny fat-based particles called liposomes. These particles are designed to carry the drug more effectively to infected tissues while reducing harmful side effects. The optimized formulation showed promise for treating stubborn fungal infections, especially those affecting the brain, with significantly reduced toxicity compared to the drug alone.
