Ascarididae nematodes of genera Toxocara and Toxascaris are of significant epizootic relevance among predatory mammals from families Canidae and Felidae. Localization of these nematodes in the definitive hosts, their morphology, as well as the measurements of eggs and adult worms are similar. Recently, molecular techniques have provided alternative(More)
Genus Mesocestoides is a representative of the small cyclophyllidean family Mesocestoididae that is found parasitizing the small intestine of carnivores. The life cycle of cestodes from this genus is complex and requires two intermediate hosts. Cysticercoids are produced in the first intermediate host (oribatid mites), which when eaten by the second(More)
Heligmosomoides polygyrus is a widespread gastro-intestinal nematode infecting wild Apodemus (wood mice) throughout Europe. Using molecular and morphological evidence, we review the status of Heligmosomoides from Apodemus agrarius in Poland previously considered to be an outlying clade of H. polygyrus, to further resolve the status of the laboratory model(More)
Blood samples from Apodemus agrarius from Poland yielded PCR amplicons of Bartonella species. These included B. grahamii, B. taylorii, and B. birtlesii, as is typical of European Apodemus, as well as B. elizabethae-like forms and a recombinant strain of B. taylorii, most closely related to an American isolate from Tamiasciurus hudsonicus.
The genus Brachylecithum was for the first time subject to molecular taxonomic phylogenetic analysis in order to ascertain relationships among its component taxa. We used two markers—the nuclear ribosomal 28S ribosomal DNA (rDNA) gene and the mitochondrial cox1 gene, for six species of the genus; 11 sequences of partial 28S rDNA and partial cox1 were(More)
This study aims to establish the relative contribution of rodent populations from diverse habitats to the occurrence of rodent-borne pathogens of public health significance. Rodents (n = 492) represented by Apodemus agrarius, A. flavicollis and Myodes glareolus, were captured in live traps in four localities of southwestern Poland (2009-2012). For the(More)
Echinostomes are cosmopolitan digenean parasites which infect many different warm-blooded hosts. Their classification is extremely confused; the host spectrum is wide, and morphological similarities often result in misidentification. During our long-term studies on the helminth fauna of rodents and carnivores we have collected 27 collar-spined echinostomes(More)
The raccoon (Procyon lotor) carnivore native to North America is a fast spreading, invasive species in the Europe now. At the moment, the highest population occupies areas near the German-Polish border. The data on the occurrence of Cryptosporidium spp. and microsporidia in raccoons is limited to North America’s territory and is totally lacking in the case(More)
The paper presents a survey of nematodes found in 49 rodents of 4 species from 17 localities of the Jelenia Góra district (SW Poland). The following parasites were found: Heligmosomoides polygyrus (Dujardin, 1845) Boulanger, 1922; Heligmosomoides glareoli Baylis, 1928; Heligmosomum mixtum Schulz, 1929; Heligmosomoides sp.; Heligmosomidae gen. sp.;(More)
