Numerous studies have provided evidence that Echinococcus granulosus exists as a complex of different strains, that differ in a wide variety of criteria that have an impact on the epidemiology, pathology and control of cystic hydatid disease (CHD) and, to date, 10 distinct genotypes (G1-G10) have been identified. In Italy, sequence analysis of the(More)
The present study was undertaken to characterize more thoroughly aetiological agent of cystic echinococcosis that still represents a health problem in the Slovak Republic. Sequencing of the mitochondrial ND1 gene, Random Amplified Polymorphic DNA (RAPD) analysis and isoenzyme analyses were used to characterize genetically protoscolices of 37 isolates from(More)
Infection of Trichinella spp. is widespread among wildlife in Slovakia and the red fox (Vulpes vulpes) is the main reservoir of Trichinella britovi. Trichinella spiralis has been rarely documented in sylvatic and domestic animals of this country. During routine examination of domestic pigs at the slaughter, Trichinella larvae were detected by artificial(More)
A sample of 22 Echinococcus granulosus isolates collected from 12 sheep and ten humans from a focus of cystic echinococcosis in western Turkey was examined by DNA sequencing of four mitochondrial genes (cox1, atp6, nad1, rrnS). Results demonstrated the presence of two species of E. granulosus complex, E. granulosus sensu stricto and E. canadensis. Of E.(More)
TwoProteocephalus species,P. neglectus La Rue, 1911 andP. exiguus La Rue, 1911, parasites of salmonid and coregonid fishes, were compared morphologically, biometrically, and electrophoretically. The study revealed that the two taxa cannot be differentiated by the morphological criteria used. No fixed allelic difference was found. In all, 12 of 13 enzymes(More)
Variability in Echinococcus granulosus is very important epidemiologically since strain characteristics may influence local patterns of transmission of hydatid disease. To classify the genotype presented in pig protoscoleces of the Slovak territory, a DNA-based approach has been used. Nucleotide sequences for a 471 bp region of the mitochondrial NADH(More)
45 red foxes (Vulpes vulpes) from various regions of Latvia were examined by necropsy between 2003 and 2008 for the presence and infection intensity of Echinococcus multilocularis. The overall prevalence was 35.6 %, with the intensity of infection ranging from 1 to 1438. Although a limited number of foxes were examined, the prevalence was high and infected(More)
The host specificity and distribution of Eubothrium crassum (Bloch, 1779) and Eubothrium salvelini (Schrank, 1790), morphologically fairly similar pseudophyllidean tapeworms parasitizing salmonid fish, were critically assessed on the basis of morphological and genetic evaluation of extensive material collected from different definitive hosts and(More)
BACKGROUND The taxonomic distinctiveness of Ascaris lumbricoides and A. suum, two of the world's most significant nematodes, still represents a much-debated scientific issue. Previous studies have described two different scenarios in transmission patterns, explained by two hypotheses: (1) separated host-specific transmission cycles in highly endemic(More)
Here we examine 3157 foxes from 6 districts of the Slovak Republic in order to determine for the first time the distribution, prevalence and identity of Mesocestodes spp. endemic to this part of central Europe. During the period 2001-2006, an average of 41.9% of foxes were found to harbour Mesocestoides infections. Among the samples we confirmed the(More)
