  2. 1. Development and evaluation of a subunit DIVA vaccine against bluetongue virus serotype 8 in cattle

    Author : Jenna Anderson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Bluetongue virus (BTV) causes the primarily vector-borne bluetongue disease of ruminants, which poses a permanent threat to Europe since new serotypes and strains are frequently introduced. Vaccination of cattle is essential to control BTV outbreaks. READ MORE

  4. 2. Molecular analysis of transcription factors in uropathogenic E. coli adhesin operons

    Author : Stina Lindberg; Bernt Eric Uhlin; Åsa Sjöling; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; UPEC; E. coli; F1C; P fimbriae; cross-talk; FocB; PapB; crystal structure; OMVs; Medical microbiology; Medicinsk mikrobiologi; molekylärbiologi; Molecular Biology;

    Abstract : The main causative agent of human urinary tract infections is the uropathogenic Escherichia coli (UPEC) pathotype. It may cause disease due to its ability to express a number of bacterial virulence factors. Fimbrial adhesins are particularly important for the initial establishment of infection in the urinary tract. READ MORE

  5. 3. Antibiotic interactions and selection for resistance in biofilms

    Author : Po-Cheng Tang; Dan I. Andersson; Karin Hjort; Mark Webber; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotics; Mikrobiologi; Microbiology;

    Abstract : The challenges posed by antibiotic-resistant bacteria in treating infections, particularly those associated with biofilms, require a deeper understanding of this lifestyle and its connection to resistance selection. Additionally, gaining insights into drug interactions is crucial for enhancing combination treatment efficacy and mitigating resistance development. READ MORE

  6. 4. The role of P fimbriae for Escherichia coli establishment and mucosal inflammation in the human urinary tract

    Author : Björn Wullt; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; Microbiology; asymptomatic bacteriuria; urinary tract infections; deliberate colonization; E. coli 83972; P-fimbriae; Mucosal host response; IL-6; IL-8; neutrophils; regulation.; GFP; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Bacterial adhesion to the bladder mucosa is a critical step for the establishment of Escherichia coli bacteriuria. The P-fimbriae, encoded by the pap gene cluster, are considered as virulence factors but the mechanisms have been debated. This study defined the roles for P fimbriation during the early colonization of the human urinary tract. READ MORE

  7. 5. Role of TLR4 in Escherichia coli urinary tract infection

    Author : Patrik Samuelsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; mycology; Mikrobiologi; bakteriologi; serologi; transplantation; Microbiology; virology; bacteriology; Immunologi; serology; Immunology; Pathogen; Mucosa; P-fimbriae; Toll like receptor;

    Abstract : In this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. READ MORE
