Fungal communities in Florida salt marsh mosquito midguts vary between species and over time but have low structure

mycolabadmin

Researchers studied the fungi living in the guts of three types of Florida salt marsh mosquitoes. They found that all mosquitoes carried high amounts of a common environmental yeast called Rhodotorula lamellibrachiae. The type of mosquito species mattered more than the time of year for determining which fungi were present. Unlike bacterial communities in mosquitoes, the fungal communities appeared to assemble somewhat randomly rather than following organized patterns.

Molecular evidence of Enterocytozoon bieneusi in arid urban landscapes of shiraz cockroaches (Blattodea), Southwest Iran: Implications for urban public health surveillance

mycolabadmin

Researchers in Shiraz, Iran found that cockroaches can carry Enterocytozoon bieneusi, a dangerous fungal parasite that causes severe diarrhea in people with weak immune systems. The study collected and tested 378 cockroaches from hospitals and public areas, discovering three positive cases. While the arid climate of Shiraz appears to limit how well these pathogens survive compared to tropical regions, the presence of parasites in hospital cockroaches poses real health risks, especially for vulnerable patients. Better pest control and sanitation in hospitals are essential to prevent spread.
