Fungal keratitis complicating the diagnosis of Acanthamoeba keratitis

A 42-year-old farmer presented with a severe eye infection that was initially misdiagnosed as a viral infection caused by herpes simplex virus. When antiviral treatment failed, doctors discovered the patient had a fungal infection caused by Fusarium. However, advanced testing revealed she actually had a dual infection with both the fungus and a microscopic parasite called Acanthamoeba. The patient required corneal transplant surgery and combination therapy with multiple medications to control the infection and preserve vision.

Various types of mycorrhizal fungi sequences detected in single intracellular vesicles

Researchers discovered that single fatty droplet-like structures inside plant roots can contain genetic material from multiple types of fungi, both Glomeromycotina and Mucoromycotina. They developed new molecular tools to detect and identify these fungi without bias. This finding suggests fungi may live together more intimately than previously thought, which could help us better understand how plants get nutrients from fungal partners in soil.

Nosocomial Diarrhea Distribution by Cryptosporidium in Isfahan

Researchers tested 217 patients who developed diarrhea in a hospital in Isfahan, Iran to see if a parasite called Cryptosporidium was responsible. Using advanced DNA testing, they found the parasite in only 2 out of 217 patients (less than 1%). This suggests that while this parasite can spread in hospitals, it is not a major cause of diarrhea in this particular hospital, which likely has good hygiene practices.
