  1. 1. An Overview Of The Antibiotic Resistance Mechanisms Of Common Gram Positive And Gram Negative Multidrug Resistant Bacteria

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Elisabeth Tammi; [2023]
    Nyckelord :Antibiotic resistance mechanism; gram negative bacteria; gram positive bacteria;

    Sammanfattning : Antibiotic resistance in multidrug resistant bacteria cause high mortality rates worldwide, where there has been over 1,000,000 deaths reported as of the year 2019. Antibiotics were thought to be the cure for fighting infectious diseases and preventing further spreading of infection. LÄS MER

  3. 2. Construction and Evaluation of a Cre-lox-Based Fluorescent Conjugation Tracking System

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

    Författare :Carl Brännström; [2022]
    Nyckelord :Antibiotic resistance; horizontal gene transfer; plasmids; conjugation; conjugational frequency; Cre loxP system;

    Sammanfattning : Plasmids are small, circular, extrachromosomal double-stranded genetic elements present in bacteria. Plasmids can replicate independently of the bacterial chromosome and play an important role as a transmitter of antibiotic resistance genes between bacteria. LÄS MER

  4. 3. The use of a CRISPR-Cas9 system to protect probiotic strains from transferrable drug resistance genes

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Sara Lundberg; [2021]
    Nyckelord :CRISPR-Cas9; antibiotic resistance; horizontal gene transfer; probiotic bacteria;

    Sammanfattning : The discovery of antibiotics have revolutionized modern medicine, facilitating the treatment of a variety of bacterial infections, enabled surgeries otherwise impossible to perform and increased life expectancy in all countries. However, the rapid development of resistance among microorganisms and the increasing numbers of clinical outbreaks caused by multiresistant bacteria have accelerated the need for new alternatives to antibiotics.

  5. 4. Vinst och förlust : en fylogenetisk studie av kloroperoxidas-liknande enzym hos jästsvampar

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Beatrice Bylén; [2021]
    Nyckelord :fylogenetik; sekvenshomologi; Saccharomycotina; knoppjästsvamp; HGT; genförlust; α β-hydrolas; kloroperoxidas;

    Sammanfattning : Knoppjästsvampar är en typ av svampar med encellig morfologi. Knoppjästsvampar utgör Saccharomycotina, en understam till Ascomycota och innefattar mer än 1000 idag beskrivna arter, bland annat bakjästen Saccharomyces cerevisiae. Trots att S. LÄS MER

  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
