2. 1. Exotoxins of Aggregatibacter actinomycetemcomitans and periodontal attachment loss in adolescents

   Author : Carola Höglund Åberg; Anders Johansson; Rolf Claesson; Dorte Haubek; Andrea Mombelli; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; periodontal attachment loss; JP2 genotype; non-JP2 genotype; LtxA; Cdt; Infectious Diseases; infektionssjukdomar;

   Abstract : Aggregatibacter actinomycetemcomitans is an oral bacterium that is mainly associated with aggressive forms of periodontitis, which most often starts at an early age. Amongst the virulence factors of A. READ MORE

4. 2. Invasive group A streptococcal infection : host and pathogen interactions

   Author : Björn K G Eriksson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Group A streptococci; invasive infections; erysipelas; Streptococcal Toxic Shock Syndrome STSS ; epidemiology; M1 serotype streptococcal pyrogenic exotoxins Spe ; SpeA; toxin neutralization; opsonization;

   Abstract : Invasive group A streptococcal (GAS) infections were studied in 229 patients with a clinical diagnosis of erysipelas and 151 patients with GAS bacteremia, respectively. Beta-hemolytic streptococci were identified in about a third of the erysipelas patients, mostly group A, whereas group G streptococci were identified in about half as many episodes. READ MORE

5. 3. Survival of infectious agents and detection of their resistance and virulence factors

   Author : Eva Tano; Åsa Melhus; Jan Sjölin; Marie-Louise Danielsson-Tham; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transportation system; swab; polymicrobial samples; Neisseria gonorrhoeae; bacteremia; exotoxins; Staphylococcus aureus; TSST-1; silver; silver resistance; wound dressing; sil genes; laundry; tumble drying; bacterial decontamination;

   Abstract : In the first study, three different transport systems for bacteria were evaluated. The CLSI M40-A guideline was used to monitor the maintenance of both mono- and polymicrobial samples during a simulated transportation at room temperature that lasted 0-48 h. READ MORE

6. 4. Process Analytical Tools for the Monitoring and Characterization of Bacterial Toxins

   Author : Martin Hedström; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; protein degradation; mass spectrometry; Bacterial toxins; Biosensor;

   Abstract : In the era of proteomics, glycomics and ultimately metabolomics, with constantly increasing knowledge regarding the human biosystem, the number of specialized therapeutic agents which will be developed against different diseases is predicted to be on the upswing. An increasing portion of these new drugs will, according to recent predictions (Labrou, 2003), be of proteinaceous origin produced according to biotechnological standards. READ MORE

7. 5. Host-pathogen interactions in invasive Staphylococcus aureus infections

   Author : Srikanth Mairpady Shambat; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Staphylococcus aureus is a versatile human pathogen causing a wide range of diseases from uncomplicated skin and soft tissue infections to life-threatening invasive diseases like endocarditis, bacteremia, necrotizing pneumonia, and fasciitis. The pathogen has become increasingly resistant to -lactam antibiotics, and of special concern is the rise in community- acquired (CA)-MRSA strains, as specific CA-MRSA clones have been associated with highly aggressive infections.
