Fungal Species: Rhizopus spp.

Clinical profiling, antifungal drug susceptibility, and biofilm formation ability in pulmonary mucormycosis

This study examined 26 patients with a serious lung fungal infection called mucormycosis in a Beijing hospital. Most patients were older with health problems like diabetes and high blood pressure, and sadly about 4 in 10 died. Interestingly, most patients had other infections (viral or fungal) before developing mucormycosis. The researchers tested which antifungal drugs worked best against the fungus, finding that amphotericin B was most effective, though it can damage kidneys. They also discovered that most of the fungal strains could form protective biofilm structures, making treatment more difficult.

Invasive Rhinocerebral Mucormycosis Is a Rare Complication in Systemic Juvenile Idiopathic Arthritis Patient

A 5-year-old girl with a serious joint disease called systemic juvenile idiopathic arthritis developed a dangerous fungal infection in her nasal cavity and brain area. The fungal infection, caused by a mold organism called Lichtheimia, occurred because her immune system was severely weakened by medications used to treat her arthritis. Doctors treated the infection with antifungal drugs and surgery, and the patient eventually recovered by switching to a different arthritis medication. This case highlights how the strong medications needed to control some childhood arthritis can unexpectedly cause serious fungal infections.
