2. 21. Rickettsia helvetica; Detection in arthropods and human tissues and its relation to clinical disease

   Author : Kenneth Nilsson; Björn Olsen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; rickettsia; spotted fever; tick; PCR; myocarditis; sarcoidois; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar; Infektionssjukdomar; Infectious Diseases;

   Abstract : A relation between R. helvetica and perimyocarditis was, in two young men who died of sudden cardiac death during exercise in 1997, suggested by a seminested PCR, for three different genes, sequencing of the amplified products, documentation of a seroresponse and histopathologic changes in accordance with rickettsioses.

4. 22. Stability of bacterial DNA in relation to microbial detection in teeth

   Author : Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-bound DNA; cell-death; dentine; DNA binding affinity; DNA decomposition; DNA preservation; extracellular DNA; hydroxyapatite; PCR; polymerase chain reaction; odontologi; Odontology;

   Abstract : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. READ MORE

5. 23. The ubiquity and type diversity of papillomaviruses in normal skin

   Author : Annika Antonsson; Malmö Klinisk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; skin phylogeny; HPV prevalence; HPV type detrmination; PCR; human papillomavirus; HPV;

   Abstract : Papillomaviruses are a diverse, epitheliotropic group of viruses. Some genotypes are the main cause of anogenital cancer in humans; others can induce skin lesions. In order to investigate the occurrence of subclinical skin infections with human papillomavirus (HPV), a pair of degenerate primers (FAP59/64) was designed. READ MORE

6. 24. Development of novel molecular methods for Campylobacter species and for Helicobacter pylori

   Author : Kristina Blom; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Campylobacter; Helicobacter pylori; PCR; mRNA; hybridization; flow cytometry; HpaA; urease; NAP;

   Abstract : Background and Aim: Different Campylobacter species and Helicobacter pylori are common causes of gastrointestinal infections that may result in diarrhea and chronic gastritis, respectively. The overall aim of this thesis was to develop novel methods for identification, differentiation and characterization of these bacteria. READ MORE

7. 25. Molecular analysis of the oral microbiota of dental diseases

   Author : Eleni Kanasi; Sirkka Asikainen; Anne CR Tanner; Ingegerd Johansson; Gunnar Dahlén; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; early childhood caries; early periodontitis; 16S rDNA cloning and sequencing; whole genomic DNA probes; oligonucleotide DNA probes; PCR; diversity; molecular; aggregatibacter actinomycetemcomitans; serotypes; Oral microbiology; Oral mikrobiologi;

   Abstract : Traditionally, bacterial culture has been used for bacterial detection, allowing study of living microorganisms. Molecular methods are rapid and allow simultaneous identification of numerous species and uncultivated phylotypes. READ MORE
