  2. 41. Wild rodents as carriers of potential pathogens to pigs, chickens and humans : with special emphasis on Brachyspira spp. and Yersinia enterocolitica

    Author : Annette Backhans; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The aim of this thesis was to investigate the specific risks that rodents constitute for proliferation of pathogens and transmission of those to farm animals, and indirectly to humans. Rodents were captured in pig and chicken flocks, in wastewater treatment plants and other urban environments. READ MORE

  4. 42. Perturbation of the epithelial barrier by enteric pathogens

    Author : Farideh Tafazoli; Magnusson Karl-Eric; Hakon Leffler; Linköpings universitet; []
    Keywords : enteric pathogens: signal transduction; barrier function; MEDICINE; MEDICIN;

    Abstract : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. READ MORE

  5. 43. Structure and host-receptor recognition studies of Gram-negative bacterial fimbriae assembled via the chaperone/Usher Pathway

    Author : Saumendra Prasad Roy; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Enterotoxigenic E. coli (ETEC), enteroaggregative E. coli (EAEC), and Yersinia enterocolitica (YE) are the principle etiological agents of acute and persistent diarrhea worldwide including resource-poor and industrialized regions. READ MORE

  6. 44. Studies on Polysaccharides from some Gram-Negative Bacteria

    Author : Kurt Samuelsson; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteria; chemical methods; food infections; polysaccharides; salmonella; Information Systems; Informatik;

    Abstract : In this survey structural studies on some polysaccharides isolated from the families of Enterobachteriaceae (Klebsiella and Salmonella) and Parvobacteriaceae (Yersinia) will be discussed. The occurence of some rare or not earlier reported deoxysugars is demonstrated, namely, 6-deoxy-D-manno-heptose, 3-deoxy-L-glycero-pentulosonic acid and five of the isomers of 3,6-dideoxy-hexoses.
