The aim of this study was to determine the prevalence of infection with F. magna flukes in roe deer from the conifer forest Bory Zielonogórskie. Parasitological dissection was performed on 20 roe deer hunted in May 2016. Faecal samples from the animals were examined by the decantation method. One roebuck was verified to be infected with F. magna, which yielded a prevalence of 5%. We noted fibrinous deposits on the diaphragmatic surface of the liver with adhesions to the diaphragm, as well as five dark-coloured nodular protrusions on the liver surface. In the cross section view of the infected liver, we saw five pseudocysts corresponding to the nodular protrusions observed on the liver surface. Three of the pseudocysts were filled with dark brown liquid containing a few flukes, their eggs and cell detritus. The other two pseudocysts contained dark fluid and fragments of dead flukes. Although, no liver fluke eggs were detected in the faeces, thousands of eggs were found in the pseudocysts. Previous studies in Poland revealed two foci of this parasitosis: in south-western and south-eastern parts of the country. It is possible that the range of both foci is expanding due to red deer migrations and the spread of infected water snails and larval forms of the parasite in watercourses and rivers. Fascioloides magna infection is a threat for cervids and domestic ruminants. Therefore, it is important to monitor the occurrence of this fluke in Poland. It is essential to determine the range of fascioloidosis, examine the intermediate host species and record cases of F. magna infection in domestic ruminants..

Long Term Survey

Summary Fascioloidosis of wild and domestic ruminants is caused by giant liver fluke, Fascioloides magna (Trematoda; Fasciolidae). In Slovakia, the parasite is present in the Danube floodplain forests permanent focus for almost 30 years. Here we provide data on 11-year survey of F. magna acquired from 137 red deer (Cervus elaphus) hunted in the southwestern hunting grounds (districts Komárno and Dunajská Streda). Almost 47 % of all examined deer, including males, females and fawns, were infected with F. magna. During the studied period, the prevalence ranged between 33.3 % (2009) and 63.6 % (2007). Prevalence of fascioloidosis varied between sexes and age categories; while the lowest overall prevalence was detected in females (33.3 %), higher values were documented for red deer males (50.6 %) and fawns (43.3 %). A presence of giant liver fluke in studied regions of southwestern Slovakia deserves future attention and ongoing monitoring due to a possible threat of F. magna infection of domestic ruminants in overlapping regions.

SummaryThe aim of the study was monitoring of liver flukes in wild ruminants including red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama) and mouflon (Ovis musimon) in selected regions of Slovak Republic. Between 2014 – 2016 we examined 782 faecal samples from selected wild ruminants using coprological techniques and serological methods (ELISA detection ofF. hepaticacoproantigens). None of the samples was positive for the presence ofFasciola hepatica, 5.89 % of faecal samples were positive forDicrocoelium dendriticum. Higher prevalence was recorded in mouflon (30.83 %), lower in red deer (1.49 %).D. dendriticuminfection was not determined in fallow deer and roe deer. The seasonal distribution of dicrocoeliosis indicated a highest prevalence in autumn. Significantly higher prevalence was recorded in fenced rearing when compared with open hunting grounds, suggesting that animal agglomeration, constant use of the same areas and possible stress are the main risk factors. Parasitological examination of livers of hunted wild ruminants revealed dicrocoeliosis in mouflon.

Giant Liver Fluke

AbstractThe giant liver fluke, Fascioloides magna, is a veterinary important liver parasite of free living and domestic ruminants. This originally North American parasite was introduced along with its cervid hosts to Europe where it has established three permanent natural foci - in northern Italy, central and southern parts of the Czech Republic and the Danube floodplain forests. The first record on fascioloidosis in Poland originated from the Lower Silesian Forest in south-western Poland and since then an occurrence of F. magna in this country has not been documented. Recently, the parasitological examination of red deer (Cervus elaphus elaphus) from the Lower Silesian Wilderness (south-western Poland) revealed the presence of F. magna eggs. In order to determine the genetic interrelationships of the Polish giant liver fluke individuals, they were molecularly analyzed by mitochondrial cytochrome c oxidase subunit I (cox1) and nicotinamide dehydrogenase subunit I (nad1) and compared with haplotypes of so far studied European populations of the parasite. The study revealed the genetic uniformity of F. magna specimens from Poland with part of individuals from the Czech natural focus.Note: Nucleotide sequence data reported in this paper are available in the GenBank

AbstractThirty-one faecal samples were collected from red deer in the northern area of Varese, in the Italian region of Lombardy, between August and October 2008. The animals had either been hunted or accidently killed. Examination for internal parasites showed a prevalence of 45.2% for Elaphostrongylus cervi larvae and species identification was confirmed by polymerase chain reaction (PCR). Ninety-seven faecal samples were also collected from two goat flocks grazing in the same area between December 2007 and May 2008. These showed a prevalence of 74.7% for lungworms. Furthermore, the central nervous systems from five goats and one sheep from this area with a history of neurologically related lameness were examined. Histopathology confirmed E. cervi cerebro- spinal nematodiasis in five cases out of six. This study demonstrates E. cervi transmission from wild to domestic ruminants when the animals graze in the same area, and the possible occurrence of clinical disease in infected goats and sheep associated with high prevalence in deer.

Abstract Introduction: The giant liver fluke, Fascioloides magna, has spread across Europe over the years posing a serious threat to the Polish cervid population. Material and Methods: Macroscopic and histopathological studies of the liver of 22 roe deer (Capreolus capreolus), 10 red deer (Cervus elaphus), and 6 fallow deer (Dama dama) were performed. Species determination of the recovered liver flukes and eggs was performed by PCR protocol amplifying fragments of ribosomal DNA (ITS2), according to a standard method. Results: The presence of F. magna was confirmed in three (13.6%) roe deer, seven (70.0%) red deer, and two (33.3%) fallow deer. The fluke eggs were found only in the stools of five red deer and one fallow deer. Conclusion: This study presents detailed pathological and histopathological changes in the liver of wild Polish cervids, including roe deer, which were subjected to such study for the first time. The hepatic lesions typical for different stages of liver cirrhosis varied depending on the host species and stage of the disease.

SUMMARYOccurrence ofYersiniaspp. in wild ruminants was studied and the strains were characterized to get more information on the epidemiology of enteropathogenicYersiniain the wildlife. In total, faecal samples of 77 red deer, 60 chamois, 55 roe deer and 27 alpine ibex were collected during 3 months of the hunting season in 2011. The most frequently identified species wasY. enterocoliticafound in 13%, 10%, 4% and 2% of roe deer, red deer, alpine ibex and chamois, respectively. Interestingly, oneY. enterocoliticaO:3 strain, isolated from an alpine ibex, carried the important virulence genes located on the virulence plasmid (yadA andvirF) and in the chromosome (ail,hreP,myfA andystA). Most of theY. enterocoliticastrains belonged to biotype 1A of which 14 wereystB positive. Further studies are needed to clarify the importance of alpine ibex as a reservoir of pathogenicY. enterocolitica.

Abstract The study was conducted in 2012-2013 on 75 fecal samples of red deer from the Lower Silesian Wilderness which were examined to determine the prevalence of Fascioloides magna in the game population. Finding liver fluke eggs in a single sample which were larger in size than Fasciola hepatica eggs indicated that further molecular analysis was necessarily. The partial sequence (116 bp long) of ITS-2 of the investigated eggs was identical to the sequences of F. magna from red deer (Cervus elaphus) (GenBank, EF534993; GenBank, EF534992) and from wapiti deer (Cervus elaphus canadensis) (GenBank, EF534994) from Slovakia, as well as from fallow deer (Dama dama) from the USA (GenBank, EF051080). This is the first molecular confirmation of the occurrence of F. magna in Poland.

Damages And Losses

This is the first study offering insights into the prevalence of giant liver fluke in the population of red deer in the territory of Serbia. Giang liver fluke (Fascioloides magna, Bassi, 1875) is the most important liver parasite among wild ruminants in Europe, especially in the region of floodplain forests along the upper watercourse of Danube river. The main objective of this research was establishing the prevalence of giant liver fluke in the region of floodplain forests of northern Serbia. In the observed regions (hunting grounds), the population prevalence rates ranged from 0 to 80% with an average prevalence in positive herds being 70.6%. The total population of red deer, from the observed hunting grounds, exposed to the giant liver fluke includes 47.9% of red deer population in Serbia, which is 0.7% of the total hunting area of Serbia. Giant liver fluke is present in north-western regions of Serbia in a narrow area of floodplain forests along the watercourse of Danube and Sava rivers next to the border with Croatia. The red deers populating the wetland basin of “Gornje Podunavlje” migrate freely through the tri-border area of Hungary, Croatia and Serbia making a consistent epizootical unit. Moreover, the game migrates freely between Croatia and Serbia in the area of Posavina forests along the river Sava. All data obtained in this research are essential for further activities aimed at preventing the spread of this parasite within red deer population and thus decreasing consequent damages and losses.

The Impact

<p>The long-term population dynamics of the red deer (<em>Cervus elaphus</em> L.) and European roe deer (<em>Capreolus</em> <em>capreolus</em> L.) at the mountain and forest zone of Crimea during 1980-2017 is presented. Fluctuations in numbers of both species are cyclical and partly synchronous. Period of oscillations in the population of red deer is about 25 years, the average duration of the oscillation period of number of roe deer is 12.3 years. During the fluctuations in the number the increasing and fall in population number of the red deer had been as 26-47 %, and roe deer – as 22-34 %. Basing on the dada obtained we have assumed that together with large-scale cycles of fluctuations in population number of both red deer and roe deer the short cycles of fluctuations in the number of these species with period from 3.5 to 7.5 years take place. Significant differences of the parameters of cyclical fluctuations in the number of roe deer at some sites of the Mountainous Crimea: breaches of synchronicity, as well as significant differences in the duration of cycles are revealed. The greatest deviations from the average values of parameters of long-term dynamics of the number of roe deer in Crimea are noted for groups of this species at two protected areas. At the Crimean Nature Reserve the cycle time of fluctuations of the numbers of roe deer was 18 years. At the Karadag Nature Reserve since 1976 we can see an exponential growth in number of roe deer that is continued up to the present time. By 2016 the number of roe deer reached 750 individuals at a density of 437 animals per 1 thousand ha. Peculiarity of dynamics of number of roe deer at some sites proves the existence in the mountain forest of Crimea several relatively isolated groups of deer. We assumed that "island" location of the Crimean populations of red deer and European roe deer, their relatively little number and influence of permanent extreme factors of both natural and anthropogenic origination have contributed to a mechanism of survival of these populations. The elements of such a mechanism include the following features of long-term dynamics of the population: the reduction in the period of cyclic population fluctuations, while maintaining their amplitude and the appearance of additional small cycles, providing more flexible response of the population to the impact of both negative and positive environmental factors. From the totality of the weather conditions for the Crimean population of roe deer the recurring periods of increases and downs in the annual precipitation amount may have relevance. There was a trend of increase in the roe deer population during periods of increasing annual precipitation.</p>
