Disseminated sporotrichosis caused by Sporothrix brasiliensis with testicular involvement

mycolabadmin

A 35-year-old homeless man with HIV developed a serious fungal infection caused by Sporothrix brasiliensis that spread throughout his body, including to his brain and testicles. A testicle lump was initially thought to be cancer and surgically removed, but it was actually a fungal infection. This is only the fifth case ever reported of this fungus infecting testicles. The patient was successfully treated with antifungal medications and remains healthy one year later.

Dermatophytosis in a Chilean fox: first case of Nannizzia gypsea in Lycalopex griseus and the need for a one health approach

mycolabadmin

A young wild Chilean fox was found with a skin infection caused by a fungus called Nannizzia gypsea, which lives in soil and can infect animals and humans. This is the first time this fungus has been documented in foxes anywhere. Doctors treated the fox with an antifungal cream and it recovered completely. The case highlights how increasing urbanization and contact between domestic pets, wild animals, and humans can spread fungal diseases, emphasizing the need for a coordinated public health approach.

Isolation and identification of Fusarium species from the water systems of ICUs and transplant wards of hospitals and determination of the in vitro susceptibilities of isolates to conventional antifungals

mycolabadmin

Researchers found dangerous Fusarium fungal species in water systems of hospital ICU wards in Tehran, Iran. These fungi can spread through water fixtures and pose serious risks to patients with weak immune systems. Testing showed that certain antifungal drugs like posaconazole and voriconazole worked well against these fungi, but other drugs were less effective. The study emphasizes the importance of better water management and safety measures in hospitals to protect vulnerable patients.

A rare case of white piedra caused by Candida orthopsilosis

mycolabadmin

A young girl developed small knots on her scalp hair caused by a yeast fungus called Candida orthopsilosis. This is extremely rare, as white piedra is typically caused by different fungi. Doctors identified the fungus using DNA testing and treated it successfully with antifungal creams and shampoo. This case shows that doctors should not dismiss Candida growth as contamination when found on hair.

Epidemiology and outcomes of Candida-associated osteoarticular infections: A multicentre retrospective study from Turkey

mycolabadmin

This study examined 73 patients in Turkey who developed bone and joint infections caused by Candida fungi over ten years. The researchers found that diabetes was very common among patients and made recovery harder, while surgery to clean out infected tissue significantly improved outcomes. Importantly, they discovered resistance to common antifungal medications was higher in certain Candida species compared to others.

Refractory fungal infection: Three case reports highlighting good practice

mycolabadmin

This case series examines three patients with serious fungal infections that did not respond well to standard antifungal treatments. The cases demonstrate how fungi can develop resistance to common antifungal drugs like azoles, making infections harder to treat. The authors emphasize that accurate identification of the fungus, testing its sensitivity to drugs, monitoring drug levels in the blood, and careful use of antifungal medications are essential for successfully treating these difficult infections.

Two Cases of Curvularia geniculata Keratitis Successfully Treated with Natamycin-Based Therapy

mycolabadmin

This report describes two patients who developed rare fungal eye infections caused by Curvularia geniculata after eye injuries. Both patients were successfully treated with antifungal eye drops, particularly natamycin. Molecular testing confirmed the specific fungus causing the infection. Both patients recovered well with excellent vision restoration, demonstrating that proper diagnosis and targeted antifungal treatment can effectively manage this rare condition.

Overexpression of efflux pump and biofilm associated genes in itraconazole resistant Candida albicans isolates causing onychomycosis

mycolabadmin

Nail fungal infections caused by Candida albicans can be difficult to treat when the fungus becomes resistant to common antifungal medications like itraconazole. Researchers found that resistant strains have overactive genes that pump the drug out of fungal cells and genes that help the fungus form protective biofilm structures. Understanding these resistance mechanisms could lead to better combination treatments that block these protective strategies.

Prevalence of fungi and their antifungal and disinfectant resistance in hospital environments: insights into combating nosocomial mycoses

mycolabadmin

This study examined fungal contamination in hospital intensive care units, finding that Aspergillus and other mold species are commonly present in air and ventilation systems. Importantly, many of these fungi have developed resistance to antifungal medications and hospital disinfectants, making them harder to treat and control. The researchers discovered that the same resistant fungi found in hospitals are similar to those infecting patients, suggesting that hospital environments may be spreading these dangerous infections.

Neosartorya udagawae pulmonary infection requiring a surgical treatment in a paediatric haematopoietic progenitor cell recipient

mycolabadmin

A three-year-old boy with leukemia received a bone marrow transplant and developed a serious fungal lung infection caused by Neosartorya udagawae, a rare fungal pathogen. Despite receiving multiple antifungal medications at appropriate doses, the infection continued to worsen and spread in his lungs. Doctors ultimately had to surgically remove the infected portion of his lung (left upper lobe) to successfully treat the infection, and the child recovered completely without recurrence after three years of follow-up.
