The Morphological and Molecular Characterization of Baylisascaris
Sharifdini et al. Parasites Vectors (2021) 14:33 https://doi.org/10.1186/s13071-020-04513-4 Parasites & Vectors RESEARCH Open Access The morphological and molecular characterization of Baylisascaris devosi Sprent, 1952 (Ascaridoidea, Nematoda), collected from Pine marten (Martes martes) in Iran Meysam Sharifdini1*, Richard A. Heckmann2 and Fattaneh Mikaeili3 Abstract Background: Baylisascaris devosi is an intestinal nematode found in several carnivores including fsher, wolverine, Beech marten, American marten and sable in diferent parts of the world, but this nematode has not been reported from Pine marten. Therefore, this study aimed to identify Baylisascaris isolated from a Pine marten in Iran using mor- phological and molecular approaches. Methods: Specimens of B. devosi were collected from one road-killed Pine marten in northern Iran. Morphological features were evaluated using scanning electron microscopy, energy dispersive x-ray analysis and ion sectioning. The molecular characterization was carried out using partial Cox1, LSU rDNA and ITS-rDNA genes. Results: The nematodes isolated from the Pine marten were confrmed to be B. devosi based on the morphological features and the sequence of ribosomal and mitochondrial loci. X-ray scans (EDAX) were completed on gallium cut structures (papillae, eggs, male spike and mouth denticles) of B. devosi using a dual-beam scanning electron micro- scope. The male spike and mouth denticles had a high level of hardening elements (Ca, P, S), helping to explain the chemical nature and morphology of the worm. Based on these genetic marker analyses, our sequence had the great- est similarity with Russian B. devosi isolated from sable. Conclusions: In this study, to our knowledge, the occurrence of B. -
Acanthocephala: Rhadinorhynchidae) from the Red Porgy Pagrus Pagrus (Teleostei: Sparidae) of the Red Sea, Egypt: a Morphological Study
Acta Parasitologica Globalis 9 (3): 133-140 2018 ISSN 2079-2018 © IDOSI Publications, 2018 DOI: 10.5829/idosi.apg.2018.133.140 Serrasentis Sagittifer Linton, 1889 (Acanthocephala: Rhadinorhynchidae) from the Red Porgy Pagrus pagrus (Teleostei: Sparidae) of the Red Sea, Egypt: A Morphological Study 11Nahed Saed, Mahrashan Abdel-Gawad, 2Sahar El-Ganainy, 21Manal Ahmed, Kareem Morsy and 3Asmaa Adel 1Zoology Department, Faculty of Science, Cairo University, Cairo, Egypt 2Zoology Department, Faculty of Science, Minia University, Minya, Egypt 3Zoology Department, Faculty of Science, South Valley University, Qena, Egypt Abstract: In the present study, an acanthocephalan parasite was recovered from the intestine of the red porgy Pagrus pagrus (Sparidae) captured from water locations along the Red Sea at Hurghada coasts, Egypt. The parasite was observed attached to the wall of the host intestine by an armed proboscis equipped by recurved hooks. 14 out of 40 fish specimens (35.0%) were found to be infected during winter season only. The mean intensity ranged from 4-10 parasites/infected fish. The recovered worms were creamy white, elongated with narrow posterior end. Light and scanning electron microscopy showed that the parasite has distinctive rows of spines (combs) on the ventral surface. Body was 3.55±0.02 (3.33-3.58) mm long. Width at the base of probocis was 0.10±0.02 (0.08-0.12) mm. Proboscis club-shaped with a broad anterior end, euipped by longitudinal rows of hooks, each with 15-19 of curved hooks. Neck smooth, the double-walled receptacle was attached to the proboscis wall. Trunk was spinose anteriorly, spines arranged in 7-10 collar rows, each was equipped with 15-18 spines. -

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. -

E-mail: [email protected], Tel.: +49 (0) 89 2180 6635; Fax: +49 (0) 89 2180 6601 Abstract The diversity and phylogenetic relationships of calcareous sponges are still not completely understood. Recent integrative approaches combined analyses of DNA and morphological observations. Such studies resulted in severe taxonomic revi- sions within the subclass Calcinea and provided the foundation for a phylogenetically meaningful classification. However, several genera are missing from DNA phylogenies and their relationship to other Calcinea remain uncertain. One of these genera is Leuclathrina (family Leucaltidae). We here describe a new species from the Maldives, Leuclathrina translucida sp. nov., which is only the second species of the genus. Like the type species Leuclathrina asconoides, the new species has a leuconoid aquiferous system and lacks a specialized choanoskeleton. -

Nickol 9.1 Introduction In practice, epizootiology deals with how parasites spread through host populations, how rapidly the spread occurs and whether or not epizootics result. Prevalence, incidence, factors that permit establishment ofinfection, host response to infection, parasite fecundity and methods of transfer are, therefore, aspects of epizootiology. Indeed, most aspects of a parasite could be related in sorne way to epizootiology, but many ofthese topics are best considered in other contexts. General patterns of transmission, adaptations that facilitate transmission, establishment of infection and occurrence of epizootics are discussed in this chapter. When life cycles are unknown, little progress can be made in under standing the epizootiological aspects ofany group ofparasites. -
