  2. 6. Extended-Spectrum Beta-Lactamase-Producing Enterobacteriaceae: Epidemiology, Risk Factors, and Duration of Carriage

    Author : Johan Tham; Enheten för infektionssjukdomar; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extended-spectrum beta-lactamase; ESBL; risk factors; resistant bacteria; E. coli; Enterobacteriaceae; antibiotics; food;

    Abstract : In human medicine, the most important family of bacteria is Enterobacteriaceae, which includes genera and species that cause well-defined diseases and also nosocomial infections. These bacteria can give rise to numerous infections such as septicaemia and urinary tract infections. READ MORE

  4. 7. Epidemiology of extended-spectrum β-lactamase-producing Escherichia coli

    Author : Sofia Ny; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Extended-Spectrum β-Lactamase and plasmid mediated AmpC (ESBL/pAmpC)-producing Escherichia coli (E. coli) has during the last decades emerged worldwide and is now an increasing problem in both human and animal health. READ MORE

  5. 8. Long-term molecular epidemiology of extended-spectrum β-lactamase producing Escherichia coli in a low-endemic setting

    Author : Anna Fagerström; Bo Söderquist; Paula Mölling; Martin Sundqvist; Katarina Persson; Linus Sandegren; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Escherichia coli; extended-spectrum β-lactamase; whole genome sequencing; plasmids; hybrid assembly; environment; IncI1; ST131;

    Abstract : Escherichia coli is a commensal inhabitant in the gastro-intestinal tract of humans and animals but it is also the most common bacterial species causing urinary tract infection, which ranges in severity from distal cystitis to urosepsis and septic shock. During the past decades, the prevalence of antibiotic resistant E. READ MORE

  6. 9. Species specific susceptibility testing for ß-lactam antibiotics. With special reference to staphylococci

    Author : Ann Cathrine Petersson; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; Mikrobiologi; virology; bacteriology; beta-lactamase; staphylococcus; methicillin resistance; Microbiology; mecA susceptibility testing; virologi; mykologi;

    Abstract : The main objective of this thesis was to identify methods for the detection of ß-lactam resistance in staphylococci, bacteria often causing nosocomial infections. Detection of ß-lactam resistance in these species is difficult due to strong regulation of genes encoding for the two main resistance mechanisms, ß-lactamase production and the penicillin-binding protein (PBP) 2?.

  7. 10. Experimental acute otitis media : aspects on treatment, protection and structural changes

    Author : Eva Westman; Ann Hermansson; Sten Hellström; Åsa Melhus; Bengt Carlsöö; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; acute otitis media; penicillins; rat; treatment; protection; beta-lactamase; Moraxella catarrhalis; Haemophilus influenzae; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : Acute otitis media (AOM) is a common disease in childhood and is one of the most common causes for outpatient antibiotic treatment. The major aetiological agents of AOM have varied over the decades. Now the three most common pathogens are Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. READ MORE
