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. Bacterial Resistance to Antimicrobial Peptides : Rates, Mechanisms and Fitness Effects

   Författare :Maria Pränting; Dan Andersson; Ian Chopra; Uppsala universitet; []
   Nyckelord :antimicrobial peptides; antibiotic resistance; fitness cost; bacterial evolution; small colony variants; cyclotides; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Mikrobiologi; Microbiology;

   Sammanfattning : The rapid emergence of bacterial resistance to antibiotics has necessitated the development of alternative treatment strategies. Antimicrobial peptides (AMPs) are important immune system components that kill microbes rapidly and have broad activity-spectra, making them promising leads for new pharmaceuticals. 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. Surveillance of Antibiotic Consumption and Antibiotic Resistance in Swedish Intensive Care Units

   Författare :Marcus Erlandsson; Håkan Hanberger; Nils Smith-Erichsen; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacterial Antibiotic resistance; Antibiotic Consumption; ICU; Surveillance programme; Multi drug resistance; Pseudomonas aeruginosa; ICU demography; Infectious diseases; Infektionssjukdomar;

   Sammanfattning : Introduction: Nosocomial infections remain a major cause of mortality and morbidity. The problem is most apparent in intensive care units (ICUs). Most ICU patients are compromised and vulnerable as a result of disease or severe trauma. One in ten people admitted to hospital is given an antibiotic for infection. LÄS MER
