Lisitsyna, O. I. Kudlai, O., Spraker, T. R., Kuzmina, T. A. — To increase the currently limited knowledge addressing acanthocephalans parasitizing California sea lions (Zalophus californianus), 33 animals including pups, juvenile and adult males and females from the Marine Mammal Center (TMMC), Sausalito, California, USA were examined. Totally, 2,268 specimens of acanthocephalans representing fi ve species from the genera Andracantha (A. phalacrocoracis and Andracantha sp.), Corynosoma (C. strumosum and C. obtuscens) and Profi licollis (P. altmani) were found. Profi licollis altmani and A. phalacrocoracis, predominantly parasitize fi sh-eating birds; they were registered in Z. californianus for the fi rst time. Prevalence and intensity of California sea lion infection and transmission of acanthocephalans in these hosts of diff erent age groups were analyzed and discussed. -

Inside their mammalian hosts, parasitic nematodes mainly dwell in the digestive tract (geohelminths) or in the vascular system (filariae). One of their main characteristics is their long sojourn inside the body where they are accessible to the immune system. Several strategies are used by parasites in order to counteract the immune attacks. One of them is the expression of molecules interfering with the function of the immune system. Excretory-secretory products (ESPs) pertain to this category. This is, however, not their only biological function, as they seem also involved in other mechanisms such as pathogenicity or parasitic cycle (molting, for example). Wewill mainly focus on filariae ESPs with an emphasis on data available regarding Onchocerca volvulus, but we will also refer to a few relevant/illustrative examples related to other worm categories when necessary (geohelminth nematodes, trematodes or cestodes). -

Two New Species of Cephalobidae from Valle De La Luna, Argentina, and Observations on the Genera Acrobeles and Nothacrobeles (Nematoda: Rhabditida)
Fundarn. appl. NernalOl., 1997,20 (4), 329-347 Two new species of Cephalobidae from Valle de la Luna, Argentina, and observations on the genera Acrobeles and Nothacrobeles (Nematoda: Rhabditida) Fayyaz SHAHINA* and Paul DE LEY* International Institute ofParasitology, 395a Hatfield Raad, St Albans, Herts AL4 OXU, England. Accepted for publication 5 August 1996. SUD1D1ary - Acrobeles emmatus sp. n. and Nochacrobeles lunensis sp. n. are described from a desert valley in Argentina. A. ernmatus sp. n. is distinct from ail known species of the genus in having an "inner layer" of the cuticle undulating twice per annule. N. lunensis sp. n. is distinct from ail other species of the genus in having a "double cuticle" as in Seleborca and Triligulla. We argue mat this type of cuticular structure must have arisen independently in at least three separate lineages, and mat it is insufficient as a genus character. Seleborca is therefore synonymized with Acrobeles, and Triligulla with Cervidellus. A single male of Nochacrobeles cf. subtilis is also described. Ir has minute tines on the probolae and a lateral field changing from four lines anteriorly to three lines posteriorly. We consider this to invalidate the genus Namibinema, which is merefore synonymized with Nochacrobeles. Tables of specifie differential characters are given to the re-defined genera Acrobeles and Nochacrobeles.

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. -
Parasitic Nematodes of Pool Frog (Pelophylax Lessonae) in the Volga Basin
Journal MVZ Cordoba 2019; 24(3):7314-7321. https://doi.org/10.21897/rmvz.1501 Research article Parasitic nematodes of Pool Frog (Pelophylax lessonae) in the Volga Basin Igor V. Chikhlyaev1 ; Alexander B. Ruchin2* ; Alexander I. Fayzulin1 1Institute of Ecology of the Volga River Basin, Russian Academy of Sciences, Togliatti, Russia 2Mordovia State Nature Reserve and National Park «Smolny», Saransk, Russia. *Correspondence: [email protected] Received: Febrary 2019; Accepted: July 2019; Published: August 2019. ABSTRACT Objetive. Present a modern review of the nematodes fauna of the pool frog Pelophylax lessonae (Camerano, 1882) from Volga basin populations on the basis of our own research and literature sources analysis. Materials and methods. Present work consolidates data from different helminthological works over the past 80 years, supported by our own research results. During the period from 1936 to 2016 different authors examined 1460 specimens of pool frog, using the method of full helminthological autopsy, from 13 regions of the Volga basin. Results. In total 9 nematodes species were recorded. Nematode Icosiella neglecta found for the first time in the studied host from the territory of Russia and Volga basin. Three species appeared to be more widespread: Oswaldocruzia filiformis, Cosmocerca ornata and Icosiella neglecta. For each helminth species the following information included: systematic position, areas of detection, localization, biology, list of definitive hosts, the level of host-specificity. Conclusions. Nematodes of pool frog, excluding I. neglecta, belong to the group of soil-transmitted helminthes (geohelminth) and parasitize in adult stages. Some species (O. filiformis, C. ornata, I. neglecta) are widespread in the host range. -

Most cephalobs are also characterized by the presence of six lips and three labial probolae around the oral opening, both structures becoming highly variable and especially useful for separation of genera. -
Phylogenetic and Population Genetic Studies on Some Insect and Plant Associated Nematodes
PHYLOGENETIC AND POPULATION GENETIC STUDIES ON SOME INSECT AND PLANT ASSOCIATED NEMATODES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Amr T. M. Saeb, M.S. * * * * * The Ohio State University 2006 Dissertation Committee: Professor Parwinder S. Grewal, Adviser Professor Sally A. Miller Professor Sophien Kamoun Professor Michael A. Ellis Approved by Adviser Plant Pathology Graduate Program Abstract: Throughout the evolutionary time, nine families of nematodes have been found to have close associations with insects. These nematodes either have a passive relationship with their insect hosts and use it as a vector to reach their primary hosts or they attack and invade their insect partners then kill, sterilize or alter their development. In this work I used the internal transcribed spacer 1 of ribosomal DNA (ITS1-rDNA) and the mitochondrial genes cytochrome oxidase subunit I (cox1) and NADH dehydrogenase subunit 4 (nd4) genes to investigate genetic diversity and phylogeny of six species of the entomopathogenic nematode Heterorhabditis. Generally, cox1 sequences showed higher levels of genetic variation, larger number of phylogenetically informative characters, more variable sites and more reliable parsimony trees compared to ITS1-rDNA and nd4. The ITS1-rDNA phylogenetic trees suggested the division of the unknown isolates into two major phylogenetic groups: the HP88 group and the Oswego group. All cox1 based phylogenetic trees agreed for the division of unknown isolates into three phylogenetic groups: KMD10 and GPS5 and the HP88 group containing the remaining 11 isolates. KMD10, GPS5 represent potentially new taxa. The cox1 analysis also suggested that HP88 is divided into two subgroups: the GPS11 group and the Oswego subgroup. -
