Aspergillus terreus sectorization: a morphological phenomenon shedding light on amphotericin B resistance mechanism

mycolabadmin

When Aspergillus terreus fungi are grown in laboratory conditions for extended periods, they sometimes undergo changes that make them look different and behave differently. Scientists found that these changed strains become more susceptible to amphotericin B, a common antifungal drug. By studying the genes and proteins in both the original and changed strains, researchers discovered that special proteins called P-type ATPases appear to be responsible for the fungus’s natural resistance to this drug, offering new targets for developing better antifungal treatments.

Basidiobolomycosis caused by a rare species – Basidiobolus meristosporus

mycolabadmin

A five-year-old girl developed large swollen lumps on her buttock and thigh that were initially thought to be tuberculosis or cancer. Doctors took a tissue sample and found it was caused by a rare fungus called Basidiobolus meristosporus. Using advanced DNA sequencing techniques, they identified the exact fungus species and treated her successfully with an antifungal medication called itraconazole, leading to complete healing within six weeks.

Antagonistic mechanism of Bacillus velezensis HX0039 as a biocontrol agent against Trichoderma virens-induced ‘Sanghuang’ green mold

mycolabadmin

Scientists discovered a beneficial bacteria called Bacillus velezensis HX0039 that can protect ‘Sanghuang’ mushrooms from harmful green mold disease. This bacteria produces natural antifungal compounds like iturin A that stop the disease without harming the mushrooms or the environment. Testing showed it was 83% effective at preventing green mold and was completely safe for both mushroom cultivation and animal consumption, making it a promising alternative to chemical fungicides.

Appearance of Environment-Linked Azole Resistance in the Aspergillus fumigatus Complex in New Zealand

mycolabadmin

Researchers in New Zealand have discovered that a dangerous fungus called Aspergillus fumigatus is developing resistance to commonly used antifungal medications. Unlike previous cases where the resistance came from medical treatment, this new resistance appears to come from environmental exposure, possibly through garden fungicides that people can buy at garden centers. The study found that people, especially lung transplant patients, may be acquiring these resistant fungal strains from their surroundings rather than from hospitals, highlighting the need for better monitoring of agricultural fungicide use.

Treatment and diagnostic challenges associated with the novel and rapidly emerging antifungal-resistant dermatophyte, Trichophyton indotineae

mycolabadmin

A new type of fungal infection called Trichophyton indotineae has emerged and spread globally, particularly from India. It causes widespread skin infections that are difficult to treat because the fungus resists common antifungal medications. Doctors and laboratories need to be aware of this infection to properly identify it and choose effective treatments, especially for patients with travel history to affected regions.

Candida albicans bloodstream infections are comprised of diverse populations of strains, including antifungal tolerant strains that emerge during treatment failure

mycolabadmin

Researchers found that Candida albicans bloodstream infections contain multiple different strains, not just one strain as previously thought. Some strains are more tolerant to antifungal medications like micafungin, and when treatment is started, the drug-tolerant strains can be eliminated while drug-sensitive strains increase in number. This discovery suggests that treatment failures may occur because pre-existing drug-resistant strains are selected for during treatment.

Infection caused by a cryptic fungal species, Blastomyces gilchristii, in a tiger

mycolabadmin

A tiger at a veterinary hospital developed a serious fungal infection that affected its brain and lungs. Using advanced DNA sequencing technology, researchers identified the infection was caused by a previously unrecognized fungal species called Blastomyces gilchristii. This discovery was important because it showed that this dangerous fungus exists in areas where scientists previously thought it wasn’t found, and it highlights the importance of using modern genetic testing to identify unusual infections.

Candida vulturna, the Next Fungal Menace? A Narrative Review

mycolabadmin

Candida vulturna is a newly identified fungus that causes serious bloodstream infections, particularly in newborns and hospitalized patients in tropical regions. Unlike many common fungal infections, it resists several antifungal medications, though it remains susceptible to certain antibiotics called echinocandins. Scientists have documented 94 cases worldwide, including three hospital outbreaks, and the infection has a relatively low death rate of 18%. Accurate identification requires genetic testing since standard hospital laboratory tests often misidentify this pathogen.

Whole genome sequencing and annotations of Trametes sanguinea ZHSJ

mycolabadmin

Scientists sequenced the complete genome of Trametes sanguinea, a medicinal mushroom used in traditional Chinese medicine, grown in China. The mushroom’s tissue contains beneficial compounds that may help fight tumors, protect the heart, boost immunity, and heal diabetic wounds. By mapping out all 10,886 genes in this fungus, researchers now have detailed blueprints to understand how it produces these healing compounds and potentially grow them industrially for medical use.

Renaming Candida glabrata—A case of taxonomic purity over clinical and public health pragmatism

mycolabadmin

Candida glabrata is a common yeast infection that causes serious illnesses in humans, affecting millions of people worldwide. Scientists have recently proposed renaming it to Nakaseomyces glabrata for technical taxonomic reasons. However, this article argues against the change because it would create confusion for doctors, complicate treatment instructions on medications, disrupt disease tracking systems, and make it harder for patients to understand their conditions. Keeping the familiar name Candida glabrata is more practical and helpful for patient care and public health than strict adherence to taxonomic classification rules.
