Lettuce downy mildew, caused by the oomycete Bremia lactucae Regel, is a major threat to lettuce production worldwide. Lettuce downy mildew is a polycyclic disease driven by airborne spores. A weather-based dynamic simulation model for B. lactucae airborne spores was developed to simulate the aerobiological characteristics of the pathogen. The model was built using the STELLA platform by follow...

VARIABILITY IN THE PRODUCTION OF FUNGAL SPORES AND IN THE MEASUREMENT OF SPORE YIELDS WAS INVESTIGATED IN FOUR SPECIES OF FUNGI: Colletotrichum gloeosporioides, Colletotrichum coccodes, Colletotrichum phomoides, and Acremonium strictum. When the fungi were grown on solid medium in microplates and spore yields were measured by counting the subsamples with a hemacytometer, the variability among h...

Microfluidic continuous flow filtration methods have the potential for very high size resolution using minimum feature sizes that are larger than the separation size, thereby circumventing the problem of clogging. Branch flow filtration is particularly promising because it has an unlimited dynamic range (ratio of largest passable particle to the smallest separated particle) but suffers from ver...

The COVID-19 infection caused by the novel SARS-CoV-2 may be associated with a wide range of disease patterns, ranging from mild to life-threatening pneumonia. Mucormycosis is an emerging angioinvasive fungal ubiquitous filamentous fungi Mucorales order class Zygomycetes. prevalence mucormycosis in India about 80 times developed countries. invade deep tissues via inhalation airborne spores, per...

Post-remedial collection of 2,193 fungi samples were evaluated as a component of a three (3) tiered clearance criteria for mold remediations projects. Criterion #1 was the visual evaluation of remediated areas for the absence of fungal growth. Criterion #2 was the visual evaluation of surfaces in remediated areas for the absence of visible debris. Criterion #3 involved the evaluation of total f...

BACKGROUND Alternaria is the most important fungal species belonging to the class Deuteromycetes which causes allergic respiratory diseases. The fungus pattern often shows a pronounced seasonal periodicity and with fluctuations related to meteorological conditions. In this study, we aimed to investigate the effect of outdoor Alternaria spore concentrations on monthly lung function tests, sympto...

Fungi are ubiquitous and their spores found in the air outside within built environment. We investigated fungal species present a teaching laboratory at Shepherd University. Airborne fungi were captured passively three sites on two different culture media. Viable isolated to pure then identified by DNA barcode using internal transcribed spacer region of ribosomal DNA. Twenty-four isolates order...

To gain further insight into the role of the plant genome in arbuscular mycorrhiza (AM) establishment, we investigated whether symbiosis-related plant genes affect fungal gene expression in germinating spores and at the appressoria stage of root interactions. Glomus intraradices genes were identified in expressed sequence tag libraries of mycorrhizal Medicago truncatula roots by in silico expre...
