  2. 1. Disarming bacteria : a structure-based approach to design an anti-virulence drug against Listeria monocytogenes

    Author : Melanie Oelker; A. Elisabeth Sauer-Eriksson; Fredrik Almqvist; Karina Persson; Tiziano Tuccinardi; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antibiotic resistances; anti-virulence drug; Listeria monocytogenes; virulence regulation; PrfA; structure-based drug design; ring-fused 2-pyridones; allosteric regulation; Biochemistry; biokemi; medicinal chemistry; läkemedelskemi; molekylär cellbiologi; molecular cell biology; medicinsk biokemi; Medical Biochemistry; molekylärbiologi; Molecular Biology;

    Abstract : Antibiotic resistances are one of the biggest threats to global health and if we don’t change our behavior and way of using antibiotics we will end up in a ‘post-antibiotic era’, in which common infections and minor injuries can once kill again and up to 10 million deaths per year may occur by 2050. Therefore, there is a high need for new anti-bacterial drugs, especially of alternatives to existing antibiotics with already described resistances. READ MORE

  4. 2. Bacteria that escape predation : waterborne pathogens and their relatives

    Author : Karolina I. A. Eriksson; Agneta Andersson; Johanna Thelaus; Jon Ahlinder; David Sundell; Klaus Jürgens; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial pathogens; protozoa; predation resistance; aquatic microbiology; climate change; opportunists; humification; iron; environmental science; miljövetenskap; mikrobiologi; Microbiology;

    Abstract : The hidden presence of opportunistic bacterial pathogens in the environment evokes concerns about emerging diseases, especially in the light of climate change. The co-evolution of bacteria and their predators (protozoa) has led to bacterial defence strategies of which some contribute to the ability of bacteria to cause disease. READ MORE

  5. 3. Antimicrobial materials from cellulose using environmentally friendly techniques

    Author : Anna Ottenhall; Monica Ek; Josefin Illergård; Orlando Rojas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; antifungal; cellulosic; mold; bacteria; biobased; bio-based; renewable; insulation; packaging; water treatment; water purification; paper filter; paper; membrane; Antibakteriell; fungicid; mögel; antimögel; pappersfilter; vattenrening; membran; papper; bakterier; cellulosa; förpackning; isolering; förnyelsebar; biobaserade; nya material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

  6. 4. Oviposition cues as a tool for developing a new malaria control strategy

    Author : Lynda Eneh; Anna-Karin Borg-Karlson; Willem Takken; KTH; []
    Keywords : Anopheles gambiae; Malaria; Oviposition; Volatile compounds; GC-MS; DGGE; Sorption; Fungi; Bacteria; Physicochemical parameters; Nut grass; Bermuda grass; Anopheles gambiae; Malaria; Äggläggning; Flyktiga ämnen; GC-MS; DGGE; Sorptionen; Svampar; Bakterier; Gräs; Kemi; Chemistry;

    Abstract : Anopheles gambiae sensu lato mosquitoes are among the dominant malaria vectors in sub-Saharan Africa. However, not much is known about the oviposition behaviour of these species necessary for the development of malaria vector control strategies. READ MORE

  7. 5. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments

    Author : Sven Iburg; Francisco J. A. Nascimento; Owen Wangensteen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soft sediments; benthic ecosystems; anthropogenic disturbance; contamination; recreational boating; bottom trawling; meiofauna; bacteria; metabarcoding; Baltic Sea; mjuka sediment; bentiska ekosystem; antropogenisk påverkan; förorening; fritidsbåtar; bottentrålning; meiofauna; bakterier; metabarcoding; Östersjön; marin ekologi; Marine Ecology;

    Abstract : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. READ MORE
