Description:
The history of hunting customs and traditions, as well as game management, in Hungary is long and rich, forming an essential part of Hungarian culture. By the end of the 20th century, changes had been introduced to the political and social structures, as had been the case in the field of hunting. In Hungary, the right to hunt is an integral part of land ownership. Those who own land that is classified as hunting land are entitled to exercise this right. Furthermore, landowners may lease this right within the boundaries of the hunting area established by the relevant hunting authority. The lease shall be concluded by a lease contract between the parties, namely the landowner and the hunters' association. The Hungarian Parliament enacted Act LV of 1996, which modernised the decree on game protection, game management, and hunting. Furthermore, the act delineates the fundamental elements of a hunting lease contract, yet it lacks sufficient detail regarding the leasing fee. Since 1996, a method for determining the leasing fee for hunting has been lacking. This is despite the fact that there has been a need for such a method for more than 25 years. The current situation is such that the contracting parties and the public authorities are unable to determine the leasing fee for hunting in a realistic manner. This lack of clarity has resulted in disagreements between the contracting parties. Furthermore, the current situation is such that there is no accurate and useable method for determining the leasing fee for hunting. A nationwide data collection has commenced among Hungarian hunting associations, based on a literature review and the methodology. The objective is to determine which factors influence the leasing fees and to what extent. The hedonic price method, which has already proven its worth in previous similar research, has been employed to draw up a multivariate regression equation of national validity. This permits the examination of the situation in all counties, and thus the establishment of whether the leasing fee used in the leasing contract of a particular hunting ground matches its characteristics. The objective of this research is to develop a comprehensive and transparent model for the determination of leasing fees for hunting, based on a synthesis of national and international literature.

Sudden deaths of barn swallows (Hirundo rustica) caused by an invading cold front in September 2024 in Hungary
Publication Name: Magyar Allatorvosok Lapja
Publication Date: 2025-08-01
Volume: 147
Issue: 8
Page Range: 493-498
Description:
Background: The barn swallow (Hirundo rustica) is a migratory bird with a characteristic color, shiny black on the back, dirty white feathers on the belly, rust-red throat, weighing 17–20 g. This species mainly hunts flying insects, catching them in flight and the swallows are constantly hunting in the air between sunrise and sunset. As the food-scarce autumn season approaches, swallows gather in large flocks and when the daytime temperature drops permanently below 15 ºC, they leave for their wintering grounds in Africa. The birds are preparing for the migration, replenishing their body's fat depots. By the time of leaving, thebirds reach a body weight of 22–25 g, which enables them to travel thousands of kilometers. The metabolism of birds is fast, which is especially noticeable in smaller species. Shortterm starvation is already associated with a significant deterioration in nutritional status. Objectives: The carcasses of the swallows that were still alive at the time of capture, but died during transport were examined to identify to cause of sudden death. Materials and Methods: On September 16, 2024, 34 immobile and flightless swallows were delivered to the Clinic of the Department of Exotic Animal and Wildlife Medicine from the beach in Csopak, Hungary (46° 58′ 10.4″ N, 17° 56′ 13.9″ E). Five randomly selected carcasses of swallows were examined according to the standard pathological methods (dissection, histopathology, special stainings, bacteriological examination, PCR). Results and Discussion: During the dissection the body weight of the swallows delivered to the clinic was 12.0–13.0 g (12.6 g on average) which is around half of the normal bodyweight of these birds before migration. The supplementary examinations were negative for known pathogens and histopathology showed extreme lack of glycogen. According to the weather data from 11th of September 2024, a cyclone with significant cooling and heavy rainfall hit Hungary. The reason behind the death of the swallows was starvation caused by the sudden disappearance of the population of flying insects that could be caught by swallows due to cold and rainy weather. This case draws attention to the dangers of sudden extreme effects of global climate change in the case of some sensitive animal populations.

First detection of Ehrlichia cf. ewingii in a reindeer (Rangifer tarandus) in Hungary
Publication Name: Acta Veterinaria Hungarica
Publication Date: 2025-09-15
Volume: 73
Issue: 3
Page Range: 144-149
Description:
Abstract: This the first report on the presence of Ehrlichia cf. ewingii in a reindeer (Rangifer tarandus) in Hungary. The animal started to show apathy and loss of appetite and subsequently died shortly after being placed in an enclosure with dense vegetation, following a quarantine period. During the diagnostic necropsy, a large volume of reddish pericardial and thoracic effusion was observed resembling heartwater disease. Ehrlichia cf. ewingii was detected from the thoracic effusion by PCR and sequencing. The selenium content of multiple organs (liver, kidney, heart and skeletal muscles) were measured, but no increase was found. PCR tests for the detection of adenoviruses from the liver, lungs and spleen were negative. The routine bacteriological culture from the liver did not yield specific results either. To establish a causal relationship between the presence of E. cf. ewingii and the animal's death, further investigations are necessary.

Infection by SARS-CoV-2 in a rescued serval (Leptailurus serval, Schreber, 1776)
Publication Name: Acta Veterinaria Hungarica
Publication Date: 2025-11-24
Volume: 73
Issue: 4
Page Range: 228-236
Description:
In late November 2021, a male serval (Leptailurus serval) which had escaped from an unknown holding facility was observed in the Bükk Mountains of Northern Hungary. A few days were needed to capture the animal with a live trap, after which it was transported to a national Rescue Centre at the Budapest Zoo and Botanical Garden. The exact origin of the specimen was never identified and apart from being emaciated, it seemed only to be stressed and weakened by the cold weather and starvation. Contrary to the initial fair prognosis, 2.5 days after admittance, the animal rapidly developed pronounced respiratory and central nervous system signs and despite intensive treatment died within a few hours. The subsequent diagnostic investigation revealed that the cause of death was SARS-CoV-2 infection. These diagnostic steps excluded other possible, lethal felid pathogens as causative agents and confirmed that the disease process was attributed to this virus.

Pathological changes caused by myxomatosis in brown hares (Lepus europaeus)
Publication Name: Magyar Allatorvosok Lapja
Publication Date: 2025-01-01
Volume: 147
Issue: 12
Page Range: 727-737
Description:
Background: Myxomatosis appeared in wild brown hares a few years ago and was confirmed in Hungary this autumn. The disease can be caused by the classic myxomatosis virus (MYXV) that infects domestic rabbits and by recombinant (ha-MYXV) strains in brown hares, in which acute lesions localized on the skin of the head and genitals can be observed. Material and methods: In October this year, we dissected a total of 15 wild hares from several areas in Western Hungary and performed histopathological examinations of the affected organs. In our work, we compared the pathological abnormalities observed in wild and domestic rabbits with previously published data. Results and discussion: In our work, we dissected 15 hares (8 adults and 1 juvenile, a total of 9 bucks, and 5 adults and 1 juvenile, a total of 6 females). Edema of the eyelids, lesions on the mucous membrane of the eyelids, and inflammatory edema of the genitals were detected in all individuals. In 13.33% of the hare bucks, we also found subcutaneous edema accompanied by diffuse swelling of the skin of the head, which is not well known in Oryctolagus sp. However, ear lesions, which are common in domestic and wild rabbits, were significantly less frequent in brown hares (33.33%). The histopathological lesions described in cases of myxomatosis of domestic rabbits were 100% consistent with those found in wild brown hares.

Reconstruction of the type specimen of Canis lupus minor Mojsisovics, 1897 (Carnivora: Canidae)
Publication Name: Spixiana
Publication Date: 2026-01-01
Volume: 48
Issue: 2
Page Range: 217-220
Description:
Mojsisovics (1897) described the taxon Canis lupus minor based on the pelt of a canine carnivore killed in Bilje (Croatia) and made into a carpet. Although the skin’s original dimensions may have changed during preparation, the available data and description suggest that it most likely represents the fur of a golden jackal or a canine hybrid. As far as we know, the pelt has now been lost. Here, the authors, using the available information and starting from a jackal pelt, reconstructed the colouration and pattern of the C. lupus minor type specimen.

A Simplified and Efficient Protocol for DNA Isolation from Deer Antlers and Prepared Trophy Skulls
Publication Name: Animals
Publication Date: 2026-04-01
Volume: 16
Issue: 7
Page Range: Unknown
Description:
A simple, fast, and cost-effective organic solvent-based protocol was developed for DNA extraction from deer antlers and prepared trophy skulls, eliminating the need for commercial kits or cryogenic grinding. The method combines bead-based mechanical homogenization with a 4 h enzymatic digestion in EDTA buffer containing N-lauryl sarcosine and Proteinase K, followed by phenol–chloroform–isoamyl alcohol purification and centrifugal filtration. DNA quality and quantity were evaluated using agarose gel electrophoresis, Qubit fluorometry, and Nanodrop spectrophotometry. The protocol was tested on 60 samples, comprising 30 antlers and 30 pedicle parts from prepared trophy skulls of roe deer (Capreolus capreolus), fallow deer (Dama dama), and red deer (Cervus elaphus). To assess suitability for downstream applications, species-specific microsatellite markers were amplified using multiplex PCR, successfully generating complete genotypes from all 60 samples. These results, along with a demonstrated case study, confirm that the developed protocol provides high-quality DNA suitable for molecular genetic investigations, enabling reliable genotyping from small amounts of both antler and processed trophy materials in forensic and conservation contexts.
