Stimulated by demands of the natural environment conservation, the need for thorough structural and functional identification of microorganisms colonizing different ecosystems has contributed to an intensive advance in research techniques. The article shows that some of these techniques are also a convenient tool for determination of the physiological state(More)
UNLABELLED BACKGROUND AIM AND SCOPE: The objective of the study was to determine the effects of ca. 35 years of pesticide contamination (pesticide dump-PD) of Lake Szeląg Wielki (located in the north-eastern Poland) on changes in the microbial communities of aquatic ecosystems. In the years 2008-2009, analyses were carried out for seasonal changes in the(More)
The effect of pesticide contamination of the littoral zone on the population of bacteria and fungi was analyzed using the example of a eutrophic water reservoir exposed for >30 years to the influence of expired crop-protection chemicals, mainly DDT. For three consecutive years, quantity analyses of bacteria and fungi were conducted and the composition of(More)
Ehrlichiosis is the multiorgan infectious disease caused by small, intracellular rickettsias from the genus Ehrlichia. These microorganisms are known as an etiologic factor of infections world wide in humans and in different species of animals. Dog ehrlichiosis can be caused by several species of Ehrlichia attacking different groups of blood cells, but most(More)
An eight-year-old gelding, Wielkopolski Horse was presented with a pink tumour, which filled the entire palpebral fissure of the left eye. Ultrasonography revealed it to be well-demarcated from the cornea mass, which covered its entire surface. Due to the extensive size of the lesion and the lack of owner’s consent to postoperative treatment, it was decided(More)
Peat bog lakes represent important ecosystems in temperate and boreal zones. We investigated the seasonal dynamics of the microbial community in two small peat bog lakes, Kuźnik Olsowy and Kuźnik Bagienny, located in western Poland. Fluorescence in situ hybridization analyses revealed that the bacterial community was dominated by Proteobacteria and(More)
Hydrological conditions are responsible for the changes in lateral connectivity between the main river channel and the floodplain lakes, a factor controlling zooplankton abundance and diversity. We tested the hypothesis that the degree of connectivity between the aquatic habitats and the river channel governs the zooplankton densities and community(More)
A six year old crossbred male dog presented with non-pigmented, pale pink, unhaired, ulcerative tumor of the medial canthus and upper eyelid region. As treatment, surgery was proposed. During the surgery complete excision of the tumor was performed. The extent of skin loss, especially in the upper eyelid required plastic reconstruction by pedicle flap(More)
Urinary incontinence in animals poses a growing therapeutic problem. Satisfactory results in the treatment of incontinence are not reported despite the wide availability of pharmaceuticals addressing the problem. The growing number of side effects and the need for sustained pharmacotherapy have prompted a search for new treatment methods. The experiment(More)
The peritoneal dialysis was carried out in dogs for the fist time in 1946. Since then, this method of therapy has been applied more and more frequently in veterinary medicine. The dialysis therapy is mainly recommended in the acute renal failure. Accordingly to the time period over which dialysis is performed and the flow pattern of the dialysate, different(More)
