This study investigates the prevalence of spp. in tick populations in different forest habitat types (broadleaf forest, mixed broadleaf and coniferous forest, and coniferous forest) in south-western Poland. During the survey periods from April to June 2018 and 2019 a total of 494 ticks, including 374 nymphs, 60 females and 60 males, were tested for infections by nested PCR targeting the A gene.

Article Synopsis
  • * A total of 445 ticks were collected from 28 lizards, with higher tick counts found on Lacerta agilis compared to Zootoca vivipara, and the presence of Borrelia spp. was notably higher in ticks from L. agilis.
  • * The findings highlighted the significance of lizards as tick hosts and their role in the persistence of pathogens in urban areas, marking the first detection of certain pathogens in these ticks.

This article presents the current state of knowledge of mosquito species (Diptera: Culicidae) occurring in Poland. In comparison to the most recently published checklists (1999 and 2007), which listed 47 mosquito species, four species (, , , and ) are added to the Polish fauna. Our new checklist of Polish mosquito fauna includes 51 species of mosquitoes from five genera: (30), (8), (1), (7), and (5).

(1) Background: In addition to the microclimate, host availability, and tick microbiota, soil environmental microorganisms can affect tick populations. This study aimed to (1) determine the presence and diversity of entomopathogenic fungi (EF) in forests, where ticks are abundant, and (2) estimate the effectiveness of the isolated EF strains against . (2) Methods: EF were isolated using the trap insect method from soil collected from tick sites.

In Europe, ticks are particularly important vectors of pathogens known as tick-borne pathogens (TBP). TBP can influence hosts, including domestic animals and humans as well as ticks. This review focuses on interactions between hard ticks and medically and veterinary significant bacterial pathogens i.

The ornate dog tick (Dermacentor reticulatus) shows a recently expanding geographic distribution. Knowledge on its intraspecific variability, population structure, rate of genetic diversity and divergence, including its evolution and geographic distribution, is crucial to understand its dispersal capacity. All such information would help to evaluate the potential risk of future spread of associated pathogens of medical and veterinary concern.

Ornate dog tick, Dermacentor reticulatus is an important vector of Babesia canis, and Rickettsia spp. and other pathogens of veterinary and public health interest. The current study is the first to investigate the long-term changes in prevalence of these pathogens in expanding tick populations in Central Europe.

Ticks are important ectoparasites and vectors of pathogens that cause disease in humans and animals. The natural habitat of Ixodes ricinus ticks is forests, which are convenient habitats to search for hosts, including reservoir hosts, and therefore can be an important habitat source of tick-borne pathogens. The aim of the study was to assess the usefulness of detailed forest habitat-type maps to estimate the tick-borne risk at a local scale (Lower Silesia, SW Poland).

Article Synopsis
  • Tick-borne diseases, particularly canine babesiosis, are becoming more significant in Poland due to an expanding population of the tick species Dermacentor reticulatus, which is split into Eastern and Western groups by a non-endemic area.
  • A three-year study (2016-2018) monitored these tick populations, revealing an average range expansion of 2.5-10 km per year along river basins and a decrease in distance between the two groups.
  • The incidence of canine babesiosis was low in Western Poland and the gap area, but significantly higher in Central and Eastern Poland, highlighting a strong geographical and temporal link between tick populations and disease outbreaks.

The range of D. reticulatus is discontinuous in Europe, with a gap between the Western and Eastern European populations. Recent studies have shown, however, a decrease in the gap as a consequence of D.

Entomopathogenic fungi of the genus Beauveria and Metarhizium play an important role in controlling the population of arthropods. However, the data on their effectiveness against ticks focus mainly on species that do not occur in Europe. The aim of the study was to assess the effectiveness of entomopathogenic fungi against two of the most important tick species in Europe: Ixodes ricinus and Dermacentor reticulatus.

Article Synopsis
  • Bacillus thuringiensis (Bt) is a microorganism known for its effectiveness against insects, though its impact on tick populations is not fully understood.
  • In experiments with four environmental strains and a commercial product (Vectobac), Vectobac was found ineffective, while two environmental strains showed an 80% tick mortality rate against Ixodes ricinus and Dermacentor reticulatus.
  • The study also suggested that the similarity in enzymatic profiles between effective and less effective strains indicates that the enzymes tested may not play a significant role in how these strains affect ticks.

This paper presents the distribution of questing Ixodes ricinus ticks in suburban forest intensively visited by people. The local-scale observations conducted during a 4-year study at 99 plots (of 100m each) located throughout the entire area of a riparian urban forest, showed a high variation in the density of ticks from year to year. Although I.

Unlabelled: Tests performed in 2013 and 2014 revealed the occurrence of three tick species parasitizing pet cats and dogs in the Wrocław Agglomeration. In total, 1,455 tick specimens were removed from 931 hosts (760 dogs and 171 cats) in 18 veterinary clinics. The dominant tick species was Ixodes ricinus (n=1272; 87.

This paper presents the unexpected winter activity of Dermacentor reticulatus (Fabricius, 1794) ticks in a newly emerging population in south-west Poland. Host-seeking ticks were collected from vegetation in January 2016 in a meadow ecosystem in six sites located in the Wroclaw Agglomeration, as well as from ten companion animals. A total of 238 questing D.

Background: Tick-borne infections are no longer confined to rural areas, they are documented with increasing frequency in urban settlements across the world. They are known to cause diseases in humans as well as in their companion animals.

Methods: During a period of 2 years, from January 2013 until December 2014, ticks were collected from dogs and cats in 18 veterinary clinics in the Wrocław Agglomeration, Poland.
