CONTEXT: Paracoccidioidomycosis is a systemic form of mycosis that spreads hematogenously, secondarily to reactivation of lung infection or infection at another site or to new exposure to the causative agent. Few cases of bone involvement have been reported in the literature and involvement of the spine is extremely rare. CASE REPORT: We describe a case of a 68-year-old male patient with spon...

Phaeohyphomycosis consists of a heterogeneous group of fungal infections caused by more than 80 genera and species. Subcutaneous infection usually follows traumatic implantation of a fungus by a wooden splinter that the fungus inh abits as a saprophyte. The growth of the fungus forms verrucous plaques or a painless subcutaneous abscess. We report a subcutaneous cyst (phaeomycotic cyst) in the l...

This book is an attempt to prove that there are certain conditions of enlarged spleen due to mycotic fungi. The evidence put forward by the writer is extremely weak, although he states that he has cultivated a Nocardia fungus which he has named Nocardia splenica. In support of his views, he quotes Professor Nanta's work on the same subject, but it is certain that Nanta's cases were due to an As...

Concha bullosa is the pneumatization of the concha and is one of the most common variations of the sinonasal anatomy. The histopathological changes caused by the infections which arise from the impaired aeration of conchal cavity are frequently found. Fungus ball of the nasal cavity is an extremely rare, fungal infection with only three cases reported previously. In this paper, we present the f...

We describe a case of subcutaneous infection as a result of traumatic implantation caused by the fungus Lasiodiplodia theobromae. It was isolated in multiple swabs from the foot of an active healthy male. The fungus was identified by traditional mycology culture methods though this was slow with much time required for sporulation on only one of the agars used. Identification was confirmed by DN...

Tinea is a dermatophytid infection caused by fungus. Corporis type of glabrous dermatophytosis that occurs on skin except palms, soles, groins. A 24-year-old female reported having corporis for the last 2 months. complete case history was taken and basis individualization, graphite given.

We investigated the cellular responses of stem tissues of mature Scots pine (Pinus sylvestris L.) trees to inoculations with two fungal pathogens. The bark beetle vectored fungus, Leptographium wingfieldii Morelet, induced longer lesions in the bark, stronger swelling of polyphenolic parenchyma cells, more polyphenol accumulation and increased ray parenchyma activity compared with the root rot ...

FgABC1 (FGSG_04580) is predicted to encode a pleiotropic drug resistance class ABC transporter in Fusarium graminearum, a globally important pathogen of wheat. Deletion mutants of FgABC1 showed reduced virulence towards wheat in crown and root infection assays but were unaltered in infectivity on barley. Expression of FgABC1 during head blight and crown rot disease increases during the necrotro...

To understand key processes governing defense mechanisms in poplar (Populus spp.) upon infection with the rust fungus Melampsora larici-populina, we used combined histological and molecular techniques to describe the infection of Populus trichocarpa x Populus deltoides 'Beaupré' leaves by compatible and incompatible fungal strains. Striking differences in host-tissue infection were observed aft...
