  • Annex REPORT for 2019 UNDER the “HEALTH CARE” PRIORITY of the NATIONAL ROMA INTEGRATION STRATEGY of the REPUBLIC of BULGAR
    Annex REPORT FOR 2019 UNDER THE “HEALTH CARE” PRIORITY of the NATIONAL ROMA INTEGRATION STRATEGY OF THE REPUBLIC OF BULGARIA 2012 - 2020 Operational objective: A national monitoring progress report has been prepared for implementation of Measure 1.1.2. “Performing obstetric and gynaecological examinations with mobile offices in settlements with compact Roma population”. During the period 01.07—20.11.2019, a total of 2,261 prophylactic medical examinations were carried out with the four mobile gynaecological offices to uninsured persons of Roma origin and to persons with difficult access to medical facilities, as 951 women were diagnosed with diseases. The implementation of the activity for each Regional Health Inspectorate is in accordance with an order of the Minister of Health to carry out not less than 500 examinations with each mobile gynaecological office. Financial resources of BGN 12,500 were allocated for each mobile unit, totalling BGN 50,000 for the four units. During the reporting period, the mobile gynecological offices were divided into four areas: Varna (the city of Varna, the village of Kamenar, the town of Ignatievo, the village of Staro Oryahovo, the village of Sindel, the village of Dubravino, the town of Provadia, the town of Devnya, the town of Suvorovo, the village of Chernevo, the town of Valchi Dol); Silistra (Tutrakan Municipality– the town of Tutrakan, the village of Tsar Samuel, the village of Nova Cherna, the village of Staro Selo, the village of Belitsa, the village of Preslavtsi, the village of Tarnovtsi,

CLEMENCON Institut de Botanique Systematique Bätiment de Biologie, Universite de Lausanne CH-1015 Lausanne-Dorigny, Switzerland Introduction Microscopic examination of some hundred European collections of Paxillus (belonging to the section Paxillus) revealed the existence of an uncommon hyphal type characterized by transverse ribs located at the inner surface of the wall. The present paper describes possible development and the occurrence of these and related struc- tures in Paxillus. Material and methods The collections studied are deposited in Leiden (L), Munich (M), Stockholm (S), Kew (K) and Lausanne (LAU) under the names Paxillus filamentosus, P. leptopus, P. rubicundulus (including type specimen) and P. involutus. For ease of reference to the herbarium collections all these names will be used here, despite the fact that the epithets "leptopus" and probably also "rubicundulus" are synonyms of filamentosus. A small fragment of the gills is soaked for 5 to 15 minutes in concentrated ammonia or preferably in a solution called "Kanamoa" (KOH-NaCl buffer 55 ml; glycerol 15 g; ethylene glycol monomethyl ether, Merck 859 25 ml). The KOH-NaCl buffer is prepared by dissolving 3.6 g of KOH and 3.8 g of NaCl in 420 ml of distilled water.

  • Tile Geoglossaceae of Sweden **
    ARKIV FOR· BOTANIK. BAND 30 A. N:o 4. Tile Geoglossaceae of Sweden (with Regard also to the Surrounding CQuntries). By J. A. NANNFELDT. With 5 plates and 6 figures in the text. Communicated June 4th, 1941, by NILS E. SVEDELIUS and ROB. E. FRIES. There are hardly any Discomycetes that have been the subject of so many monographs as the Geoglossaceae. Already in 1875, COOKE (1875 a, 1875 b) published two monographic studies, and some years later he described and illustrated in his Mycographia (COOKE 1879) the majority of the species known at that time. In 1897, MAssEE published a world monograph of the family, though this paper - as so many other publications by the same author - is mainly a compi­ lation. DURA.ND'S monog-raph (1908, with a supplement in 19~1) of the North American species is a model of accuracy and thoroughness, and indispensable also for other parts of the world. This monograph was the base for a pamphlet by LLOYD (1916) on the Geoglossaceae of the world. If we add v. LUYK'S revision (1919) of the Geoglossaceae in the Rijks­ herbarium at Leiden, with all PERSOON'S specimens, SINDEN & FITZPATRICK'S paper (1930) on a new species of T1'ichoglos8ttrli, IMAI'S studies (1934, 1936 a, 1936 b, 1938) on Japanese species of certain genera, his list of the Norwegian Geoglos8aceae (IMA.I 1940), and MAIN'S papers (1936, 19~0) with descriptions of several new American species, the most important contri­ butions of recent date to the taxonomy of the family have been mentioned.

  • 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.

  • Screening for Rapidly Evolving Genes in the Ectomycorrhizal Fungus

Strains with various abilities to form mycorrhizae were analysed by comparative genomic hybridizations using a cDNA micro- array containing 1076 putative unique genes of P. involutus. To screen for genes diverging at an enhanced and presumably non-neutral rate, we implemented a simple rate test using information from both the variations in hybridizations signal and data on sequence diver- gence of the arrayed genes relative to the genome of Coprinus cinereus. C. cinereus is a free- living saprophyte and is the closest evolutionary relative to P. involutus that has been fully sequenced. Approximately 17% of the genes investigated were detected as rapidly diverging within Paxillus. Furthermore, 6% of the genes varied in copy numbers between the analysed strains. Genome rearrangements associated with this variation including dupli- cations and deletions may also play a role in adaptive evolution. The cohort of divergent and duplicated genes showed an over-representation of either orphans, genes whose products are located at membranes, or genes encoding for components of stress/defence reactions.

  • Characterization of Red Alder Ectomycorrhizae: a Preface to Monitoring Belowground Ecological Responses
    516 Characterization of red alder ectomycorrhizae: a preface to monitoring belowground ecological responses STEVEN L. M ILLER AND C. D. Koo Department of Forest Science, Oregon State University, Corvallis, OR 97331, U.S.A. AND R ANDY MOLINA United States Department of Agriculture, Forest Service, Pacific Northwest Research Station, Forestry Sciences Laboratory, 3200 Jefferson Way, Corvallis, OR 97331, U.S.A. Received May 2, 1990 M ILLER, S. L., Koo, C. D., and M OLINA, R. 1991. Characterization of red alder ectomycorrhizae: a preface to monitoring belowground ecological responses. Can. J. Bot. 69: 516-531. Critical ecological research on belowground ecosystems has often been impeded because of the inability to adequately recognize ectomycorrhizal relationships, especially the abundance, diversity, and distribution of the fungus component, and the specificity of particular fungus—host combinations. Red alder, with its high degree of host specificity and paucity of fungal symbionts, provides an ideal model for studying these attributes. Eleven morphologically recognizable types of ecto- mycorrhizae were characterized from field-collected root material, greenhouse soil bioassays, and laboratory syntheses. Most mycobionts were basidiomycetes, as evidenced by abundant clamp connections present in the mantle and extramatrical hyphae. Seven mycobionts identified to species included Alpova diplophloeus, Thelephora terrestris, Lactarius obscuratus, Cortinarius bibulus, Laccaria laccata, Hebeloma crustuliniforme, and Paxillus involutus. Many of the ectomycorrhizae collected in the field appeared to have more than one mycobiont present in the mantle. Root tips could generally be categorized into either flexuous or succulent morphological types. The flexuous types were long, thin, indeterminate in growth, with an acute root apex, and the mantle and Hartig net in longitudinal section were not well formed near the root apex.
