  2. 1. Inflammatory mediator response to Gram-positive and Gram-negative bacteria in vitro and in middle ear infections

    Author : Susann Skovbjerg; Göteborgs universitet; []
    Keywords : Gram-positive; Gram-negative; bacteria; cytokines; monocytes macrophages; phagocytosis; Streptococcus pneumoniae; autolysin; acute otitis media; secretory otitis media; children; probiotics;

    Abstract : Based on the structure of the cell wall, bacteria are divided into Gram-positive and Gram-negative. While the cell wall of Gram-positive bacteria is thick, the cell wall of Gram-negatives is very thin and surrounded by an outer membrane with LPS. READ MORE

  4. 2. Regulation of innate and adaptive immune responses by Gram-positive and Gram-negative bacteria

    Author : Anna Martner; Göteborgs universitet; []
    Keywords : Gram-positive; Gram-negative bacteria; Streptococcus pneumoniae; IL-12; autolysin; pneumolysin; CD4 T cells; monocytes macrophages; dendritic cells;

    Abstract : Bacteria are classified as Gram-positive or Gram-negative, depending on their cell wall structure. The role of the bacterial cell wall in immune regulation is the focus of the current work. Most Gram-positive bacteria stimulate monocytes to produce large amounts of IL-12. READ MORE

  5. 3. Exploring the mechanistic details of Gram-positive Type 4 Secretion Systems

    Author : Lena Lassinantti; Ronnie Berntsson; A. Elisabeth Sauer-Eriksson; Sjoerd Wanrooij; Samuel Wagner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial resistance; Horizontal gene transfer; Gram-positive bacteria; Type 4 Secretion Systems; Conjugation; Enterococcus faecalis; pCF10; PrgU; PcfF; PrgB; Biochemistry; biokemi;

    Abstract : Hospital acquired (i.e. nosocomial) infections and antibiotic resistance are large issues in the world today, with about 1.3 million people estimated to have died from antibiotic resistant infections in 2019 alone, and these problems are on the rise. READ MORE

  6. 4. Bacteriological Hygiene in the Production of Pasteurised Milk

    Author : Åsa Eneroth; Livsmedelsteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. The Gut Bacterial Flora - Focus on Early Life and Physiological Traits

    Author : Caroline Linninge; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gut microbiota; atopic eczema; inflammation; bacterial diversity; Escherichia coli; Lactobacillus plantarum; molecular-genetic methods;

    Abstract : The gastrointestinal tract of the foetus is considered sterile but during vaginal birth the neonate comes into contact with bacteria from the maternal vaginal and intestinal microbiota. The main focus of this doctoral thesis was to elucidate the initial bacterial ecosystem in newborns and to relate microbial perturbations to physiological traits. READ MORE
