Primary non-gonococcal urethritis of venereal origin is usually abacterial. This is also the case when the disease follows rectal coitus (Harkness, 1950). When organisms are present in the secretions in untreated cases the disease is more likely to have been caused by infections descending from a urethral stricture, the prostate, or lesions of the upper urinary tract. It can also be caused mech...

The ascomycete Sclerotinia sclerotiorum is a plant pathogen with a very broad host range. In order to identify and characterize genes involved in S. sclerotiorum infection of Brassica napus (canola), expressed sequence tags (ESTs) were examined from libraries prepared from three tissues: complex appressorium (infection cushions), mycelia grown on agar and lesions formed on leaves of B. napus. A...

Saprophytic infestation with Aspergillus was observed in pathologic specimens of primary squamous cell lung carcinoma. In one case, the fungus grew in cystic scarred parenchyma and bronchi distal to an obstructing carcinoma of a segment bronchus. In the other, fungi colonized the inner surface of a peripheral cavitary carcinoma. Neither patient had roentgenographic evidence of aspergilloma and ...

Aspergillosis is an infection caused by saprophytic fungi of the genus Aspergillus, which typically occurs in immunosuppressed individuals, but has also been reported in immunocompetent patients. The main routes of entry are the respiratory tract, skin, cornea, and ear, and the infection may be localized or disseminated by contiguity or vascular invasion. We report a severe case of rhinosinusit...

Background: There is evidence to demonstrate an association between fungal sensitization and asthma. Several studies have shown that saprophytic fungi such as Alternaria, Penicillium and Aspergillus species are the most prevalent fungal allergens worldwide. The main purpose of this study was to compare Alternaria alternata, Penicillium ci...

Background: Chronic otitis media (CSOM) is a notorious infection prevalent mostly in developing countries due to indiscriminate uses of local steroid and antibiotics in the ear either alone or combination. Humidity also plays a major contributing factor in the etiology of otitis media. Objective: To know the prevalence of fungal infection in chronic suppurative otitis media. Method: The study w...

Aspergillus, a genus of spore forming fungi found worldwide, affects the respiratory tract in many ways [1, 2]. The spores of this ubiquitous mould are dispersed by wind in the atmosphere and inhalation is the primary route of access in almost all forms of aspergillosis. The spectrum of Aspergillus-associated respiratory disorders comprises three well defined clinical categories (table 1): alle...

Although the total growth of both zoopathogenic and saprophytic fungi on cycloheximide media was consistently less than that on the control without the antibiotic, a progressive increase in the growth rate of these organisms occurred during exposure to the drug. The extent of this change depended upon the concentration of cycloheximide, the species and strain of the test organism, and the durat...

Plants exist in a world filled with microorganism. They continue to grow in the same location throughout the growing season or for many years, as in the case of perennial plants. Their surfaces are constantly exposed to bacteria, fungi, nematodes, and possibly parasitic plants. They may be inoculated with viruses during feeding by insects or by other vectors. Plant pathogens have made many adap...

Phosphate minerals hydroxylapatite, fl uorapatite and crandallite were identifi ed in nodules within phosphorites from Ervenik, Croatia. The minerals were identifi ed using optical microscopy, XRD, SEM and EDS analyses. The presence of fungi was recognized only in association with phosphate-rich phases. Fungal activity resulted in the dissolution of apatite, producing hollow crystals, particula...
