  1. 11. Bacteriological Hygiene in the Production of Pasteurised Milk

    Författare :Åsa Eneroth; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; RAPD; Bacillus cereus; Pseudomonas; Gram-negative; recontamination source; spoilage flora; phychrotrophs; recontamination; dairy hygiene; pasteurised milk; Livsmedelsteknik;

    Sammanfattning : Critical contamination sites and sources for the Gram-negative psychrotrophs (GNP) of the taxa Pseudomonas, Enterobacteriaceae and Aeromonas, and the Gram-positive spore-forming (GPS) species Bacillus cereus, have been traced in the production line of pasteurised milk. Samples of raw and pasteurised milk from different sampling sites along the line were collected. LÄS MER

  3. 12. Antibiotic resistance in Gram-negative bacteria affecting children from León, Nicaragua

    Författare :Erick José Amaya; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Annual child mortality has declined in the world from 12.5 million in 1990 to 8.8 million in 2008. Yet, infectious diseases are still the major cause of death in this group (6. LÄS MER

  4. 13. Molecular basis for trimethoprim and sulphonamide resistance in Gram negative pathogens

    Författare :Malin Grape; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Resistance to antibiotics is becoming an important global public health problem. Infectious diseases are still among the major causes of disease and death in many parts of the world and the possibilities to treat bacterial infections are now threatened due to the spread of antibiotic resistance.

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

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

    Sammanfattning : 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. LÄS MER

  7. 15. Signalling and activation of TLR4 by Gram-negative bacteria in epithelial cells

    Författare :Lisa Meijer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Lipopolysaccharide (LPS) is a well-characterized pathogen-associated molecule found primarily as a constituent of the outer membrane of Gram-negative bacteria. LPS is known to act on different cell types in a pleiotropic manner. LÄS MER
