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. -

However, comparative genomics revealed that proteins’ length may be affected by additional factors. In 2002 it was shown that in bacterium Escherichia coli and the archaeon Archaeoglobus fulgidus, protein sequences with no homologs are, on average, shorter than those with homologs [1]. Most experts now agree that the length distributions are distinctly different between protein sequences with and without homologs in bacterial and archaeal genomes. In this study, we examine this postulate by a comprehensive analysis of all annotated prokaryotic genomes and focusing on certain exceptions. -

Autism Research Directory Evidence for Mycoplasma Ssp., Chlamydia Pneunomiae, and Human Herpes V

Nicolson,1 and Joerg Haier1,2 1The Institute for Molecular Medicin e, Huntington Beach, California 2Department of Surgery, University Hospital, Muns ter, Germany We examined the blood of 48 patients from central and southern California diagnosed with autistic spectrum disorders (ASD) by using forensic polymerase chain reaction and found that a large subset (28/48 or 58.3%) of patients showed evidence o f Mycoplasma spp. Infections compared with two of 45 (4.7%) age -matched control subjects (odds ratio = 13.8, P < 0.001). Because ASD patients have a high prevalence of one or more Mycoplasma spp. and sometimes show evidence of infections with Chlamydia pne umoniae, we examined ASD patients for other infections. Also, the presence of one or more systemic infections may predispose ASD patients to other infections, so we examined the prevalence of C. pneumoniae (4/48 or 8.3% positive, odds ratio = 5.6, P < 0. 01) and human herpes virus -6 (HHV - 6, 14/48 or 29.2%, odds ratio = 4.5, P < 0.01) coinfections in ASD patients. We found that Mycoplasma -positive and -negative ASD patients had similar percentages of C. pneumoniae and HHV -6 infections, suggesting that su ch infections occur independently in ASD patients. Control subjects also had low rates of C. pneumoniae (1/48 or 2.1%) and HHV -6 (4/48 or 8.3%) infections, and there were no oinfections in control subjects. The results indicate that a large subset of ASD patients shows evidence of bacterial and/or viral infections (odds ratio ¼ 16.5, P < 0.001). -

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. -

Attachment 1 .PLOS ONE
Attachment 1 .PLOS ONE CORRECTION Correction: Exposure of bighorn sheep to domestic goats colonized with Mycoplasma ovipneumoniae induces sub-lethal pneumonia Thomas E. Besser, E. Frances Cassirer, Kathleen A. Potter, William J. Foreyt Tn response to queries raised after publication, the authors, the authors’ institution (Office of Research Assurance, Washington State University) and a member of PLOS ONE’s Editorial Board have reviewed the findings in this article, and as a consequence the authors provide an update to the Competing Interests statement and clarifications regarding the results: The competing interests declaration is updated to acknowledge additional sources of fund ing received by the authors. This specific study was supported by funding competitively awarded by the Wild Sheep Foundation and by revenue from the WSU Rocky Crate Endow ment for Wild Sheep Disease Research. Additional research funding for the authors’ bighorn sheep pneumonia-related research has been received from the US Department of Agriculture (including the Animal Plant Health Inspection Service and the US Forest Service), the US Geo logic Survey, numerous chapters and affiliates of the Wild Sheep Foundation, and the WSU Fowler Emerging Infectious Diseases endowment. Regarding the pneumonia diagnosis reported in the article, the authors re-assessed the pri mary data and solicited and received a second opinion from a veterinary pathologist at Wash ington Animal Disease Diagnostic Lab (WADDL) unassociated with the original project. Following this reassessment, the authors confirmed the descriptions and diagnoses as reported in the article, but they noted that the consulted pathologist advised, “some pathologists might describe the histopathologic lesions seen in the least severely affected animal as ‘bronchiolitis’ rather than ‘pneumonia’ due to the preponderance of that lesion in that animal”.
