  1. 1. Ticks and Tick-borne Encephalitis Virus : From Nature to Infection

    Författare :Naveed Asghar; Magnus Johansson; Patrik Dinnétz; Travis Taylor; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Co-occurrence; Environmental factors; Flavivirus; Ixodes ricinus; Natural foci; Non-coding region; Poly A tract; Quasispecies; Questing ticks; Scandinavia; Tick-borne encephalitis virus; Vegetation.; Environmental Studies; Miljövetenskapliga studier;

    Sammanfattning : Vector-borne diseases are an increasing global threat to humans due to climate changes, elevating the risk of infections transmitted by mosquitos, ticks, and other arthropod vectors. Ixodes ricinus, a common tick in Europe, transmits dangerous tick-borne pathogens to humans. LÄS MER

  3. 2. Epidemiological and Bacteriological Aspects of Spotted Fever Rickettsioses in Humans, Vectors and Mammals in Sweden

    Författare :Karin Elfving; Kenneth Nilsson; Eva Hjelm; Björn Olsen; Tomas Bergström; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  4. 3. LYME BORRELIOSIS Detection and identification of the infecting genotype

    Författare :Katharina Ornstein; Sektion III; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parasitologi människa och djur ; Parasitology human and animal ; Infektioner; Infections; PCR; genospecies; Lyme borreliosis; Borrelia burgdorferi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Lyme borreliosis is caused by the spirochete Borrelia burgdorferi sensu lato, a bacterium with a parasitic life-style, which is transmitted between hosts by the Ixodes tick-vector. Humans will incidentally become infected. The resulting illness can involve the skin, nervous system, joints and heart. LÄS MER

  5. 4. Epidemiology and clinical manifestations of Lyme borreliosis

    Författare :Johan Berglund; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ELISA.; Western blot; Arthritis; Ixodes ricinus; Ticks; Population based; Sweden; Prevention; Surveillance; Erythema migrans; Neuroborreliosis; Lyme arthritis; Epidemiology; Lyme borreliosis; Borrelia burgdorferi; Social medicine; Socialmedicin; samhällsmedicin; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Epidemiological and clinical characteristics of Lyme borreliosis (LB) in Sweden are described through a one year surveillance-study. The findings differed only marginally when compared to studies from the United States indicating similar clinical presentation of the disease. Incidence was 69/100. LÄS MER

  7. 5. Epidemiological aspects of tick borne diseases with focus on risk and prevention

    Författare :Louise Stjernberg; Pia Forsberg; Allmänmedicin och samhällsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiologi; epidemiology; Folkhälsa; Public health; lyme borreliosis; prevention; risk; ticks; tick borne diseases; epidemiologi; epidemiology; Folkhälsa; Public health; lyme borreliosis; prevention; risk; ticks; tick borne diseases;

    Sammanfattning : The incidence and variety of diseases associated with ticks have increased world-wide and ticks are currently considered to be second only to mosquitoes as vectors of human infectious diseases in the world. In the northern hemisphere, Ixodes ricinus, the most common tick, transmits diseases caused by several infectious pathogens, including different types of bacteria, virus and protozoa. LÄS MER
