Abstract
Parasites constitute a significant economic burden and highly impact environmental, public, and animal health. The emergence of many parasitic diseases is environmentally mediated and they share the same biogeography with humans and both domestic and wild animals. American liver fluke, Fascioloides magna - a trematode parasite of domestic and wild ungulates - is an example of the anthropogenic introduction of an "invasive alien species" in Italy and Europe. Multiple introductions to Europe have led to the biogeographical expansion of the parasite across the Danube region mainly provided by the presence of suitable habitats for all hosts involved in the parasite's life cycle, human-assisted transport, and drastic environmental events such as flooding. In Italy, it was introduced and established in La Mandria Regional Park (LMRP) near Turin in 1865 along with imported wapitis (Cervus elaphus canadensis) from North America (Bassi, 1875), but with no reported expansion to the surrounding areas. LMRP isolated F. magna focus, poses an important threat of possible expansion since the enclosed area is vulnerable to occasional bidirectional passage of roe deer. Additionally, tributary rivers to the Po river system, traversing the enclosed area, could further bolster the possibility of such spread. In this study, we developed a duplex qPCR assay for F. magna and its principal intermediate host Galba truncatula optimized for testing eDNA samples to meet the needs for surveillance of the parasite. Moreover, we validated the developed assay in natura by testing samples derived from filtered water and sediments collected inside and outside LMRP's fenced-off area. Our findings for the first time demonstrate the presence of F. magna's eDNA outside the park's internal fenced-off area.

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
PURPOSE The giant liver fluke, Fascioloides magna, is an important parasite of white-tailed deer (Odocoileus virginanus), a commercially important game species in the northeastern United States. However, the parasite has never been genetically characterized from this region and so its genetic interrelationships with other enzootic populations on the continent are unknown. The purpose of this study was to genetically characterize F. magna from the Adirondack region of northern New York (NNY) and determine its relationship with its enzootic cohorts. METHODS Flukes were extracted from seven livers of O. virginanus at three localities in and around the Adirondack Park in northern New York. DNA was extracted from eight individuals using standard procedures, and a 440-bp fragment of the COI gene was amplified using species-specific primers. F. magna sequences generated from a previous phylogeographic study were obtained from the GenBank database and a mtDNA dataset was compiled, aligned, and edited for molecular analyses. Analyses based on eight mtDNA sequences included haplotype network reconstruction, along with hierarchical and pairwise (ФST) AMOVA tests. RESULTS F. magna from the Adirondacks was found to be most genetically similar to specimens from Minnesota based on shared haplotypes and relatively low genetic differentiation (ФST = 0.331). East coast enzootic populations exhibited panmixia while their west coast cohorts were genetically distinct. CONCLUSION Based on the strong genetic similarities between F. magna from northern New York and Minnesota, we propose that the GLR enzootic range of F. magna be extended to encompass the Adirondack region of NNY.

Abstract
Many trematode parasites cause infection in humans and are thought to be a major public health problem. Their ecological diversity in different regions provides challenging questions on evolution of these organisms. In this report, we perform transcriptome analysis of the giant intestinal fluke, Fasciolopsis buski, using next generation sequencing technology. Short read sequences derived from polyA containing RNA of this organism were assembled into 30,677 unigenes that led to the annotation of 12,380 genes. Annotation of the assembled transcripts enabled insight into processes and pathways in the intestinal fluke, such as RNAi pathway and energy metabolism. The expressed kinome of the organism was characterized by identifying all protein kinases. A rough draft genome assembly for Fasciolopsis buski is also reported herewith with SRA accessions for crosschecking the findings in the analyzed transcriptome data. Transcriptome data also helped us to identify some of the expressed transposable elements. Though many Long Interspersed elements (LINEs) were identified, only two Short Interspersed Elements (SINEs) were visible. Overall transcriptome and draft genome analysis of F. buski helped us to characterize some of its important biological characteristics and provided enormous resources for development of a suitable diagnostic system and anti-parasitic therapeutic molecules.

Abstract
In last few years, a great effort has been made to understand genetic interrelationships of European and North American populations of giant liver fluke Fascioloides magna (Trematoda, Fasciolidae). In Europe, spatial distribution of this parasite is evidently dynamic and ongoing process since new F. magna populations have constantly been emerging. Most recently, occurrence of F. magna in red deer (Cervus elaphus), sika deer (Cervus nippon), fallow deer (Dama dama), roe deer (Capreolus capreolus), and wild boar (Sus scrofa) was reported from north-eastern Bavaria in Germany. Fascioloides magna specimens collected from those hosts were genotyped using two mitochondrial regions; cytochrome c oxidase (cox1) and nicotinamide dehydrogenase (nad1). Results were compared with reference mitochondrial haplotypes of previously characterized European F. magna populations from northern Italy, Czech Republic/Poland, and the Danube floodplain forests. The study revealed genetic uniformity of F. magna specimens from Germany with flukes from the Czech focus, what indicated that fascioloidosis has been spreading beyond well established Czech focus into neighbouring countries.

Abstract
The veterinary important parasite of ruminants, giant liver fluke Fascioloides magna(Trematoda: Fasciolidae), isolated from liver of farmed fallow deer (Dama dama) from Podkarpackie Province (southeastern Poland) was genotypized by mitochondrial cytochrome c oxidase (cox1) and nicotinamide dehydrogenase (nad1) markers. The data on this newly emerged population were compared with mitochondrial haplotypes of recently detected Polish population of F. magna from Lower Silesian Wilderness (southwestern Poland) and with European populations of the parasite from all three natural foci; northern Italy, Czech Republic and the Danube floodplain forests. The flukes from Podkarpackie Province were found to be genetically identical with flukes from Czech Republic and Lower Silesian Wilderness in Poland. It is evident that central and southwestern Czech Republic, recognized as one of the endemic area of F. magna in Europe, has been enlarging and parasite has been invading several novel localities in Poland.

Abstract
The 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, EMBL and DDBJ databases under the accession numbers KP635008-9.

Abstract
Parasitic liver flukes of the family Fasciolidae are responsible for major socioeconomic losses worldwide. However, at present, knowledge of the fundamental molecular biology of these organisms is scant. Here, we characterize, for the first time, the transcriptome and secreted proteome of the adult stage of the "giant liver fluke," Fascioloides magna, using Illumina sequencing technology and one-dimensional SDS-PAGE and OFFGEL protein electrophoresis, respectively. A total of ∼54,000,000 reads were generated and assembled into ∼39,000 contiguous sequences (contigs); ∼20,000 peptides were predicted and classified based on homology searches, protein motifs, gene ontology, and biological pathway mapping. From the predicted proteome, 48.1% of proteins could be assigned to 384 biological pathway terms, including "spliceosome," "RNA transport," and "endocytosis." Putative proteins involved in amino acid degradation were most abundant. Of the 835 secreted proteins predicted from the transcriptome of F. magna, 80 were identified in the excretory/secretory products from this parasite. Highly represented were antioxidant proteins, followed by peptidases (particularly cathepsins) and proteins involved in carbohydrate metabolism. The integration of transcriptomic and proteomic datasets generated herein sets the scene for future studies aimed at exploring the potential role(s) that molecules might play at the host-parasite interface and for establishing novel strategies for the treatment or control of parasitic fluke infections.

Abstract
Fasciolid flukes are among the largest and best known digenetic trematodes and have considerable historical and veterinary significance. Fasciola hepatica is commonly implicated in causing disease in humans. The origins, patterns of diversification, and biogeography of fasciolids are all poorly known. We have undertaken a molecular phylogenetic study using 28S, internal transcribed spacer 1 and 2 (ITS-1 and ITS-2) of nuclear ribosomal DNA, and mitochondrial nicotinamide dehydrogenase subunit 1 (nad1) that included seven of the nine recognized species in the family. The fasciolids examined comprise a monophyletic group with the most basal species recovered from African elephants. We hypothesize fasciolids migrated from Africa to Eurasia, with secondary colonization of Africa. Fasciolids have been conservative in maintaining relatively large adult body size, but anatomical features of their digestive and reproductive systems are available. These flukes have been opportunistic, with respect to switching to new snail (planorbid to lymnaeid) and mammalian hosts and from intestinal to hepatic habitats within mammals.

Abstract
Fasciolopsis buski, the zoonotic intestinal flukes of pigs in South and Southeast Asia, is commonly prevalent in regions across Northeast India. Populations of the fluke collected from different parts of the region exhibit variations in morphology. The main objective of our study was to provide molecular characterization of the parasite so as to supplement morphological criteria, using ribosomal DNA cluster (rDNA), which is flanked by more conserved internal transcribed spacer (ITS) regions. We describe herein the ITS sequences of the parasite collected from swine hosts of Assam region. The ITS sequences of both egg and adult origins were found to be identical in length and composition. Phylogenetically, F. buski resembles closely the other members of family Fasciolidae, showing significant expectation value in the alignment. The results corroborate that the ITS sequences are not stage specific and are conserved through different stages of development of the fluke, and thus could be used as species markers.

Abstract
The nucleotide sequence of the 3' end of the second internal transcribed spacer region (ITS2) was determined for four isolates of Fasciola hepatica, two isolates of Fasciola gigantica, one isolate of Fascioloides magna and one isolate of Fasciola sp. from Japan. Intraspecific sequence divergence was negligible. Sequence divergence between F. hepatica and F. gigantica was 2.8% and between Fasciola hepatica and Fascioloides magna was 13.2%. The sequence of Fasciola sp. from Japan matched closely that of F. gigantica. This study demonstrates variability in nucleotide sequence within the ITS2 region which allows discrimination between species of Fasciolidae.
