As the intermediate host, sheep are highly susceptible to this disease. Our previous studies have shown that sheep with haplotype MHC Mva Ibc-Sac IIab-Hin1I ab were resistant to CE infection, while their counterparts without this haplotype were not. In order to reveal the molecular mechanism of resistance in Kazakh sheep, after selecting the differential miRNA in our previous study, herein, transcriptome analyses were conducted to detect the differential expression genes in the intestinal tissue of Kazakh sheep with resistant and non-resistant MHC haplotypes, after peroral infection with E. granulosus eggs. A total of 3835 differentially expressed genes were identified between the two groups, with 2229 upregulated and 1606 downregulated. Further function analysis showed that the most significant genes were related to both innate immune response and adaptive response participating in the defense against E. -

Diphyllobothriosis caused by adults of the genera Dibothriocephalus, Adenocephalus and Diphyllobothrium is usually not a life-threatening disease. Sparganosis, in contrast, is caused by larvae (plerocercoids) of species of Spirometra and can have serious health consequences, exceptionally leading to host's death in the case of generalised sparganosis caused by ‘Sparganum proliferum’. While most of the definitive wildlife hosts of broad tapeworms are recruited from marine and terrestrial mammal taxa (mainly carnivores and cetaceans), only a few diphyllobothriideans mature in fish-eating birds. In this review, we provide an overview the recent progress in our understanding of the diversity, phylogenetic relationships and distribution of broad tapeworms achieved over the last decade and outline the prospects of future research. The multigene family-wide phylogeny of the order published in 2017 allowed to propose an updated classi- fication of the group, including new generic assignment of the most important causative agents of human diphyllobothriosis, i.e., Dibothriocephalus latus and D. -
Spirometra Decipiens (Cestoda: Diphyllobothriidae) Collected in a Heavily Infected Stray Cat from the Republic of Korea

Eom* Department of Parasitology, Medical Research Institute and Parasite Resource Bank, Chungbuk National University School of Medicine, Cheongju 28644, Korea Abstract: Morphological and molecular characteristics of spirometrid tapeworms, Spirometra decipiens, were studied, which were recovered from a heavily infected stray cat road-killed in Eumseong-gun, Chungcheongbuk-do (Province), the Republic of Korea (= Korea). A total of 134 scolices and many broken immature and mature proglottids of Spirometra tapeworms were collected from the small intestine of the cat. Morphological observations were based on 116 specimens. The scolex was 22.8-32.6 mm (27.4 mm in average) in length and small spoon-shape with 2 distinct bothria. The uterus was coiled 3-4 times, the end of the uterus was ball-shaped, and the vaginal aperture shaped as a crescent moon was closer to the cirrus aperture than to the uterine aperture. PCR amplification and direct sequencing of the cox1 target frag- ment (377 bp in length and corresponding to positions 769-1,146 bp of the cox1 gene) were performed using total ge- nomic DNA extracted from 134 specimens. The cox1 sequences (377 bp) of the specimens showed 99.0% similarity to the reference sequence of S. decipiens and 89.3% similarity to the reference sequence of S. -

Rapid Identification of Nine Species of Diphyllobothriidean Tapeworms By
www.nature.com/scientificreports OPEN Rapid identification of nine species of diphyllobothriidean tapeworms by pyrosequencing Received: 20 July 2016 Tongjit Thanchomnang1,2, Chairat Tantrawatpan2,3, Pewpan M. Intapan2,4, Accepted: 26 October 2016 Oranuch Sanpool1,2,4, Viraphong Lulitanond2,5, Somjintana Tourtip1, Hiroshi Yamasaki6 & Published: 17 November 2016 Wanchai Maleewong2,4 The identification of diphyllobothriidean tapeworms (Cestoda: Diphyllobothriidea) that infect humans and intermediate/paratenic hosts is extremely difficult due to their morphological similarities, particularly in the case of Diphyllobothrium and Spirometra species. A pyrosequencing method for the molecular identification of pathogenic agents has recently been developed, but as of yet there have been no reports of pyrosequencing approaches that are able to discriminate among diphyllobothriidean species. This study, therefore, set out to establish a pyrosequencing method for differentiating among nine diphyllobothriidean species, Diphyllobothrium dendriticum, Diphyllobothrium ditremum, Diphyllobothrium latum, Diphyllobothrium nihonkaiense, Diphyllobothrium stemmacephalum, Diplogonoporus balaenopterae, Adenocephalus pacificus, Spirometra decipiens and Sparganum proliferum, based on the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene as a molecular marker. A region of 41 nucleotides in the cox1 gene served as a target, and variations in this region were used for identification using PCR plus pyrosequencing. This region contains nucleotide variations at 12 positions, which is enough for the identification of the selected nine species of diphyllobothriidean tapeworms. This method was found to be a reliable tool not only for species identification of diphyllobothriids, but also for epidemiological studies of cestodiasis caused by diphyllobothriidean tapeworms at public health units in endemic areas. The order Diphyllobothriidea (Platyhelminthes: Cestoda) is a large group of tapeworms that parasitize mammals, birds, amphibians and reptiles1,2. -

Eberhard,* Elizabeth A. Thiele, Gole E. Yembo, Makoy S. Yibi, Vitaliano A. Cama, and Ernesto Ruiz-Tiben Division of Parasitic Diseases and Malaria, Centers for Disease Control and Prevention, Atlanta, Georgia; Ethiopia Dracunculiasis Eradication Program, Federal Ministry of Health, Addis Ababa, Ethiopia; South Sudan Guinea Worm Eradication Program, Ministry of Health, Juba, Republic of South Sudan; The Carter Center, Atlanta, Georgia Abstract. Thirty-seven unusual specimens, three from Ethiopia and 34 from South Sudan, were submitted since 2012 for further identification by the Ethiopian Dracunculiasis Eradication Program (EDEP) and the South Sudan Guinea Worm Eradication Program (SSGWEP), respectively. Although the majority of specimens emerged from sores or breaks in the skin, there was concern that they did not represent bona fide cases of Dracunculus medinensis and that they needed detailed examination and identification as provided by the World Health Organization Collaborating Center (WHO CC) at Centers for Disease Control and Prevention (CDC). All 37 specimens were identified on microscopic study as larval tapeworms of the spargana type, and DNA sequence analysis of seven confirmed the identification of Spirometra sp. Age of cases ranged between 7 and 70 years (mean 25 years); 21 (57%) patients were male and 16 were female. The presence of spargana in open skin lesions is somewhat atypical, but does confirm the fact that populations living in these remote areas are either ingesting infected copepods in unsafe drinking water or, more likely, eating poorly cooked paratenic hosts harboring the parasite. -

Detection of Echinococcus Granulosus and Echinococcus Equinus in Dogs and Epidemiology of Canine Echinococcosis in the UK
Detection of Echinococcus granulosus and Echinococcus equinus in Dogs and Epidemiology of Canine Echinococcosis in the UK WAI SAN LETT A thesis submitted for the partial requirement of the degree of Doctor of Philosophy (Ph.D.) University of Salford School of Environment and Life Sciences 2013 Abstract Echinococcus granulosus is a canid cestode species that causes hydatid disease or cystic echinococcosis (CE) in domestic animals or humans. Echinococcus equinus formerly recognised as the ‘horse strain’ (E.granulosus genotype G4) is not known to be zoonotic and predominantly involves equines as its intermediate host. The domestic dog is the main definitive host for both species, which are also both endemic in the UK but data is lacking especially for E.equinus. An E.equinus-specific PCR assay was designed to amplify a 299bp product within the ND2 gene and expressed 100% specificity against a panel of 14 other cestode species and showed detection sensitivity up to 48.8pg (approx. 6 eggs). Horse hydatid cyst isolates (n = 54) were obtained from 14 infected horse livers collected from an abattoir in Nantwich, Cheshire and hydatid cyst tissue was amplified using the ND2 PCR primers to confirm the presence of E.equinus and used to experimentally infect dogs in Tunisia from which serial post-infection faecal samples were collected for coproanalysis, and indicated Echinococcus coproantigen and E.equinus DNA was present in faeces by 7 and 10 days post infection, respectively. Canine echinococcosis due to E.granulosus appears to have re-emerged in South Powys (Wales) and in order to determine the prevalence of canine echinococcosis a coproantigen survey was undertaken.
