Description:

Wild birds across the globe can carry the causative agent of avian borreliosis, Borrelia anserina, and that of human Lyme borreliosis, Borrelia burgdorferi sensu lato in the ticks attached to them. Currently, only limited proof exists for the presence of these pathogens in samples taken from living wild birds, carried by the birds as a reservoir, without symptoms. We investigated blood samples of large-bodied wild birds admitted to a bird hospital, where basic clinical symptoms were recorded. Thirty-six blood samples were collected from them, according to the DualDur kit methodology, and investigated using dark-field microscopy to search for spirochetes. Five of the samples were also investigated by immunofluorescence microscopy to identify Borrelia burgdorferi. Since the main reason for admittance to the hospital was a physical injury, no significant symptoms were observed regarding a current Borrelia infection. Out of the sixteen birds of prey, eleven (68%) were infected with spirochetes, and fifteen out of twenty storks (75%) were also infected with spirochetes, without major symptoms. All five samples investigated using immunofluorescence were confirmed to contain the human pathogenic Borrelia burgdorferi sensu lato. Thus, direct investigations of the blood of wild birds may show the asymptomatic prevalence of Borrelia in the wild bird population.

Description:

From 2015 to 2023, we conducted a comprehensive study in the 11,893-hectare hunting area managed by the Marcal-Bitvaközi Hunting Company, characterised by its substantial wild boar population. The research was carried out across various settings, including a free-range wild boar garden during large-scale hunts and free-living areas during individual hunts. We examined 216 wild boars in total, with 173 individuals from free-living areas and 43 from free-range areas. Throughout the sample collection process, we encountered numerous technical challenges that are infrequently detailed in the professional literature, often mentioned only tangentially. This oversight in existing publications neglects the significance of addressing field sampling difficulties, which are crucial for ensuring the precision and accuracy of research. This paper details the equipment requirements, sampling methodologies, and practical solutions to streamline fieldwork. While our primary focus was on endoparasitic infections of the stomach and small intestine, the described methodologies and findings are broadly applicable to research involving all internal organs.

Description:

SERTÉS Background: Coronary artery disease is the leading cause of death in the developed countries and myocardial infarction is the most serious manifestation of the disease. Swine are being chosen with increasing frequency as subject for interventional cardiology research. Their similarities to humans in their cardiovascular physiology, size and coronary anatomy make them better experimental subjects than most species. Moreover, regular human coronary catheter systems and techniques can be readily used to access their coronary vasculature. Objectives: In this paper, a simple swine model of human myocardial infarction is studied in detail using a percutaneously inserted balloon catheter. The main role of the present paper is to introduce and troubleshoot the technique and its potential pitfalls. Materials and Methods: Myocardial infarction was confirmed by the detection of ST segment elevation on the surface ECG, total creatine kinase release, gadolinium enhanced contrast MRI scan and by histology. Results and Discussion: We conclude that if investigators are familiar with both human and animal research, this model is practical, inexpensive and can provide reproducible and consistent infarct sizes that closely mimic the human myocardial infarction. With very careful technique inducing LAD infarction distal to the second diagonal branch and done by trained team, our mortality was lower than in the literature, only 12.5%. It was also proven that the size of myocardial infarction induced by this technique was big enough to be used for different interventional cardiology research. From our study, it is clearly visible, that only a close collaboration between veterinary medicine and human cardiology can avoid the difficulties of complex swine coronary experiments and leads to success.

Page Range: Unknown

Description:

Ascaris suum and Macracanthorhynchus hirudinaceus cause a large loss of yield in farm animals as well as in free-living and captive wild boar herds, thereby causing economic damage. This study compared A. suum and M. hirudinaceus infections in free-ranging and captive wild boars (Sus scrofa) in Hungary. The authors measured the A. suum and M. hirudinaceus infections of a 248-hectare wild boar garden and an 11,893-hectare free-living wild boar herd in the sample area. In all cases, samples were collected from shot wild boars. In total, 216 wild boars were examined from June 2015 to June 2023 in Hungary. Of the 173 dissected wild boars from the wild, 57 (32.9%) were infected with A. suum, while 30 (69.8%) of the 43 individuals from the captive area were infected. The prevalence of M. hirudinaceus in the free-living area population was 9.25% (16 wild boars), while that of the captive population was 34.89% (15 wild boars). In the case of the examined helminths, the captive herd was 36.9% more infected than the herd living in the open area.

Description:

The main objectives of this survey were to identify correlations between housing arrangements and prevalence of abnormal repetitive behaviors (ARBs) in equine society. Data were collected by an email questionnaire from 60 participants (stables, owners, equine experts) between 2018 and 2020 in Hungary to determine the prevalence of ARBs associated with housing conditions in the equine population. The questionnaire documented information about location, number of horses present, type of horse, and management systems (pasture, corral, stable). The resultant inventory of compulsive behaviors covered 486 Thoroughbreds managed by 20 gallop trainers, 265 Trotting horses managed by 13 trotting trainers, and 1895 horses of other breeds, totaling of 2646 equine individuals (5.29% of the total equine population in Hungary today). The survey delivered identified 29 different types of compulsive behaviors within a total of 217 cases of stereotypic behavior. Of the 29 different of compulsive behavior, 8 types of stereotypic/ARBs were associated with feeding management. Based on survey data, 90% of Thoroughbreds spent their time in a combination of a stable and corral, and 10% of them had an access to pasture. For the Trotting population, 93% trotting horses lived in the combination of a stable and corral, and 7% of them had an access to a pasture. For other horse breeds, 19% lived exclusively in a pasture without a stable or corral, 48% spent their life in a combination of a stable, pasture and corral, 11% shuttled between a stable and pasture, 15 % were housed in a stable and corral, and 7% commuted between a pasture and corral. The Pearson-correlation method revealed a positive correlation between prevalence of ARBs and use of a stable (0.261), as well as a corral (0.286). The prevalence of ARBs correlated negatively with the use of pasture (-0.099). Thoroughbreds exhibited the highest level of prevalence of compulsive behaviors with 75 cases recorded and 34.56% of Thoroughbreds affected. Trotting horses followed with 60 cases, affecting 27.65% of the population. There were 35 cases among the miscellaneous breeds (16.13% of their population). Arabian breeds had 15 cases reported with a prevalence of 6.91%. There were 11 cases in Huculs, for a prevalence of 5.07%, and Gidrán and Hungarian warmblood breeds both had 6 cases with a prevalence of 2.76%. The Furioso-north star breed had 5 cases with a prevalence of 2.30% and the Lipizzaner had 4 cases with a prevalence of 1.84%. Compulsive behaviors and problematic activities associated with feeding occurred in 117 cases are responsible of 53.90% of total of stereotypic behaviors reported. Other compulsive behaviors were spread across 100 cases, comprising 46.10% of the ARBs reported. ARBs of intonation and pawing when feeding are the most common in prevalence (24.88%), followed by weaving (7.38%), wall-kicking (5.99%), prancing and crib-biting (5.07%) and stall-walking (4.61%). The ratios of stress-sensitivity of the population (SSP) and stress-sensitivity of the breed (SSB) can be calculated given these data. The most common equine ARBs are associated with management systems. By introducing pasture, the occurrence of ARBs can be significantly decreased. In the light of the results, the components of professional care for equids can be redefined.

Description:

Modern lactating sows have an increased demand for nutrients for the large litter size compared to the traditional genotypes. Glycerol is considered to be a good alternative to moderate the energy deficiency and provide energy supply in the feed of lactating sow. The aim of our study was to evaluate the effect of a liquid “feed grade” glycerol source on the milk production and milk composition of sows including its fatty acid profile, on the major physiological indicators of sows, and on the digestibility of nutrients. The trial was conducted with Danish Landrace×Danish Yorkshire (323±17.0 kg) sows (n = 12/treatment) and their litters. 5% glycerol supplementation increased the milk yield on d 21 of lactation [control (C): 8.94±2.27 kg/d vs. 5% glycerol (G): 10.39±1.56 kg/d; P<0.05], but had no effect on the milk production of the total lactation period (P>0.05). Glycerol inclusion decreased the milk protein content on d 14 and d 21 and had a decreasing effect on the milk protein (CP) content in the total lactation period, either (C: 5.33±0.40 g/100 g milk vs. G: 5.15.±0.33 g/100 g milk; P<0.05). Glycerol supplementation did not influence the dry matter (DM), ether extract (EE) and lactose content. 5% glycerol did not have any effect on the feed intake, live weight, back-fat thickness, and weaning-to-oestrus interval of lactating sows and neither did significantly influence the weaning weight of the piglets. There was no difference between control and experimental groups in total protein, albumin and triglyceride concentration of blood samples of sows and in the activity of liver enzymes (ALT, AST, GGT), but there was a tendency (P<0.10) for increased plasma glucose (C: 4.94±0.29 mmol/L vs. G: 5.17±0.55 mmol/L) and cholesterol (C: 2.10±0.27 mmol/L vs. G: 2.34±0.33 mmol/L) in the experimental group. Due to the 5% glycerol supplementation, the ratio of total saturated fatty acids (SFAs) of the milk fat decreased (C: 43.47±3.37 g/100 g fatty acid vs. G: 39.39±4.51 g/100 g fatty acid; P<0.05). In the SFAs group the ratio of C14:0 and C16:0 fatty acids decreased significantly compared with the control group (P<0.05). In contrast, there was a tendency for increased total monounsaturated fatty acids (MUFAs) content of the milk (C: 43.62±2.54 g/100 g fatty acid vs. G: 47.11±4.29 g/100 g fatty acid; P<0.10) but the total polyunsaturated fatty acids (PUFAs) content was not affected (C: 12.88±1.23 g/100 g fatty acid vs. G: 13.50±0.64 g/100 g fatty acid;). The total n-3 PUFAs proportion in the milk increased (C: 0.63±0.06 vs. G: 0.68±0.05; P<0.05). No differences were observed in the apparent total tract digestibility of DM, CP, EE and crude fiber between control and experimental groups. Our findings have shown that 5% “feed grade” glycerol can be fed with lactating sows without having a negative effect on the performance. Additional dose trials are needed to be performed in order to further study the effect of glycerol supplementation on milk production and on metabolic processes of lactating sows.

Page Range: 573-586

Description:

Twenty-eight warmblood mares were monitored during their late pregnancy in the Teaching Hospital of Ghent University. The reliability of two commercial assays (enzyme immunoassay and glutaraldehyde coagulation test) used for determining the IgG concentrations of their newborn foals was tested. Mammary secretions were examined at the time of foaling (T0), and then 4 (T1) and 8 (T2) hours after foaling by refractometry and electrophoresis. The foals' blood IgG levels were measured at T1 and T2 as a routine clinical diagnostic examination using two different commercial test kits (SNAP Foal Ig and Gamma-Check E) and T0, T1 and T2 samples were stored (at -18 °C) for immunoglobulin (Ig) determination by electrophoresis. Differences between the results of refractometry and electrophoresis occurred in 27.8% of the colostrum analyses. Some serum IgG could be detected immediately post partum (T0) in 75% of the foals, and 42.82% of the newborn foals acquired a serum concentration of more than 800 mg/dl IgG within 8 h of birth. Compared to the electrophoresis, the glutaraldehyde test scored better (85%) than the enzyme immunoassay (74%), although both are accurate and safe to use since they clearly distinguish between safe and unsafe IgG concentrations.

Publication Name: Tierarztliche Umschau

Publication Date: 2017-10-01

Volume: 72

Issue: 10

Page Range: 378-386

Description:

This review is an attempt to show the worldwide ectoparasitic burden in deer and antilopes with the aid of some case samples. Animals kept in zoos, lodges/ breeding farms and also in the wild, can considerable suffer and die under the burdens of parasites. The environment plays at this certainly an important role, too. Grooming and mutulism (a symbiotic relationship between two species of organism where both organism benefit from the association), vegetation and climate are only some of these factors. Not least, it should be also mentioned, that certain diseases, which can be transferred by parasites, can not only have intraspecific, but also extraspecific transmission possibilities.
