Serum samples from mice were taken at three, 12 and 24 hours post infection and at four day intervals thereafter for a period of 12 weeks. Sera from these groups analyzed by electrophoresis exhibited decreased serum albumin concentrations and generally increases in the alpha, beta and gamma globulins. Rabbits passively immunized against the plerocercoids of these species exhibited little change in the total proteins after immuniza­ tion. Changes in the protein fractions were expressed as slight decreases in albumin and a corresponding increase in the gamma globulins. Precipitin bands were demonstrable by double gel diffusion in sera from all groups of mice infected with the plerocercoids of the three species of worms. Sera from rabbits passively immunized against the three species formed a maximum of three precipitin bands in agar gel six weeks post immunization. Intradermal tests in mice passively immunized against Spirometra mansoni and S. urichi gave widely variable results. Reactions obtained with injection of larval antigens indicate the presence of delayed hypersensitivity. viii INTRODUCTION Faust, et al. (1929) divided the genus Diphyllobothrium Cobbold, 1858, into two subgenera, Diphyllobothrium and Spirometra, based on uterine configuration and the shape of the eggs. Diphyllobothrium was to include those species with the outer uterine coils forming a. rosette and eggs with rounded ends. The subgenus Spirometra was to include those species with the outer uterine coils spiralled and eggs with pointed ends. Mueller (1937) elevated Spirometra to generic rank and further suggested the establishment of two other genera, subsequently named Dibothriocephalus and Cordicephalus by Wardle, et al. (1947). The cirrus, vagina and uterus open separately in Spirometra, whereas, the other two genera have common cirro-vaginal atria and separate pores. As further evidence for separation, Mueller (1937) noted

  • Conservation and Diversification of Small RNA Pathways Within Flatworms Santiago Fontenla1, Gabriel Rinaldi2, Pablo Smircich1,3 and Jose F
    Fontenla et al. BMC Evolutionary Biology (2017) 17:215 DOI 10.1186/s12862-017-1061-5 RESEARCH ARTICLE Open Access Conservation and diversification of small RNA pathways within flatworms Santiago Fontenla1, Gabriel Rinaldi2, Pablo Smircich1,3 and Jose F. Tort1* Abstract Background: Small non-coding RNAs, including miRNAs, and gene silencing mediated by RNA interference have been described in free-living and parasitic lineages of flatworms, but only few key factors of the small RNA pathways have been exhaustively investigated in a limited number of species. The availability of flatworm draft genomes and predicted proteomes allowed us to perform an extended survey of the genes involved in small non-coding RNA pathways in this phylum. Results: Overall, findings show that the small non-coding RNA pathways are conserved in all the analyzed flatworm linages; however notable peculiarities were identified. While Piwi genes are amplified in free-living worms they are completely absent in all parasitic species. Remarkably all flatworms share a specific Argonaute family (FL-Ago) that has been independently amplified in different lineages. Other key factors such as Dicer are also duplicated, with Dicer-2 showing structural differences between trematodes, cestodes and free-living flatworms. Similarly, a very divergent GW182 Argonaute interacting protein was identified in all flatworm linages. Contrasting to this, genes involved in the amplification of the RNAi interfering signal were detected only in the ancestral free living species Macrostomum lignano. We here described all the putative small RNA pathways present in both free living and parasitic flatworm lineages. Conclusion: These findings highlight innovations specifically evolved in platyhelminths presumably associated with novel mechanisms of gene expression regulation mediated by small RNA pathways that differ to what has been classically described in model organisms.

  • Broad Tapeworms (Diphyllobothriidae)
    IJP: Parasites and Wildlife 9 (2019) 359–369 Contents lists available at ScienceDirect IJP: Parasites and Wildlife journal homepage: www.elsevier.com/locate/ijppaw Broad tapeworms (Diphyllobothriidae), parasites of wildlife and humans: T Recent progress and future challenges ∗ Tomáš Scholza, ,1, Roman Kuchtaa,1, Jan Brabeca,b a Institute of Parasitology, Biology Centre of the Czech Academy of Sciences, Branišovská 31, 370 05, České Budějovice, Czech Republic b Natural History Museum of Geneva, PO Box 6434, CH-1211, Geneva 6, Switzerland ABSTRACT Tapeworms of the family Diphyllobothriidae, commonly known as broad tapeworms, are predominantly large-bodied parasites of wildlife capable of infecting humans as their natural or accidental host. 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.

  • Hymenolepis Nana Is a Ubiquitous Parasite, Found Throughout Many Developing and Developed Countries
    Characterisation of Community-Derived Hymenolepis Infections in Australia Marion G. Macnish BSc. (Medical Science) Hons Division of Veterinary and Biomedical Sciences Murdoch University Western Australia This thesis is presented for the degree of Doctor of Philosophy of Murdoch University 2001 I declare that this thesis is my own account of my research and contains as its main work which has not been submitted for a degree at any other educational institution. ………………………………………………. (Marion G. Macnish) Characterisation of Community-Derived Hymenolepis Infections in Australia ii Abstract Hymenolepis nana is a ubiquitous parasite, found throughout many developing and developed countries. Globally, the prevalence of H. nana is alarmingly high, with estimates of up to 75 million people infected. In Australia, the rates of infection have increased substantially in the last decade, from less than 20% in the early 1990’s to 55 - 60% in these same communities today. Our knowledge of the epidemiology of infection of H. nana is hampered by the confusion surrounding the host specificity and taxonomy of this parasite. The suggestion of the existence of two separate species, Hymenolepis nana von Siebold 1852 and Hymenolepis fraterna Stiles 1906, was first proposed at the beginning of the 20th century. Despite ongoing discussions in the subsequent years it remained unclear, some 90 years later, whether there were two distinct species, that are highly host specific, or whether they were simply the same species present in both rodent and human hosts. The ongoing controversy surrounding the taxonomy of H. nana has not yet been resolved and remains a point of difference between the taxonomic and medical literature.

  • Waterborne Zoonotic Helminthiases Suwannee Nithiuthaia,*, Malinee T
    Veterinary Parasitology 126 (2004) 167–193 www.elsevier.com/locate/vetpar Review Waterborne zoonotic helminthiases Suwannee Nithiuthaia,*, Malinee T. Anantaphrutib, Jitra Waikagulb, Alvin Gajadharc aDepartment of Pathology, Faculty of Veterinary Science, Chulalongkorn University, Henri Dunant Road, Patumwan, Bangkok 10330, Thailand bDepartment of Helminthology, Faculty of Tropical Medicine, Mahidol University, Ratchawithi Road, Bangkok 10400, Thailand cCentre for Animal Parasitology, Canadian Food Inspection Agency, Saskatoon Laboratory, Saskatoon, Sask., Canada S7N 2R3 Abstract This review deals with waterborne zoonotic helminths, many of which are opportunistic parasites spreading directly from animals to man or man to animals through water that is either ingested or that contains forms capable of skin penetration. Disease severity ranges from being rapidly fatal to low- grade chronic infections that may be asymptomatic for many years. The most significant zoonotic waterborne helminthic diseases are either snail-mediated, copepod-mediated or transmitted by faecal-contaminated water. Snail-mediated helminthiases described here are caused by digenetic trematodes that undergo complex life cycles involving various species of aquatic snails. These diseases include schistosomiasis, cercarial dermatitis, fascioliasis and fasciolopsiasis. The primary copepod-mediated helminthiases are sparganosis, gnathostomiasis and dracunculiasis, and the major faecal-contaminated water helminthiases are cysticercosis, hydatid disease and larva migrans. Generally, only parasites whose infective stages can be transmitted directly by water are discussed in this article. Although many do not require a water environment in which to complete their life cycle, their infective stages can certainly be distributed and acquired directly through water. Transmission via the external environment is necessary for many helminth parasites, with water and faecal contamination being important considerations.

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.

    BLOOD COAGULATION AND HAEMOSTASIS: A REVIEW* E. M. RODF_~QUE,M.D. AND J. E. WYNANDS, M.D., C.IVI.~ FnOM THE V~Y F_~aLY STUVmS of this subject, many controversies existed regard- ing the various factors and mechanisms involved in the dotting process. One simply has to review the current literature and note the complex, often variable terminology, and the differing opinions of several workers in this field to realize that many of the former controversies are still present. However, many facts have been firmly established. This review will deal primarily with these facts and will mention the disputed points only when they appear pertinent to a better under- standing of the problems of controlling haemorrhage. Various factors are involved in the haemostatic process; the established ones include (1) the extravascular tissues; (2) the vasculature itself, the size and type of vessel being important; (3) the number of functioning platelets, and (4) the plasma coagulation system,x,2 THE ErmAVASCtrLABTISSUES While the extravaseular tissues do not play a major role in the control of bleeding, yet "their integrity and/or the variations in the resistance they offer to escaping blood may determine the bleeding response of a particular part of the body after injury. The "black eye' is a well-known example."2 In other situations in which there is easy bruisability, as in the aged, in poor nutrition, in some women, and in disease states such as the Ehlers-Danlos syndrome, it is likely that poor extravascular support is a deciding or contributing factor. 2 THE V~CULATVBE Previous to the more advanced and tested knowledge of today, abnormal vascular function was implicated as the basic pathogenetic factor in a variety of bleeding disorders.

Estes foram necropsiados, filetados e seus órgãos analisados. Dos 74 espécimes analisados, 18 (24,3%) estavam parasitados por plerocercóides pertencentes ao gênero Diphyllobothrium Cobbold, 1858 na cavidade abdominal, serosa do intestino, intestino e musculatura, onde a intensidade média de infecção foi de 1,66 parasitos por peixe, a amplitude de variação da intensidade de infecção variou de um a sete e a abundância média foi de 0,40. Este é o primeiro registro de plerocercóides de Diphyllobothrium sp. em peixes teleósteos no Brasil. Palavras-chave: Diphyllobothrium sp., Genypterus brasiliensis, Brasil. Abstract Between October 2002 and September 2003 were collected 74 specimens of Genypterus brasiliensis purchased in the Niterói and Rio de Janeiro municipalities. Those were necropsied, fileted and their organs analyzed. From 74 specimens analyzed, 18 (24,3%) were parasitized by plerocercoids of Diphyllobothrium Cobbold, 1858 on the cavity abdominal, intestine serose, intestine and musculature, where the mean intensity of infection was 1,66 parasites per fish, the range was one to seven and mean abundance was 0,40.
