  1. 1. Antimicrobials in sewage treatment plants : occurrence, fate and resistance

    Author : Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

    Abstract : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. READ MORE

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

    Author : Lisa M. Albrecht; Dan I Andersson; Alex O'Neill; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Towards Anti-Virulence Antimicrobials, Discovery and Development of Sortase A Inhibitors and Investigations of Bacterial Phenotypes

    Author : Patrick M. Wehrli; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sortase A; SrtA; Inhibitors; Anti-virulence; Bacterial analysis; FTIR spectroscopy; Bacterial phenotyping; Design of Experiment; Multivariate Data Analysis; PCA; ToF-SIMS; Time-of-flight secondary-ion-mass-spectrometry; Lipid analysis; ppGpp; Stringent response;

    Abstract : Antibiotic resistance is an emerging and serious threat to public health. Immediate actions are required to preserve current antibiotics while intensifying research efforts towards the development of new effective therapeutics. READ MORE

  4. 4. Antimicrobial resistant Escherichia coli in faeces from preweaned dairy calves : prevalence, risk factors, and spread

    Author : Anna Duse; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : Antimicrobial resistant (AMR) bacteria are increasing threats for human and veterinary medicine. Faecal Escherichia coli (E. coli) from preweaned dairy calves is often resistant to multiple antimicrobials and calves may therefore serve as reservoirs for these bacteria and their resistance genes.

  5. 5. Bio-based nonionic antimicrobial polymers with isatin or indole functionality

    Author : Xiaoya Li; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antimicrobial polymers; nonionic; isatin; indole; miscibility; hemolytic activity; cytotoxicity;

    Abstract : Infections by pathogenic microorganisms remain one of the most serious concerns in several areas, particularly in hygienic applications. Antimicrobials have been used to combat these infections. Using small molecular antimicrobials as additives or coatings is an industrially adopted strategy. READ MORE
