   Sammanfattning : K. pneumoniae is recognized as a common opportunistic pathogen. Numerous reports have been published worldwide on outbreaks in different healthcare settings. K. LÄS MER

3. 17. Ecological aspects of antimicrobial susceptibility of anaerobic bacteria in Nicaragua

   Författare :Mercedes Cáceres; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Antimicrobial susceptibility; normal flora; anaerobic infections; B-lactamase; enterotoxigenic B. fragilis;

   Sammanfattning : Anaerobic bacteria are the predominant constituents of the normal flora on the skin and the mucous membranes of the human body. They may also act as potent pathogens in a variety of endogenous infections. Antimicrobial resistance is an increasing problem with anaerobic and aerobic bacteria. Different mechanisms for such resistance are known. LÄS MER

4. 18. Haemophilus influenzae – typing, epidemiology and beta-lactam resistance

   Författare :Viktor Månsson; Malmö Klinisk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; benzylpenicillin; beta-lactam resistance; beta-lactams; BLNAR; capsule typing; clonal; Haemophiilus influenzae; Hib; MALDI-TOF MS; MLST; NTHi; serotyping; virulence; epidemiology;

   Sammanfattning : Haemophilus influenzae is a common cause of respiratory tract infections such as acute otitis media (AOM), exacerbations of chronic obstructive pulmonary disease (COPD) and pneumonia. The species is subdivided into encapsulated and non-encapsulated strains, designated type a-f and nontypeable H. influenzae (NTHi), respectively. LÄS MER

5. 19. Ribosomes and subunits from Escherichia coli studied by asymmetrical flow field-flow fractionation

   Författare :Mikael Nilsson; Centrum för analys och syntes; []

   Sammanfattning : In this thesis asymmetrical flow field-flow fractionation (FFF) separations of ribosomes and subunits have been studied. Ribosomal material was prepared from Escherichia coli (E. coli) cells and analyzed by the size separation technique. LÄS MER

7. 20. Uropathogenic Esherichia coli, multidrug-resistance and induction of host defense mechanisms

   Författare :Isak Demirel; Katarina Persson; Robert Kruse; Mirjana Poljakovic; Gabriela Godaly; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract infection; uropathogenic Escherichia coli; suppressor of cytokine signalling 3; nitric oxide; cytokines; extended-spectrum beta-lactamases; filamentation; IL-6; Biomedicin; Biomedicine;

   Sammanfattning : Uropathogenic Escherichia coli (UPEC) is the primary cause of urinary tract infection (UTI), which is one of the most common infections in humans. UPEC strains have acquired successful strategies to subvert the host defense and antibiotics to persist in the urinary tract. LÄS MER
