In Europe, ixodid ticks are important arthropod vectors of human and animal pathogens, but comprehensive studies of the prevalence of all relevant pathogens in Central Europe are scarce. As a result of ecological changes, the incidences of tick-borne infections are expected to increase. In this study, 1,394 nymphal and adult Ixodes ricinus ticks sampled monthly during the active season from 33 ...

Relevance . The Sverdlovsk region is a highly endemic territory for infections transmitted by ixodic ticks. possibilities of laboratory diagnostics tick–borne in the routine practice clinician today are limited mainly testing blood serum antibodies to tick-borne encephalitis virus (TBE virus) and Lyme disease (LD) pathogens – Borrelia burgdorferi sensu lato complex, therefore, among currently T...

Infections with vector-borne pathogens are a major source of emerging diseases. The ability of vectors to bridge spatial and ecologic gaps between animals and humans increases opportunities for emergence. Small adaptations of a pathogen to a vector can have profound effects on the rate of transmission to humans.

Tick-borne spirochetes include borreliae that cause Lyme disease and relapsing fever in humans. They survive in a triangle of parasitic interactions between the spirochete and its vertebrate host, the spirochete and its tick vector, and the host and the tick. Until recently, the significance of vector-host interactions in the transmission of arthropod-borne disease agents has been overlooked. H...

Lyme disease is one of the most frequent tick-borne diseases worldwide, it can be multi-systemic and insidious, in particular when it shows a chronic course. In recent years co-infections represent an emerging issue in Lyme disease spectrum because in addition to Borrelia burgdorferi sl many other potential pathogens may be transmitted by hard ticks Ixodes species. The main co-infections found ...

The article presents an overview of diagnostics of tick-borne diseases in Poland, which form one of the most prevalent group of occupational illnesses in the Polish area. This is a current issue due to a constantly growing number of tick-borne infections, i.e., Lyme borreliosis, tick-borne encephalitis, tularemia, Q fever, human granulocytic anaplasmosis and babesiosis. The scale of the problem...

Tick-borne pathogens can cause serious problems in grazing cattle. However, little information is available on tick-mediated diseases in cattle grazing on mountains. Thus, this study aimed to understand the potential problems related to tick-borne diseases in grazing cattle through the investigation of prevalent tick-transmitted infections, and their associated hematological changes, in terms o...

BACKGROUND The majority of vector-borne infections occur in the tropics, including Africa, but molecular eco-epidemiological studies are seldom reported from these regions. In particular, most previously published data on ticks in Ethiopia focus on species distribution, and only a few molecular studies on the occurrence of tick-borne pathogens or on ecological factors influencing these. The pre...

Lyme disease and Tick-Borne Encephalitis (TBE) are two emergent tick-borne diseases transmitted by the widely distributed European tick Ixodes ricinus. The life cycle of the vector and the number of hosts involved requires the development of complex models which consider different routes of pathogen transmission including those occurring between ticks that co-feed on the same host. Hence, we co...

Relapsing fever is a group of conditions that is characterized by recurrent febrile episodes interspaced with periods of no symptoms at all. They are arthropod-borne spirochetal infections of the Borrellia genus and occur in two main forms: tick-borne and louse-borne. Tick-borne relapsing fever is a zoonosis that is found worldwide. The louse-borne relapsing fever is caused by B. recurrentis, a...
