Zoonotic tick-borne diseases are an increasing health burden in Europe and there is speculation that this is partly due to climate change affecting vector biology and disease transmission. Data on the vector tick Ixodes ricinus suggest that an extension of its northern and altitude range has been accompanied by an increased prevalence of tick-borne encephalitis. Climate change may also be partl...

In Connecticut and the northeastern United States, the blacklegged tick, Ixodes scapularis (commonly known as the deer tick) is the vector for four disease agents; Borrelia burgdorferi, Anaplasma phagocytophilum, Babesia microti, and the deer tick virus (DTV) that cause Lyme disease, human granulocytic anaplasmosis, human babesiosis, and Powassan encephalitis, respectively. There are around 3,0...

It is already known that the beagle breed of domestic dogs produces semiochemicals capable repelling brown dog tick, Rhipicephalus sanguineus sensu lato (s.l.). With a view to discovering new non-host as tick repellents, we compared produced by putative tick-resistant dog, miniature pinscher, with (beagle) and tick-susceptible (English cocker spaniel) breeds. Two compounds beagles, i.e. 2-hexan...

background : ticks are important vectors and reservoirs of crimean congo hemorrhagic fever (cchf) virus. human beings may be infected whenever the normal life cycle of the infected ticks on non- human vertebrate hosts is interrupted by the undesirable presence of humans in the cycle. a total of 26 species of argasid and ixodid ticks have been recorded in iran; including nine hyalomma, two rhipi...

A 24year old man presented to the emergency department with complain acute onset pain abdomen for 3days. The pain started in the umbilical region, later became diffuse. There was no history of fever, vomiting or irregular bladder and bowel habits. He consulted twice in the nearby hospital for pain abdomen. Routine blood investigation, including ultrasonography of the abdomen and pelvis was also...

Ticks are distributed worldwide and significantly impact human and animal health. Due to severe problems associated with the continuous use of acaricides on animals, integrated tick management is recommended. Increasing public health concern over the tick-borne diseases demands the strategic control of ticks on animals that transmit diseases to human beings. Immunological control of tick vector...

To understand the epidemiology of tick infestation and tick-borne diseases in pet dogs in south-eastern China and to develop a reference for their prevention and treatment, we collected 1550 ticks parasitizing 562 dogs in 122 veterinary clinics from 20 cities of south-eastern China. Dogs were tested for common tick-borne pathogens; collected ticks were identified and processed for the detection...

Borrelia burgdorferi synthesizes a variety of differentially regulated outer surface lipoproteins in the tick vector and in vertebrate hosts. Among these is OspD, a protein that is highly induced in vitro by conditions that mimic the tick environment. Using genetically engineered strains in which ospD is deleted, we demonstrate that this protein is not required for B. burgdorferi survival and i...

Anaplasma phagocytophilum are transmitted by Ixodes spp. ticks and have become one of the most common and relevant tick-borne pathogens due to their impact on human and animal health. Recent results have increased our understanding of the molecular interactions between Ixodes scapularis and A. phagocytophilum through the demonstration of tissue-specific molecular pathways that ensure pathogen i...

Interest in microbial communities, or microbiota, of blood-feeding arthropods such as ticks (order Parasitiformes, suborder Ixodida) is increasing. Studies on tick microorganisms historically emphasized pathogens of high medical or veterinary importance. Current techniques allow for simultaneous detection of pathogens of interest, non-pathogenic symbionts, like Coxiella-LE and Francisella-LE, a...
