Expression of CD4, CD8, and CD25 surface markers on T lymphocytes and levels of IFNγ, IL-10, and TNF-α in colostrum and milk were determined in sows vaccinated against Trueperella pyogenes in the final stage of pregnancy. The autovaccine, prepared from Trueperella pyogenes, administered twice to pregnant sows six and three weeks before the anticipated delivery significantly increased the percentages...
The aim of this study was to investigate pathomorphological changes in the duodenum, jejunum, ileum, and caecum of Japanese quails naturally infected with Eimeria tsunodai. Samples of the intestines were collected from 6-week-old cockerels and hens before laying and from laying quails aged 12, 24, and 48 weeks. The tissue sections were stained with haematoxylin and eosin, PAS method according to McManus,...
The aim of the study was to assess the distribution of Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, and Babesia canis in adult females and males of Ixodes ricinus and Dermacentor reticulatus ticks, inhabiting meadows near large forest complexes throughout the Lubelskie Voivodship (eastern region of Poland). Ticks were collected using the flagging method. Among 720 ticks collected, 506...
The study aimed at evaluation of pathological lesions on flexor surface of navicular bone and deep digital flexor tendon in horses graded in standard X-ray examination as 2 (fair). The evaluation was performed on fifteen horses (6-9 years of age). Analysis procedure involved examining navicular bones on X-ray pictures, post-slaughter preparation of navicular bones from the hoof capsule, macroscopic...
The aim of the study was to provide a detailed phenotypic and genotypie charaeterisation of Staphylococcus aureus strains and the group of microorganisms with unusual biochemical patterns (called Staphylococcus aureus-Mke) isolated from table chicken eggs. All of the strains tested exhibited resistance to at least one of the 17 antibiotics tested, and 55.55% of isolates were found to be resistant...
The experiment was conducted on 30 Holstein-Friesian cows: 10 cows in the follicular phase of the cycle and in the luteal phase 10 d later, 10 cows with follicular cysts, and 10 with luteal cysts. The presence of the ovarian structures was confirmed by ultrasonography. Serum levels of progesterone and 17ß-oestradiol were tested with ELISA. Samples for cytological examination were collected from the...
The aim of the study was to determine a growth rate of Salmonella Enteritidis in cooked ham stored under different temperatures and to compare usefulness of the mathematical models for describing the microbiological data. The samples of cooked pork ham were inoculated with the mixture of three Salmonella Enteritidis strains and stored at 5°C, 10°C, 15°C for 21 d, and at 20°C and 25°C for 5 d. The...
The aim of the study was to investigate the presence of a (Erα) and ß (Erß) oestrogen receptors in rabbit male's claustrum, and thus to examine whether oestrogens may influence nerve cells' functions of this structure, llie material for the study was obtained from the brains of seven rabbits. To detect the presence of Erα and Erß, specific monoclonal antibodies were used. T"he expression of Erα...
The aim of the study was to determine the prevalence of canine dirofilariosis in four provinces of central-eastern Poland and to describe pathological changes occurring during the course of this parasitosis. A total of 188 dogs aged from one and a half up to 16 years were examined for dirofilariosis. Blood samples were analysed for the presence of microfilariae using Knott method, as well as the method...
The undertaken study aimed at analysing the effect of linseed oil used in diets for turkey hens on contents of pro- and antioxidants in their tissues. Additionally, correlations were analysed between the contents of these compounds in blood, liver, and muscles of the birds. The experiment was conducted on 240 one-week-old turkey hens reared until 16 weeks of age, randomly allocated into two feeding...
The aim of the study was to determine and compare the concentrations of chlorinated hydrocarbons residues (DDT, DDE, DDD, γ-HCH) in the milk fat of selected species of farm animals. The experiment was carried out on cow's, sheep's, goat's, and mare's milk samples originating from different parts of north-eastern Poland. The samples were prepared using Röse-Gottlieb's and Ludwicki's methods. The determination...
The aim of the study was to determine the concentrations of lead (Pb), cadmium (Cd), and mercury (Hg) in the liver, kidneys, and muscles of European heavers (Castor fiber) and thus to evaluate the degree of heavy metals contamination in Wannia and Mazury region in Poland. The study was conducted on free-living beavers captured in region of Warmia and Mazury during autumn 2011. Concentrations of the...
A chromatographic procedure for determination of oxytetracycline (OXT), tetracycline (TC), chlortetracycline (CTC), and doxycycline (DC) in water samples was developed and was applied for the analysis of water samples collected from poultry and pig farms and environmental water samples. Samples were acidified with trifluoroacetetic acid to pH 3 and further purified by solid phase extraction using...
The expression of galanin (GAL) and its three receptors (GalR1, GalR2, and GalR3) were studied with real-time PCR in the colonic wall of pigs suffering from experimental colitis caused by the infection with Brachyspira hyodysenteriae. The expression was studied in the muscular membrane, mucosa/submucosa layer, and in lymphocytes isolated from mucosa/submucosa. The expression levels were normalized...
The aim of this study was to investigate the causes of chronic respiratory disorders in Polish Konik horses maintained in a stable and pasture, under condition typical for pleasure horses in Poland. The study was conducted on 14 adult horses, consistent with regard to environment and living conditions. The horses were divided into two groups: seven horses not affected by any respiratory problem (control...
Immune and oxidative parameters were evaluated as indicators of the influence of stress on the occurrence of respiratory syndrome in feedlot calves. The study was carried out on 60 2 and a half-month-old Simmentaler calves transported at feedlot. Mean daily feed consumption, daily weight gain, and behavioural activity were evaluated. Blood was collected on days 1, 3, 7, 14, 21, and 28 of feedlot....
The study aimed to demonstrate the expression of hypoxia-inducible factor (HIF-1α) in soft tissue mesenchymal tumours (fibroma and fibrosarcoma) in dogs. An attempt was made to correlate the obtained results with density of blood vessels (expression of von Willebrand Factor, vWF), expression of Ki-67 proliferation antigen, and with intensity of apoptosis in studied tumours. The study was performed...
The aim of the study was to demonstrate differences in the gene expression of signalling pathways between healthy dogs and dogs with chronic mitral valve disease in different heart failure groups. Blood samples were collected from 49 dogs of various breeds between 1.4 and 15.2 years of age. Isolated RNA samples were analysed for quality and integrity and the gene expression profile was determined...
