Between August and October 2000, a cross-sectional study was conducted in smallholder dairy farms in Mbale District, Uganda to assess the prevalence of ticks and tick-borne diseases under different grazing systems and agro-ecological zones and understand the circumstances under which farmers operated. A questionnaire was administered to obtain information on dairy farm circumstances and practic...

Climatic changes are projected to alter the abundance, dynamics, and geographical distribution of many vectorborne diseases in human populations. Tick-borne diseases such as Lyme disease and tick-borne encephalitis (TBE) are a growing concern in northern Europe and the United States. The impact of a future climate change on the transmission of tick-borne diseases is not known. To make such assu...

Canine tick-borne pathogens such as Ehrlichia canis and Hepatozoon canis are widespread in the Mediterranean basin but have never been reported or investigated in Cyprus. We describe herein the presence of canine tick-borne pathogens in three dogs with clinical signs compatible with vector-borne diseases from Paphos area of Cyprus. Molecular and phylogenetic analysis revealed the presence of E....

Immunological interaction at the tick host interface involves both innate and acquired host defenses against infestation and Immunomodulatory countermeasures by thetick. Acquired resistance to tick infestation involves humoral and cellular immlmoregulatory effector pathways. Tick-borne disease-causing agentspr exploit tick suppression of host defenses during transmission and initiation of infec...

The importance of tick-borne diseases is increasing all over the world, including Turkey. Global warming, environmental and ecological changes and the existence of suitable habitats increase the impact of ticks and result in frequent emergence or re-emergence of tick-borne diseases (TBDs) with zoonotic characteristics. In Turkey, almost 19 TBDs have been reported in animals and men, involving f...

♦ Personal protective measures, such as using insect repellent, wearing longsleeved shirts and long pants while outdoors, and avoiding tick and mosquito habitat, reduce the risk of vector-borne diseases. Vector-borne Diseases in Hennepin County Key Findings Introduction This Epidemiology Update summarizes vector-borne disease cases and trends in Hennepin County. This issue is one in a series of...

The risk of tick-borne encephalitis virus (TBEV) infection after a tick bite remains largely unknown. To address this, we investigated the presence of TBEV in ticks detached from humans in an attempt to relate viral copy number, TBEV subtype, and tick feeding time with the serological and clinical response of the tick-bitten participants. Ticks, blood samples, and questionnaires were collected ...

TBEV (Flaviviridae, Flavivirus) is an etiologic agent of tick-borne encephalitis (TBE), the most important arboviral human infection involving the central nervous system. The disease is endemic in a zone extending from central and eastern Europe to Siberia and Japan, and corresponds to the distribution of the ixodid ticks, which act both as the vectors and reservoir of TBEV. Humans acquire infe...

BACKGROUND AND AIMS Ticks are highly susceptible to global environmental and socio-economical changes. Several tick-borne pathogens have been reported in new geographical regions while new species, strains or genetic variants of tick-borne microorganisms are continually being detected. However, tick-borne pathogens are still poorly understood, and it is estimated that half of all human tick-bor...
