  1. 1. Influence of host and bacterial factors during Neisseria meningitidis colonization

    Författare :Sara Sigurlásdóttir; Ann-Beth Jonsson; Ute Römling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Colonization; Host-bacteria interactions; Lactate; Biofilms; Polynucleotide phosphorylase; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The human-restricted pathogen Neisseria meningitidis is a major cause of bacterial meningitis and sepsis worldwide. Colonization of the mucosal layer in the upper respiratory tract is essential to establish an asymptomatic carrier state and invasive disease. N. LÄS MER

  3. 2. Epidemiology of Enterococci with Acquired Resistance to Antibiotics in Sweden : Special emphasis on Ampicillin and Vancomycin

    Författare :Erik Torell; Mats Kallin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; Antimicrobial resistance; enterococci; epidemiology in Sweden; intra-hospital spread; shedding; risk-factors; infection; colonization; virulence factors; ARE; VRE; Php; PFGE; esp; gyrA; parC; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar; infektionssjukdomar; Infectious Diseases;

    Sammanfattning : The first hospital outbreak of vancomycin-resistant enterococci (VRE) and carriage rates of VRE and ampicillin-resistant enterococci (ARE) in Sweden were investigated. Clonal relationships and mutations in fluoroquinolone resistance determining regions among ARE collected nation-wide were studied. LÄS MER

  4. 3. The Colonization Strategies of Nontypeable Haemophilus influenzae - Bacterial Colonization Factors and Vaccine Development

    Författare :Farshid Jalalvand; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ABC-transporter; bacterial colonization; Haemophilus influenzae; Haemophilus Protein F; laminin; NTHi; pathogenesis; vaccine; virulence; vitronectin.;

    Sammanfattning : Nontypeable Haemophilus influenzae (NTHi) is a remarkably proficient colonizer of the human respiratory tract. The aim of this thesis has been to characterize currently known, and identify novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity.

  5. 4. Studies on the Expression and Regulation of Enterotoxins and Colonization Factors in Enterotoxigenic Escherichia coli (ETEC)

    Författare :Matilda Nicklasson; Göteborgs universitet; []
    Nyckelord :ETEC; heat-stable enterotoxin; heat-labile enterotoxin; colonization factors; CS5; CS6; virulence gene expression; in vivo and in vitro; genetic variability;

    Sammanfattning : Enterotoxigenic Escherichia coli (ETEC) is one of the most common causes of acute watery diarrhoea in developing countries, particularly among local children less than five years and is also the most common cause of diarrhoea in travellers to ETEC endemic areas. The infection is transmitted by ingestion of contaminated food and water and the disease is established in the small intestine. LÄS MER

  7. 5. Antibiotic resistance and pathogenesis of Streptococci with focus on Group A Streptococci

    Författare :Feiruz Alamiri; Malmö Experimentell infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotika resistens; Bröstmjölk; Luftvägsinfektioner; Biofilm bildning; Internalisering; Persistens; HAMLET; Streptokocker; kolonisering; Streptococcus pneumoniae; biofilm formation; Internalisation; Persistence; Antibiotic resistance; Streptococcus pyogenes; Streptococcus agalactiae; HAMLET; Breast milk; Proteome; Virulence factors; Colonization;

    Sammanfattning : Multi-drug resistant (MDR) infections remain the leading cause of death worldwide. MDR infections caused by Streptococcus pneumoniae (Spn), Streptococcus pyogenes (GAS) and Streptococcus agalactiae (GBS) are considered global threats to human health due to increased spread of antibiotic resistance and limited treatment options.
