Con ello damos un anticipo de lo que será nuestra próxima obra, en la cual, además de actualizar los problemas taxonómicos, pensamos hacer énfasis en la ultraestructura, cuyo cono­ cimiento es básico hoy día para manejar los protozoos, comQ animales unicelulares que son. Igualmente tratamos de difundir en nuestro medio la clasificación ac­ tual, que difiere tanto de la que se sigue estudiando. y por último, tratamos de reunir en un solo trabajo toda la infor­ mación bibliográfica venezolana, ya que es sabido que nuestros autores se ven precisados a publicar en revistas foráneas, y esto se ha acentuado en los últimos diez (10) años.

    1 Exploring the male-induced female reproduction of Schistosoma mansoni in a novel medium Jipeng Wang1, Rui Chen1, James Collins1 1) UT Southwestern Medical Center. Schistosomiasis is a neglected tropical disease caused by schistosome parasites that infect over 200 million people. The prodigious egg output of these parasites is the sole driver of pathology due to infection. Female schistosomes rely on continuous pairing with male worms to fuel the maturation of their reproductive organs, yet our understanding of their sexual reproduction is limited because egg production is not sustained for more than a few days in vitro. Here, we explore the process of male-stimulated female maturation in our newly developed ABC169 medium and demonstrate that physical contact with a male worm, and not insemination, is sufficient to induce female development and the production of viable parthenogenetic haploid embryos. By performing an RNAi screen for genes whose expression was enriched in the female reproductive organs, we identify a single nuclear hormone receptor that is required for differentiation and maturation of germ line stem cells in female gonad. Furthermore, we screen genes in non-reproductive tissues that maybe involved in mediating cell signaling during the male-female interplay and identify a transcription factor gli1 whose knockdown prevents male worms from inducing the female sexual maturation while having no effect on male:female pairing. Using RNA-seq, we characterize the gene expression changes of male worms after gli1 knockdown as well as the female transcriptomic changes after pairing with gli1-knockdown males. We are currently exploring the downstream genes of this transcription factor that may mediate the male stimulus associated with pairing.

  • Ultrastructural Observations on the Oncomiracidium Epidermis and Adult Tegument of Discocotyle Sagittata, a Monogenean Gill Parasite of Salmonids
    Parasitology Research https://doi.org/10.1007/s00436-020-07045-z FISH PARASITOLOGY - ORIGINAL PAPER Ultrastructural observations on the oncomiracidium epidermis and adult tegument of Discocotyle sagittata, a monogenean gill parasite of salmonids Mohamed Mohamed El-Naggar1,2 & Richard C Tinsley3 & Jo Cable2 Received: 14 September 2020 /Accepted: 28 December 2020 # The Author(s) 2021 Abstract During their different life stages, parasites undergo remarkable morphological, physiological, and behavioral “metamorphoses” to meet the needs of their changing habitats. This is even true for ectoparasites, such as the monogeneans, which typically have a free-swimming larval stage (oncomiracidium) that seeks out and attaches to the external surfaces of fish where they mature. Before any obvious changes occur, there are ultrastructural differences in the oncomiracidium’s outer surface that prepare it for a parasitic existence. The present findings suggest a distinct variation in timing of the switch from oncomiracidia epidermis to the syncytial structure of the adult tegument and so, to date, there are three such categories within the Monogenea: (1) Nuclei of both ciliated cells and interciliary cytoplasm are shed from the surface layer and the epidermis becomes a syncytial layer during the later stages of embryogenesis; (2) nuclei of both ciliated cells and interciliary syncytium remain distinct and the switch occurs later after the oncomiracidia hatch (as in the present study); and (3) the nuclei remain distinct in the ciliated epidermis but those of the interciliary epidermis are lost during embryonic development. Here we describe how the epidermis of the oncomiracidium of Discocotyle sagittata is differentiated into two regions, a ciliated cell layer and an interciliary, syncytial cytoplasm, both of which are nucleated.

  • 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.

Families are listed in the same order as in Nelson (1994), with species names following in alphabetical order. The common names of British fishes mostly follow Wheeler (1978). Common names of foreign fishes are taken from Froese & Pauly (2002). Species in square brackets are referred to in the text but are not found in British waters. Fishes restricted to fresh water are shown in bold type. Fishes ranging from fresh water through brackish water to the sea are underlined; this category includes diadromous fishes that regularly migrate between marine and freshwater environments, spawning either in the sea (catadromous fishes) or in fresh water (anadromous fishes). Not indicated are marine or freshwater fishes that occasionally venture into brackish water.
