Objective. An important role in the prevention of diseases, the causative agents of which are transmitted by ixodic ticks (tick-borne encephalitis, ixodic tick-borne borreliosis, human granulocytic anaplasmosis, human monocytic erlichiosis) is assigned to non-specific measures. To prevent infection by all pathogens of these infections at the same time, nonspecific preventive measures are of paramount importance. They include the extermination of hungry ticks on the vegetation of relatively small areas of natural biotopes, forest parks, health institutions, recreational areas, summer cottages or gardens; individual protection of the population from ticks and awareness-raising work. Materials and methods. The data of official statistics and materials of long-term observation of epidemic process were analyzed. Results. Despite the fact that since 2016 according to official data, there is observed a phase of decreased activity of the epidemic process of tick-borne infections, statistical analysis shows that in the forthcoming years an activation of epidemic situation is expected. Conclusions. In order to prevent tick attacks, specialists of medical organizations, departments of Rospotrebnadzor of the Russian Federation should intensify sanitary and educational work on non-specific protection of the population. In addition to standard activities, it is important to organize schools, courses for the public, schoolchildren, tourists and other population groups for the prevention of tick-borne infections, including the development of skills for correct tick removal using the Tick Removal Trainer and an algorithm for emergency measures in specific situation.

In the territory of the Primorsky region, the nosoareas of causative agents of tick-borne infections often coincide and lead to mixed infection of ticks, which causes the mixed pathology in humans . We investigated ixodid ticks taken from people during the epidemic season of 2019 for the spectrum of pathogens of transmissible infections to determine the degree of their mono- and mixed infection. 651 specimens of ixodid ticks investigated. RNA/DNA pathogens was determined by the method of polymerase chain reaction (PCR), TBEV antigen by ELISA. The presence in ticks of pathogens of the following diseases was detected: Lyme borreliosis (35.3%), tick-borne replasing fever (11.3%), human granulocytic anaplasmosis (2.6%), human monocytic ehrlichiosis (2.4%), tick-borne encephalitis (1.8%), tick-borne ricketsiosis (1.0%). As agents of mono-infections, the virus of TBE, ehrlichia, anaplasma and rickettsia in ticks occurred less frequently than in combination with other pathogens. A high frequency of occurrence B. burgdorferi s.l. in mono-infection detected (58.7%). B. miyamotoi has met evenly at ticks with mono- and mixed infections. Total mixed infection of ticks was 23.1%. Borrelia have been identified in all mixed cases. Variants of double combinations (95.5 % of cases from all mixed infections) were as follows: B. burgdorferi s. l. + A. phagocytophilum, B. burgdorferi s.l. + E. chaffeensis / E. muris, B. burgdorferi s.l. + TBEV, B. burgdorferi s.l. + R. heilongjiangensis, B. burgdorferi s.l. + B. miyamotoi. The most frequent combination was B. burgdorferi s.l. + B. miyamotoi (37.8% of all mixed infections). In triple infection of B. burgdorferi s.l. + A. phagocytophilum + TBEV and B. burgdorferi s.l. + A. phagocytophilum + B. miyamotoi, the frequency of occurrence for each combination was 2.2%. Given the above, a complex laboratory diagnosis of tick-borne infections in individuals who have been bitten by a tick is necessary, including the detection of all pathogens common in focal areas.

Molecular genetic monitoring of natural focal of tick-borne infections in the epidemic season of 2018 revealed infectiousness of ixodid ticks causative agents of tick-borne encephalitis (0.58% of cases), Lyme disease (31% of cases), human monocytic ehrlichiosis (1.6% of cases) and granulocytic anaplasmosis (3.9% of cases) is registered and also co-infections of ticks by these infections (2.9% of cases) is revealed in natural and anthropourgic foci (B. burgdorferi s.l.+A. phagocytophilum, B. burgdorferi s.l.+E. chaffeensis/E. muris and B. burgdorferi s.l.+tick-borne encephalitis virus). The major epidemiological importance of ticks of the species I. persulcatus is found, their share being 87,6%. The majority of patients being bitten by a tick were from the southern and southeast areas of Primorye. Contamination of ticks with Borrelia was revealed not only in I. persulcatus, but also in ticks of the Haemaphysalis and Dermacentor. The infectiousness of ticks of B. burgdorferi s.l. (42,3%), tick-borne encephalitis virus (7,7%) and A. phagocytophilum (15,4%) was highest on Russky Island.

We present an infant with acute fever, thrombocytopenia, and leukopenia, coming from an endemic region for tick-borne encephalitis, human granulocytic anaplasmosis, and hantavirus infection. The primary human herpesvirus 6 infection was diagnosed by seroconversion of specific IgM and IgG and by identification of viral DNA in the acute patient’s serum. The patient did not show skin rash suggestive of exanthema subitum during the course of illness.

In Poland, out of the 21 species of ticks described, two species have the greatest epidemiological significance: Ixodes ricinus and Dermacentor reticulatus. Their participation in the transmission of etiologic agents of vector diseases such as Lyme disease, tick-borne encephalitis, human granulocytic anaplasmosis, babesiosis, rickettsiosis and many others is widely known. Due to the often severe and sometimes fatal course of diseases transmitted by ticks, a great deal of emphasis is placed on prophylactic activities, minimizing the possibility of biting and transfering pathogens along with the arachnid saliva. In addition to means of personal protection, including appropriate clothing, protective vaccinations, avoiding tick habitats or body checking after returning from this type of places, one of the most important elements of anti-tick prevention is the use of effective repellents. The key role of using the repellent is to discourage the arthropod from attacking and to prevent it from taking food, as a result of which there is no phenomenon of transmission of pathogens from the hematophage to the host organism. The most commonly used substances with arthropod repellent properties are: N-N-diethylm-toluamide (DEET), 3-(N-acetyl-N-butyl) aminopropionic acid ethyl ester (IR3535), icaridine, permethrin and essential oils. However, it should be remembered that no repellent ever protects 100% all the time after application - its use should be considered as one of many elements of personal protection in the prevention of tick bites.

It may seem perplexing that there is any uncertainty in Australia about the existence of zoonotic tick-associated infections1–3. Outside this country, particularly in the northern hemisphere, tick-borne diseases such as human granulocytic anaplasmosis, babesiosis, Boutonneuse fever, ehrlichiosis, Lyme borreliosis, and tick-borne encephalitis, have well documented aetiologies, epidemiology, diagnostic methods, and treatments. Why is Australia different and what research is being conducted to address this issue? This article briefly addresses these questions and explains how high-throughput metagenomic analysis has started to shed light on bacterial microbiomes in Australian ticks, providing new data on the presence and distribution of potentially zoonotic microbial taxa.

Objective of the work was to carry out complex assessment of the current state of epizootic activity and epidemiological significance of the infectious disease natural foci in the Aleksandrovsk-Sakhalin territory of the Sakhalin Region. Trapped were 56 samples of small mammals in July, 2010; collected were 180 specimens of taiga tick imago, caught were 1000 specimens of mosquitoes. 223 samples of blood sera were taken from residents of the region. All the field data were tested to detect specific antibodies, antigens and genetic material of agents. Based on the results of epizootiological investigations, serological and molecular-genetic assays, demonstrated was the occurence of natural foci of leptospirosis, tularemia, tick-borne encephalitis, borreliosis, rickettsiosis, human granulocytic anaplasmosis, human monocytic ehrlichiosis, West Nile fever, Inco fever, Batai and Geto fevers, as well as HFRS with varying degree of activity manifestation in the territory of the region. Isolated was tick-borne encephalitis virus from mosquitoes.
