Improving the production of micafungin precursor FR901379 in Coleophoma empetri using heavy-ion irradiation and its mechanism analysis

mycolabadmin

Scientists successfully improved the production of a key ingredient for the antifungal drug micafungin by using heavy-ion radiation to create improved strains of a fungus called Coleophoma empetri. The best mutant strain produced over 250% more of the desired compound than the original strain. By analyzing the genetic changes in these improved strains, researchers identified specific genes related to fungal structure and metabolism that contribute to higher production, providing insights for future improvements to the manufacturing process.

Erythema Nodosum Associated with Kerion: A Case Series and Narrative Review of the Literature

mycolabadmin

This paper describes a rare condition where patients develop painful red bumps on the shins (erythema nodosum) as a reaction to a severe scalp fungal infection (kerion) caused by Trichophyton mentagrophytes. The authors reviewed 23 similar cases and found that this reaction usually happens during antifungal treatment and resolves within about a week. Treatment with antifungal medications like griseofulvin, sometimes combined with anti-inflammatory steroids, is effective, though scarring of the scalp may remain.

Randomized control trial to study the effectiveness of tablet Fluconazole, capsule Itraconazole and tablet Terbinafine in superficial dermatophytosis

mycolabadmin

This study tested three common antifungal medications used to treat fungal skin infections like ringworm. The research involved 180 patients who were randomly given one of three drugs and then checked at 4 and 8 weeks to see if the infection was gone. Itraconazole worked best, clearing infections in about 87% of patients, followed by Fluconazole at 73%, and Terbinafine at 63%.

Histoplasma capsulatum prosthetic valve endocarditis treated with oral isavuconazole

mycolabadmin

A 76-year-old man developed a rare fungal infection of his artificial heart valve caused by Histoplasma capsulatum. After surgically replacing the infected valve, he was treated with isavuconazole, an antifungal medication taken by mouth. Unlike traditional antifungal treatments, isavuconazole was better tolerated and easier to take. The patient successfully recovered after nine months of treatment with no complications.

Progress of Antimicrobial Mechanisms of Stilbenoids

mycolabadmin

Stilbenoids are natural compounds found in plants that can fight harmful bacteria and fungi in multiple ways. Unlike traditional antibiotics that only kill microbes, stilbenoids can also prevent infections by disrupting biofilm formation and weakening pathogen virulence. These compounds show promise in combating drug-resistant infections without promoting further resistance development, making them valuable candidates for new antibiotic medicines.

Inhibitory Effects and Mechanisms of Perilla Essential Oil and Perillaldehyde against Chestnut Pathogen Botryosphaeria dothidea

mycolabadmin

Chestnuts often rot during storage due to fungal infection. This study found that oil extracted from perilla leaves, particularly a compound called perillaldehyde, effectively prevents the fungus Botryosphaeria dothidea from growing. The antifungal compounds work by breaking down the protective layers of the fungal cells, causing them to leak and die. When applied to stored chestnuts, this natural oil significantly extends their shelf life without harming human health.

Synergistic potential and apoptosis induction of Bunium persicum essential oil and its pure components, cuminaldehyde and γ-terpinene, in combination with fluconazole on Candida albicans isolates: in vitro and in silico evaluation

mycolabadmin

Researchers tested how Bunium persicum essential oil and its components work alongside the antifungal drug fluconazole against Candida albicans infections. Cuminaldehyde, a major component of the oil, showed the strongest effects when combined with fluconazole, making infection-causing cells die faster than each substance alone. This combination approach could help overcome drug-resistant fungal infections and offers a promising natural alternative to synthetic drugs alone.

FTIR Characterization and Bioactivity Assessment of Cinnamomum camphora Essential Oil: Antioxidant, Anti-Enzymatic, and Antifungal Properties Against Phytopathogens

mycolabadmin

Camphor tree essential oil has been studied for its ability to fight fungal diseases that harm crops and its potential health benefits. The research found that this natural oil completely stops the growth of several harmful fungi at high concentrations, making it a promising eco-friendly alternative to synthetic pesticides. The oil also showed antioxidant properties and may help regulate blood sugar levels, suggesting uses in both agriculture and medicine.

Dermatophytosis caused by Trichophyton benhamiae in a sea lion. First report

mycolabadmin

A 13-year-old sea lion in a marine park developed ringworm-like skin lesions caused by a fungus called Trichophyton benhamiae, marking the first time this fungus has been identified in this species. Scientists identified the fungus using DNA testing and found it was resistant to common antifungal drugs, so they treated it with a combination of oral medication (terbinafine), topical ozonized oil, and a liver-protecting supplement. After three months of treatment, the sea lion’s skin healed completely.

Rhino sinusitis caused by Lasiodiplodia theobromae in a diabetic patient

mycolabadmin

A 56-year-old diabetic man developed a sinus infection caused by a rare fungus called Lasiodiplodia theobromae, which typically affects plants. The infection was diagnosed through laboratory testing and DNA sequencing, as traditional identification methods were inconclusive. The patient was successfully treated with a combination of sinus surgery and a six-week course of antifungal medication, showing complete recovery after one year of follow-up.
