To explore the competence of American robins as a reservoir for Lyme disease spirochetes, we determined the susceptibility of these birds to tickborne spirochetes and their subsequent infectivity for larval vector ticks. Robins acquired infection and became infectious to almost all xenodiagnostic ticks soon after exposure to infected nymphal ticks. Although infectivity waned after 2 months, the...

The purpose of this study was to specify the occurrence and prevalence of Babesia microti in hard ticks removed from dogs in Warsaw (central Poland). Among 590 collected ticks, 209 were identified as Ixodes ricinus, and 381 as Dermacentor reticulatus. B. microti DNA was detected in 11 out of 590 (1.86%) samples of ticks. The DNA of the parasite was detected only in lysates from female I. ricinu...

BACKGROUND Rickettsia conorii conorii is the etiological agent of Mediterranean spotted fever, which is transmitted by the brown dog tick, Rhipicephalus sanguineus. The relationship between the Rickettsia and its tick vector are still poorly understood one century after the first description of this disease. METHODOLOGY/PRINCIPAL FINDINGS An entomological survey was organized in Algeria to co...

Ticks are responsible for transmitting viral, bacterial, and protozoal diseases to humans animals also cause significant economic damage the livestock industry. The owner of farmhouse prefers use acaricides, a key component tick control strategies. However, indiscriminate irresponsible acaricides has detrimental effect on increase in contamination environment, acaricide resistance ticks, its re...

The concentration-time profile, therapeutic, and persistent efficacy of a single subcutaneous injection of cattle with a long-acting (LA) formulation of ivermectin at a concentration of 630microg/kg of body weight were determined against Rhipicephalus (Boophilus) microplus. Ivermectin sera concentration in treated cattle increased to 13.0ppb within 1d after treatment, and peaked at 26.2ppb at 1...

Ixodes scapularis ticks are clinically important hematophagous vectors. A single tick bite can lead to a polymicrobial infection. We determined the prevalence of polymicrobial infection with Borrelia burgdorferi, Anaplasma phagocytophilum, Babesia microti, Borrelia miyamotoi, and Powassan virus in 286 adult ticks from the two counties in New York State where Lyme disease is endemic, utilizing a...

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...

The present study aimed to determine the phenology and predilection sites of ticks infesting cattle in western region Djurdjura (North Algeria) from November 2018 October 2020. Nineteen farms located thirteen localities within four provinces were visited monthly for two years. Among 289 examined cattle, 64.36 ± 2.81% (n=189) infested by ticks. Of 10,243 collected ticks, most abundant tick speci...

  Proteases play a key role in protein digestion in ticks and other haematophagous insects. Our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. Cells of the midgut endocytose blood components. Blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. In this...
