Cerebral mucormycosis in man is an unusual, generally fatal, fungus infection, occurring chiefly in patients with diabetic acidosis. Clinically, the infection is characterized by unilateral ophthalmoplegia and meningoencephalitis. At autopsy the orbital tissues, meninges, and brain are invaded by fungus. Involvement of the paranasal sinuses has been noted in a few instances. In the past the fun...

FROM THE PRECEDING I DERIVE THE FOLLOWING CONCLUSIONS: 1. The disease which formerly has been described as a form of protozoon-infection is due to an infection with a pathogenic fungus. 2. The infection may primarily be either a cutaneous or a pulmonary one. 3. The lesions produced by this fungus fall under the general head of infectious granulomata and consist partly in nodules resembling alto...

Mucormycosis or black fungus is usually a rare but life-threatening infection resulting from commonly distributed fungi belongingto the Mucorale orders. The disease was previously known as zygomycosis, since Rhizopus species, such as Rhizopus arrhizus, Rhizopus microsporus, and Rhizopus oryza were more isolated from infected patients than Mucor (Chegini et al., 2020, Spellberg, 2017)

It was first described by B.R.Schenck in the Bulletin of the Johns Hopkins Hospital in 1898. [1] Subsequently, Hektoen and Perkins named this pathogenic fungus Sporothrix schenckii in 1900. [1] Infection usually presents as ulcer...

In normal rabbits subcutaneous granulomata produced by the injection of a spore suspension of Rhizopus oryzae remained confined to the site of inoculation, showed no fungus proliferation, no longer yielded the agent on culture 10 weeks after inoculation, and eventually healed. Similar well established granulomata in rabbits with acute alloxan diabetes induced 8, 10, and 15 days after injection ...

A filamentous fungus that caused a fatal systemic infection in a dog has been identified as the new species Sagenomella chlamydospora. When the case was initially reported, the fungus was identified as Paecilomyces sp. This study emphasizes how difficult can be the identification of the causative agent of an infection when an uncommon microorganism is involved. This is the first time that this ...

Rice (Oryza sativa L.) is a major staple food crop for half of the world’s population. The International Rice Research Institute, Philippines, estimates that in order to feed the growing global population, rice production must increase by another one-third by the year 2020. Magnaporthe grisea (anamorph, Pyricularia oryzae) causes rice blast disease (Figure 1) and is the most destructive pathoge...

The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) is sensitive to high temperature. Hence, exposing amphibians to high temperature may be a method to clear Bd infection. However, the effect of exposure to elevated temperature has never been tested in larval stages or temperate species.We experimentally exposed tadpoles of the toad Alytes obstetricans to low, medium and high tempe...

To cause rice blast disease, the fungus Magnaporthe oryzae elaborates specialized infection structures called appressoria, which use enormous turgor to rupture the tough outer cuticle of a rice leaf. Here, we report the generation of a set of 22 isogenic M. oryzae mutants each differing by a single component of the predicted autophagic machinery of the fungus. Analysis of this set of targeted d...

Calonectria crotalariae enhanced root penetration of Lee 74 (susceptible) and Centennial (resistant) soybeans by juveniles of race 3 of Heterodera glycines. Numbers of cysts in and on the roots of Lee 74 increased during the first 30 days in the presence of the fungus. Percentage of root infection by the fungus increased at 40 days in Lee 74 in the presence of the nematode. Numbers of cysts in ...
