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

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

    Abstract : 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. READ MORE

  4. 2. Chemical use in shrimp farming and environmental implications of antibiotic pollution

    Author : Sara Gräslund; Nils Kautsky; Bent Halling-Sørensen; Stockholms universitet; []
    Keywords : ;

    Abstract : Shrimp farming is a highly important industry in southeast Asia. A major threat to profitable shrimp farming is disease outbreaks, which has lead to a situation where a large number of chemicals are used to prevent and treat infections. READ MORE

  5. 3. Antibiotic prescribing : focusing on the situation in Swedish nursing homes

    Author : Eva Pettersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : antibiotic prescribing;

    Abstract : Background: The increasing rate of resistance to antibiotics has become a global concern. High consumption and irrational use of antibiotics is contributing to this development. READ MORE

  6. 4. Quinolone resistance in Bacteroides fragilis and Pseudomonas aeruginosa, two opportunistic pathogens

    Author : Herin Oh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Quinolone; resistance; B. fragilis; P. aeruginosa; topoisomerase; efflux;

    Abstract : Opportunistic pathogens can cause infections in case of structural or functional defects in the host. Examples of Gram-negative opportunists are the Bacteroides fragilis group, anaerobic, non-spore forming rods and the aerobic, non-fermentative rod Pseudomonas aeruginosa. READ MORE

  7. 5. Data-Driven Methods for Surveillance and Diagnostics of Antibiotic-Resistant Bacteria

    Author : Juan Salvador Inda Díaz; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antibiotic resistance; metagenomics; data-driven diagnostics; transformers;

    Abstract : Antimicrobial resistance is a rapidly growing challenge for the healthcare sector and multi-drug resistant bacterial infections are the cause of nearly a million deaths annually worldwide. Antibiotic resistance is conferred by either antibiotic resistance genes (ARGs) which can be acquired by horizontal gene transfer between bacterial cells or by mutations in pre-existing DNA. READ MORE
