  2. 1. Functional Profiling Of Metabolic Regulation In Marine Bacteria

    Author : Saraladevi Muthusamy; Jarone Pinhassi; Torsten Thomas; Sarala Devi Muthusamy; Institutionen för biologi och miljö (BOM) Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine microbiology; physiology; heterotrophic bacteria; adaptive strategies; survival; proteomics; growth phase; proteorhodopsin; inorganic sulphur oxidation; anaplerotic CO2 fixation; Miljövetenskap; Environmental Science;

    Abstract : Oceans are powered by active, metabolically diverse microorganisms, which are important in regulating biogeochemical cycles on Earth. Most of the ocean surface is often limited by nutrients, influencing bacterial growth and activities. READ MORE

  4. 2. Dissemination of Multiresistant Bacteria : Their Selection, Transmission, Virulence and Resistance

    Author : Gustaf Starlander; Åsa Melhus; Jørgen Vildershøj Bjørnholt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk bakteriologi; Clinical Bacteriology;

    Abstract : Multiresistant bacteria are an emerging threat in modern medicine. Consumption of antimicrobial agents among humans, animals and in agriculture causes a selection of resistance genes. READ MORE

  5. 3. 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

  6. 4. Gut microbiota in colorectal cancer : The importance of Parvimonas micra

    Author : Thyra Löwenmark; Richard Palmqvist; Sofia Edin; Pär Larsson; Michael Dahlberg; Per Hellström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; mucosal microbiota; Parvimonas micra; Fusobacterium nucleatum; immunity; survival; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Abstract : Colorectal cancer (CRC) is a heterogenous disease consisting of multiple molecular subtypes, each of which has diverse treatment responses and prognoses. The importance of the gut microbiota in CRC development and progression has undergone increasing recognition in recent years, with a structural segregation in terms of microbial composition between CRC patients and healthy controls.

  7. 5. Molecular mechanisms and biological consequences of the production of non-canonical D-amino acids in bacteria

    Author : Alena Aliashkevich; Felipe Cava; Fredrik Almqvist; Andrew J Roe; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacteria; cell wall; peptidoglycan; D-amino acids; LD-transpeptidase;

    Abstract : Most bacteria possess a vital net-like macromolecule – peptidoglycan (PG). PG encases bacteria around the cytoplasmic membrane to withstand the high internal turgor pressure and thereby protect the cell from bursting. In addition, PG is a major morphological determinant of bacteria being both required and sufficient to maintain cell shape. READ MORE
