  2. 1. Pharmacokinetic and Pharmacodynamic Modeling of Antibiotics and Bacterial Drug Resistance

    Author : Ami Fazlin Syed Mohamed; Lena Friberg; Teresa Dalla Costa; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; pharmacokinetics; pharmacodynamics; modeling; antibiotics; resistance; combination; Gram-negative bacteria; gentamicin; colistin; meropenem; newborn infants; critically ill patients; Infectious Diseases; Infektionssjukdomar; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : Exposure to antibiotics is an important factor influencing the development of bacterial resistance.  In an era where very few new antibiotics are being developed, a strategy for the development of optimal dosing regimen and combination treatment that reduces the rate of resistance development and overcome existing resistance is of utmost importance.

  4. 2. Optimization of Colistin Dosage in the Treatment of Multiresistant Gram-negative Infections

    Author : Matti Karvanen; Otto Cars; Lena E Friberg; Vincent H Tam; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colistin; CMS; Pharmacology; Pharmacokinetics; PKPD; Antibiotics; Combination therapy; Pharmacometrics; Dosing regimens; Antibiotic resistance; Infectious Diseases; Infektionssjukdomar;

    Abstract : As multidrug resistance in Gram-negative bacilli increases, the old antibiotic colistin has rapidly gained attention as one of few last line treatment options in the form of colistin methanesulfonate (CMS), which is hydrolyzed to colistin both in vitro and in vivo. There is a dearth of knowledge on fundamental aspects of colistin, including pharmacokinetics and optimal dosing regimens. READ MORE

  5. 3. Multi-Resistance Plasmids : Fitness Costs, Dynamics and Evolution

    Author : Fredrika Rajer; Linus Sandegren; Pål Jarle Johnsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multi-resistance plasmids; evolution; fitness cost; dynamics; escherichia coli; ESBL; gene amplification; β-lactamase inhibitor; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Antibiotic resistance is an escalating problem, not only due to less desirable treatment options and outcome, but also due to the economic burden to health care caused by resistant pathogens. Since the process of developing new antibiotics is slow, we need to carefully consider the usage of the antibiotics still available. READ MORE

  6. 4. β-lactam combinations against multidrug-resistant Enterobacterales : Exploring combination effects and resistance development

    Author : Lisa Allander; Thomas Tängdén; Linus Sandegren; Pernilla Lagerbäck; Arnfinn Sundsfjord; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gram-negative bacteria; antibiotic combination therapy; antibiotic resistance; beta-lactams; beta-lactamase inhibitors; Infektionssjukdomar; Infectious Diseases;

    Abstract : The β-lactam antibiotics are a cornerstone in treating bacterial infections, but the increasing prevalence of antibiotic resistance worldwide threatens their effectiveness. The main driver of β-lactam resistance is the production of β-lactamases, which are bacterial enzymes that inactivate the antibiotic. READ MORE

  7. 5. Studies on cell wall recycling and modification in Gram-negative bacteria

    Author : Michael C. Gilmore; Felipe Cava; Peter A Lind; Teresa Frisan; Jean-François Collet; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptidoglycan recycling; bacterial cell wall; antibiotics; Agrobacterium tumefaciens; Escherichia coli; Legionella pneumophila; mikrobiologi; Microbiology; Biochemistry; biokemi;

    Abstract : The bacterial cell wall is made from peptidoglycan (PG), a heteropolymer which forms a bag-like exoskeleton that envelopes the cell. PG is constantly remodelled during growth and division, and in response to environmental stimuli. READ MORE
