Abstract
Setaria tundra is a filarioid parasite occurring in the northern hemisphere. Adult forms of helminths are located free in the peritoneal cavity of its definitive host - cervids, while microfilariae are presented in the host's bloodstream. Intermediate hosts are represented by several mosquito species, mainly of the genus Aedes.Nematode S. tundra is well adapted to roe deer (Capreolus capreolus) and therefore is the infection usually asymptomatic. In this study we present the first report of S. tundra in Slovakia. During a period 2022 a total of 6 roe deer coming from eastern Slovakia (Trebišov district) were examined. Nematodes were found during the evisceration process in the abdominal cavity of 3 specimens Intensity of infection was in range from 5 to 38 helminths per host. Mean intensity of infection reached 18.3 parasites per host. The helminths were identified as S. tundra by morphological examination and molecular typing of the COI gene. This study is the first report of S. tundra in Slovakia.

Abstract
Aujeszky disease (AD) or pseudorabies is a viral disease of domestic and wild animals caused by the Suid alphaherpesvirus 1. In wild boar infection usually undergo latent phase but under certain conditions reactivation of the virus can result in a disease. Seroprevalence in wild boars ranges from 0.8 to 100%, and is among other influenced by region, type of management, age and sex of the studied animals. In this study we analyzed blood, lungs, olfactory bulbs and spleen from 222 free-living wild boars from different localities in Croatia and compared results obtained by ELISA with PCR, sex, age and locality. Total seroprevalence was 33.78%, ranging from 25.26% in males to 40.15% in females (p = 0.0346; χ2 = 4.47). According to the age categories prevalence was 10% in offspring, 27.53% in subadults, and 66.75% in adults. Seroprevalence in adult males (66.66%) and females (65.30%) was almost identical. In males, significantly lower seroprevalence was detected in offspring compared to subadults (χ2 = 4.07, p < 0.05) and adults (χ2 = 31.04; p < 0.05), and in subadults compared to adults (χ2 = 15.13; p < 0.0001). Among females, adults had a significantly higher prevalence compared to offspring (χ2 = 19.27; p < 0.0001) and subadults (χ2 = 8.62; p < 0.01). Analysis between counties revealed Sisačko-moslavačka county as a hot-spot for AD. None of the samples was positive for ADV antigens. The observed trend in prevalence points to the fact that the main transmission occurs during one part of the year (most probably the mating season). Also, triggers for virus reactivation might be more complex than previously thought, since none of our samples, collected during the mating and hunting season, was PCR positive. Finally, we can conclude that adult males represent the main transmission link between different wild boar groups.

Abstract
Human induced translocation and introduction of species have reshaped parasite fauna on a global scale. The introduction of the large American liver fluke Fascioloides magna from North America to Europe is an example of an invasive alien parasite causing significant ecological and economic damage. Recent genetic studies have shown that F. magna was introduced to Europe on multiple occasions forming three permanent foci of infection. This study primarily focuses on the poorly researched genetic structuring of F. magna flukes originating from Croatia and Serbia. Additional samples from USA and Italy are also included, thereby providing novel insights into F. magna's biogeography. Partial cox1 and nad1 genes were amplified from 216 F. magna flukes extracted from red deer, roe deer, fallow deer, white-tailed deer and wild boar. Seven cox1 and nine nad1 haplotypes were identified, of which two cox1 and four nad1 haplotypes have not been not previously found. Our analysis has expanded the knowledge about possible sources of F. magna introduction to Europe, by identifying a cox1 haplotype shared by flukes from the north-eastern parts of the USA and Italy and another cox1 haplotype shared by flukes also from north eastern parts of the USA and the Danube floodplains.

Abstract
This study aimed to investigate the fatty acid (FA) composition of edible dormouse m. biceps femoris in both sexes. More than 20 FA were identified in the muscle, with the 18:1cis-9 (oleic acid) being the most abundant in both sexes, comprising more than 50% of total FA in muscle. The most dominated FA were monounsaturated (MUFA), followed by saturated FA (SFA) and polyunsaturated FA (PUFA), reaching 54.8%, 25.43% and 19.8% of total FA, respectively. Sums of PUFA and n-3 PUFA tended (p > 0.05) to be higher in males than in females. There were no significant differences between sexes on the FA composition. Nevertheless, the 18:2n-6 tended to differ between sexes (p = 0.063). Several long-chain PUFA (LC-PUFA) were detected in dormouse muscle, with the 20:4 n-6 (arachidonic acid, AA) and the 22:6 n-3 (docosahexaenoic acid, DHA) being the most abundant in both sexes. The relatively high stearoyl-CoA desaturase (SCD) indexes and the large concentration of 18:1cis-9 in dormouse muscle tissues might point to a low mobilization of the SCD products. Furthermore, finding the unusual FA 20:3 ∆5,∆11,∆14, suggests feeding on leaf and wood lipids of Coniferophytes. We demonstrated sexual size monomorphism in edible dormouse. The literature regarding the composition of dormouse meat is scarce and no studies reported the FA composition of muscle, thus, this work can contribute to increasing the knowledge on edible dormouse physiology and nutritional traits.

Abstract
Rotavirus A (RVA) is an important pathogen for porcine health. In comparison to humans, RVA in domestic animals and especially in wildlife is under researched. Therefore, the aim of the present study was to investigate the prevalence, genetic diversity, molecular epidemiology and interspecies transmission of RVA in domestic pigs and wild boars. During the three consecutive RVA seasons (2018–2021) we collected 445 and 441 samples from domestic pigs and wild boars, respectively. Samples were tested by real-time RT-PCR, and RVA-positive samples were genotyped in VP7 and VP4 segments. Our results report an RVA prevalence of 49.9% in domestic pigs and 9.3% in wild boars. Outstanding RVA genetic diversity was observed in VP7 and VP4 segments, especially in domestic pigs exhibiting a striking 23 different RVA combinations (G5P[13] and G9P[23] prevailed). Interspecies transmission events were numerous between domestic pigs and wild boars, sharing G3, G5, G6, G9, G11 and P[13] genotypes. Furthermore, our data indicate that such transmission events involved even bovines (G6, P[11]) and, intriguingly, humans (G1P[8]). This study contributes to the basic knowledge that may be considered important for vaccine development and introduction, as a valuable and currently missing tool for efficient pig health management in the EU.

Abstract
Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of infectious enteritis called paratuberculosis that has a high economic impact on the worldwide livestock production. A central important question arises: Can wildlife animals serve as a reservoir for transmission of MAP to domestic ruminants? With this in mind, we devised a study to detect MAP in various Slovakian wildlife species found in the areas where paratuberculosis had been documented in domestic ruminants. The samples of parenchymatous organs (intestines, ileocecal valve and mesenteric lymphatic nodes) from 83 wildlife animals representing 13 species, inclu- ding 7 herbivorous, 5 carnivorous and 1 omnivorous species were collected during a four-year period. The clinical and pathological examinations failed to demonstrate any manifestations of paratuberculosis in any of the wildlife samples. The detection of MAP was done by widely used tests, i.e. cultivation and the PCR analysis. The bacterial cultures revealed the growth of Mycobacterium spp. colonies in 58 (70%) of all of the wild animals, but the PCR testing demonstrated paratuberculosis only in one (7.69%) of the roe deer population.

Abstract
Liver fluke, Fascioloides magna, is an important non-native parasite introduced to Europe, posing a threat to survival of local wildlife populations. The aim of this study was to assess the serum and liver protein profile of control and F. magna infected wild boars, by means of shotgun tandem mass tag - based quantitative high resolution proteomics approach. In serum, 4 differentially abundant proteins were found out of total 1073 identified, while in liver from 3520 identified proteins, 116 were differentially abundant between healthy and F. magna infected wild boars. Pathway analysis revealed that most of the proteins differing in abundance are involved in metabolism, biological oxidations, cellular responses to stimuli, fatty acid metabolism, and others. Validation of proteomic results was performed for paraoxonase-1, ceruloplasmin, glutathione S-transferase and liver enzymes by ELISA and automated assays. Complementary analysis of liver and serum in F. magna infection enabled insight into changes of proteome profile of the host at local and sistemic level. Our findings showed that chronic infection with F. magna is associated with immune response in host, oxidative stress and metabolomic changes in liver. SIGNIFICANCE: Liver fluke infections are recognised as worldwide neglected diseases with considerable veterinary and public health importance. Pathological changes, clinical signs and outcome of F. magna infection are strongly related to the type of final hosts and their different tolerance to infection. In order to gain insight into host-parasite interactions in wild boars, dead-end host for F. magna, we assessed proteomics profile of serum and liver of control animals and those infected with F. magna. Proteomics analysis of serum and liver in parallel showed as advantageous and beneficial, demonstrating protein alterations mainly at local level. Bioinformatics analysis enabled elucidation of molecular pathways associated with F. magna infection. Identification and validation of proteins associated with infection may have added value to current tools for efficient liver fluke control.

Abstract
Tapeworms of the genus Mesocestoides (Cestoda: Cyclophyllidea: Mesocestoididae) are still enigmatic to scientists, due to their high morphological variability, low host specificity, and unknown details of their life cycle. They are found worldwide, with carnivorous mammals as the main definitive hosts, and the disease is potentially zoonotic. After ingestion by a definitive host, the tetrathyridium can occasionally migrate through the intestinal wall and reach the peritoneal cavity or abdominal organs causing peritoneal metacestodosis. Here, we report on a case of metacestodosis of a European wild cat (Felis silvestris silvestris) found dead in Croatia. At necropsy, a large number of white, rice-like structures were found free in the abdominal and thoracic cavities, as well as along the serous surfaces and in the lungs. DNA isolated from the nodules was genotyped and based on a 320-base pair long 12S fragment classified as Mesocestoides vogae. Although post-mortem changes were advanced, severe emaciation due to the severe parasitic infection and gastrointestinal bleeding was diagnosed as the likely cause of death. Intestinal cestodosis was previously reported in wild cats, but according to our knowledge, this is the first description of peritoneal and pleural metacestodosis caused by M. vogae tetrathyridia (metacestodes) in any wild carnivore species.

Abstract
Genus Setaria, Viborg 1795, comprises 46 species that parasitize in the peritoneal cavity of Artiodactyla, Perissodactyla and Hyracoidea. The majority of these infections pass unnoticed, but occasionally they can induce severe peritonitis or neurological signs in aberrant hosts and, rarely, even in humans. In this paper we describe for the first time the finding of Setaria tundra in roe deer in Croatia. We examined 45 roe deer and determined the presence of Setaria nematodes in 24.4% of samples, which were subsequently diagnosed as Setaria tundra using molecular methods.

Abstract
Deer fascioloidosis is a serious and potentially fatal disease caused by the non-native trematode Fascioloides magna. Infections of red deer with F. magna in Croatia have been reported for the first time in 2000 in the Baranja region. Subsequently, the disease spread throughout the Eastern parts of the country, involving all 3 deer species (red, roe, and fallow) and mouflons. Within the disease control programme (DCP), livers from all shot deer were thoroughly analysed and all detected trematodes and gross lesions were counted and categorized. Prevalence of positive animals, in this study for Spačva region, in the period ranging from 2007 to 2012 was 36.42% (46.39% when fawns are not considered). Epidemiological analysis was applied to evaluate risk factors and disease patterns at the population level with the aim to understand factors with negative influence on therapeutic effect. Each demographic variable was tested at the seasonal, individual and location level. Model for pathological lesions suggested that the likelihood of lesions was dependent on age (p = 0.003). We did not find any locality or sex related significant differences. Finally, environmental characteristics and migratory patterns were analysed using Geographic Information System (GIS) and showed that Spačva region represents an epidemiological unit for red deer fascioloidosis.

Abstract
The wild boar is an ancestor of the domestic pig and an important game species with the widest geographical range of all ungulates. Although a large amount of data are available on major histocompatibility complex (MHC) variability in domestic pigs, only a few studies have been performed on wild boars. Due to their crucial role in appropriate immune responses and extreme polymorphism, MHC genes represent some of the best candidates for studying the processes of adaptive evolution. Here, we present the results on the variability and evolution of the entire MHC class II SLA-DRB1 locus exon 2 in 133 wild boars from Croatia. Using direct sequencing and cloning methods, we identified 20 SLA-DRB1 alleles, including eight new variants, with notable divergence. In some individuals, we documented functional locus duplication, and SLA-DRB1*04:10 was identified as the allele involved in the duplication. The expression of a duplicated locus was confirmed by cloning and sequencing cDNA-derived amplicons. Based on individual genotypes, we were able to assume that alleles SLA-DRB1*04:10 and SLA-DRB1*06:07 are linked as an allelic combination that co-evolves as a two-locus haplotype. Our investigation of evolutionary processes at the SLA-DRB1 locus confirmed the role of intralocus recombination in generating allelic variability, whereas tests of positive selection based on the dN/dS (non-synonymous/synonymous substitution rate ratio) test revealed atypically weak and ambiguous signals.

Abstract
Alveolar echinococcosis, caused by the tapeworm Echinococcus multilocularis, is one of the world's most dangerous zoonosis and an emerging disease with growing incidence in humans. The disease has been reported in new areas and host species in the last two decades, and the primary hosts of the parasite - red fox, golden jackal and grey wolf - are expanding their distribution in Europe. Here we report the morphological and molecular identification of Echinococcus multilocularis tapeworms in one of 29 carcasses of adult golden jackals in Croatia, where the only previous report of the parasite was in red foxes in 2016. These results suggest that alveolar echinococcosis should be treated as an emerging disease in Croatia.

Abstract
Summary
Fascioloidosis is a parasitic disease of primary wild and domestic ruminants, caused by a digenean trematode, Fascioloides magna. The final hosts of F. magna are divided according to the host-parasite interactions into definitive, dead end and aberrant. The clinical appearance, pathology, outcome of disease, and its importance in disease epidemiology vary with different host types. According to this division, wild boar (Sus scrofa) are characterized as a dead end host. In this paper we analysed 12 wild boar livers from Croatia. Eleven of them contained pigment traces, pseudocysts, degrading pseudocysts, fluke migratory channels, live and degrading flukes. F. magna eggs were found in pseudocysts, but no eggs were recovered from faeces. Concurrent infection with F. magna and Fasciola hepatica was detected in one liver. According to everything we observed, wild boar currently has no direct role in maintaining and spreading the disease.

Abstract
The presence of American liver fluke (Fascioloides magna) in Croatian wild ruminant species was detected for the first time in January 2000. At the same time, the problem of adequate parasitological monitoring and treatment appeared in the captive deer population. Quarantine and health screening protocols, as well as migration and transportation influence had to be evaluated in red deer husbandry. Non-invasive methods were introduced to estimate the prevalence of F. magna in the semi-farm rearing system. Coprological analysis has been performed on 264 faecal samples. The most effective antiparasitic treatment was implemented on herd and individual treatment. Treatment was extended to the free-ranging population of deer in the same region.

Abstract
Wildlife-vehicle collisions (WVC) have increased and now there is a world-wide problem related to significant mortality of wildlife, habitat fragmentation, change in behavior and even disappearance of local endangered populations. Along with these deleterious effects on wildlife, WVC can also result in injuries and deaths of humans. During the three-year monitoring, a total of 7,495 wildlife-vehicle collisions were recorded, including mainly roe deer (73%), while other species were less frequently affected (wild boar--9%; brown hare--5%; and red deer and pheasant each with 4%). Incidence of wildlife-vehicle collisions were observed according to territorial distribution, seasonal and daily occurrence and type of road (total and per 1 km).

Abstract
Polychlorinated biphenyl (PCB) and organochlorine pesticide (OCP) levels in fat tissue of red and fallow deer (Cervus elaphus L. and Dama dama L.) from two inland and an Adriatic area were established. Of 17 analysed PCBs, PCB-28, PCB-138, PCB-153, PCB-180 and PCB-118 were found in all samples, whilst PCB-101 and PCB-170 were found in more than 50% of samples. They ranged between 0.03 and 5.98 ng g(-1) fat weight. Of seven analysed OCPs, HCB, γ-HCH and 1,1-dichloro-2,2-di(4-chlorophenyl)ethylene (DDE) were found in all samples, whilst β-HCH was found in more than 50% of samples. They ranged between 0.17 and 22.14 ng g(-1) fat weight. The dominating compounds were DDE, PCB-138, PCB153, PCB-118 and PCB-180. According to the Duncan multistage test, the levels of PCB-138, PCB-153, PCB 170 and PCB-180 were significantly higher in perirenal fat samples of specimens taken from the Adriatic area. DDE was significantly higher in the inland deer samples. Some species differences were determined and were mostly related to higher PCB and β-HCH levels in fallow deer samples and higher DDE levels in red deer samples. No sex difference was established. As for age, significantly higher levels of PCB-118 and PCB-52 were found in fawns.

Abstract
Concentrations of cadmium, lead and mercury were determined in muscle, liver and kidney tissue from three different age groups of red deer (young animals aged 6 or 7 months, middle-aged animals aged 3 to 5 years, old animals aged over 8 years) from the Baranja region of Croatia. Median cadmium concentrations were low in the muscles of all investigated age groups (0.0002; 0.0009 and 0.0020 μg/g), higher in the liver (0.0279; 0.0656 and 0.1463 μg/g) and highest in the kidneys (0.4792; 2.8531 and 6.1657 μg/g). A positive correlation was established between cadmium concentration and age. In all analyzed tissues the median lead concentration was higher in young (muscle 0.0024; liver 0.0364 and kidney 0.0618 μg/g), compared to middle-aged animals (muscle 0.0001; liver 0.0184 and kidney 0.0160 μg/g). In contrast to cadmium, mercury had a negative correlation to age but median concentrations were very low (in muscle: 0.0011; 0.0001 and 0.0006 μg/g; in liver: 0.0051; 0.0037 and 0.0022 μg/g and in kidney: 0.0145; 0.0183 and 0.0106 μg/g) especially compared to cadmium. From the hygienic point of view all the examined tissues are edible since concentrations of the analyzed metals do not exceed values proposed by the official regulations, with the exception of a few kidney samples, which contained cadmium above the recommended value. Furthermore, mercury concentrations are no longer (since 2008) a matter of legislation.

Abstract
A century ago, Thomas Hunt Morgan, the American scientist, studied the cytogenetic changes of drosophila and came to cytogenetic explanation of Mendel's basic laws of genetic heredity. These studies resulted in today's Mendel-Morgan chromosomal theory of heredity. On the occasion of the hundredth anniversary of this important discovery the authors have decided to give a review of the most significant achievements in the field of molecular genetics until the completion of the Human Genome Project. The most important points concerning the technology of DNA recombination and genetic engineering are also presented. The final section discusses the significance of previous achievements of molecular genetics in biomedicine and other related fields. There is also a tabular presentation of the sequence of the most important findings in the field of molecular genetics through time.

Abstract
Trichotecene poisoning in poultry can cause oral lesions, haemorrhages, depletion and necrosis in the lymphopoetic organs and death. Spontaneous poisonings with these toxins are rarely described. This paper describes the spontaneous poisoning of two Brahma chickens with T-2 toxin, diacetoxyscirpenol and deoxynivalenol. Two out of 10 chickens died under signs of depression and loss of appetite. Histopathological analysis revealed vacuolar dystrophy of the liver, necrosis and depletion of lymphocyte in the bursa of Fabricius as well as multiple necroses in the glandular stomach and gut. Even though quantities of 0.70 mg/kg T-2 in the food together with 0.50 mg/kg diacetoxyscirpenol significantly differ from the median lethal dose for chickens reported in literature (4.97 mg/kg), parasitological, virological and histopathological results indicate trichotecenes as the causative agents of this pathological condition.

Abstract
Intra-alveolar infraction and malformation of the apical part of the permanent left maxillary canine in an adult male wild boar (Sus scrofa L.) is documented. The infraction and its sequelae produced an irregular mass of reparative tissue that led to the formation of two growing ends of the tooth.

Abstract
The structure of teeth in all living beings is genetically predetermined, although it can change under external physiological and pathological factors. The author's hypothesis was to indicate evolutional shifts resulting from genetic, functional and other differences. A comparative study about certain characteristics of incisors in humans and myomorpha, the fat dormouse (Glis glis) being their representative as well, comprised measurements of enamel and dentin thickness in individual incisor segments, evaluation of external enamel index, and also assessment of histological structure of enamel and dentin. The study results involving dormice showed the enamel to be thicker in lower than in the upper teeth, quite contrary to enamel thickness in humans. In the upper incisors in dormice the enamel is the thickest in the medial layer of the crown, and in the cervical portion of the crown in the lower incisors. The thickness of dentin in dormice is greater in the oral than in the vestibular side. These findings significantly differ from those reported in reference literature, but they are based on the function of teeth in dormice. Histological characteristics of hard dental tissues in dormice are similar to those in humans, with exception of uniserial structure of enamel and appearance of dentinoenamel junction.

Abstract
In view of the use of synthetic propentofylline (PPF) as a protective agent in brain ischemia, its possible side effects on vision capacities have been explored by electroretinography in comparative experiments with theophylline. We used eyecup preparations of small-spotted dogfish sharks and of European eels, particularly suitable for long-lasting experiments. The drug exerted profound but reversible modifications of ERG records: (1) a dose-dependent increase of the amplitude and duration of the chemically isolated late receptor potential (LRP), (2) a partial unmasking of LRP, (3) a strong potentiation of the LRP-unmasking effect of low temperature, (4) a potentiation of light adaptation effects, and (5) a strong potentiation of the post-illumination hyperexcitability. The effects were explicable as due to a strong phosphodiesterase (PDE) inhibiting, cyclic guanosine monophosphate (cGMP) promoting, action of the drug. The effects were considerably stronger, or even of opposite sign, in comparison to those of the chemically related theophylline. PPF did not seriously affect the ERG c-wave originating in the pigment epithelium. The results suggested that the effects of PPF on vision may not seriously hamper the therapeutic use of the drug. They indicated, on the other hand, that PPF was a retinoactive drug of potential usefulness in the exploration of the complex biochemical events underlying visual transduction.

Abstract
1. At different levels of the holding potential on neuron R2 membrane in the Aplysia depilans abdominal ganglion, dopamine injected intracellularly increases the amplitude of both inward and outward currents recorded in response to the application of acetylcholine (ACh) to the ganglion surface. 2. The addition of dopamine to the external perfused solution produces generation of inward currents and a decrease in the cell response to the ACh. 3. The enhancing effect of injected dopamine on ACh responses is retained after inhibition of acetylcholinesterase (AChE) by a specific organophosphorous inhibitor, compound Gd-42. 4. The modulating effect of injected dopamine on ACh responses is discussed in terms of the existence of intracellular receptors of neurotransmitters in the differentiated cells.
