The aim of the study was to investigate the effect of LPS injections on non-specific mechanisms of immunity in pigeons. On the first day of observation the experimental birds (n=18) were intravenously injected with Escherichia coli LPS (10 μg/kg b.w.), while the control animals (n=6) received in the same way apyrogenic physiological saline. On the second and the third day of the experiment LPS in...
The effect of Enterococcus faecium CCM7420 (EF) – enterocin-producing and probiotic strain of rabbit origin, Eleutherococcus senticosus extract (ES) and their combination (ES+EF) was determined on selected bacteria in faeces and caecum content, leukocytes phagocytosis, blood biochemistry and growth performance. Ninety-six weaned rabbits were divided into 3 experimental (ES, EF, ES+EF) and control...
A total of 42 Brucella strains were isolated from animals in Poland in years 2003-2012. Most of them (N=37) originated from wild animals, 3 from cattle, 1 from pig and 1 from sheep. The strains were characterised using both bacteriological and molecular (Bruce-ladder and MLVA) methods. The examinations revealed that all strains from wild boars, hares, cattle and pigs (N=41) had the same phenotypic...
Biomaterials originate from natural substances and are widely used in medicine. Although they have to satisfy many conditions to be useful for treatment, more and more research is carried out with new types of biomaterials that can help replace various tissues such as tendons and bones. Chitosan is a very promising material, revealing unique features, which makes it useful for veterinary medicine...
The major duodenal papilla (papilla of Vater) is an important structure associated with the biliary tract and, in some species, the pancreas. It usually represents a slight elevation on the intestinal mucosa where the dilated junction (ampulla of Vater) of the commmon bile duct and pancreatic duct enters the duodenum. The ampulla is surrounded by a specifically arranged muscle structure called the...
Alkylphenols and their precursors, alkylphenol etoxylates, are a group of manmade chemicals used mainly as surfactants in domestic and industrial applications worldwide. It has been well established that they have endocrine disruption activity, hepatotoxic, genotoxic and other negative effects on animal and human health. In spite of the effort to reduce their use, they persist in the environment not...
The aim of the presented study was the estimation of optimal Ca and P levels applied before calving together with anionic salt addition, as an element of hypocalcaemia and hypophosphataemia prevention. The experiment was carried out during the dry period on 48 cows with similar milk yield in the previous lactation. Cows were divided into four groups. In group I (control) the amount of minerals was...
This paper describes research on the levels of endogenous melatonin (MLT) in the blood serum in dogs in different seasons (March, June, September, December) and at different times of day (11:00, 12:00, 23:00, 24:00 and 1:00), using immunoassay method. Blood samples were collected in the diurnal cycle, in consecutive seasons. The conducted studies show that MLT levels undergo clear changes in both...
The aim of the study was to investigate the effect of different energy concentrations in the isonitrogenous diet fed during the dry period on postpartum health, fertility and blood variables. Forty Holstein multiparous cows were dried 56 days before the expected day of calving and assigned to group (M) with moderate energy concentrations of 0.69 UFL/kg DM or to the low-energy group (L) with energy...
Semen quality assessment methods are very important in predicting the fertilizing ability of persevered spermatozoa and to improve animal reproductive technology. This review discusses some of the current laboratory methods used for semen quality assessments, with references to their relevance in the evaluation of male fertility and semen preservation technologies. Semen quality assessment methods...
The aim of this field study was to assess the impact of a single i.m. injection of lysozyme dimer and flunixin meglumine in combination with intramammary and systemic antibiotic on chemiluminescence of PMN (polymorphonuclear leucocytes) and subpopulations of lymphocyte T in blood of cows with E. coli mastitis. Examinations were performed on 30 dairy cows affected with naturally occurring acute form...
The aim of the present study was to assess metabolic changes occurring in Holstein cows with left or right abomasal displacement. Total sialic acid (TSA) values of the left abomasal displacement (LDA) group were elevated significantly (p<0.0001) as compared to the controls. In the LDA group, serum ceruloplasmin (CPN) and aspartate transaminase (AST) levels were increased significantly (p<0.0001)...
Wind farms produce electricity without causing air pollution and environmental degradation. Unfortunately, wind turbines are a source of infrasound, which may cause a number of physiological effects, such as an increase in cortisol and catecholamine secretion. The impact of infrasound noise, emitted by wind turbines, on the health of geese and other farm animals has not previously been evaluated....
The rabbit is a good experimental model for brachial plexus surgery. The risks of death during anesthesia were significantly greater in rabbits than cats or dogs. This article presents the protocol of injectable anesthesia for a short surgical procedure, safe for the rabbit patient and convenient for the surgeon.
Recent years have seen in both human and veterinary medicine the development of numerous techniques allowing for evaluation and classification of changes in individual organs and tissues. Despite introduction of such techniques into diagnostics as among others, CT, MRI, CEUS or elastography, biopsy is still considered a “golden standard” and it is a procedure performed in order to obtain a final diagnosis...
Magnetic resonance is a great diagnostic tool in equine lameness examination. Its value is most significantly visible in evaluating distal extremities. Problems with podotrochlear apparatus, laminitis or distal interphalangeal joint osteoarthritis are the most common disorders diagnosed in equine patients. Without using magnetic resonance it was impossible to clearly assess which structures are involved...
This study investigated the distribution and chemical coding of neurons in intramural ganglia of the urinary bladder trigone (UBT-IG) and cervix (UBC-IG) in the male pig using combined retrograde tracing and double-labelling immunohistochemistry. Additionally, immunoblotting was used to confirm the presence of marker enzymes for main populations of autonomic neurons. Retrograde fluorescent tracer...
Viruses replicating in the nucleus need to cross the nuclear membrane barrier during infection, therefore disruption of specific nuclear transport pathways is crucial for their replication cycle. In the present study we have investigated the influence of nucleo-cytoplasmic transport inhibitors – ivermectin and leptomycin B, on EHV-1 replication in primary murine neurons. Obtained results suggest that...
The aim of the present study was to examine the correlation between the results of lymphocyte proliferative test (LPT) specific to food allergens and allergic skin diseases in dogs. Investigations were performed in 138 dogs with allergic skin diseases diagnosed in a private animal hospital. Of the 138 animals, 97 cases had positive reactions in LPT specific to food allergens. Of these 97 dogs, 67...
