Love S Taeniid Tapeworms Incl T Ovis
Taeniid tapeworms incl T.ovis (‘sheep ‘measles’) – some notes SL, DPI Armidale May 2016 Following is my interpretive summary of various, especially Jenkins et al, 2014 (J1).These are somewhat disorganised notes, not a polished treatise! Information mostly from JI unless stated otherwise. J1 : “Data collected through the Australian National Sheep Health Monitoring Program (NSHMP) (AHA, 2011 ) reported metacestodes of T. ovis to be widespread and common in sheep slaughtered in mainland Australia 1, but less common in Tasmania. Sheep infected with metacestodes of T. hydatigena are also found commonly in slaughtered sheep from all sheep rearing areas of mainland Australia but less commonly in Tasmania (Animal Health Australia, unpublished data)” ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [SL:] Prevalence of sheep measles and of adult T ovis in AU. In 2014-2015, ~ 15000 lines of sheep (incl. lambs) which amounted to ~ 3 million sheep incl. lambs were inspected as part of NSHMP. This was in 18 abattoirs, across various states. Approx two thirds of the lines were direct lines (direct consignments to the abattoir). However, two of the biggest mutton processors in NSW (Dubbo, Goulburn) are not part of NSHMP. In 2015, approx. 31 million sheep were slaughtered in AU (~ 8.5M sheep, 22.2 M lambs). Total AU sheep pop is ~ 70M (Source: MLA). So, the sheep inspected under NSHMP is about 10% of all those slaughtered and two major mutton processors are not involved. Question then: how representative are the NSHMP results of the AU sheep population? Indicative only? J1, citing NSHMP data, say sheep measles (metacestodes of T ovis) are widespread and common in sheep slaughtered in AU, especially in mainland AU. -

The examined nematodes are predominantly parasites of fishes. Their analyses provided well-supported trees allowing the study of phylogenetic relationships among some spirurine nematodes. The present results support the placement of Cucullanidae at the base of the suborder Spirurina and, based on the position of the genus Philonema (subfamily Philoneminae) forming a sister group to Skrjabillanidae (thus Philoneminae should be elevated to Philonemidae), the paraphyly of the Philometridae. Comparison of a large number of sequences of representatives of the latter family supports the paraphyly of the genera Philometra, Philometroides and Dentiphilometra. The validity of the newly included genera Afrophilometra and Carangi- nema is not supported. These results indicate geographical isolation has not been the cause of speciation in this parasite group and no coevolution with fish hosts is apparent. On the contrary, the group of South-American species ofAlinema , Nilonema and Rumai is placed in an independent branch, thus markedly separated from other family members. -

Ahmed and Shimaa, Abd-El-Moaty Department of Zoology, Faculty of Science, Zagazig University, Egypt [email protected] Abstract: The present study compares ultrastructure of the spermatozoa of Cotugnia polycantha recovered from the intestine of the two different host, Columba livia domestica and Streptopelia senegalensis from Egypt. The spermatozoa of C. polycantha of the two different host are filiform, tapered at the anterior extremity and lack mitochondria. The anterior extremity has an apical cone of electron dense material and two helicoidal thick cord crested-like body. The axoneme possesses the 9+"1" pattern of microtubules and contains the peri-axonemal sheath. The cortical microtubules are spiraled along the whole length of the spermatozoon. The spermatozoon of C. polycantha of C. livia consists of five regions (I-V), while the other consists of four regions (I-IV). The cytoplasm contains numerous and large electron dense granules only in the region V in case of C. polycantha of C. livia but, these granules are also found in the regions I, II and IV in the spermatozoon of C. polycantha of S. senegalensis. The nucleus is a fine compact cord and envelops the central axoneme once or twice, interposes itself between the cortical microtubules in case of C. polycantha of C. livia which is different in that of C. polycantha of S. senegalensis in which the nucleus is coiled in a helix around the axoneme. -

(Gmelin, 1790) in the Critically Endangered European Mink Mustela Lutreola (Linnaeus, 1761) in Spain
Parasitology Research https://doi.org/10.1007/s00436-018-6043-z SHORT COMMUNICATION Severe parasitism by Versteria mustelae (Gmelin, 1790) in the critically endangered European mink Mustela lutreola (Linnaeus, 1761) in Spain Christine Fournier-Chambrillon1 & Jordi Torres2,3 & Jordi Miquel2,3 & Adrien André4 & Johan Michaux4 & Karin Lemberger5 & Gloria Giralda Carrera6 & Pascal Fournier1 Received: 25 June 2018 /Accepted: 3 August 2018 # Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract The riparian European mink (Mustela lutreola), currently surviving in only three unconnected sites in Europe, is now listed as a critically endangered species in the IUCN Red List of Threatened Species. Habitat loss and degradation, anthropogenic mortality, interaction with the feral American mink (Neovison vison), and infectious diseases are among the main causes of its decline. In the Spanish Foral Community of Navarra, where the highest density of M. lutreola in its western population has been detected, different studies and conservation measures are ongoing, including health studies on European mink, and invasive American mink control. We report here a case of severe parasitism with progressive physiological exhaustion in an aged free-ranging European mink female, which was accidentally captured and subsequently died in a live-trap targeting American mink. Checking of the small intestine revealed the presence of 17 entangled Versteria mustelae worms. To our knowledge, this is the first description of hyperinfestation by tapeworms in -
Evaluation of Some Vulval Appendages in Nematode Taxonomy
Comp. Parasitol. 76(2), 2009, pp. 191–209 Evaluation of Some Vulval Appendages in Nematode Taxonomy 1,5 1 2 3 4 LYNN K. CARTA, ZAFAR A. HANDOO, ERIC P. HOBERG, ERIC F. ERBE, AND WILLIAM P. WERGIN 1 Nematology Laboratory, United States Department of Agriculture–Agricultural Research Service, Beltsville, Maryland 20705, U.S.A. (e-mail: [email protected], [email protected]) and 2 United States National Parasite Collection, and Animal Parasitic Diseases Laboratory, United States Department of Agriculture–Agricultural Research Service, Beltsville, Maryland 20705, U.S.A. (e-mail: [email protected]) ABSTRACT: A survey of the nature and phylogenetic distribution of nematode vulval appendages revealed 3 major classes based on composition, position, and orientation that included membranes, flaps, and epiptygmata. Minor classes included cuticular inflations, protruding vulvar appendages of extruded gonadal tissues, vulval ridges, and peri-vulval pits. Vulval membranes were found in Mermithida, Triplonchida, Chromadorida, Rhabditidae, Panagrolaimidae, Tylenchida, and Trichostrongylidae. Vulval flaps were found in Desmodoroidea, Mermithida, Oxyuroidea, Tylenchida, Rhabditida, and Trichostrongyloidea. Epiptygmata were present within Aphelenchida, Tylenchida, Rhabditida, including the diverged Steinernematidae, and Enoplida. Within the Rhabditida, vulval ridges occurred in Cervidellus, peri-vulval pits in Strongyloides, cuticular inflations in Trichostrongylidae, and vulval cuticular sacs in Myolaimus and Deleyia. Vulval membranes have been confused with persistent copulatory sacs deposited by males, and some putative appendages may be artifactual. Vulval appendages occurred almost exclusively in commensal or parasitic nematode taxa. Appendages were discussed based on their relative taxonomic reliability, ecological associations, and distribution in the context of recent 18S ribosomal DNA molecular phylogenetic trees for the nematodes. -

4. Discussion
4. Discussion Chez les digènes objets de notre étude (Scaphiostomum palaearcticum, Notocotylus neyrai, Fasciola gigantica et F. hepatica) la spermiogenèse suit le modèle général décrit chez tous les trématodes déjà étudiés (Burton, 1972 ; Rees, 1979 ; Erwin & Halton, 1983 ; Hendow & James, 1988 ; Cifrián et al., 1993 ; Miquel et al., 2000a). Elle commence par la formation d’une zone de différentiation à la base de la spermatide. Cette zone présente deux centrioles séparés par un corps intercentriolaire et surmonté chacun par une racine striée. Chaque centriole donne naissance à un flagelle généralement disposé perpendiculairement à l’expansion cytoplasmique médiane. Ensuite, les deux flagelles subissent une rotation pour devenir parallèles à l’expansion cytoplasmique médiane, puis fusionnent avec cette dernière, marquant ainsi la fin de la spermiogenèse. Ce processus de fusion, nommé fusion proximo- distale (« proximodistal fusion ») a été décrite pour la première fois par Justine (1991a). Absente chez les Turbellariés, elle est l’événement majeur de la spermiogenèse des Plathelminthes parasites ou Cercomeridea. Elle a pour principale conséquence la présence de microtubules dorsaux et ventraux dans la région principale (région nucléaire) du spermatozoïde. Considérée comme une synapomorphie caractéristique des Cercomeridea, mais pas des Neodermata (= Udonellidea + Cercomeridea) par Justine (1991a), elle a donc un grand intérêt phylogénétique. La fusion proximo-distale, ainsi que la rotation flagellaire (« flagellar rotation ») qui la précéde ont été décrites comme un processus asynchrone chez divers digènes dont un Dicrocoelidae, Dicrocoelium dendriticum (Cifrián et al., 1993), un Lecithodendriidae, Postorchigenes gymnesicus (Gracenea et al., 1997), un Opecoelidae, Opecoeloides furcatus (Miquel et al., 2000a), un Haploporidae, Saccocoelioides godoyi (Baptista-Farias et al., 2001), un Brachylaimidae, Scaphiostomum palaearcticum (Ndiaye et al., 2002), un Notocotylidae, Notocotylus neyrai (Ndiaye et al., 2003d) et deux Fasciolidae Fasciola gigantica et F.
