Microsclerotia formation of the biocontrol fungus Cordyceps javanica IF-1106 and evaluation of its stress tolerance and pathogenicity

mycolabadmin

Researchers studied a fungus called Cordyceps javanica that can be used to control harmful soil nematodes that damage crop roots. The fungus produces special dormant structures called microsclerotia that can survive extreme heat and UV radiation for extended periods. These microsclerotia showed excellent effectiveness at controlling root-knot nematodes on cucumber plants while also promoting plant growth, making them a promising natural alternative to chemical pesticides.

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

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.
