  2. 1. Bacterial viruses targeting multi-resistant Klebsiella pneumoniae and Escherichia coli

    Author : Harald Eriksson; Anders Nilsson; Elisabeth Haggård-Ljungquist; Klas Flärdh; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacterial viruses; Bacteriophage; Phage; Phage therapy; multi-resistant bacteria; Klebsiella pneumoniae; molekylärgenetik; Molecular Genetics;

    Abstract : The global increase in antibiotic resistance levels in bacteria is a growing concern to our society and highlights the need for alternative strategies to combat bacterial infections. Bacterial viruses (phages) are the natural predators of bacteria and are as diverse as their hosts, but our understanding of them is limited. READ MORE

  4. 2. Coevolution and molecular background of species interactions in geographic mosaics

    Author : Xuyue Yang; Peter A. Hambäck; Michael R. Strand; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcriptomics; population genetics; insect immunology; parasitoid; genome assembly; natural selection; Ecology and Evolution; ekologi och evolution;

    Abstract : In complex food webs, species often interact with each other indirectly through mediating species. As a result of geographic mosaic of coevolution, such interactions are often evolutionarily unstable and the traits governing the interaction sometimes vary over time. READ MORE

  5. 3. Study of phages for phage therapy : An Escherichia coli experience

    Author : Mohammadali Khan Mirzaei; Anders Nilsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

    Abstract : The world is rapidly moving toward a post-antibiotic era as effective antibiotics are becoming fewer. phage therapy is a potentially possible method for treating infectious diseases and counts as an alternative method for antibiotic therapy. READ MORE

  6. 4. Response to wheat dwarf virus in wild and domesticated wheat : genetic resources of evolutionary and environmental origins

    Author : Jim Nygren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wild and domesticated plants are constantly exposed to a variety of pathogens, which may trigger an arms race in evolution of defense strategies in the plant and development of virulence in the pathogen. The outcome of the interaction depends on the intensity of reciprocal selection between the interacting species, which may vary over space and time, explained as the geographic mosaic theory of coevolution.

  7. 5. Virulence Factors and Motility Mechanisms of Pathogenic Neisseria

    Author : Jens Eriksson; Ann-Beth Jonsson; Helena Aro; Tone Tønjum; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria; Virulence factors; Type IV pili; PilT; PilU; NafA; NhhA; Twitching motility; molekylärgenetik; Molecular Genetics;

    Abstract : Neisseria gonorrhoeae and Neisseria meningitidis are two closely related human specific pathogens. Neisseria gonorrhoeae is the causative agent for the sexually transmitted disease gonorrhea and often causes asymptomatic infections in women which is a cause of infertility. READ MORE
