A range of analytical methods (GC-MS, LC-MS, voltammetry, microbiological and microscopic techniques, PCR) was used to assay a range of potential chemical and biological contaminants in soil and dandelion samples. The results provide the first comprehensive safety analysis of dandelion as a herbal product. Samples were collected from three differen...

Infection with Thelazia nematodes results in eye disease in wild and domestic animals. The aim of the present study was to describe the occurrence of Thelazia nematodes in European bison, and to subject the isolated parasites to molecular identification and phylogenetical analysis. The eyeballs of 18 European bison from the Bieszczady Mountains, cu...

Although the significance of red deer (Cervus elaphus) and roe deer (Capreolus capreolus) as hosts and their role in the circulation of vector-borne pathogens in Europe is well described, the trypanosomes of moose (Alces alces) are poorly known. As heat sensitive ungulates, moose might be especially vulnerable to the effects of climate change and t...

Wild large ungulates, like European bison (Bison bonasus) and Eurasian moose (Alces alces), form an important part of the circulation of Anaplasma phagocytophilum, a Gram-negative, intracellular, tick-transmitted bacterium, in the natural environment. Bison and moose tissue samples were subjected to 16S rDNA, groEL and ankA partial gene marker ampl...

Background: The role of cervids in the circulation of A. phagocytophilum has not yet been clearly determined; however, several species of wild and farm cervids may be a natural reservoir of this bacteria. Methods: Spleen and liver tissue samples were taken from 207 wild (red deer, roe deer, fallow deer and moose) and farmed cervids (red deer and...

Purpose The Anaplasma genus includes a Gram-negative bacterium infecting the blood cells of wild and domestic mammals, causing tick-borne fever. Infection with pathogenic Anaplasma phagocytophilum strains may cause Human Granulocytic Anaplasmosis. Wild boars ( Sus scrofa ) may act as natural wild reservoir hosts for potentially zoonotic A. phagocyt...

Introduction. Echinococcus multilocularis has been endemic in red foxes in eastern and central parts of Europe, and E. granulosus s. l. identified in wolves in some countries. In recent years, wolves hale emerged as potentially important definitive hosts of E. multilocularis. Objective. This aim of the survey was to record indirectly using nested-P...

Purpose. The nematodes of the genus Thelazia are the cause of eye diseases of wild and domestic ruminants throughout the world. The aim of the study was to describe clinical cases of thelasiosis in European bison (Bison bonasus) in Poland, and provide morphometrical features of Thelazia gulosa Railiet and Henry, 1910 and Thelazia skrjabini Erschov,...

The tapeworm Taenia lynciscapreoli is a new species of the genus Taenia described in 2016, and which remains poorly understood. The aim of the present study is to extend current knowledge regarding its, morphology and genome. Biological material was analysed from three species of wild animals: Eurasian lynx (Lynx lynx), roe deer (Capreolus capreolu...

Background: Anaplasma phagocytophilum is an obligate parasitic intracellular bacterium. It is the causative agent of granulocytic anaplasmosis, with effects on human and animal health. In Europe, the pathogen is mainly transmitted among a wide range of vertebrate hosts by blood-sucking arthropods. The aim of this study was to determine the presenc...

Anaplasma sp. is Gramm – negative bacteria, which is an obligatory intracellular parasite of animals and humans. The largest reservoir is made up by small rodents and wild animals e.g.: wild boar (Sus scrofa), roe deer (Capreolus capreolus), and red deer (Cervus elaphus). The widespread occurrence of this potentially pathogenic bacteria in the envi...

The article examines the presence of metacestodes on the liver capsule in two wild boars and on the liver capsule and mediastinum in moose. Cysticerci were identified as Taenia hydatigena metacestodes by morphological features—size and shape of rostellar hooks and molecular analysis of the partial sequences of cytochrome c oxidase subunit 1 gene. M...

This study presents the results of analysis spleen and liver from randomly selected wild boars. Molecular analysis was based on the variations of polymerase chain reaction (PCR). In this study were examined 20 wilds boars (20 livers, 20 spleens; n = 40). Six positive samples were detected using the PCR method (5 from livers; 1 from spleen). DNA seq...

This work has led to the identification and characterization a tapeworm of the Taenia sp. described for the first time in the world (Finland) in 2016. The experiments was based on classical microscopic analysis and the use of various polymerase chain reaction (PCR) of the parasite, which hosts is the Eurasian Lynx - Lynx lynx. In our knowledge this...
