They are soft bodied, unsegmented, dorsoventrally flattened worms having a bilateral symmetry, with organ grade of organization. Flatworms are acoelomate and triploblastic. The majority of these are parasitic. The free living forms are generally aquatic, either marine or fresh water. Digestive system is either absent or incomplete with a single opening- the mouth, anus is absent. Circulatory, respiratory and skeletal system are absent. Excretion and osmoregulation is brought about by protonephridia or flame cells. Ammonia is the chief excretory waste product. Nervous system is of the primitive type having a pair of cerebral ganglia and longitudinal nerves connected by transverse commissures. Sense organs are poorly developed, present only in the free living forms. Basically hermaphrodite with a complex reproductive system. Development is either direct or indirect with one or more larval stages. Flatworms have a remarkable power of regeneration. The phylum includes about 13,000 species. Here Dugesia and Fasciola hepatica will be described as the type study to understand the phylum. Some of the medically important parasitic helminthes will also be discussed. Evolution of parasitism and parasitic adaptations is of utmost importance for the endoparasitic platyhelminthes and will also be discussed here. -

SCALE-DEPENDENT VARIATION IN MOLECULAR AND ECOLOGICAL PATTERNS OF INFECTION FOR ENDOHELMINTHS FROM CENTRARCHID FISHES BY KYLE E. LUTH A Dissertation Submitted to the Graduate Faculty of WAKE FOREST UNIVERSITY GRADAUTE SCHOOL OF ARTS AND SCIENCES in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Biology May 2016 Winston-Salem, North Carolina Approved By: Gerald W. Esch, Ph.D., Advisor Michael V. K. Sukhdeo, Ph.D., Chair T. Michael Anderson, Ph.D. Herman E. Eure, Ph.D. Erik C. Johnson, Ph.D. Clifford W. Zeyl, Ph.D. ACKNOWLEDGEMENTS First and foremost, I would like to thank my PI, Dr. Gerald Esch, for all of the insight, all of the discussions, all of the critiques (not criticisms) of my works, and for the rides to campus when the North Carolina weather decided to drop rain on my stubborn head. The numerous lively debates, exchanges of ideas, voicing of opinions (whether solicited or not), and unerring support, even in the face of my somewhat atypical balance of service work and dissertation work, will not soon be forgotten. I would also like to acknowledge and thank the former Master, and now Doctor, Michael Zimmermann; friend, lab mate, and collecting trip shotgun rider extraordinaire. Although his need of SPF 100 sunscreen often put our collecting trips over budget, I could not have asked for a more enjoyable, easy-going, and hard-working person to spend nearly 2 months and 25,000 miles of fishing filled days and raccoon, gnat, and entrail-filled nights. You are a welcome camping guest any time, especially if you do as good of a job attracting scorpions and ants to yourself (and away from me) as you did on our trips. -

Connior Life Sciences, Northwest Arkansas Community College, Bentonville, AR 72712 Abstract: Between May 2013 and September 2015, two amphibian and eight reptilian species/ subspecies were collected from Atoka (n = 1) and McCurtain (n = 31) counties, Oklahoma, and examined for helminth parasites. Twelve helminths, including a monogenean, six digeneans, a cestode, three nematodes and two acanthocephalans was found to be infecting these hosts. We document nine new host and three new distributional records for these helminths.

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. -

E-mail: [email protected] Abstract The present study contributes to the knowledge of the cestode fauna of species of Styracura de Carvalho, Loboda & da Silva, which is the putative sister taxon of freshwater potamotrygonids—a unique group of batoids restricted to Neotro- pical freshwater systems. We document species of Rhinebothrium Linton, 1890 as a result of the examination of newly collected specimens of Styracura from five different localities representing the eastern Pacific Ocean and the Caribbean Sea. Overall, we examined 33 spiral intestines, 11 from the eastern Pacific species Styracura pacifica (Beebe & Tee-Van) and 22 from the Caribbean species S. schmardae (Werner). However, only samples from the Caribbean were infected with members of Rhinebothrium. Rhinebothrium tetralobatum Brooks, 1977, originally described from S. schmardae—as Hi- mantura schmardae (Werner)—off the Caribbean coast of Colombia based on six specimens is redescribed. This rede- scription provides the first data on the microthriches pattern, more details of internal anatomy (i.e., inclusion of histological sections) and expands the ranges for the counts and measurements of several features. -
Reporting a New Caryophyllidean Worm from a Freshwater Clarias Batrachus
© 2020 JETIR October 2020, Volume 7, Issue 10 www.jetir.org (ISSN-2349-5162) REPORTING A NEW CARYOPHYLLIDEAN WORM FROM A FRESHWATER CLARIAS BATRACHUS 1Khushal Bhavsar, 2Avinash Bhangale and 3Ajit Kalse, 1Researcher, 2Associate Professor, & 3Professor Helminth Research Laboratory, P.G. Department of Zoology, Nanasaheb Y. N. Chavan ASC College, Chalisgaon Dist. Jalgaon-424101, (M.S.) Abstract: Present study deals with reporting of a Caryophyllidean tapeworm Lytocestus sahayi n. sp. collected from intestine of freshwater catfish Clarias batrachus (Linneus, 1758) from Mundkhede Dam near Chalisgaon (M.S.) India. Worm comes closer to all known species of the genus Lytocestus, in general topography of organs, but differs due to long head, tapering anteriorly, well-marked off from body. Testes oval to rounded, 500- 530 in number, unevenly distributed. Cirrus pouch large, oval, preovarian, vertically placed, cirrus thin, straight, vas deferens short, thin, coiled. Ootype is small, oval. Vagina long, thin tube, coiled. Ovary bilobed, ‘Butterfly’ shaped, with 25-28 ovarian follicles, situated in posterior region of the worm. Eggs are oval, operculated. Vitellaria are granular, arranged in two rows. Index Terms- Cestode, Clarias batrachus, Lytocestus, Mundkhede. INTRODUCTION Cohn, 1908 erected the genus Lytocestus with its type species L. adhaerens from edible cat fish Clarias fuscus at HongKong. This genus was first confirmed by Woodland, 1926 that included four more species in addition to the type species. They are L. filiformis Woodland, 1923 in Mormyrus caschive, Egyptian Sudan; L. chalmersius Woodland, 1924; L. cunningtoni Fuhrmann and Baer, 1925 and L. indicus Moghe, 1925 (Syn. Caryophyllaeces indicus) from Clarias batrachus in India. Later, Hunter, 1927 placed the genus in subfamily of its own, viz. -

The parasitic fauna included two myzozoans, one choanozoan, seven ciliophorans, 24 myxozoans, eight trematodes, 34 monogeneans, 12 cestodes, 11 nematodes, five acanthocephalans, two annelids and nine crustaceans. The infection with some trematodes and nematodes occurred with larval stages, while the remaining infections were either with trophozoites or adult parasites. Among the inspected fishes, Cyprinion macrostomum was infected with the highest number of parasite species (29 parasite species), followed by Carasobarbus luteus (26 species) and Arabibarbus grypus (22 species) while six fish species (Alburnus caeruleus, A. sellal, Barbus lacerta, Cyprinion kais, Hemigrammocapoeta elegans and Mastacembelus mastacembelus) were infected with only one parasite species each. The myxozoan Myxobolus oviformis was the commonest parasite species as it was reported from 10 fish species, followed by both the myxozoan M. pfeifferi and the trematode Ascocotyle coleostoma which were reported from eight fish host species each and then by both the cestode Schyzocotyle acheilognathi and the nematode Contracaecum sp. -

It was originally described from a small cyprinid, Acheilognathus rombeus, in Japan but then has spread, usually with carp, minnows or guppies, to all continents including isolated islands such as Hawaii, Puerto Rico, Cuba or Sri Lanka. In the present account, we report the fi rst case of the infection of a native cichlid fi sh, Ptychochromis cf. inornatus (Perciformes: Cichlidae), endemic to Madagascar, with S. acheilognathi. The way of introduction of this parasite to the island, which is one of the world’s biodiversity hotspots, is briefl y discussed.
