(Digenea: Aporocotylidae) infects the heart of the smalltooth sawfish, Pristis pect- inata Latham (Rhinopristiformes: Pristidae), in the eastern Gulf of Mexico. Specimens of the new genus, along with the other blood flukes that infect batoids are similar by having an inverse U-shaped intestine and a curving testis as well as by lacking tegumental spines. The new genus differs from all of the other blood flukes infecting batoids by having an elongate body (>50 × longer than wide), a testis having >100 curves, and an ovary wholly anterior to the uterus. It differs from Ogawaia glaucostegi Cutmore, Cribb et Yong, 2018, the only other blood fluke infecting a rhinopristiform, by having a body that is >50 × (vs <30 ×) longer than wide, a testis that is >75 × (vs <40 ×) longer than wide and has >100 (vs <70) curves, an ovary wholly anterior to (vs lateral and dorsal to) the seminal vesi- cle, a uterus wholly posterior to (vs overlapping and lateral to both) the testis and ovary, and a sinuous (vs convoluted) uterus. -

A sample of 42 fishes was examined in this study Which was represented by 36 small- mouth bass, five yellow perch, and one green sunfish. Al- together, nine different species of helminth parasites from the three phyla were recovered. The larval stage of the bass tapeworm (plerocercoids) were present in all the 42 fishes examined and were found to be most damaging. The extent of damage is greater in the females than in the males of the same age group. A study on larval lengths revealed that gonads, especially the ovaries, are better suited for the growth of these larvae. As the fish advance in age the larvae in the gonads also increase in length. The rate of growth of larvae is approximately three times greater in Prem Shankar Prasad the females than in the males. -

Conservation and Diversification of Small RNA Pathways Within Flatworms Santiago Fontenla1, Gabriel Rinaldi2, Pablo Smircich1,3 and Jose F
Fontenla et al. BMC Evolutionary Biology (2017) 17:215 DOI 10.1186/s12862-017-1061-5 RESEARCH ARTICLE Open Access Conservation and diversification of small RNA pathways within flatworms Santiago Fontenla1, Gabriel Rinaldi2, Pablo Smircich1,3 and Jose F. Tort1* Abstract Background: Small non-coding RNAs, including miRNAs, and gene silencing mediated by RNA interference have been described in free-living and parasitic lineages of flatworms, but only few key factors of the small RNA pathways have been exhaustively investigated in a limited number of species. The availability of flatworm draft genomes and predicted proteomes allowed us to perform an extended survey of the genes involved in small non-coding RNA pathways in this phylum. Results: Overall, findings show that the small non-coding RNA pathways are conserved in all the analyzed flatworm linages; however notable peculiarities were identified. While Piwi genes are amplified in free-living worms they are completely absent in all parasitic species. Remarkably all flatworms share a specific Argonaute family (FL-Ago) that has been independently amplified in different lineages. Other key factors such as Dicer are also duplicated, with Dicer-2 showing structural differences between trematodes, cestodes and free-living flatworms. Similarly, a very divergent GW182 Argonaute interacting protein was identified in all flatworm linages. Contrasting to this, genes involved in the amplification of the RNAi interfering signal were detected only in the ancestral free living species Macrostomum lignano. We here described all the putative small RNA pathways present in both free living and parasitic flatworm lineages. Conclusion: These findings highlight innovations specifically evolved in platyhelminths presumably associated with novel mechanisms of gene expression regulation mediated by small RNA pathways that differ to what has been classically described in model organisms. -

Malatji , Jennifer Lamb, Samson Mukaratirwa School of Life Sciences, College of Agriculture, Engineering and Science, University of KwaZulu-Natal, Westville Campus, Durban 4001, South Africa ARTICLE INFO ABSTRACT Keywords: Lymnaeidae snail species are known to be intermediate hosts of human and livestock helminths parasites, Lymnaeidae especially Fasciola species. Identification of these species and their geographical distribution is important to ITS-2 better understand the epidemiology of the disease. Significant diversity has been observed in the shell mor- Okavango delta (OKD) phology of snails from the Lymnaeidae family and the systematics within this family is still unclear, especially KwaZulu-Natal (KZN) province when the anatomical traits among various species have been found to be homogeneous. Although there are Mpumalanga province records of lymnaeid species of southern Africa based on shell morphology and controversial anatomical traits, there is paucity of information on the molecular identification and phylogenetic relationships of the different taxa. Therefore, this study aimed at identifying populations of Lymnaeidae snails from selected sites of the Okavango Delta (OKD) in Botswana, and sites located in the KwaZulu-Natal (KZN) and Mpumalanga (MP) provinces of South Africa using molecular techniques. Lymnaeidae snails were collected from 8 locations from the Okavango delta in Botswana, 9 from KZN and one from MP provinces and were identified based on phy- logenetic analysis of the internal transcribed spacer (ITS-2). -

Chibwana* and G. Nkwengulila Department of Zoology and Wildlife Conservation, University of Dar es Salaam, PO Box 35064, Dar es Salaam, Tanzania (Received 29 July 2015; Accepted 27 October 2015) Abstract The nervous systems of three Tylodelphys metacercariae (T. mashonense, Tylodelphys spp. 1 and 2) co-occurring in the cranial cavity of the catfish, Clarias gariepinus, were examined by the activity of acetylthiocholine iodide (AcThI), with the aim of better understanding the arrangement of sensillae on the body surface and the nerve trunks and commissures, for taxonomic purposes. Enzyme cytochemistry demonstrated a comparable orthogonal arrangement in the three metacercariae: the central nervous system (CNS) consisting of a pair of cerebral ganglia, from which anterior and posterior neuronal pathways arise and inter- link by cross-connectives and commissures. However, the number of transverse nerves was significantly different in the three diplostomid metacercariae: Tylodelphys sp. 1 (30), Tylodelphys sp. 2 (21) and T. mashonense (15). The observed difference in the nervous system of the three metacercariae clearly separates them into three species. These findings suggest that consistent differences in the transverse nerves of digenean metacercariae could enable the differentiation -

The Trematode Parasites of Marine Mammals
THE TREMATODE PARASITES OF MARINE MAMMALS By Emmett W. Pkice Parasitologist, Zoological Division, Bureau of Animal Industry United States Department of Agriculture The internal parasites of marine mammals have not been exten- sively studied, although a fairly large number of species have been described. In attempting to identify the trematodes from mammals of the orders Cetacea, Pinnipedia, and Sirenia, as represented by specimens in the United States National Museum helminthological collection, it was necessary to review the greater part of the litera- ture dealing with this group of parasitic worms. In view of the fact that there is not in existence a single comprehensive paper on the trematodes of these mammals, and that many of the descrip- tions of species have appeared in publications having more or less limited circulation, the writer has undertaken to assemble descriptions of all trematodes reported from these hosts, with the hope that such a paper may serve a useful purpose in aiding other workers in de- termining specimens at their disposal. In addition to compiling the descriptions of species not available to the writer, two new species, one of which represents a new genus, have been described. Specimens representing 10 of the previously described species have been studied and emendations or additions have been made to the existing descriptions; in a few instances the species have been completely reclescribed. Three species, Distoinwni pallassil Poirier, D. vaUdwim von Lin- stow, and D. am/pidlacewni Buttel-Reepen, have been omitted from this paper despite the fact that they have been reported from ceta- ceans. These species belong in the family Hemiuridae, and since all species of this family are parasites of fishes, the writer feels that their reported occurrence in mammals may be regarded as either errors of some sort or cases of accidental parasitism in which fishes have been eaten by mammals and the fish parasites found in the mammal post-mortem. -
