Synergistic inhibition of Aspergillus flavus by organic acid salts: growth, oxidative stress, and aflatoxin gene modulation

mycolabadmin

A dangerous fungus called Aspergillus flavus contaminates animal feed and produces harmful toxins called aflatoxins that can make animals sick. Researchers tested a combination of three salt-based organic acids commonly used as natural food preservatives and found they work together to kill this fungus much better than using them individually. The combination damages the fungus’s cell structure, creates harmful reactive oxygen inside the cells, and shuts down the genes that produce the toxins, making it an excellent safe option for protecting animal feed.

The Efficacy of Clove Oil Against Aspergillus flavus and the Production of Aflatoxin B1 in Organic Peanuts in Georgia

mycolabadmin

Researchers tested clove essential oil as a natural antifungal treatment for peanuts infected with a mold that produces aflatoxin, a dangerous toxin harmful to human health. They found that clove oil significantly reduced both the mold growth and toxin production, with the best results at moderate concentrations. This discovery offers organic farmers an eco-friendly alternative to synthetic fungicides for protecting their peanut crops. The findings could help reduce a major agricultural problem that costs the Southeast millions of dollars annually.

The Effect of Aspergillus flavus on Seedling Development in Maize

mycolabadmin

Aspergillus flavus is a dangerous fungus that contaminates maize crops and produces toxic aflatoxins harmful to human and animal health. Researchers tested maize varieties to identify which are naturally resistant to this fungus using a simple laboratory method. They found significant differences in resistance among maize varieties and proposed a new evaluation system to help identify resistant varieties before they are sold to farmers, which could help reduce aflatoxin contamination in our food supply.

Stonebrood Disease—Histomorphological Changes in Honey Bee Larvae (Apis mellifera) Experimentally Infected with Aspergillus flavus

mycolabadmin

Stonebrood is a rare fungal disease of honey bees caused by Aspergillus flavus that can kill bee larvae very quickly. Researchers experimentally infected bee larvae with the fungus and tracked how the disease progressed, finding that larvae died within 48 hours of infection. The study revealed that the fungus likely kills bees by producing toxins rather than by physical damage, and poses a health risk to beekeepers who inhale the fungal spores.

Dual fungal endocarditis in a pediatric dialysis patient: First case of Aspergillus flavus and Candida parapsilosis co-infection

mycolabadmin

A 13-year-old boy with kidney disease requiring dialysis developed a rare dual fungal heart infection caused by two different fungi simultaneously. Doctors diagnosed the infection using heart imaging, blood tests, and tissue examination, then treated him with antifungal medications and two heart surgeries to remove infected tissue and replace a damaged heart valve. Despite the extreme rarity and severity of this condition, the patient survived, which had never been reported in children before.

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

mycolabadmin

Scientists tested a plant called Urginea epigea and special tiny particles made of silver and zinc to stop a dangerous fungus called Aspergillus flavus from growing and producing aflatoxins, which are harmful poisons found in food. When used at the right concentration, the plant extract completely stopped the fungus from growing. The treatment worked by turning off the fungus’s ability to make the poison by reducing the activity of specific genes. This natural approach could offer a safer alternative to chemical fungicides for protecting our food supply.

Antagonistic Potential of Agro-Industrial Byproduct–Derived Lactic Acid Bacteria Against Mycotoxigenic Aspergillus flavus and Fusarium verticillioides

mycolabadmin

Researchers discovered that certain lactic acid bacteria found in food waste products can effectively prevent the growth of harmful fungi and block the production of dangerous mycotoxins. These bacteria work through multiple mechanisms including acidification and production of protective compounds. The findings suggest these natural bacteria could be used as safe, sustainable alternatives to chemical fungicides in food preservation and safety.

Evaluation of Aspergillus flavus Growth on Weathered HDPE Plastics Contaminated with Diesel Fuel

mycolabadmin

Diesel storage tanks made from plastic accumulate stubborn hydrocarbon residues that are difficult to clean using traditional methods. Scientists discovered that a common fungus called Aspergillus flavus can effectively grow on and potentially help break down these diesel-contaminated plastics, especially when the diesel has aged for years and is exposed to warmer temperatures. This research suggests fungi could offer an environmentally friendly way to clean up contaminated plastic waste from fuel storage.

In Vitro Activity of Nitroxoline (5-Nitro-8-Hydroxyquinoline) Against Aspergillus Species

mycolabadmin

Researchers tested an old antibiotic called nitroxoline against Aspergillus fungi that cause serious infections in immunocompromised patients. The drug works by removing zinc that the fungus needs to survive. The study found that nitroxoline was very effective against all tested fungal strains, including those resistant to modern antifungal drugs, suggesting it could potentially be repurposed as a new treatment option.
