Adiaspiromycosis is a rare fungal infection caused by saprophytic fungi Emmonsia spp. (type Ascomycota) occurring especially in small free-living mammals. The aim of this study was to evaluate the occurrence of histopathological lesions asscociated with adiaspiromycosis in the Eurasian beaver inhabiting Poland. In order to evaluate the presence of natural adiaspiromycosis we systematically investigated...
The purpose of this study was to assess the possible influence of beavers on the contamination of lake water with zoonotic parasites Giardia duodenalis and Cryptosporidium spp., with respect to the risk to human health. A total of 79 water samples were taken around the habitats of beavers from 14 localities situated in the recreational Masurian Lake District (north-eastern Poland). Water was sampled...
Parasitological examination after necropsies of 48 European beavers from Podlaskie and Warmisko-Mazurskie provinces were performed between April 2011 and November 2012. All helminthes were isolated from the contents of the gastro-intestinal tract and their species were determined. In addition, blood samples and faeces were examined. All beavers were infected with six species of parasites. Stichorchis...
This study describes the expression of DßH as a marker of sympathetic (catecholaminergic) innervation in the vestigial uterus of adult European bison (Eb) bulls. Cryo-sectioned uteri were examined by fluorescent immunohistochemistry with the use of primary rabbit DßH polyclonal antibodies. The DßH-immunocomplexes (antigens/polyclonals) were visualised by secondary donkey antirabbit biotinylated IγG,...
This study was performed on the European bison and aimed at determining the existence of a placental dopamine ß-hydroxylase (DßH; EC 1.14.17.1) protein expression localised by fluorescent immunohistochemistry (F-IHC); and at identifying a profile of the DßH expression throughout the placenta development. Placentomal sections were prepared from the placentas collected from females during two pregnancy...
The respective investigations were carried out at the Experiment Station Popielno, Polish Academy of Sciences on crosses heifer-calves and bull-callves of the genotypes of 50% Hereford, 25% black-and-white, 25% bison (16 heads) as well as 50% Charolais, 25% black-and-white and 25% bison (13 heads). The bull-calves were subjected to the control fattening from the 13th week of life to reaching the weight...
