Disease relevance of Tick-Borne Diseases

• Anaplasma phagocytophilum causes human granulocytic ehrlichiosis, the second most common tick-borne disease in the United States. Mice are natural reservoirs for this bacterium and man is an inadvertent host [1].
• We could show that native and recombinant LipOspA induce monospecific immune sera able to passively transfer protection in SCID mice against experimental and tick-borne infection and disease [2].

High impact information on Tick-Borne Diseases

• A workshop of the European Union (EU) Concerted Action Project on the Integrated Control of Ticks and Tick-borne diseases (CA-ICTTD) recently assessed protective immune mechanisms to ticks and tick-borne diseases [3].
• STUDY DESIGN AND METHODS: A prototype peptide EIA was used to detect B. microti-specific antibodies in 15 sera taken before infection and 107 taken after infection from 59 individuals with known tick-borne infections previously confirmed by other methods [4].
• The discovery and use of arsenical solutions in dipping vats for treating cattle to protect them against ticks revolutionized tick and tick-borne disease control programmes [5].
• Simple analytical models of tick- and tsetse-borne diseases suggest that reducing the abundance of ticks, by treating cattle with pyrethroids for example, can have a variety of effects on tick-borne diseases [6].
• This indicates that the latter two species, vectors of 'exotic' tick-borne diseases, remain at low densities in Great Britain and Ireland. Retrospective information on exposure of the animals to different habitats and geographic regions was collected by questionnaire and subject to contingency table and logistic regression analysis [7].

Chemical compound and disease context of Tick-Borne Diseases

• Opening statement for the FAO Expert Consultation on Revision of Strategies for the Control of Ticks and Tick-borne Diseases [8].
• Bos taurus calves free from tick-borne diseases were prophylactically treated with oxytetracycline hydrochloride and phenamidine isothionate 40% (w/v) injections and infested twice with adult Rhipicephalus appendiculatus ticks [9].
• A bibliography on ticks and tick-borne diseases in the countries of the Benelux (1567-1978) [10].
• However, there are indications that deltamethrin can also reduce tick populations and the incidence of tick-borne diseases [11].
• Efficacy of imidocarb diproprionate and primaquine phosphate in the prevention of tick-borne disease in imported Hereford heifers in South Korea [12].

Gene context of Tick-Borne Diseases

• Forty-six cows were purchased from the western Cape Province in January 1984; 2 died from the tick-borne disease anaplasmosis in March and a labourer who helped butcher the carcasses became ill a few days later [13].
• Nine strains of Avalon virus were isolated from Ixodes uriae ticks collected in the Cape Sizun seabird reserve, Brittany, from 1979 to 1985, during a longitudinal study of consequences of tick-borne infections for kittiwakes (Rissa tridactyla) [14].
