The generalist tick Ixodes ricinus is the most important vector for tick-borne pathogens (TBP), including Borrelia burgdorferi sensu lato, in Europe. However, the involvement of other sympatric Ixodes ticks, such as the specialist vole tick I. trianguliceps, in the enzootic circulations of TBP remains unclear. We studied the distribution of I. ricinus and I. trianguliceps in Central Finland and estimated the TBP infection likelihood in the most common rodent host in relation with the abundance of the two tick species. Ixodes trianguliceps was encountered in all 16 study sites whereas I. ricinus was frequently observed only at a quarter of the study sites. The abundance of I. ricinus was positively associated with open water coverage and human population density around the study sites. Borrelia burgdorferi s. l.-infected rodents were found only in sites where I. ricinus was abundant, whereas the occurrence of other TBP was independent of I. ricinus presence. These results suggest that I. trianguliceps is not sufficient, at least alone, in maintaining the circulation of B. burgdorferi s. l. in wild hosts. In addition, anthropogenic factors might affect the distribution of I. ricinus ticks and, hence, their pathogens, thus shaping the landscape of tick-borne disease risk for humans.

“…This review focuses on pathogens transmitted by I. ricinus, the vector of numerous human pathogens, most notably TBE virus and certain species of the Borrelia burgdorferi sensu lato (s. l.) complex that cause Lyme borreliosis [31,32]. Evidence of SAT is also considered involving the sympatric and parapatric species, I. persulcatus (found in parts of northern Europe and northern to north-eastern Asia), and the allopatric species of North America, I. scapularis [33][34][35][36][37].…”

Tick saliva is a complex mixture of peptidic and non-peptidic molecules that aid engorgement. The composition of tick saliva changes as feeding progresses and the tick counters the dynamic host response. Ixodid ticks such as Ixodes ricinus, the most important tick species in Europe, transmit numerous pathogens that cause debilitating diseases, e.g. Lyme borreliosis and tick-borne encephalitis. Tick-borne pathogens are transmitted in tick saliva during blood feeding; however, saliva is not simply a medium enabling pathogen transfer. Instead, tickborne pathogens exploit saliva-induced modulation of host responses to promote their transmission and infection, so-called saliva-assisted transmission (SAT). Characterization of the saliva factors that facilitate SAT is an active area of current research. Besides providing new insights into how tick-borne pathogens survive in nature, the research is opening new avenues for vaccine development.

В связи с повсеместным увеличением численности и активности клещей, связанным с изменением климата, ландшафта, миграцией животных и птиц, а также активным отдыхом людей, наблюдается расширение ареала возбудителей ИКБ в РФ, происходит появление новых очагов и расширение границ старых, распространение ИКБ в южные регионы [6,7].…”

Background. Ixodes tick-borne borreliosis (TBB) is a clinically multifaceted disease posing a serious threat in most territories of the Russian Federation. New TBB outbreaks emerge and spread to the country’s south.Objectives. The review highlights the TBB clinical diversity to physicians in order to improve the diagnosis quality and opportune aid. It focuses on the early and late clinical presentation of localised and disseminated polysystemic TBB.Methods. Sources were mined in the MEDLINE, PubMed and national electronic databases (Сyberleninka, eLibrary, etc.) with keywords “tick-borne borreliosis” [клещевой боррелиоз], “Lyme disease” [болезнь Лайма], “Lyme arthritis” [Лайм-артриты], neuroborreliosis [нейроборрелиоз] for the period of 2014–2020. Selected impactive publications within 2007–2013 were also included. Research was considered eligible if borreliosis was diagnosed using specific techniques like immune-enzyme assays, immunoblotting or PCR.Results. TBB is a common and cross-disciplinary situation. The disease may progress occult or manifest in a variety of forms, from annular erythema to cardiac, peripheral and central nervous system involvement or arthritis. The polysystemic nature of lesions, often long-term of the tick bite, forces multiple specialist visits ending with misdiagnoses, late aetiotropic therapy and transition into a chronic phase through ignorance of the patient’s epidemiological record. Some patients may have the acute phase followed by irreversible neurological damage associated with memory loss, cognitive decline, arthrosis and sclerotic skin change reducing the quality of life.Conclusion. TBB can be mimicked by therapeutic, neurological, skin and ophthalmic illnesses, which warrants the physician’s attention to the epidemiological record and knowledge of specific diagnostic techniques. Further research is necessary into the pathogenesis and clinical presentation of chronic TBB and its residual manifestations.
