   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oral Microbiology; Oral Biofilms; Saliva; Salivary mucin MUC5B; Streptococcus; Actinomyces;

   Abstract : This thesis investigates responses to external cues in oral bacteria on a molecular level. Paper I maps Ser/Thr/Tyr phosphorylated proteins in relation to the general proteome in an oral commensal streptococcus (Streptococcus gordonii DL1). READ MORE

5. 3. Porphyrins and heme in microorganisms : Porphyrin content and its relation to phototherapy and antimicrobial treatments in vivo and in vitro

   Author : Jonas Fyrestam; Conny Östman; Jonas Bergquist; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Porphyrins; heme; phototherapy; antimicrobial resistance; singlet oxygen; photosensitizer; bacteria; HPLC-MS MS; oral bacteria; Aggregatibacter actinomycetemcomitans; Porphyromonas gingivalis; Escherichia coli; Analytical Chemistry; analytisk kemi;

   Abstract : One of the greatest threats to human health is increasing antimicrobial resistance among pathogens, and finding alternatives for treatment of bacterial infections is of highest importance together with a more controlled use of antibiotics. Porphyrins and heme have both been shown to be a promising class of compounds for inactivation of bacteria; porphyrins by their excellent properties to act as a photosensitizer, and heme by its importance as an iron source during a bacterial infection in vertebrates.

6. 4. Porphyrins and phototherapy of oral bacteria

   Author : Nadja Bjurshammar; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : In the mid-1990s researchers became interesting in blue light-based therapies using light-emitting diodes (LED) light. Blue light therapy has been successfully used in treatment of acne, as well as shown wound healing effects. It has also shown significant antibacterial effects, especially on black-pigmented bacteria. READ MORE

7. 5. Lactobacillus characterization and effects on oral biofilm composition

   Author : Nelly Romani Vestman; Ingegerd Johansson; Jukka Meurman; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lactobacillus; L. gasseri; probiotic traits; oral biofilm; breastfeeding; oral microbiota; odontologi; Odontology;

   Abstract : The human body is home for millions of bacteria. The largest microbial community is located in the gastro-intestinal (GI) tract, including the oral cavity with >700 identified taxa. Lactobacillus, which is normal inhabitant of the GI tract, contributes to health by possible biofilm and immune modulation. READ MORE
