1. 41. Signaling and transcriptional regulation of antimicrobial peptide genes in Drosophila melanogaster

   Författare :Hanna Uvell; Ylva Engström; Won-Jae Lee; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antimicrobial peptides; drosophila; immunity; transcriptiona regulation; Molecular biology; Molekylärbiologi;

   Sammanfattning : Insects rely solely on innate immune reactions for protection against infect-ing microbes in their environment. In Drosophila, one major defense mechanism is the production of a battery of antimicrobial peptides (AMPs). LÄS MER

4. 43. Porphyrins and heme in microorganisms : Porphyrin content and its relation to phototherapy and antimicrobial treatments in vivo and in vitro

   Författare :Jonas Fyrestam; Conny Östman; Jonas Bergquist; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porphyrins; heme; phototherapy; antimicrobial resistance; singlet oxygen; photosensitizer; bacteria; HPLC-MS MS; oral bacteria; Aggregatibacter actinomycetemcomitans; Porphyromonas gingivalis; Escherichia coli; Analytical Chemistry; analytisk kemi;

   Sammanfattning : One of the greatest threats to human health is increasing antimicrobial resistance among pathogens, and finding alternatives for treatment of bacterial infections is of highest importance together with a more controlled use of antibiotics. Porphyrins and heme have both been shown to be a promising class of compounds for inactivation of bacteria; porphyrins by their excellent properties to act as a photosensitizer, and heme by its importance as an iron source during a bacterial infection in vertebrates.

5. 44. Production, Purification and Characterization of Antimicrobial Biomolecules from Potential Probiotic Lactic Acid Bacteria

   Författare :Sahar Deraz; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactobacillus; Bioteknik; Biotechnology; Livsmedelsteknik; Food and drink technology; bacteriocin purification.; inhibitory activity; Bacteriocin; antimicrobial protein;

   Sammanfattning : Development and optimization of the production of lactic acid bacteria (LAB) and their attendant 'natural' inhibitors as biopreservatives to control undesirable bacteria currently remains a primary focus of several laboratories involved in research concerning food safety and quality. Strategies utilized to study incorporation of biopreservatives into food include either direct use of LAB-strains or use of a biopreservative preparation in the form of previously fermented product or use of semipurified, purified, or chemically synthesized bacteriocins.

7. 45. Antimicrobial Resistance and Production of Extended Spectrum Beta-Lactamases in Enterobacteriaceae from Birds in Bangladesh

   Författare :Badrul Hasan; Björn Olsen; Åsa Melhus; Yvonne Agersø; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antimicrobial Resistance; ESBL; CTX-M; NDM; Poultry; Wild birds; E. coli; Bangladesh; Enterobacteriaceae; Antibiotics; Epidemiology; Epidemiologi; Mikrobiologi; Microbiology; Medical Science; Medicinsk vetenskap;

   Sammanfattning : The dissemination of members of the Enterobacteriaceae family with extended spectrum beta-lactamases (ESBLs) and metallo-beta-lactamases (MBLs) has become a global concern. ESBLs and MBLs have been reported in humans, domestic animals, wildlife and the environment, and their isolation frequencies are increasing rapidly worldwide. LÄS MER
