The effect of isotonic multiple electrolyte infusions during anesthesia on blood gas and enzymatic values in horses. General equine anesthesia is accompanied by the risk of complications and even death. The majority of general anesthetics used in veterinary practice lead to arterial hypotension, decreased capillary perfusion and ventilatory depression leading to pathological changes referred to as postanesthetic myopathy. In this study an attempt was made to analyze changes in the perioperative and postoperative acid-base equilibrium and blood enzymatic activity in horses, subject to the intensity of the applied fluid therapy. The horses were divided into two groups: I--administered Ringer's solution during ...
Partial sequence analysis of the L1 gene of bovine papillomavirus type 1 detected by PCR with MY09/MY11 primers in equine sarcoids in Poland. BPV-1 is now recognized as a main etiological agent of equine sarcoids. The etiopathogenesis of the equine sarcoids is equivocal and is not yet fully understood. The aim of the present study was to analyse a partial sequence of the L1 gene of BPV associated with equine sarcoids in Polish horses. After clinical diagnosis, 40 skin lesions obtained from 29 horses were collected. The amplicons of a fragment of BPV L1 DNA were detected using PCR with MY09/MY11 primers in 31 specimens. All of them were recognized as BPV-1. Phylogenetic analysis has allowed the amplicons of partial L1 gene to be divi...
Prevalence of gastrointestinal parasites in working horses. Fecal samples for detection of gastrointestinal parasites were collected from 221 working horses from September 2002 to May 2003 from 14 villages in Urmia, North West of Iran. Fecal samples of 46 horses (20.8%) were negative for parasite eggs or oocysts. One hundred and seventy five positive horses (48.9%) were infected with a single parasite type and 49 (22.2%) and 18 (8.1%) of horses had multiple infections with two and three parasites, respectively. The highest prevalence and intensity rate belonged to small strongyles. The overall prevalence of intestinal parasites eggs and oocyst in the p...
Muscle damage, hydration, electrolyte balance and vasopressin concentrations in successful and exhausted endurance horses. Arginine vasopressin (AVP) is released in response to depletion of the effective circulating blood volume. Endurance horses might develop exhaustion because loss of water and electrolytes in sweat with hypovolaemia and electrolytes abnormalities. Therefore, AVP should act in the control of volemia in these animals. This research evaluates the differences in AVP, hydration, electrolyte status and serum muscle enzymes in successful endurance horses in comparison with those eliminated from the competition because of exhaustion. Eighteen endurance horses, divided into two groups, successful (n = 1...
Morphological and biochemical changes in the blood of horses naturally infected with Gasterophilus sp. larvae. Gasterophilus sp. constitute a group of specific parasites, which larval forms are found in horses and other phylogenetically related species--donkeys, mules and zebras. Their invasion is associated with marked fluctuations of hematological and biochemical blood parameters, including the activity of many enzymes and the electrolyte concentration. The purpose of the study was to analyze changes in selected biochemical and morphological blood parameters of horses infected with botfly larvae. The experimental group was formed of horses infested by Gasterophilus sp. larvae whereas the control grou...
The effect of the 162 km endurance ride on equine peripheral blood neutrophil and lymphocyte functions. Strenuous exercise is recognized as a stress, which may induce functional immunodeficiency and increase individual susceptibility to infection. It has been shown in equine athletes, that alterations in leukocyte functions occur after moderate and submaximal exertion, however, no data deal with the effect of extreme physical exertion. In this study, we evaluated leukocyte functions (neutrophil oxidative burst and lymphocyte proliferation activity in response to mitogens) in horses following the CEI 3* 162 km endurance ride. Exercise-induced stress was manifested as neutrophilic leukocytosis and...
Pregnancy influences the hematological profile of Carthusian broodmares. In order to investigate the effect of pregnancy on equine hematological profile, venous blood samples were taken from 44 Carthusian broodmares every two weeks during pregnancy, divided into three periods: I (conception to 110 days), II (111-220 days) and III (222 days to delivery). Routine hematological analysis was performed. Packed cell volume (PCV) increased in period II probably as a consequence of the climatic conditions or as a result of physical stress of lactation during period I. After that, a reduction in PCV was found but this was not matched with a similar decrease in total serum p...
The relationship between concentrations of vitamin D-binding protein (DBP) in serum and colostrum of mares and in serum of their foals in the neonatal period. Vitamin D-binding protein (DBP) participates in the actin scavenger system, it is a carrier of vitamin D and its derivatives, it manifests the capacity to bind mainly monounsaturated and saturated fatty acids, it binds to the surface of several cells and enhances chemotactic activity of C5a of the complement. The present study was aimed at answering the question whether serum DBP level in mares is related to levels of this protein in colostrum and in serum of its progeny. For this purpose, sera from 77 mares, colostra from 72 mares and sera from 69 Thoroughbred foals were collected. Mother's a...
Parascaris and cyathostome nematodes in foals: parasite in transit or real infection? Faecal egg counts were performed in 187 foals of a large Polish stud farm between February and September 2007. Eggs of Parascaris equorum were present in faeces of 7% and those of cyathostomins in 13% of the foals aged less than 194 days. Information dealing with age of foals and/or efficiency of ivermectin treatment as well as the nematode parasite prepatent periods, it can be conducted that most of the infections recorded on the basis of faecal egg counts were false-infections in animals up to the age of six months, probably due to the ingestion of infected faeces of their dam or some other ...
The presence of anti-Yersinia pseudotuberculosis immunoglobulins in equine serum. The research was conducted on clinically healthy mares (n = 40) and foals (n = 78) during Y. pseudotuberculosis associated enzootics. The animals were divided into groups: I to IV--mares, IA to IVA--their offsprings, IB to IVB--foals which mothers were not treated with any medicaments. The animals in group I, IA and IB were injected with PBS; in group II, IIA and IIB--with Y. pseudotuberculosis strain-based vaccine, in group III, IIIA and IIIB--with P. acnes strain-based immunostimulator; in group IV, IVA and IVB--with P. acnes strain-based immunostimulator and (5 days after the immunostimulat...
Equine herpesvirus type 1 (EHV-1) replication in primary murine neurons culture. Equine herpesvirus-1 (EHV-1) infections cause significant economic losses for equine industries worldwide as a result of abortion, respiratory illness, and neurologic disease in all breeds of horses. The occurrence of abortions caused by EHV-1 has repeatedly been confirmed in Poland, but neurological manifestations of the infection have not been described yet. Also it is unknown how the infection of neurons with non-neuropathogenic strains is regulated. To further understand the virus-neuron interaction we studied two strains of EHV-1 in murine primary neuron cell cultures. Both strains were i...
Acid-base balance parameters and a value of anion gap of arterial and venous blood in Małopolski horses. The comparative study of the acid-base balance (ABB) parameters has been performed on 20 clinically healthy mature Małopolski horses. An arterial blood sample from the facial artery and a sample of venous blood from the external cervical vein were colected from each animal. In the samples tested, the blood pH, pCO2, tCO2, HCO3-, concentration of Na+, K+, Cl-, and a value of the anion gap were determined. The difference among pCO2, tCO2, and HCO3- in both samples tested was statistically significant, whereas the pH of the arterial blood and the pH of the venous blood did not differ significant...

The objective of the study was to determine if there were differences in Cr, Mn, Cu, Cd, Pb and Ni levels in coat hair and hoof horn between Polish Konik horses maintained in stabled and reserve systems in Roztocze National Park in Poland. Summer and winter feeding seasons (seasons of the year in case of hooves) and age of horses were taken into account. 107 samples of hair and hooves, as well as all kinds of feed and sources of water available for the horses were examined. The results of the study indicate that the concentration of the elements in the coat hair, hoof horn, feeds and water is ...
Equine herpesvirus type 1 quantification in different types of samples by a real-time PCR. Equine herpesvirus type 1 (EHV-1) is one of the major viral agents causing diseases in horses common worldwide. A variety of techniques, including PCR, have been used to diagnose EHV-1 infections. In this paper, an attempt of real-time PCR has been described, which uses specific fluorochrome-labeled TaqMan probes for detection of viral DNA. This method does not require post-amplification manipulations, thereby reducing the risk of cross-contamination. The assay was sensitive enough to detect EHV-1 sequences in different clinical samples, as well in mice neuronal cell cultures. The technique wa...
Occurrence of strongyles (Strongylidae) in horses from small farms on the basis of necropsy. Three parts of the large intestine, i.e. the dorsal and ventral colon, and caecum in 41 working horses from small farms in southern Poland were examined. Five species of large strongyles (3 migratory species from genus Strongylus and 2 non-migratory from genus Triodontophorus) and as well as 17 species of cyathostomes were revealed. The prevalence of large strongyles was observed, accordingly: Strongylus vulgaris--80.5%, S. equinus--9.8%, S. edentatus--4.9%, Triodontophorus serratus--19.5% and T. brevicauda--7.3%. Among cyathostomes, 5 most prevalent species were Cyathostomum catinatum--31.7%,...
Serum homocysteine and oxidative stress evaluation during exercise in horse. The aim of the present work was to evaluate the influence of exercise on serum homocysteine and oxidative stress in Thoroughbreds during official races. For our study, ten Thoroughbred mares, 5 years old and clinically healthy, were used. The horses were trained to take part in an official 2100 meter race. Reactive oxygen species (dROMs), antioxidant barrier (Oxy-adsorbent), thiol antioxidant barrier (SHp) and homocysteine (sHcy) were investigated. Blood samples, collected from each horse at rest, immediately after the race, and 30 and 180 min after the end of the race, were collected by jugul...
Replication of equine herpesvirus type 1 in equine dermal cells transfected with Bam HI[G] restriction fragment of EHV-2 genome. In previous experiments, we have demonstrated that the presence of equine herpesvirus 2 (EHV-2) enhanced plaque formation in cell cultures infected with equine herpesvirus type 1. To determine whether a specific region of the EHV-2 genome is responsible for this effect, we have constructed a library of Bam HI fragments of the EHV-2 genome ligated into pcDNA plasmid. Equine dermal (ED) cell cultures were subsequently transfected with the constructs, passaged 5 times, tested for the presence of the plasmids and infected with EHV-1 at MOI = 0.01. Only in cultures transfected with the pcDNA/Bam HI...

Comparative activities of semicarbazide-sensitive amine oxidase (SSAO) in five domestic species. Semicarbazide-sensitive amine oxidase (SSAO) activity was measured spectrophotometrically using benzylamine as a substrate, in the serum of healthy males and females of horses, camels, cattle, sheep and goats. The animals were born and raised in the same area, and the blood collection was made on the same day to avoid variations. Also the concentrations of protein and copper were measured in the same samples. There were no significant gender-related differences in SSAO activity between the tested animals regardless of species. Activities of SSAO in either male or female of horse were significa...
Hypothermic storage of equine isolated hepatocytes. The aim of the study was to establish the optimal methods for hypothermic storage of equine isolated hepatocytes. Viability of equine isolated hepatocytes after hypothermic storage was dependent on the type of storage medium as well as on the cell density in the storage suspension and the preservation period. Hepatocytes stored at 4 degrees C in Hanks' Balanced Salt Solution (HBSS) and Williams' Medium E (WE) for 24 h showed very low viability, numerous cell membrane blebs, very low attachment rate (11.9 +/- 6.5% and 34.8 +/- 19.1%, respectively) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenylte...

Pathomorphological and immunohistochemical study of selected markers of tumour cell proliferation in equine sarcoids. The purpose of the study was a pathomorphological and immunohistochemical analysis of tumour cells and connective tissue in equine sarcoids. Investigations were performed using histopathological, ultrastructural, immunohistochemical (PCNA, p53, cytokeratin, vimentin) and histochemical (Ag-NORs) methods. The study was conducted on 50 sarcoids originating from 36 horses and classified as occult, verrucous, fibroblastic and a mixed type of sarcoid based on their clinical appearance. Most of the tumours were located on the girth (30%), neck (24%), head (12%), and legs (12%). The average age of the...
Comparison of the blood plasma catecholamines level in thoroughbred and Arabian horses during the same-intensity exercise. The aim of this study was to compare changes in epinephrine (E), norepinephrine (NE) and dopamine (DA) levels in blood plasma of two racehorses breeds: Arabian and Thoroughbred during moderate intensity exercise performed in the same conditions. The increase in plasma E level just after exercise was higher in Thoroughbreds than in Arabians. During the whole test, the Arabians showed the higher levels of NE and DA as compared to those found in Thoroughbreds.
Changes in structure of lymphatic organs in foals died due to Rhodococcus equi infection. The aim of this study was to investigate the structure of lymphatic organs in foals which died due to Rhodococcus equi infection. The material for this study consisted of 9 foals, of both genders, various breeds, 6-14 weeks old. The routine histopathological examination and immunocytochemical reaction for cytokeratine-3 receptors revealed the disturbances in the thymus epithelial cells development. This was manifested by a complete lack of cells expressing cytokeratine-3 receptors, as well as absence of normal thymocytes differentiation. The supposed thymus epithelial cells were very few, expr...
The coagulation system in horses with colic. Colic in horses very often induces changes in the coagulation system causing the development of disseminated intravascular clotting. It is promoted by blood concentration and an increase in exposition of coagulation activators with a simultaneous decrease in coagulation inhibitors activity, mainly antithrombin III. Progressing blood platelets aggregation supports production of microthromboses and plugging capillary vessels. The progression of this processes causes complications in basic disease and becomes the reason for therapeutic failure. Determination of coagulation system indexes such as ...
Antioxidant parameters of horses according to age, sex, breed and environment. Antioxidant defences interact to form an integrated system. There is no comprehensive and uniform view on issues concerning the antioxidant status in horses. Therefore, the aim of the present study was to estimate antioxidant parameters in horses of different age, sex and breed as well as environment and relationship between different antioxidants. Parameters of selected antioxidants including superoxide dismutase (SOD), glutathione peroxidase (GSH-px), total antioxidant status (TAS), ceruloplasmin (CP), bilirubin, uric acid, zinc, copper and selenium were determined in blood of 80 clinically ...
Ascarid nematodes in domestic and wild terrestrial mammals. The biology of the ascarid nematodes has been discussed in the context of their important economic role in farm animals, pet animals and zoo animals with special attention to carnivores and primates. In farm animals, infection with the most common roundworm of horses (Parascaris equorum) and swine (Ascaris suum) depend on many factors such as environmental conditions (larval development in the egg and egg survival), age of the host, breed, husbandry system, hygiene and treatment schedule. The monoxenic ascarids Toxocara canis and T. cati are the most important nematodes in carnivorous animals ...
The use of chosen serological diagnostic methods in Lyme disease in horses. Part II. Western blot.
