1. 1. Development of novel vaccine strains of Vibrio cholerae and studies on the role of serotype in epidemic spread of cholera

   Författare :Stefan Karlsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cholera; Vibrio cholerae; Serotype; Ogawa; Inaba; Hikojima; Vaccine; Immunogenicity; serotype switching; wbeT;

   Sammanfattning : Cholera, caused by bacterium Vibrio cholerae O1, is a severe diarrheal disease with an estimated 3-5 million cases and more than 140 000 deaths every year particularly affecting children under 5 years of age. It can be found all over the world and often causes cholera in places where access to clean water or proper sanitary facilities are limited or compromised. LÄS MER

3. 2. Respiratory Tract Infections: Aspects of Aetiology, Virulence, and Communicable Disease Control

   Författare :Jonas Ahl; Enheten för infektionssjukdomar; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus pneumoniae; day care center; communicable disease control intervention; eradication therapy; invasive pneumococcal disease; serotype 3; aetiology; ventilator-associated pneumonia;

   Sammanfattning : The paediatric nasopharyngeal flora is regarded as the largest reservoir for Streptococcus pneumoniae, and the carrier state is always antecedent to infection and a prerequisite for dispersion of these bacteria. Pneumococci are the predominant aetiology of bacterial respiratory tract infections and a major cause of morbidity and mortality, in the most severe cases due to invasive pneumococcal disease (IPD; mainly sepsis and meningitis).

4. 3. Host-parasite interaction in men with febrile urinary tract infection

   Författare :Peter Ulleryd; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; urinary tract infection; fever; male; Escherichia coli; serotype; virulence; PSA; prostate; prostatitis; TRUS; urography; cystoscopy; treatment; ciprofloxacin;

   Sammanfattning : In a retrospective study, Escherichia coli isolates from 88 men with symptomatic urinary tract infection (UTI) were analysed. A wide array of O:K:H serotypes commonly associated with acute pyelonephritis in women were identified. LÄS MER

5. 4. Group B streptococci and other neonatal infections

   Författare :Elisabet Persson; Göteborgs universitet; []
   Nyckelord :Neonatal infections; sepsis; incidence; ; Group B streptococcus; ; serotype; ; epidemiology; ; genotype; ; surface protein; ; antibiotic susceptibility;

   Sammanfattning : The main objectives of this thesis were to estimate the incidence and etiology of invasive infections in neonates and to characterize invasive strains of group B streptococci from a defined geographic area. All infants aged 0-120 days with a bacterial or fungal isolate from blood or CSF in the defined area were identified. LÄS MER

7. 5. Synthesis of oligosaccharides related to the capsular polysaccharides of Streptococcus pneumoniae serotype 9 and of Cryptococcus neoformans

   Författare :Marianne Alpe; Ulf Ellervik; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

   Sammanfattning : In the present investigation, synthesis of oligosaccharides corresponding to structural elements present in the capsular polysaccharides of Streptococcus pneumoniae and Cryptococcus neoformans has been achieved. The first two sections describe the synthesis of spacer-equipped oligosaccharides corresponding to structures from the CPS of Streptococcus pneumoniae serotypes 9N, 9A and 9L, the production of which involved synthetic challenges such as the construction of β-ManNAc and α-GlcA linkages.
