Cedric Blötz II DANKSAGUNG Lieber Jörg, gute 20.000 km haben wir mal mehr mal weniger stressfrei bereist. Unglaublich, wie viel ich dank dir und der Arbeit reisen konnte. Ich bin dir für all die Möglichkeiten und Freiheiten, die du mir gegeben hast wirklich dankbar. Schon als Bachelorstudent und auch im Master hatte ich das Gefühl, dass du ein Professor/ Doktorvater bist, dem seine Studenten und Doktoranden und auch ihre Themen wichtig sind. Ich find es toll, dass ich sogut wie immer zu dir konnte, um mir wissenschaftlichen, organisatorischen oder persönlichen Rat zu holen. Darüber hinaus ist es großartig, einen Chef zu haben, mit dem man bei Bier und Sektflöten immer Spaß haben kann. Christina, ohne dich wäre ich im Labor-“handwerklichen“ wie auch in meiner Ideenvielfalt was Versuche betrifft, heute nicht da wo ich bin. Was hätte ich ohne deine Weisheiten aus der Tageszeitung manchmal nur getan. Es schmerzt mich nicht mehr dein Student und Kollege zu sein. Wie gern habe ich mit dir gelacht. Auch dir Katrin möchte ich an dieser Stelle danken. Wie so viele habe ich unglaublich viel von dir gelernt und durch unsere Zusammenarbeit, Diskussionen und Anregungen profitiert. Wie aus euch beiden Lehrmeister, Kollegen und schließlich Freunde wurden ist wunderbar. Freunde. Anika - Larissa, das seid ihr, tolle Freundinnen. Anika, unglaublich wie die Zeit angefangen hat zu rasen seit wir uns im Bachelor kennengelernt haben. Wie oft du mich unterstützt hast. Wie oft ich dich mit Fragen und meiner „Überorganisation“ genervt habe. Wie oft wir zusammen Tränen gelacht haben. Larissa, du warst wohl die beste Studentin, die ich hatte und je haben konnte. Was haben wir gelacht, was hatten wir für Spaß. Du bist immer da, bei allem. Vielen Dank! Hannes du warst ein toller Labornachbar und Kollege. Danke, für so viele anregende Diskussionen und überdachte Versuchsplanungen, toll wie oft wir uns gegenseitig geholfen haben. Es war eine schöne Zeit. Auch allen anderen Kollegen und meinen Studenten (Neil, Alex, Erik, Anika, Tenzin) möchte ich hier danken. Ihr habt mir hier seit 2010 (Bachelor bis Doktor) die Arbeit zu einer unvergesslichen Zeit gemacht. Besonders betonen möchte ich die unermüdliche Arbeit und wirklich immer erquickende Art von Silvia, die nicht nur für mich, sondern für dieser Abteilung eine große Bereicherung ist. Miri, was soll ich sagen? Ich wurde aufgenommen, fast rausgeworfen und doch haben wir in den letzten 4 Jahren unglaubliche Momente erlebt. Eine unglaubliche Zeit endet, aber das ist kein Ende! Mit dir kann man Pferde stehlen, Weinkeltereien eröffnen oder HAIdefinition-Filme gucken. Es ist schön wie wir für einander da sind. Danke für alles. Vielen Dank dass du meine Arbeit so gründlich gelesen hast. „s“! Auf viele weitere schöne Momente! III HoMaMaDa oder auch Mama, Papa, Marc, Darleen - selbst wenn ihr fachlich weniger zu der Arbeit beigetragen habt, hätte ich all das nicht ohne euer Zutun geschafft. Ihr habt mir so viel Mut, Stärke und Liebe gegeben und mich immer unterstützt und oft mehr an mich geglaubt als ich selbst. Vielen Dank Marc, dass du meine Launen und meine fehlende Zeit einfach weggesteckt hast und immer zu mir stehst. Es ist schön eine solch unglaublich tolle Familie zu haben. An dieser Stelle möchte ich mich auch bei meinen Prüfern Carsten und Michael bedanken, die immer ein offenes Ohr hatten. Danke auch dir Fabian für immer volle Sektgläser und interessante Diskussionen. Ein Dank gilt auch den weiteren Mitgliedern meines Prüfungskomitees, Prof. Pöggeler und Prof. Urlaub. Vielen Dank auch all den tollen Kooperationspartnern in fast der ganzen Welt - Francis, Ludwig, Juri, Carole, Dan, Carlos, Roger, Maria, und Luis.

  • Investigating Prevalence and Geographical Distribution of Mycoplasma Sp. in the Gut of Atlantic Salmon (Salmo Salar L.)
    Master’s Thesis 2020 60 ECTS Faculty of Chemistry, Biotechnology and Food Science Investigating prevalence and geographical distribution of Mycoplasma sp. in the gut of Atlantic Salmon (Salmo salar L.) Mari Raudstein MSc Biotechnology ACKNOWLEDGEMENTS This master project was performed at the Faculty of Chemistry, Biotechnology and Food Science, at the Norwegian University of Life Sciences (NMBU), with Professor Knut Rudi as primary supervisor and associate professor Lars-Gustav Snipen as secondary supervisor. To begin with, I want to express my gratitude to my supervisor Knut Rudi for giving me the opportunity to include fish, one of my main interests, in my thesis. Professor Rudi has helped me execute this project to my best ability by giving me new ideas and solutions to problems that would occur, as well as answering any questions I would have. Further, my secondary supervisor associate professor Snipen has helped me in acquiring and interpreting shotgun data for this thesis. A big thank you to both of you. I would also like to thank laboratory engineer Inga Leena Angell for all the guidance in the laboratory, and for her patience when answering questions. Also, thank you to Ida Ormaasen, Morten Nilsen, and the rest of the Microbial Diversity group at NMBU for always being positive, friendly, and helpful – it has been a pleasure working at the MiDiv lab the past year! I am very grateful to the salmon farmers providing me with the material necessary to study salmon gut microbiota. Without the generosity of Lerøy Sjøtroll in Bømlo, Lerøy Aurora in Skjervøy and Mowi in Chile, I would not be able to do this work.

  • Bovine Mycoplasmosis
    Bovine mycoplasmosis The microorganisms described within the genus Mycoplasma spp., family Mycoplasmataceae, class Mollicutes, are characterized by the lack of a cell wall and by the little size (0.2-0.5 µm). They are defined as fastidious microorganisms in in vitro cultivation, as they require specific and selective media for the growth, which appears slower if compared to other common bacteria. Mycoplasmas can be detected in several hosts (mammals, avian, reptiles, plants) where they can act as opportunistic agents or as pathogens sensu stricto. Several Mycoplasma species have been described in the bovine sector, which have been detected from different tissues and have been associated to variable kind of gross-pathology lesions. Moreover, likewise in other zoo-technical areas, Mycoplasma spp. infection is related to high morbidity, low mortality and to the chronicization of the disease. Bovine Mycoplasmosis can affect meat and dairy animals of different ages, leading to great economic losses due to the need of prophylactic/metaphylactic measures, therapy and to decreased production. The new holistic approach to multifactorial or chronic diseases of human and veterinary interest has led to a greater attention also to Mycoplasma spp., which despite their elementary characteristics are considered fast-evolving microorganisms. These kind of bacteria, historically considered of secondary importance apart for some species, are assuming nowadays a greater importance in the various zoo-technical fields with increased diagnostic request in veterinary medicine. Also Acholeplasma spp. and Ureaplasma spp. are described as commensal or pathogen in the bovine sector. Because of the phylogenetic similarity and the common metabolic activities, they can grow in the same selective media or can be detected through biomolecular techniques targeting Mycoplasma spp.

Received: 30 June 2020; Accepted: 20 July 2020; Published: 22 July 2020 Abstract: Bacteria of the Mycoplasma genus are characterized by the lack of a cell-wall, the use of UGA as tryptophan codon instead of a universal stop, and their simplified metabolic pathways. Most of these features are due to the small-size and limited-content of their genomes (580–1840 Kbp; 482–2050 CDS). Yet, the Mycoplasma genus encompasses over 200 species living in close contact with a wide range of animal hosts and man. These include pathogens, pathobionts, or commensals that have retained the full capacity to synthesize DNA, RNA, and all proteins required to sustain a parasitic life-style, with most being able to grow under laboratory conditions without host cells. Over the last 10 years, comparative genome analyses of multiple species and strains unveiled some of the dynamics of mycoplasma genomes. This review summarizes our current knowledge of genomic islands (GIs) found in mycoplasmas, with a focus on pathogenicity islands, integrative and conjugative elements (ICEs), and prophages. Here, we discuss how GIs contribute to the dynamics of mycoplasma genomes and how they participate in the evolution of these minimal organisms.

Often associated with restriction modification (RM) systems, they also provide a defence against foreign DNA. Little is known regarding the methylome of the mycoplasma genus, which encompasses several pathogenic species with small genomes. Here, single molecule real-time (SMRT) and bisulphite sequencing combined with whole- genome analysis identified 19 methylated motifs associated with three orphan methyltransferases (MTases) and eight RM systems in Mycoplasma agalactiae, a ruminant pathogen and a model organism. All systems had a homolog in at least one phylogenetically distinct Mycoplasma spp. Our study also revealed that several superimposed genetic events may participate in the M. agalactiae dynamic epigenome landscape. These included (i) DNA shuffling and frameshift mutations that affect the MTase and restriction endonuclease content of a clonal population and (ii) gene duplication, erosion, and horizontal transfer that modulate MTase and RM repertoires of the species.

Accepted 27 November, 2012 The infectious agalactia syndrome occurs worldwide but mainly in the Mediterranean regions, north, central and east Africa, and western Asian countries such as Iran. Mycoplasma agalactiae is the chief causal agent of contagious agalactia. The aim of this research was to use the polymerase chain reaction (PCR) method to isolate and identify M. agalactiae in suspected sheep samples in Iran. They cultured samples from 142 diseased animals and screened them with genus specific PCR oligomers. 59 samples were mycoplasma positive and subsequent testing of these samples with species specific oligomers identified 17 samples that were positive for the agalactiae species of mycoplasma. The derived results established that the detection of M. agalactiae as one of the agents of contagious agalactia in sheep and the prevalence of bacteria in Iranian sheep is lower than that in goats. Key words: Mycoplasma agalactiae, contagious agalactia, identification, sheep, Iran. INTRODUCTION Mycoplasmas consist of wall-less prokaryotes which are infections result in significant losses.

The aim of this study was to isolation mycoplasmas from sheep presenting contagious agalactiae (CA) in Kurdistan in the West of Iran. Materials and Methods: Sixty-nine samples included (milk, conjuctiva swabs, synovial fluid and ear canal swabs) were examined by PCR assay during 2011-2012. DNA was extracted from enriched samples. Two primers (forward and reverse) amplify a 163bp region of 16S rRNA gene of Mycoplasma genus and two primers amplify 375bp region of 16S rRNA gene of Mycoplasma agalactiae (M. agalactiae) species were used. Results: This proved that 46 samples (66.7%) were infected with Mycoplasma in culture and PCR test, respectively. On the PCR test, 15 isolates (32.6%) examined were positive for M. agalactiae that showed specific amplicon at 375bp. All Mycoplasma positive samples were analyzed for M. agalactiae infection by PCR method and 31 isolates (67.4%) examined were negative for M.
