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.

Synthesis, Physicochemical Properties and Anti-Fungal Activities of New Meso-Arylporphyrins

mycolabadmin

Researchers created three new porphyrin compounds that effectively kill fungal infections like Candida and athlete’s foot fungi. These compounds can also generate singlet oxygen when exposed to light, making them potentially useful for photodynamic therapy treatments. Testing showed they inhibited fungal growth at relatively low concentrations, suggesting they could become new antifungal medications.

Genomic characterization and fermentation study of the endophyte Stemphylium sp. (Aa22), a producer of bioactive alkyl-resorcinols

mycolabadmin

Scientists have studied a beneficial fungus called Stemphylium sp. Aa22 that lives inside wormwood plants and produces natural insect-repelling compounds called alkyl-resorcinols. By reading the complete genetic code of this fungus, researchers identified the gene responsible for making these compounds and found that growing the fungus in liquid culture produces more of the desired compounds than growing it on solid rice. This research could lead to developing natural, environmentally-friendly pesticides to protect crops from aphids and other pests.

Frequency, Interval, and Patient Factors Associated With Recurrence of Disseminated Cutaneous Coccidioidomycosis

mycolabadmin

This study looked at how often a serious fungal skin infection called coccidioidomycosis comes back after treatment. Researchers found that about 25% of patients experienced at least one recurrence after stopping antifungal medications, with the average time before it returned being 14 months. Some patients had multiple recurrences, and most of the time the infection returned to the same location on the body.

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

mycolabadmin

Growers struggle with fungal diseases that infect grapevine nurseries, reducing the quality of planting material. Researchers tested electrolyzed water—a solution made from salt and water using electricity—as a sustainable treatment for infected grapevine cuttings. Laboratory tests showed the treatment effectively killed fungal spores and reduced fungal growth. Field trials at a commercial nursery confirmed that treating cuttings with electrolyzed water reduced certain grapevine diseases without harming plant growth.

Identification of Pseudocercospora mori as the causal agent of grey leaf spot disease in mulberry (Morus atropurpurea) from various localities in Guangdong Province, China

mycolabadmin

This study identifies the fungus Pseudocercospora mori as the cause of a serious disease affecting mulberry leaves in southern China. Researchers used microscopy, genetic testing, and laboratory experiments to confirm that this pathogen damages mulberry plants and reduces the quality of leaves used in silk production. The study provides practical diagnostic tools to help farmers detect and manage this disease in their mulberry orchards.

Effect of Dietary Insect Meal and Grape Marc Inclusion on Flavor Volatile Compounds and Shell Color of Juvenile Abalone Haliotis iris

mycolabadmin

Researchers tested whether using insect meal and grape marc as sustainable alternatives to fish meal in abalone feed would affect meat flavor and shell color. The study found that grape marc reduced unpleasant off-flavors in the meat while insect meal had minimal effect on flavor. Neither ingredient significantly changed shell color. These findings suggest these sustainable ingredients could improve both environmental impact and product quality in abalone farming.

Long term worsening of amyloid pathology, cerebral function, and cognition after a single inoculation of beta-amyloid seeds with Osaka mutation

mycolabadmin

Researchers found that a single exposure to mutated amyloid-beta proteins (Aβ Osaka) in the brains of genetically modified mice caused lasting damage over four months. The mutated proteins triggered more severe memory loss, brain connectivity problems, and synapse damage compared to normal amyloid-beta. This suggests that even one encounter with mutated amyloid proteins can set off a chain reaction of disease progression that persists long after initial exposure.

Epidermophyton floccosum, an etiological agent of tinea pedis and tinea unguium: about two cases

mycolabadmin

Two elderly patients were diagnosed with fungal nail and foot infections caused by Epidermophyton floccosum, a fungus that has become less common in recent years. Both cases were confirmed using advanced molecular testing (real-time PCR) alongside traditional laboratory methods. The infections were successfully treated with terbinafine, an antifungal medication. This case report highlights the importance of using modern diagnostic techniques to accurately identify and treat fungal infections.

Selection of reliable reference genes in Colletotrichum scovillei during different growth stages, host interactions, and plant extract treatment for qRT-PCR

mycolabadmin

This research identifies the best internal control genes to use when measuring gene activity in a fungus that causes pepper disease. Scientists tested eight different reference genes under various conditions like fungal growth and pepper infection, plus when treating the fungus with plant extracts. Different genes worked best for different situations: one gene was best during fungal growth, another during infection, and a third when treated with plant extracts. These findings will help future studies better understand how this disease-causing fungus works and develop better control methods.
