Abstract
The "beautiful viviparous fly", Wohlfahrtia magnifica, may have a magnificent appearance due to its striking morphology; however, it is a potentially deadly agent of obligate traumatic myiasis in humans and animals, with a serious impact on welfare and economics. The fly is found across the Palearctic realm, including the Western Balkan region, with reports from former Yugoslavian countries from the first half of the 20th century. In this paper, a recent case of wohlfahrtiosis recorded in Northern Serbia is evidenced using morphological and molecular techniques. Larvae were collected from two adult sheep with severe hoof myiasis and two young sheep with genital and interdigital myiasis. Morphological identification was performed for adults bred from the infested vulva and third-stage larvae (L3) collected from the hoof wounds, supported with barcoding sequences of the COI gene obtained from larval pairs from the hoof wounds of older and the genitalia of younger sheep. W. magnifica was identified according to the appearance of male fly terminalia and the morphology of L3, which was confirmed after the comparison of representative sequences of the COI gene (deposited in GenBank™ under accession numbers MT027108-MT027114) to those available in GenBank™. This finding represents the first reported case of wohlfahrtiosis in the Western Balkans in 80 years, highlighting the need to re-inform relevant stakeholders to achieve adequate disease control.

Abstract
PURPOSE Data on gastrointestinal infections in horses in Southeastern Europe are limited; thus, this study aimed to add to the existing knowledge on this topic by reporting on the prevalence of intestinal parasites of horses in the territory of the Republic of Serbia. METHODS In the period from April 2017 to December 2018, parasitological examination of 548 samples from horses of different breed, age and sex from four regions and 18 districts of the country was performed. Coprological diagnostic was done by using qualitative methods without concentration and qualitative methods with concentration of parasitic elements. Quantification of the obtained results was performed using semi-qualitative faecal egg count. RESULTS Four helminthoses were detected in the examined samples: P. equorum (8.57%), O. equi (3.65%), strongylid eggs (71.17%) and Anoplocephala spp. (0.91%). The total prevalence of helminthoses was 77.19%. Monoinfections were significantly more present 70.07% compared to coinfections (7.12%). The highest prevalence of helminthoses was detected in free-ranging horses (93.10%-27/29), in autumn 86.67% (117/135) and winter 79.71% (165/207), in Šumadija and West Serbia region (100%), and in the youngest category (100%). Significant difference (p < 0.001) was detected in the prevalence of monoinfections by strongylids and O. equi and also coinfections by strongylid/P. equorum between horses of different age categories. CONCLUSION Obtained results are of great contribution to clinical parasitology and pathology, especially from the aspect of animal health, welfare and preservation of horse population.

Abstract
Dirofilariosis and leishmaniosis are severe parasitic diseases in dogs, and their causative agents can also be pathogenic to humans. In this study, we conducted a multicentric survey in the regions of Serbia and North Macedonia with the goal to establish an epidemiological scenario of dirofilariosis and leishmaniosis in the territory of Central Balkan. Using molecular analyses, a total of 535 dogs from Northern Serbia (NS), Southern Serbia (SS) and North Macedonia (NM) were screened for the presence of Dirofilaria spp. and Leishmania spp. We confirmed that Central Balkan is an endemic region for Dirofilaria (D.) immitis, as it was found to be the dominant species in this area, with the highest prevalence of 8.75% in NM, followed by NS (6.68%) and a significantly lower prevalence in SS (1.51%). Two dogs (2.5%) from NM were positive for Leishmania (L.) infantum infection. None of the dogs from Serbia tested positive for Leishmania spp. High prevalence and dominance of D. immitis species, and the rising threat of L. infantum spread to the territory of Serbia, suggest that preventive measures are of a great necessity to combat the spread of these vector-borne zoonoses.

Abstract
Data on endoparasitic infections in dogs from dog shelters in Southeastern Europe are limited; thus, this study aimed to add to the existing knowledge on this topic by reporting on the prevalence of intestinal parasites in dogs from public dog shelters in the Republic of Serbia. In 2017 and 2018, individual and pooled fecal samples, were collected from 1267 dogs from six shelters. All samples were qualitatively examined for parasites using flotation tests. Seven taxa of intestinal parasites were identified: Cystoisospora spp., ascarids: Toxocara canis and Toxascaris leonina, hookworms, Trichuris vulpis, taeniids and Dipylidium caninum. The overall prevalence of intestinal parasites was 58. 3 % (78. 1 % in young dogs and 53.1 % in adult dogs). The parasites detected in both young (<1 year old) and adult dogs (>1 year old) were Cystoisospora spp. (20 % and 4.9 %), T. canis (33.5 % and 14.7 %), T. leonina (7.7 % and 2.3 %), and hookworms (16.9 % and 15 %), respectively. However, T. vulpis (9.6 %), taeniids (1.3 %), and D. caninum (5.4 %) were detected only in adult dogs. In the Belgrade shelter, young dogs had a higher prevalence of endoparasitic infections (18.9 %, 49/260) than adult dogs (14.8 %, 149/1007). In the Subotica, Jagodina and Niš shelters, young dogs had significantly higher (p < 0.001 and p < 0.05, respectively) prevalence of endoparasitic infections (10 %, 12.3 % and 14.6 %) than adult dogs (5.3 %, 8 % and 7.2 %). These results will be useful for establishing health care programs in dog shelters and implementing effective strategies for the control of intestinal parasites.

Abstract
In the last decade, as the result of climate changes, there have been considerable changes in the parasitofauna of domestic and wild carnivores. The prevalence of the existing parasitic species has varied significantly, showing an increasing tendency, and some parasitic species not present before in this epizootiologic territory have been diagnosed as well. It is thought that the reason for such an epizootiological situation is increased presence of owners with their pet animals in the regions endemic for particular zoonotic helminthoses during summer holidays and touristic visits. This tendency has become especially conspicuous in the last several years characterized by warm winters and very hot summers due to global warming effects, with abundant atmospheric precipitation. Oral vaccination of foxes against rabies, regulated in Serbia by appropriate laws since 2010, has led to an increased number of foxes and rise of prevalence of the parasitic diseases for which foxes represent the infection source/reservoir. Continued urbanization of Serbian cities, with the extension of urban belts into the suburbia and recreational (“weekend”) settlements, lead to a closer contact of street dogs and owned dogs with foxes, which results in a significant change in the parasitic fauna of dogs. It is an additional factor, which in the chain fox - street dog - owned dog - human increases the risk and tendency for the occurrence of human infections with zoonotic endoparasites of wild and domestic carnivores. In order to reliably predict the degree of spread of particular zoonotic helminthoses in particular regions in Serbia, for which wild carnivores represent the infection source, it is necessary to institute continued monitoring of the parasitic fauna in this type of wild animals.

Abstract
The aim of this study was to investigate the genetic diversity of Varroa destructor parasitizing Apis mellifera colonies and to test for possible host-parasite association at the mitochondrial DNA (mtDNA) level. Six A. mellifera haplotypes (including a novel C2aa) and five haplotypes of V. destructor were detected in 29 analyzed colonies from eight sampling sites in Serbia. We revealed the presence of the K and S1 haplotypes as well as KS1 and KP1 heteroplasmic mite individuals in all localities, while the P1 haplotype was only found in four sampling sites. Significant differences in V. destructor genetic diversity were found at both apiary and colony levels, with mite haplotypes coexisting in almost all tested colonies. In addition, a significant correlation between the number of analyzed mites per colony and the number of identified V. destructor haplotypes was observed. However, no significant host-parasite relationship was found, suggesting that mites bearing different haplotypes as well as those heteroplasmic individuals are well adapted to the host, A. mellifera, independently of the identified haplotype present in each colony. Our results will contribute to future population and biogeographic studies concerning V. destructor infesting A. mellifera, as well as to better understanding their host-parasite relationship.

Abstract
This report represents the prevalence of endoparasitic infections of birds in zoological gardens in Serbia. Coprological examination conducted during 2015 and 2016, involved samples from 318 individual birds belonging to 112 species, in three zoo gardens (Belgrade, Palić and Bor). Individual faeces samples were analysed by the flotation method in salt solution. The presence of endoparasites was established in 51.96% (Belgrade), 46.16% (Palić) and 16.66% (Bor) of the tested birds. We diagnosed coccidian oocysts, eggs of Capillaria spp, Heterakis spp, Trichostrongylus spp, Ascaridia spp, Syngamus trachea and eggs of yet unidentified trematode. There were no detection of parasites from the class of cestodes. Prevalence of infection with coccidia, depending on location, was in the ranges between 8.33% and 32.84%, capillariosis 2.77% and 29.41%, heterakiosis 2.56% and 12.74%, trichostrongylidosis 5.55% and 25.64%, askaridiosis 10.25% and 10.78%, syngamosis 2.94% and trematodes of unknown etiology 2.45%. Coinfections with two or three parasitic species were detected in Belgrade and Palić Zoo Gardens, while quadruple infection was established in birds of Belgrade Zoo Garden. Obtained results can be used in establishing programs for health protection of endangered bird species.

Abstract
In the present study, amplification refractory mutation system (ARMS) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods were used for identification of recently described Serbia 1 (S1) and Peshter 1 (P1) mitochondrial haplotypes of Varroa destructor. Based on single nucleotide polymorphisms (SNPs) within cytochrome oxidase 1 (cox1) and cytochrome b (cytb) gene sequences, a total of 64 adult V. destructor females were analyzed from locations where the S1 and P1 haplotypes had been detected previously. Results of haplotype identification obtained by ARMS and PCR-RFLP methods were completely consistent with the sequencing data. Furthermore, in some analyzed samples the occurrence of site heteroplasmy at haplotype-defining sites was detected, as it was confirmed by double peaks in the sequence chromatograms. Neither mites with simultaneous nucleotide variability, nor those with combined SNP and heteroplasmy in cox1 and cytb were found. Given that this is the first occurrence of site heteroplasmy in V. destructor, the origin of this phenomenon and possible specific traits of heteroplasmic mites have yet to be determined.

Abstract
Abstract
Blood smears stained with Diff Quick are the initial tool for cytological diagnosis of Haemogregarina spp. However, the development of sensitive and specific molecular methods enabled the detection and identification of parasites in the sample and to clarify the evolutionary relationships of adeleorinid parasites within the Apicomplexa.
The current study was attempted in order to perform cytological investigation and molecular identification of the hemoparasites in thirty European pond turtles (Emys orbicularis) from the quarantine section at Belgrade Zoo, which have been found in poor health condition with massive skin hemorrhages, based on intraerythrocytic parasitic forms on hematological smears and 18S rDNA sequence, respectively.
Different life cycle stages of the Haemogregarina sp. were noticed within the erythrocytes in the peripheral blood. Biochemical analysis indicated lower values of AST and iron in most of the infected turtles while hematological analysis showed a changed hematocrit value, a decrease in the number of red blood cells and low hemoglobin levels. Amplifications of the 18S rDNA sequence of Haemogregarina were detected in 30/30 (100%) turtles with clinical symptoms. The identity of PCR products was confirmed by direct DNA sequencing. Future research concerning H. stepanowi in Serbia should be applied to its definitive host-the leech.

Abstract
There is a lack of appropriate data on transfer of some radionuclides on many terrestrial biota groups. To expand the available data concentration ratios of (238)U, (226)Ra, (232)Th, (40)K and (137)Cs in mosses are presented in this paper. The relationship between concentration ratios of radionuclides and physicochemical characteristics of the underlying soil was also investigated. The data on concentration ratios obtained here will provide a useful addition to the currently used database of transfer parameters, particularly for natural radionuclides.

Abstract
The study is dealing with the distribution and the origin of heavy metals (Cd, Cr, Cu, Mn, Ni, Pb and Zn) in soils from a priori non-polluted areas. Positive correlations with organic matter and clay content but not with pH have been observed for most of elements analyzed in this study. Correlations of some metals (Cr, Pb and Zn) and radionuclides (238U and 137Cs) observed for analyzed soils could be explained by their common affinity for clay minerals. Enrichment factor (EF) analysis and cluster analysis (CA) highlighted the lithogenic origin of Cr, Cu, Mn, Ni, Pb and Zn and pointed out the primary input of Cd from anthropogenic sources. It also revealed the need for detailed geochemical surveys in the future in order to decrease the uncertainty of discrimination between lithogenic and anthropogenic origin of metals of interest.
