  2. 1. Spotted Fever Rickettsioses in Sweden : Aspects of Epidemiology, Clinical Manifestations and Co-infections

    Author : Anders Lindblom; Kenneth Nilsson; Björn Olsen; Björn Herrmann; Clas Ahlm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rickettsia helvetica; Rickettsia felis; co-infection; erythema migrans; meningitis; serology; PCR; western blot; Infektionssjukdomar; Infectious Diseases;

    Abstract : 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. READ MORE

  4. 2. 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.

  5. 3. Studies of Spotted Fever Rickettsia - Distribution, Detection, Diagnosis and Clinical Context : With a Focus on Vectors and Patients in Sweden

    Author : Katarina Wallménius; Kenneth Nilsson; Thomas Jaenson; Björn Olsen; Fredrik Elgh; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tick-borne infections; co-infections; ticks; Ixodes ricinus; zoonosis; Rickettsia helvetica; migrating birds; Bell’s pares; erythema migrans; Rickettsia aeschlimannii; sudden deafness; facial nerve paralysis; Hyalomma marginatum; Rickettsia africae; western blot; PCR; serology; Clinical Bacteriology; Klinisk bakteriologi;

    Abstract : 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. READ MORE

  6. 4. Epidemiological and Bacteriological Aspects of Spotted Fever Rickettsioses in Humans, Vectors and Mammals in Sweden

    Author : Karin Elfving; Kenneth Nilsson; Eva Hjelm; Björn Olsen; Tomas Bergström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rickettsia helvetica; ticks; cultivation; serology; polymerase chain reaction PCR ; DNA sequencing; western blot; electron microscopy; meningitis; seroprevalence;

    Abstract : Rickettsiae are obligate intracellular gram-negative bacteria transmitted by arthropod vectors. Rickettsiae sometimes cause disease in humans, typically with high fever, headache and occasionally an eschar.In Sweden, Rickettsia helvetica, belonging to the spotted fever group, is the only tick-transmitted rickettsia found free in nature.

  7. 5. Dispersal of ticks and their microorganisms by African-Western Palaearctic migratory birds

    Author : Tove Hoffman; Björn Olsen; Åke Lundkvist; Kenneth Nilsson; Johan Normark; Uppsala universitet; []
    Keywords : African-Western Palaearctic; migratory birds; Ixodidae; Hyalomma rufipes; Ixodes; Alkhurma hemorrhagic fever virus; Anaplasma phagocytophilum; Francisella; Midichloria; Rickettsia aeschlimannii; PCR; microfluidic qPCR; metagenomics; Biologi; Biology;

    Abstract : In Europe, tick-borne diseases are the most widespread and common vector-borne diseases and their geographical distribution is increasing. The dispersal of ticks depends on the movements of their vertebrate hosts. Avian hosts are more likely to be involved in long-distance range expansion of ticks due to their migration pattern.
