Fungal Species: Mucor

Catastrophic Cerebral Infarctions in a Pediatric Patient with Acute Lymphoblastic Leukemia Due to Mucorales Infection

mycolabadmin

An 11-year-old girl with leukemia undergoing chemotherapy developed a severe fungal infection called mucormycosis caused by Lichtheimia ramosa. The infection spread rapidly from her sinuses to her eyes and brain, causing multiple blood clots in brain arteries and a massive stroke within just five days. Despite emergency surgery to remove the clots, the infection had progressed too far and the patient sadly did not survive, highlighting how dangerous this fungal infection can be in children with weakened immune systems.

Optimizing a modified cetyltrimethylammonium bromide protocol for fungal DNA extraction: Insights from multilocus gene amplification

mycolabadmin

Researchers developed an improved method for extracting fungal DNA that is faster, cheaper, and safer than current commercial kits. The new protocol works by using a special chemical solution and simple crushing tools instead of expensive equipment like liquid nitrogen or bead beaters. They tested it on 40 different fungal species found in dry fruits and successfully identified them all using genetic markers, showing the method could help diagnose fungal diseases in plants, animals, and humans.

Epidemiology of mucormycosis in COVID-19 patients in northwest Iran: Rhizopus arrhizus as the predominant species

mycolabadmin

During the COVID-19 pandemic, some patients developed a severe fungal infection called mucormycosis alongside their coronavirus infection. This study found that 63 COVID-19 patients in Iran developed mucormycosis, which primarily affected the sinuses and brain. The researchers identified that a fungus called Rhizopus arrhizus caused most infections, and patients who received corticosteroids (used to treat severe COVID-19) had a higher risk, especially those who developed diabetes from the steroids.

Unraveling the mycobiota of Daqu at the species level using metabarcoding of full-length ITS sequences

mycolabadmin

Daqu is a special fermentation starter used to make Baijiu, a traditional Chinese alcohol. Researchers analyzed fungi in 296 Daqu samples from across China using advanced DNA sequencing technology. They identified 86 different fungal species and found that the types of fungi present depend on both the temperature during fermentation and the geographic region where the Daqu is made. These findings could help improve the quality and consistency of Baijiu production.
