  1. 1. Nanometa Live : A real-time metagenomic analysis pipeline and interface for species classification and pathogen characterization

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Kristoffer Sandås; [2023]
    Nyckelord :;

    Sammanfattning : Metagenomics studies the totality of genomes of all species in a microbial community. It is a young, growing field with medical, industrial, and ecological applications. Abundant metagenomic data is being produced today, but there is a lack of interpretation and visualization tools. LÄS MER

    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  4. 3. Determining Leptosphaeria species on Swedish oilseed rape and monitoring responses to Fusarium avenaceum and Fusarium graminearum in timothy populations

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Wijesuriya Arachchige Anushka Priyangi Athukorala; [2021]
    Nyckelord :Leptosphaeria maculans; Leptospharia biglobosa; Fusarium avenaceum; Fusarium graminearum; Sclerotinia trifoliorum; black leg disease; root rot and crown rot;

    Sammanfattning : Background Phoma stem canker or black leg disease is one of the most important disease affecting the oil seed rape worldwide. The disease is caused by the two pathogen species Leptosphaeria maculans and L. biglobosa. In this study genomic information of L. LÄS MER

  5. 4. The transfer of chromosomal genes through bacterial conjugation in Escherichia coli

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Arijana Katana; [2021]
    Nyckelord :conjugation; escherichia coli; hybrid;

    Sammanfattning : Evolution in bacteria occurs through the combined effects of spontaneous mutations and horizontal gene transfer (HGT). Several mechanisms can lead to HGT: (i) transformation, the uptake of DNA from the environment; (ii) transduction, the transfer of DNA carried by a bacteriophage into another bacterium during infection; and (iii) conjugation, bacterial mating mediated by a conjugative plasmid like the F-factor.

  7. 5. The Importance of Bacterial Replichore Balance

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Ender Efe Cerit; [2021]
    Nyckelord :Salmonella; bacterial evolution; fitness cost; chromosome organization and structure; chromosomal inversion; replichore; horizontal gene transfer;

    Sammanfattning : In most bacterial pathogens, the genome is comprised within a single circular chromosome which is typically organized by the origin-to-terminus axis that divides the chromosome into equally-sized arms of replication (replichores). This similarity in length is presumed to be required for the synchronization of the two replication forks to meet at the terminus for efficient chromosome segregation. LÄS MER
