Emmonsia crescens, a dimorphic fungus of the order Onygenales, is primarily a pathogen of lower animals and rarely humans. Inhaled conidia of E. crescens fail to germinate in the lungs, and instead simply enlarge in lung tissue to become giant adiaspores. We present here the case of fatal Emmonsia crescens infection in a wild-caught British water vole (Arvicola terrestris). Histopathological ex...

Lipoxygenase (LOX) and lipid hydroperoxide-decomposing activity (LHDA) markedly increased in the fifth leaves of rice (Oryza sativa cv Aichiasahi) after infection with the rice blast fungus, Magnaporthe grisea. The increases in the enzyme activities were significantly higher in response to infection with an incompatible strain (race 131) compared with infection with a compatible strain (race 00...

The rice blast fungus, Magnaporthe oryzae, is a model plant pathogenic fungus and is a severe threat to global rice production. Over the past two decades, it has been found that the peroxisomes play indispensable roles during M. oryzae infection. Given the importance of the peroxisomes for virulence, we review recent advances of the peroxisomes roles during M. oryzae infection processes. We fir...

To improve the biological control of white mistletoe (European mistletoe) additional detailed information on Botryosphaeria visci infection, its basic nutritional requirements, growth, and in vitro growth characteristics is needed. The objectives this study were to isolate identify fungus B. associated with Viscum аlbum from Sorbus aucuparia, provide introduction different media, test pathogeni...

Allescheria boydii and its imperfect state, Monosporium apiospermum, were studied to determine whether asexual or sexual strains might exhibit different pathogenic potentials for mice. Six different strains of the fungus were inoculated into mice by the intravenous, intracerebral, intraperitoneal, and intranasal routes. Cortisone-treated mice regularly developed infections after inoculation by ...

Fungus balls are a chronic and non-invasive fungal infection. Despite being relatively common in the paranasal sinuses, they rare nasal cavity. The etiology of fungus cavity is unknown. generally develop slowly asymptomatically. When symptomatic, can cause symptoms similar to those sinusitis or intranasal masses, such as obstruction, postnasal discharge, head face pain, smell perception disorde...

Rice blast is caused by the fungus Magnaporthe grisea, which elaborates specialized infection cells called appressoria to penetrate the tough outer cuticle of the rice plant Oryza sativa. We found that the formation of an appressorium required, sequentially, the completion of mitosis, nuclear migration, and death of the conidium (fungal spore) from which the infection originated. Genetic interv...

Histology: The brain, meninges, spleen and kidneys showed the fungus, which appeared as small spheres reproducing by budding. The lesions in the brain were meningeal and perivascular in the basal ganglia. The lesions in the brain and spleen had a minimal tissue reaction. In the liver and kidneys there were miliary collections of histiocytic cells containing the fungus. The firm nodule in the lu...

Development of aspergilloma is common in cases with a fungus ball-like shadow in cavities due to old tuberculosis. Some reports have shown that blood clots tend to appear as a fungus ball-like shadow. A 71-year-old man with a history of pulmonary tuberculosis presented with a fungus ball-like shadow in an old cavity and hemoptysis. There was no evidence of aspergillus infection on various exami...
