Aspergillus latus: A cryptic causative agent of aspergillosis emerging in Japan

mycolabadmin

Researchers in Japan discovered that a dangerous fungus called Aspergillus latus, previously unknown in the country, has been causing infections since at least 2013. This fungus is difficult to identify because it looks similar to other related species and is actually a hybrid created from two different Aspergillus species. The study found seven cases of this fungus in clinical samples and discovered that it is resistant to some common antifungal medications, making accurate identification crucial for proper patient treatment.

Multi-omics Analysis of Experimentally Evolved Candida auris Isolates Reveals Modulation of Sterols, Sphingolipids, and Oxidative Stress in Acquired Amphotericin B Resistance

mycolabadmin

Researchers studied how the fungus Candida auris develops resistance to amphotericin B, an important antifungal drug. By evolving two laboratory strains of this fungus under drug pressure, they discovered two different ways the fungus can become resistant: one through stress management genes, the other through changes in its protective lipids. These findings help explain why some clinical infections with this dangerous fungus are so hard to treat.

A case report of Saksenaea vasiformis mucormycosis infection of a lower segment caesarean section wound

mycolabadmin

A young woman developed a rare fungal infection (mucormycosis) in her caesarean section wound seven days after surgery. Despite initial antibiotic treatment, she required multiple surgical debridement procedures combined with antifungal medications to eliminate the infection. The surgical team successfully reconstructed her abdominal wall using specialized mesh and skin grafting techniques, resulting in complete healing.

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.
