1. 1. Antibiotic Resistance : Selection in the Presence of Metals and Antimicrobials

   Författare :Lisa M. Albrecht; Dan I Andersson; Alex O'Neill; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; Metals; Antimicrobials; Bacterial evolution; Bacterial genetics; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

   Sammanfattning : The external environment is complex: Antibiotics, metals and antimicrobials do not exist in isolation but in mixtures. Human activities such as animal husbandry, fertilization of agricultural fields and human medicine release high amounts these compounds into the environment. LÄS MER

3. 2. Antibiotic Resistance in Wastewater : Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

   Författare :Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; Microbiology; Mikrobiologi;

   Sammanfattning : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. LÄS MER

4. 3. Antibiotic resistance gone wild : A One Health perspective on carriage, selection and transmission of Extended-Spectrum Cephalosporinase- and Carbapenemase-producing Enterobacteriaceae

   Författare :Clara Atterby; Josef D. Järhult; Nicola Williams; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; E. coli; K. pneumoniae; ESBL; AmpC; Carbapenemase; ciprofloxacin resistance; colistin resistance; rural; wildlife; birds; sub-MIC; MSC; Cambodia; environment; epidemiology; Infektionssjukdomar; Infectious Diseases;

   Sammanfattning : Antibiotics have saved millions of lives since they came into clinical use during the Second World War in the 1940s. Today, our effective use of antibiotics is under great threat due to emerging antibiotic resistance in bacteria. This thesis addresses the problems of antibiotic resistance from a ”One Health” perspective. LÄS MER

5. 4. On the Origins of mobile Antibiotic Resistance Genes : A comparative genomics approach

   Författare :Stefan Ebmeyer; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotic resistance; comparative genomics; bacterial genomics; antibiotic resistance genes;

   Sammanfattning : Mobile antibiotic resistance genes (ARGs), transferable between bacterial cells, are major contributors to the antibiotic resistance crisis we are facing today. From which organisms pathogens acquired these genes is mostly unknown, yet knowledge about their origin is needed in order to limit the emergence and spread of novel ARGs in the future. LÄS MER

7. 5. New antibiotic resistance genes and their diversity

   Författare :Fanny Berglund; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; β-lactamases; hidden Markov model; antibiotic resistance; carbapenemases; big data; tetracycline resistance;

   Sammanfattning : Antibiotic resistance is increasing worldwide and is considered a severe threat to public health. Often, antibiotic resistance is caused by antibiotic resistance genes, of which many are hypothesized to have been transferred into human pathogens from environmental bacteria. LÄS MER
