Preliminary Results on the Helminthofauna of the Eurasian Lynx (Lynx Lynx) in Latvia
2003
In the article, preliminary data on the helminthofauna of the Eurasian lynx (Lynx lynx) in Latvia are presented. Material for the research on the helminthofauna was collected and investigated from 1999 to 2002. A total of 42 individuals was examined for helminths. Helminth species occurring most frequently in the Eurasian lynx and helminths dangerous to people were established. Six helminth species belonging to the following taxonomic groups were found: one species (Taenia pisiformis) of Cestoda and five species (Toxocara mystax, Thominx aerophilus, Trichinella sp., Capillaria felis-cati, and Nematoda sp.) of Nematoda.
Development of a Novel Method for Identification of Alaria alata Mesocercariae by Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spe…

Alaria (A.) alata mesocercariae (AM) have increasingly appeared as incidental findings during the mandatory inspection of wild boars for Trichinella in many European countries. An Alaria spp.-specific PCR is available for the identification of AM
Trichinella spiralisThymidylate Synthase: Developmental Pattern, Isolation, Molecular Properties, and Inhibition by Substrate and Cofactor Analogues
1996
Abstract Thymidylate synthase specific activity was found to remain at a constant level in crude extracts from muscle larvae, isolated (1-15 months after infection) by pepsin-HCl digestion, as well as from adult worms ofTrichinella spiralis.The enzyme was purified and its molecular (monomer mol. wt 35 kD) and kinetic (sequential mechanism with the Kmvalues 3.1 and 19 μM for dUMP and N5,10-methylenetetrahydrofolate, respectively) properties determined. 5-Fluoro-dUMP was a competitive, slow-binding inhibitor of the parasite enzyme. N5,10-methylenetetrahydrofolate analogues 10-propargyl-5,8-dideazafolate (CB3717), ZD1694, BW1843U89, and AG337 were weaker inhibitors of the parasite than regener…
The subnivium, a haven for
2019
Parasite nematodes of the genus Trichinella are transmitted from one host to another through the ingestion of larvae present in striated muscles. The longer the survival of muscle larvae in host carcasses, the higher the probability of being ingested by a scavenging host. Thereby, these nematodes developed an anaerobic metabolism favouring their survival in decaying tissues. In addition, muscle larvae of three taxa, namely Trichinella nativa, Trichinella britovi and Trichinella T6, can survive freezing for several months to several years depending on the taxon. The aim of the present work was to investigate the survival time of T. britovi larvae in naturally infected host carcasses preserve…
The wild boar (Sus scrofa, Linnaeus, 1758) as an important reservoir host for Alaria alata in the Baltic region and potential risk of infection in hu…
2020
Abstract Alaria alata trematode is widely distributed throughout Europe and has a complex life cycle in which wild boar serve as a reservoir host. The primary aims of the present study are to establish the occurrence of A. alata mesocercariae in naturally infected wild boar in Latvia and to assess the risk for humans to acquire A. alata infection via consumption of wild boar meat. By summarizing long-term data using the Trichinella inspection method from 2014 to 2019, the overall A. alata prevalence was 8.3%, of which significantly higher A. alata prevalence was observed during the summer seasons. Additionally, 43.9% (n = 485) of wild boar were found to be infected with A. alata using Alari…
