Moldagulova avenue, 34 Abstract With the use of classical identification methods, which imply the identification of fungi by cultural and morphological features, they may not be reliable. With the development of modern molecular methods, it became possible to quickly and accurately determine the species and race of the fungus. The purpose of this work was to study bioecology and refine the species composition of fungi of the genus Aspergillus, Penicillium on seeds of cereal crops. The article presents materials of scientific research on morphological and molecular genetic peculiarities of storage fungi, affecting seeds of grain crops. Particular attention is paid to the fungi that develop in the stored grain. The seeds of cereals (Triticum aestivum L., Avena sativa L., Hordeum vulgare L., Zea mays L., Oryza sativa L., Sorghum vulgare Pers., Panicum miliaceum L.) were collected from the granaries of five districts (Talgar, Iliysky, Karasai, Zhambul, Panfilov) of the Almaty region. The pathogens of diseases of fungal etiology were found from the genera Penicillium, Aspergillus influencing the safety, quality and safety of the grain. -
The Phylogeny of Plant and Animal Pathogens in the Ascomycota
Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus. -

In all the four dead patients, the cause of death was immunocompetent individuals. These are slow, progressive, respiratory failure and all patients were previously treated for and not involved in angio-invasion compared with invasive pulmonary tuberculosis. pulmonary aspergillosis. The predisposing factors being Conclusion When a patient with pre-existing lung disease compromised lung parenchyma owing to chronic obstructive like chronic obstructive pulmonary disease or old tuberculosis pulmonary disease and previous pulmonary tuberculosis. As cavity presents with cough with expectoration, not many studies have been conducted in CPA with respect to breathlessness, and hemoptysis, CPA should be considered clinical and laboratory profile, the study was undertaken to as the first differential diagnosis. examine the profile in our population.

Lists of Names in Aspergillus and Teleomorphs As Proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (Doi: 10.3852/14-0
Lists of names in Aspergillus and teleomorphs as proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (doi: 10.3852/14-060), based on retypification of Aspergillus with A. niger as type species John I. Pitt and John W. Taylor, CSIRO Food and Nutrition, North Ryde, NSW 2113, Australia and Dept of Plant and Microbial Biology, University of California, Berkeley, CA 94720-3102, USA Preamble The lists below set out the nomenclature of Aspergillus and its teleomorphs as they would become on acceptance of a proposal published by Pitt and Taylor (2014) to change the type species of Aspergillus from A. glaucus to A. niger. The central points of the proposal by Pitt and Taylor (2014) are that retypification of Aspergillus on A. niger will make the classification of fungi with Aspergillus anamorphs: i) reflect the great phenotypic diversity in sexual morphology, physiology and ecology of the clades whose species have Aspergillus anamorphs; ii) respect the phylogenetic relationship of these clades to each other and to Penicillium; and iii) preserve the name Aspergillus for the clade that contains the greatest number of economically important species. Specifically, of the 11 teleomorph genera associated with Aspergillus anamorphs, the proposal of Pitt and Taylor (2014) maintains the three major teleomorph genera – Eurotium, Neosartorya and Emericella – together with Chaetosartorya, Hemicarpenteles, Sclerocleista and Warcupiella. Aspergillus is maintained for the important species used industrially and for manufacture of fermented foods, together with all species producing major mycotoxins. The teleomorph genera Fennellia, Petromyces, Neocarpenteles and Neopetromyces are synonymised with Aspergillus. The lists below are based on the List of “Names in Current Use” developed by Pitt and Samson (1993) and those listed in MycoBank (www.MycoBank.org), plus extensive scrutiny of papers publishing new species of Aspergillus and associated teleomorph genera as collected in Index of Fungi (1992-2104).
