  2. 1. Selection of Resistance at very low Antibiotic Concentrations

    Author : Erik Gullberg; Dan I Andersson; Diarmaid Hughes; Linus Sandegren; Laura Piddock; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Selection; Antibiotic resistant bacteria; Minimal inhibitory concentration; Heavy metals; Conjugative plasmid; ESBL; Mikrobiologi; Microbiology; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : The extensive medical and agricultural use and misuse of antibiotics during the last 70 years has caused an enrichment of resistant pathogenic bacteria that now severely threatens our capacity to efficiently treat bacterial infections. While is has been known for a long time that high concentrations of antibiotics can select for resistant mutants, less is known about the lower limit at which antibiotics can be selective and enrich for resistant bacteria.

  4. 2. Biological and Pharmacological Factor that Influence the Selection of Antibiotic Resistance

    Author : Ingegerd Gustafsson; Otto Cars; Niels Frimodt-Möller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Human microflora; antibiotic resistance; selection; mutation frequency; biological fitness; pharmacokinetics; pharmacodynamics; β-lactam antibiotics; suboptimal dosing regimen; Mikrobiologi; Microbiology; Mikrobiologi; Klinisk bakteriologi; Clinical Bacteriology;

    Abstract : Antibiotic treatment causes an ecological disturbance on the human microflora. Four commensal bacteria: E. coli, enterococci, a-streptococci and coagulase-negative staphylococci, from patients with extensive, high antibiotic usage were investigated with regard to resistance pattern and mutation frequency.

  5. 3. Chlamydia pneumoniae in Aortic Valve Sclerosis and Thoracic Aortic Disease : Aspects of Pathogenesis and Therapy

    Author : Christina Nyström-Rosander; Kenneth Persson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; Chlamydia pneumoniae; aortic valve sclerosis; trace elements; thoracic aorta; antibiotics; Polymerase Chain Reaction PCR ; electron microscopy EM ; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar; infektionssjukdomar; Infectious Diseases;

    Abstract : The obligate intracellular bacterium Chlamydia pneumoniae (Cp), a common human pathogen, has been associated with atherosclerotic cardiovascular disease. The aetiology of non-rheumatic aortic valve sclerosis has, however, not been clarified. READ MORE

  6. 4. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis

    Author : Ratana Lawung; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Metabolism; Biochemistry; enzyme calorimeter; site-directed mutagenesis; ampicillin resistance plasmid; Haemophilus ducreyi; TEM-1 b-lactamase; metabolism; Proteins; enzymology; Proteiner; enzymologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. READ MORE

  7. 5. Antibiotic interactions and selection for resistance in biofilms

    Author : Po-Cheng Tang; Dan I. Andersson; Karin Hjort; Mark Webber; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotics; Mikrobiologi; Microbiology;

    Abstract : The challenges posed by antibiotic-resistant bacteria in treating infections, particularly those associated with biofilms, require a deeper understanding of this lifestyle and its connection to resistance selection. Additionally, gaining insights into drug interactions is crucial for enhancing combination treatment efficacy and mitigating resistance development. READ MORE
