Article Synopsis
  • Ticks are ectoparasites that can transmit harmful pathogens to humans and animals, and this study focused on how altitude and soil pH affect the presence of these pathogens in tick populations in Slovakia.* -
  • The research found that higher altitudes generally increased the likelihood of certain pathogens in ticks, while soil pH also played a role in pathogen occurrence for specific microorganisms, but various factors influence this relationship beyond just altitude and soil pH.* -
  • Although the study's regression models provided insights into factors affecting pathogen presence in ticks, they explained only a small amount of the variability, suggesting that other unknown influences are at play.*

  • A parasitic protozoan, transmitted through tick bites and other means, poses a severe risk to dogs, particularly affecting pregnant mothers and their puppies.* -
  • A study found that 75% of a litter born to an infected American Pit Bull Terrier were infected, with one puppy dying shortly after birth.* -

Article Synopsis
  • - Ticks transmit various pathogens, increasing the need for effective control measures like acaricides and environmentally friendly practices, such as habitat modification and biological control.
  • - Researchers detected tick-specific parasitoid wasps in several tick species using genetic methods in the Slovak Karst National Park, marking the first molecular identification of these wasps in specific tick species in that region.
  • - The study found that certain tick species not only hosted wasps but also highlighted that these wasps can target multiple tick species, including those less harmful to human and animal health.

Birds and mammals share various ectoparasites, which are responsible for the transmission of a wide range of pathogens. The louse flies (family Hippoboscidae) are ectoparasitic dipterans feeding strictly on the blood of mammals and birds. Both sexes of the louse flies are obligatory hematophagous and are known to act as the vectors of infectious agents.

Background: Bronchial hyperresponsiveness (BHR) is a key feature of asthma, but it may also appear in allergic rhinitis. The type of allergen, as well as regional characteristics, play an important role in the development of BHR. The aim of our study was to analyze allergen sensitization patterns and the factors that affect BHR in allergic rhinitis patients living in temperate continental climate zone.

is a tick-borne protozoal blood parasite that may cause hemolytic anemia, thrombocytopenia, lethargy, and/or splenomegaly in dogs. Many drugs have been used in management of canine babesiosis such as monotherapy or combined treatment, including diminazene aceturate, imidocarb dipropionate, atovaquone, and antibiotics. This report examines the effectiveness and safety of Malarone, azithromycin (AZM) and artesunate (ART) combination for the treatment of babesiosis in dogs naturally infected with .

Taenia hydatigena is a cosmopolitan tapeworm that uses canids or felines as definitive hosts, while the larval stage (metacestode), formerly referred to as cysticercus tenuicollis, infects a wide variety of intermediate hosts, in particular ruminants. In the present study, we used partial nucleotide sequences of the cox1 and nad1 genes of T. hydatigena from different animal species to analyse the intraspecies genetic diversity of this economically important parasite.

  • Dirofilaria immitis is a parasitic worm that can cause pulmonary dirofilariasis in humans, who are not its primary hosts.
  • A case of D. immitis infection was identified in a woman from Slovakia, marking a local occurrence of this parasite.
  • The increasing presence of this parasite in Europe highlights the urgent need for accurate diagnostic methods to detect infections.

In HIV (human immunodeficiency virus) infected people, the immunodeficiency caused by a reduced level of CD4 (cluster of differentiation 4) T-lymphocytes increases the risk of infectious diseases. Additionally, in individuals with immunologically compromising conditions, tick-borne or some parasitic pathogens may cause chronic, debilitating opportunistic infections and even death. The study aimed at determining the IgG seropositivity of HIV-infected patients to , spp.

Article Synopsis
  • A study conducted in Slovakia aimed to monitor the presence and spread of West Nile virus (WNV) and Usutu virus (USUV) through mosquito populations, addressing the lack of formal surveillance in the region.
  • Over two years, researchers trapped and analyzed 4,508 mosquitoes, finding WNV in 3 pools and USUV in 16 pools; USUV was more widespread and lasted longer in seasonal detection.
  • The study highlighted a significant finding of WNV in urban Bratislava, alongside a confirmed human infection, emphasizing the need for better surveillance to mitigate public health risks from these viruses.

Ticks will diminish productivity among farm animals and transmit zoonotic diseases. We conducted a study to identify tick species infesting slaughter bulls from Adama City and to screen them for tick-borne pathogens. In 2016, 291 ticks were collected from 37 bulls in Adama, which were ready for slaughter.

Article Synopsis
  • The study aimed to investigate the prevalence of various tick-borne pathogens in ixodid ticks collected from five regions in Ukraine, addressing the data gap on this issue compared to Western Europe.
  • A total of 524 ticks were collected, identified as three species, and analyzed for pathogens using PCR, revealing varying prevalence rates of different pathogens among ticks.
  • This research is significant as it provides the first prevalence data for certain pathogens in three Ukrainian regions and the first detection of Neoehrlichia mikurensis in ixodid ticks there.

This survey is aimed at investigation of species composition of fleas removed from small terrestrial mammals captured in rural, suburban, and urban types of habitat and molecular screening of the presence and diversity of species in collected ectoparasites. In total, 279 fleas (Siphonaptera) belonging to 9 species of 2 families, Ceratophyllidae and Hystrichopsyllidae, were collected from 115 (46%) out of 250 trapped small mammals of eight species (, , , , , , , and ). spp.

Article Synopsis
  • The study focuses on the ornate sheep tick, Dermacentor marginatus, which is common in Europe and studies its role in spreading diseases, but notes a lack of genomic information about these ticks.
  • Researchers sequenced the complete mitochondrial genome of a female tick from Slovakia, finding it to be 15,067 base pairs long with 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes, sharing gene order and codon usage patterns with other Metastriata ticks.
  • The findings include insights into the tick's noncoding regions and phylogenetic relationships, suggesting D. marginatus is closely related to other Dermacentor species, contributing to future research on tick evolution and taxonomy.
