Prevalence and antifungal susceptibility profiles of Candida isolates among patients with candiduria: a multiplex PCR assay

mycolabadmin

Researchers studied fungal infections in urine samples from hospitalized patients and found that while the common yeast Candida albicans was most prevalent, other Candida species were increasingly resistant to antifungal medications. Using advanced genetic testing methods, they identified seven different Candida species and tested their resistance to three common antifungal drugs. The findings highlight the growing problem of drug-resistant fungal infections and the need for better diagnostic tools to identify which species is causing infection so appropriate treatment can be selected.

Recalcitrant dermatophytosis due to Trichophyton indotineae: A case series from Sarawak, Malaysia

mycolabadmin

Three patients in Malaysia had persistent skin fungal infections caused by Trichophyton indotineae that did not respond to standard antifungal treatments. Genetic testing revealed these fungal strains carried a specific mutation making them resistant to terbinafine, the typical first-line treatment. While azole-based antifungals showed variable effectiveness depending on the specific drug and dose used, one patient achieved complete cure with voriconazole therapy. The study highlights the growing problem of drug-resistant fungal infections and the importance of targeted treatment based on laboratory testing.

Candida krusei Empyema: A Lung Transplant Case and Systematic Review of the Literature

mycolabadmin

Candida krusei is a dangerous fungus that can cause fluid buildup around the lungs (empyema), particularly in transplant patients. Unlike common fungal infections that respond to fluconazole, this species is naturally resistant to this drug, making it harder to treat. The fungus forms protective biofilms that shield it from treatment, requiring combination antifungal medications and sometimes surgery to drain the fluid and remove infected tissue for successful recovery.

Epidemiology of Candidemia, Candiduria and Emerging Candidozyma (Candida) auris Across Gulf Cooperative Council Countries and Yemen in the Arabian Peninsula

mycolabadmin

This comprehensive review examines fungal bloodstream and urinary tract infections caused by Candida species across Middle Eastern countries. The study shows that while Candida albicans remains common, dangerous antibiotic-resistant strains like Candidozyma auris are increasingly appearing in hospitals. The research highlights that better diagnostic tools and infection prevention practices are urgently needed in the region to protect patients and reduce deaths from these serious infections.

Global status and trends of invasive pulmonary aspergillosis: A bibliometric study

mycolabadmin

This study analyzes 24 years of research on invasive pulmonary aspergillosis, a serious fungal infection in immunocompromised patients. Using bibliometric tools, researchers mapped out how the field has evolved, identifying leading countries (USA, Germany, China), key experts like David Denning and Thomas Walsh, and shifting research focus from transplant-related infections to COVID-19-associated cases. The analysis shows the field is rapidly growing with increasing emphasis on rapid diagnostic methods and antifungal therapies.

A Review on Aspergillosis in Turkey: As a Main Fungal Disease in Poultry

mycolabadmin

Aspergillosis is a serious fungal disease affecting turkeys, especially young birds, caused by breathing in fungal spores from moldy hay, compost or poorly ventilated housing. The disease causes respiratory problems, can spread to other organs, and can kill 30-50% of affected flocks. Prevention through good ventilation, clean housing and dry feed is more effective than treatment since few antifungal drugs are approved for food animals. Understanding how environmental conditions promote this disease is key to protecting turkey populations.

Targeted long-read sequencing analysis and antifungal susceptibility profiles of Sporothrix schenckii isolates from Thailand

mycolabadmin

This research examined a fungal infection called sporotrichosis found in Thailand, particularly in cats and humans. Scientists used advanced DNA sequencing technology to accurately identify which species of the fungus caused the infections and understand how they are related to each other. They also tested how well common antifungal medications work against these fungi, finding that some strains have become resistant to itraconazole, the main drug used to treat sporotrichosis.

Inappropriate treatment of pulmonary aspergillosis caused by Aspergillus flavus in susceptible pediatric patients: a case series

mycolabadmin

This case series describes three children in Iran who developed serious lung infections caused by a fungal organism called Aspergillus flavus. Tragically, two of the three children died because their infections were diagnosed too late and they did not receive appropriate antifungal medications. The study emphasizes that children with weakened immune systems need quick diagnosis and proper antifungal treatment to survive these dangerous fungal infections.

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.

Candidemia due to Candida lambica in a neutropenic oncology patient: A rare case report

mycolabadmin

A 56-year-old cancer patient developed a serious bloodstream infection caused by a rare yeast called Candida lambica despite taking antifungal medications. Doctors identified the infection using genetic sequencing and found that the organism was sensitive to a different antifungal drug called voriconazole. After switching medications and removing the patient’s central line, the infection cleared up. This case demonstrates the importance of accurately identifying fungal infections and testing which medications work best against them.
