  1. 6. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota

    Författare :Nahid Karami; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ampicillin; tetracycline; in vivo fitness; persistence; gene transfer; intestinal; blaTEM Escherichia coli;

    Sammanfattning : Microbial resistance to antibiotics is a growing problem worldwide. Resistance develops not only in microbes which are the targets of the antibiotic treatment, but also in those belonging to the normal microbiota of the treated host. Little is known on the ecological consequences of antibiotic resistance in commensal bacteria. LÄS MER

    Sammanfattning : Neisseria meningitidis, also known as the meningococcus, is a globally spread obligate human bacterium causing meningitis and/or septicaemia. It is responsible for epidemics in both developed and developing countries. LÄS MER

  4. 8. Evolution and Mechanisms of Tigecycline Resistance in Escherichia coli

    Författare :Marius Linkevičius; Dan I. Andersson; Linus Sandegren; Patrice Courvalin; Uppsala universitet; []
    Nyckelord :Tigecycline; Bacterial resistance; Fitness; Escherichia coli; AcrAB; LPS; Tet proteins; Tet A ; Tet K ; Tet M ; Tet X ; tet genes; pUUH239.2; Mikrobiologi; Microbiology;

    Sammanfattning : Antibiotic resistance is an ongoing global medical crisis and we are in great need of new antibacterial agents to combat rapidly emerging resistant pathogens. Tigecycline is one of few drugs that have been introduced into medicine during the last two decades. LÄS MER

  5. 9. Fluoroquinolone resistance in the environment and the human gut – Analysis of bacterial DNA sequences to explore the underlying genetic mechanisms

    Författare :Anna Johnning; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antimicrobial resistance; Quinolones; Pollution; Next generation sequencing; Bioinformatics; Next generation sequencing;

    Sammanfattning : Fluoroquinolones (FQs) are synthetic, broad-spectrum antibiotics that target type II topoisomerases. High-level resistance is often caused by mutations in the target genes of FQs, especially in gyrA and parC. In contrast, plasmid-mediated resistance genes, such as qnr, often confer moderate levels of resistance. LÄS MER

  7. 10. Antibiotic resistance in Lactobacillus reuteri and Lactobacillus plantarum

    Författare :Maria Egervärn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Lactic acid bacteria (LAB) may act as reservoirs of antibiotic resistance genes that can be transferred via the food chain or within the gastrointestinal tract to pathogenic bacteria. This thesis provides data required for assessing the potential risk of using antibiotic resistant strains of the LAB species Lactobacillus reuteri and Lactobacillus plantarum as food processing aids or probiotics.
