Aspergillus in Italian Pistachios: Characterization and Detection of Major Aflatoxigenic Species With a Loop-Mediated Isothermal Amplification Assay

mycolabadmin

Researchers studied pistachio nuts from Italy and found dangerous mold species that produce aflatoxins, harmful toxins that can cause serious health problems. They developed a quick and reliable test using molecular biology techniques to detect these molds in pistachios, even at very low levels of contamination. The test uses specially treated dried primers that remain stable for over a month, making it practical for food safety monitoring in warehouses and markets around the world.

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.

A Review on Aspergillosis in Turkey: As a Main Fungal Disease in Poultry

mycolabadmin

Aspergillosis is a serious fungal disease affecting turkeys, especially young birds, caused by breathing in fungal spores from moldy hay, compost or poorly ventilated housing. The disease causes respiratory problems, can spread to other organs, and can kill 30-50% of affected flocks. Prevention through good ventilation, clean housing and dry feed is more effective than treatment since few antifungal drugs are approved for food animals. Understanding how environmental conditions promote this disease is key to protecting turkey populations.

A new molecular seed assay to predict Ustilago nuda field infection levels

mycolabadmin

Scientists developed a new DNA-based test to detect a fungus that infects barley seeds and causes crop disease. This test is faster and more accurate than the current method of manually inspecting seeds under a microscope. By using this new test, farmers can better decide which seeds need treatment, reducing unnecessary use of pesticides while still preventing disease outbreaks in their fields.

Mapping Histoplasma spp. in bats and cave ecosystems: evidence from midwestern Brazil

mycolabadmin

Researchers found that caves in Brazil harbor a dangerous fungus called Histoplasma that can cause a serious lung disease in humans. The study detected the fungus in soil samples from several caves and in multiple bat species living in those caves. The findings show which caves are most dangerous and emphasize the need for warning signs and protective measures for cave visitors and workers in the region.

Newly Designed Fluorescence In Situ Hybridization Probes Reveal Previously Unknown Endophytic Abilities of Tuber magnatum in Herbaceous Plants

mycolabadmin

Scientists discovered that Italian white truffles (Tuber magnatum) can live inside the roots of common herbaceous plants like sedges, not just the oak and poplar trees where they are typically found. Using special fluorescent probes and advanced microscopy, researchers confirmed the presence of active truffle threads inside these plants, particularly in spring. This discovery challenges our understanding of how truffles interact with their environment and may explain why truffle cultivation has been difficult, suggesting they employ more diverse survival strategies than previously thought.
