2. 1. Group B streptococci and other neonatal infections

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

   Abstract : 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. READ MORE

4. 2. PROTEIN VACCINE AGAINST NEONATAL GROUP B STREPTOCOCCAL INFECTION Immunization experiments in animals and a serological study in humans

   Author : Charlotte U Larsson; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; bacteriology; Microbiology; virologi; mykologi; neonatal infection; human antibody; intranasal; vaccine; cholera toxin B subunit; Rib; α; Group B streptococcus; surface protein; Mikrobiologi; virology;

   Abstract : Infection with group B streptococcus (GBS), an encapsulated bacterium, is an important cause of neonatal morbidity and mortality. Capsular polysaccharides and cell surface proteins of GBS are candidate antigens for development of a human GBS vaccine. Proteins have many advantages as vaccine antigens. READ MORE

5. 3. Neonatal invasive infections with focus on Group B streptococci

   Author : Margrét Johansson Gudjónsdóttir; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neonatal sepsis; Group B streptococci; Virulence factors;

   Abstract : Invasive infections affect neonates with the risk of severe morbidity and death, and Streptococcus agalactiae (Group B streptococcus, GBS) remains one of the most common pathogens. The aim of this thesis was to assess infections among neonates and infants, focusing on GBS to better understand prevention and treatment. READ MORE

6. 4. Molecular epidemiology of streptococcus agalactiae : mobile elements as genetic markers

   Author : Shi-Lu Luan; Mari Norgren; Barbara Spellerberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus agalactiae; group II intron GBSi1 ; multilocus sequence typing; capsular serotype; population structure; Clinical bacteriology; Klinisk bakteriologi;

   Abstract : Streptococcus agalactiae, also designated group B streptococcus (GBS), is a Gram-positive coccus, and it is an important pathogen that causes invasive disease in neonates, pregnant adults, and non-pregnant adults with predisposing conditions. The group II intron GBSi1 is one of the major mobile genetic elements identified in S. agalactiae. READ MORE

7. 5. Streptococcal protein Rib and related proteins: a family of repetitive surface proteins that elicit protective immunity

   Author : Margaretha Stålhammar-Carlemalm; Institutionen för laboratoriemedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; cross-protection; epithelial cell adhesion; protective immunity; vaccination; surface proteins; Group B streptococcus; Streptococcus pyogenes; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Abstract : ABSTRACT Streptococci constitute a heterogeneous group of Gram-positive bacteria, divided into different serological groups on the basis of antigenic differences in a cell wall-associated carbohydrate. This thesis describes related surface proteins expressed by bacteria in two of these groups, the group B streptococcus (GBS) and the group A streptococcus (GAS). READ MORE
