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...

the concept of soft sets, introduced by molodtsov [20] is a mathematicaltool for dealing with uncertainties, that is free from the difficultiesthat have troubled the traditional theoretical approaches. in this paper, weapply the notion of the soft sets of molodtsov to the theory of hilbert algebras.the notion of soft hilbert (abysmal and deductive) algebras, soft subalgebras,soft abysms and sof...

Ticks were collected from ruminants in various areas of Sudan in 1998 and 2000. Primer pairs of rickettsial citrate synthase gene (gltA) and a spotted fever group (SFG) rickettsial 190-kDa surface antigen gene (rompA), respectively, were used for identification. Polymerase chain reaction (PCR)-positive products were used for DNA sequencing. The gltA gene was detected in 55% of the ticks examine...

Because of differences among hosts in reservoir competence for tick-borne diseases, the distribution of larval blacklegged ticks on hosts might determine tick infection prevalence and disease risk to humans. We conducted a three-part study to determine the factors responsible for greater burdens of larval blacklegged ticks on white-footed mice than on eastern chipmunks. A microhabitat study ind...
