Opis:: Tolerance of several strains of the P-, S-, and F- intersterility groups of Heterobasidion annosum to low pH and high concentration of aluminium ions was studied on malt extract agar. There were marked intraspecific, but not intergroup, variations in tolerance to both factors. Some strains were relatively tolerant or sensitive to low pH and aluminium, while the others were tolerant to low pH but sensitive to Al. There was no relationship between tolerance of the strains to low pH and their tolerance to aluminium stress.

Opis:: Autochthonous fungi are potential successful agents in the process of bioremediation through their efficient adaptation to pollutant toxicity and competition with other microorganisms that are present in the leachate treatment plant. The leachate from municipal waste landfills was an important source of fungi. Even though some of these fungi have the potential to be human pathogens, such strains wh en used in biolo gical treatment approaches may serve as a possible tool for integrating the leachate bioremediation process because of the extracellular enzymes produced by fungal strains. In this study, the leachate sample was tested with regard to four parameters, including total dissolved solids (TDS), electrical conductivity (EC), pH, and the decolorization of the leachate sample by a number of indigenous species of fungi, which were observed by use of the culture techniques. The scanning electron microscope coupled with energy dispersive x-ray analysis, UV-spectrum, and reflected and transmitted polarizing light microscope were used in the research project to o bserve and assess the obtained data from the experimental work. The results indicated the various levels of efficiency of the isolated fungal strains in eliminating color, lowering TDS, EC, and pH through their geoactivities potential in metal biosorption and immobilization by biomineralization of new minerals in the growth environment and eventually reducing the metal bioavailability and toxicity.

Opis:: Mass spectrometry (MS) is a universal technique with a wide range of applications, including proteomic studies of different organisms, particularly the characterization and sequencing of proteins isolated from specific cellular compartments. It is used for the identification of elements exposed on the cell surface of microbial pathogens, which are involved in the initial contact with the human host, and then in the further development of infection. Given the increasing frequency of invasive fungal infections caused by pathogenic yeast from the genus Candida, especially among patients with severe immunological impairments, it appears advisable to study the diversity of cell wall proteins that arise during subsequent stages of infection and that are responsible for several important phenomena correlated with pathogenesis. This study employed a liquid chromatograph-coupled mass spectrometer equipped with an electrospray ionization source (ESI), and an ion trap analyser. For tandem mass spectrometry, two approaches for fragmentation of ions - collision-induced dissociation (CID) and electron transfer dissociation (ETD) - were used to analyse the mixtures of peptides generated after tryptic digestion of fungal cell wall proteins (i.e. the “bottom-up” approach). Several surface proteins from Candida spp. were identified which could be potential drug targets and candidates for vaccine development.

Opis:: Grain samples of two maize hybrids, medium early (ZP434) and late maturity (ZP704), collected during harvest in 2008 were investigated for contamination by fungi. Grains were plated on agar media and grown fungi were identified by morphological macroscopic and microscopic characteristics on potato-dextrose agar (PDA) and synthetic nutrient agar (SNA). Species of the genus Fusarium were the most common in both hybrids, and their presence amounted to 33.89% (ZP434) and 42.00% (ZP704). Other fungi of genera, Acremonium, Alternaria, Aspergillus, Chaetomium, Cladosporium, Nigrospora, Penicillium, Rhizopus and Trichotecium, were isolated from 0 to 41.00%. Four species belonging to the genus Fusarium were identified, of which the species F. verticillioides was the most common with 28.63% in ZP434 and 30.50% in ZP704 hybrids. The presence of F. graminearum, F. proliferatum and F. subglutinans ranged from 3.00% (ZP704) to .00% (ZP434), 0.13% (ZP434) to 7.00% (ZP704) and 0.13% (ZP434) to 7.00% (ZP704), respectively. Generally, the incidence of every particular fungus was higher in the late maize hybrid with a higher moisture content than in the medium-early hybrid with a lower moisture content.

Opis:: The frequency of severe systemic fungal diseases has increased in the last few decades. The clinical use of antibacterial drugs, immunosuppressive agents after organ transplantation, cancer chemotherapy, and advances in surgery are associated with increasing risk of fungal infections. Opportunistic pathogens from the genera Candida and Aspergillus as well as pathogenic fungi from the genus Cryptococcus can invade human organism and may lead to mucosal and skin infections or to deep-seated mycoses of almost all inner organs, especially in immunocompromised patients. Nowadays, there are some effective antifungal agents, but, unfortunately, some of the pathogenic species show increasing resistance. The identification of fungal virulence factors and recognition of mechanisms of pathogenesis may lead to development of new efficient antifungal therapies. This review is focused on major virulence factors of the most common fungal pathogens of humans: Candida albicans, Aspergillus fumigatus and Cryptococcus neoformans. The adherence to host cells and tissues, secretion of hydrolytic enzymes, phenotypic switching and morphological dimorphism contribute to C. albicans virulence. The ability to grow at 37°C, capsule synthesis and melanin formation are important virulence factors of C. neoformans. The putative virulence factors of A. fumigatus include production of pigments, adhesion molecules present on the cell surface and secretion of hydrolytic enzymes and toxins.

Opis:: The study was conducted in 2014 at the West Pomeranian University of Technology in Szczecin. Its aim was to identify the taxa of microscopic fungi present on selected herbal plants and to propose methods of their elimination. Research material included leaves and stems of affected plants. The material was collected at the end of the growing season (in September). The study identified 11 taxa belonging to two types of fungi: Ascomycetes and Basidiomycetes. Most identified taxa (98.2%) belonged to Ascomycetes. Three species rarely found in Poland were recognized: Ascochyta levistici, Septoria melissae and Phragmidium sanguisorbae. Diseases of herbal plants should preferably be eliminated by using biological methods and appropriate agrotechnical treatments.

Opis:: Objectives: Yeasts may become potential human and animal pathogens, particularly for individuals with a depressed immune system. Their presence in the environment, especially in soil, may favour their spread into human ontocenoses. Materials and Methods: Eighty-four soil samples obtained from 21 children's recreational sites in Łódź in autumn 2010 and spring 2011 were evaluated. The yeasts were isolated by classical microbiological methods and identified on the basis of morphological and biochemical features. Results: The fungi were found in 73.8% and in 69.0% of the examined samples collected in autumn and spring, respectively. Among 97 isolates of yeasts, the species potentially pathogenic to humans and animals were Candida colliculosa, C. guilliermondii, C. humicola, C. inconspicua, C. lambica, C. lusitaniae, C. pelliculosa, C. tropicalis, Cryptococcus albidus, C. laurentii, C. neoformans, C. terreus, Kloeckera japonica, Geotrichum candidum, G. penicillatum, Rhodotorula mucilaginosa, R. glutinis, Saccharomyces cerevisiae, Sporobolomyces salmonicolor and Trichosporon cutaneum. The most frequently isolated fungi included the genus Cryptococcus (38 isolates) and two species: Rhodotorula glutinis (15), Trichosporon cutaneum (14). C. neoformans, an etiological factor of cryptococcal meningitis, was present in the sandpits of 3 kindergartens. The Candida species were identified from park playgrounds and school sports fields mainly in autumn 2010 (14 isolates), in spring 2011 - only 1 isolate. The concentration of fungal species in particular samples varied considerably, but in the majority of samples, fungi were present at concentration of up to 1×10² CFU/1 g of soil. Conclusions: Yeasts were present in the soil of parks, schools and kindergarten recreational areas; the fact may pose a health risk to humans, especially to children, and this type of biological pollution should be regarded as a potential public health concern.
