1. Studies of Spotted Fever Rickettsia - Distribution, Detection, Diagnosis and Clinical Context : With a Focus on Vectors and Patients in Sweden
Sammanfattning : The spotted fever rickettsia, Rickettsia helvetica, is an endemic tick-borne bacteria in Sweden. It causes infections in humans, manifested as aneruptive fever, headache, arthralgia and myalgia, and sometimes an inoculation eschar or a rash. There have also been two known cases of human infections with R. felis in Sweden. LÄS MER
2. Rickettsia helvetica; Detection in arthropods and human tissues and its relation to clinical disease
Sammanfattning : 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.

3. Causes of Substitution Frequency Variation in Pathogenic Bacteria
Sammanfattning : Estimating substitution frequencies at sites that influence (Ka) and do not influence (Ks) the amino acid sequence is important for understanding the dynamics of molecular sequence evolution and the selective pressures that have shaped genetic variation. The aim of this work was to gain a deeper understanding of the driving forces of substitution frequency variation in human pathogens. LÄS MER
4. Spotted Fever Rickettsioses in Sweden : Aspects of Epidemiology, Clinical Manifestations and Co-infections
Sammanfattning : The spotted fever group rickettsiae are emerging diseases. They cause damage in their hosts by invading the endothelium in small to medium-sized blood vessels, which results in vasculitis that can cause clinical manifestations from most organs. LÄS MER
5. Mapping the Rickettsia prowazekii genome
Sammanfattning : Rickettsia prowazekii is a member of alpha proteobacteria and the etiologic agent of epidemictyphus. Besides its pathogenicity as an obligate intracellular parasite it has been considered as amodel organism in a variety of studies.We have established a collection of overlapping clones, covering nearly the complete R.prowazekii genome.
