Janine N. Caira, Claire J. Healy, Fernando P.L. Marques, Kirsten Jensen
Folia Parasitologica 64:008 (2017) | DOI: 10.14411/fp.2017.008
Three genera of rhinebothriideans, previously referred to as New genus 1, New genus 2 and New genus 4, are erected in the the Anthocephaliidae. New genus 1 is established as Divaricobothrium gen. n., with Divaricobothrium tribelum sp. n. as its type species; Echeneibothrium trifidum Shipley et Hornell, 1906 is transferred to the genus as Divaricobothrium trifidum (Shipley et Hornell, 1906) comb. n. This genus is unique among rhinebothriidean genera in bearing bothridia that are posteriorly deeply divided into two lobes with facial loculi but no apical sucker, and a vagina that extends to near the anterior margin of the proglottid....

Jacek Karamon, Krzysztof Stojecki, Małgorzata Samorek-Pieróg, Ewa Bilska-Zajac, Mirosław Rózycki, Ewa Chmurzyńska, Jacek Sroka, Jolanta Zdybel, Tomasz Cencek
Folia Parasitologica 64:007 (2017) | DOI: 10.14411/fp.2017.007
The aim of the present study was to estimate the genetic diversity of the cestode Echinococcus multilocularis Leuckart, 1863 in Poland based on sequence analysis of the mitochondrial genes of worms isolated from red foxes, Vulpes vulpes (Linnaeus). Overall, 83 adults of E. multilocularis from the same number of foxes in different parts of Poland were used for analysis. Sequences of the three mitochondrial genes, cytochrome b (cob), NADH dehydrogenase subunit 2 (nad2) and cytochrome c oxidase subunit 1 (cox1), were analysed. Seventy-four individual biological samples were successfully sequenced....

María de los Milagros Cámara, León Bouvier, Chantal Reigada, Fabio A. Digirolamo, Melisa Sayé, Claudio A. Pereira
Folia Parasitologica 64:006 (2017) | DOI: 10.14411/fp.2017.006
Nucleoside diphosphate kinases (NDPK) are key enzymes involved in the intracellular nucleotide maintenance in all living organisms, especially in trypanosomatids which are unable to synthesise purines de novo. Four putative NDPK isoforms were identified in the Trypanosoma cruzi Chagas, 1909 genome but only two of them were characterised so far. In this work, we studied a novel isoform from T. cruzi called TcNDPK3. This enzyme presents an atypical N-terminal extension similar to the DM10 domains. In T. cruzi, DM10 sequences targeted other NDPK isoform (TcNDPK2) to the cytoskeleton, but TcNDPK3 was localised in glycosomes...

An IgM murine monoclonal antibody (MAb) was obtained against the excretory-secretory antigen (ES-Ag) of in vitro reared protoscoleces of Echinococcus granulosus (Batsch, 1786). Western blotting revealed that the MAb recognised a 20.6 kDa protein of this ES-Ag. The MAb was used in sandwich enzyme-linked immunosorbent assay (s-ELISA) for selective sensitisation of the solid phase with the protoscolex-specific protein from its ES-Ag and somatic antigen (S-Ag) to examine serum samples of 108 cows from a cystic echinococcosis (CE) endemic area for specific antibodies and to compare the results with those from necropsies and an indirect ELISA...
A new genus with two new species of lecanicephalidean tapeworms (Cestoda) from the mangrove whipray, Urogymnus granulatus (Myliobatiformes: Dasyatidae),from the Solomon Islands and northern Australia
Kaylee S. Herzog, Kirsten Jensen
Folia Parasitologica 64:004 (2017) | DOI: 10.14411/fp.2017.004
A new lecanicephalidean genus is erected for cestodes previously recognised as "New Genus 12" (Polypocephalidae) in a phylogenetic analysis of the interrelationship of members of this order. Examination of the cestode fauna of the mangrove whipray, Urogymnus granulatus (Macleay) (Myliobatiformes: Dasyatidae) from the Solomon Islands and northern Australia revealed the existence of specimens representing two new species, consistent in morphology with "New Genus 12." Corollapex gen. n. is unique among the 24 valid lecanicephalidean genera in its possession of an apical organ in the form of an external retractable central disk surrounded...

Cédric Roqueplo, Radu Blaga, Jean-Lou Marié, Isabelle Vallée, Bernard Davoust
Folia Parasitologica 64:003 (2017) | DOI: 10.14411/fp.2017.003
Toxoplasma gondii (Nicolle et Manceaux, 1908) is an obligate intracellular, parasitic protozoan within the phylum Apicomplexa that causes toxoplasmosis in mammalian hosts (including humans) and birds. Since meat of wild boar, Sus scrofa (Linnaeus), has been demonstrated to be a potential source of human infection, a careful evaluation of the prevalence of infection with T. gondii in hunted animals is needed to protect public health. In the Var area in southeastern France, we performed a spatio-temporal survey in order to investigate the prevalence of IgG antibodies in wild boars shot by hunters in the Canjuers military camp during two...

Xinhua Liu, Congjie Hua, Qianqian Zhang, Yuanli Zhao, Dong Zhang, Jinyong Zhang
Folia Parasitologica 64:001 (2017) | DOI: 10.14411/fp.2017.001
Myxobolus taibaiensis sp. n. was found in the inner intestinal wall of common carp, Cyprinus carpio Linnaeus, during the investigation of fish parasite fauna in Lake Taibai, located in the middle reach of the Yangtze River, China. The whitish ellipsoidal plasmodia, up to 2.9 mm long and 1.7 mm wide, developed in the circular muscle layer of the intestinal wall and produced significant compression into adjacent tissues, but no significant inflammatory responses were observed against this infection. Mature spores are oval in frontal view and lemon-like in lateral and apical view, averaging 10.2-11.2 µm (10.8 ± 0.2 µm)...
A new species of Spirorchis MacCallum, 1918 (Digenea: Schistosomatoidea) and Spirorchis cf. scripta from chicken turtle, Deirochelys reticularia (Emydidae), with an emendation and molecular phylogeny of Spirorchis
Jackson R. Roberts, Raphael Orélis-Ribeiro, Kenneth M. Halanych, Cova R. Arias, Stephen A. Bullard
Folia Parasitologica 63:041 (2016) | DOI: 10.14411/fp.2016.041
Chicken turtles, Deirochelys reticularia (Latreille in Sonnini et Latreille) (Testudines: Emydidae) from Alabama, USA were infected by Spirorchis collinsi Roberts et Bullard sp. n. and Spirorchis cf. scripta. The new species is most easily differentiated from its congeners by the combination of having caeca that extend far beyond the genitalia, intercaecal genitalia positioned in the middle portion of the body, a testicular column that nearly abuts the caecal bifurcation, a cirrus sac positioned between the testes and ovary, a massive Mehlis' gland, an elongate, longitudinal metraterm that extends anteriad beyond the level...

Kerstin Junker, Frikkie Calitz, Danny Govender, Boris R. Krasnov, Joop Boomker
Folia Parasitologica 63:040 (2016) | DOI: 10.14411/fp.2016.040
Thirty-two specimens of the Nile crocodile, Crocodylus niloticus Laurenti (Reptilia: Crocodylidae), from the Kruger National Park, South Africa, and its vicinity were examined for pentastomid parasites during 1995 to 1999 and 2010 to 2011. Pentastomid parasites occurred throughout the year and were widespread in the study area with an overall prevalence of 97% and an overall mean abundance of 23.4 (0-81). Pentastome assemblages comprised six species in three sebekid genera: Alofia nilotici Riley et Huchzermeyer, 1995, A. simpsoni Riley, 1994, Leiperia cincinnalis Sambon, 1922, Sebekia cesarisi Giglioli in Sambon,...
A new R package and web application for detecting bilateral asymmetry in parasitic infections
Matthew T. Wayland, James C. Chubb
Folia Parasitologica 63:039 (2016) | DOI: 10.14411/fp.2016.039
When parasites invade paired structures of their host non-randomly, the resulting asymmetry may have both pathological and ecological significance. To facilitate the detection and visualisation of asymmetric infections we have developed a free software tool, Analysis of Symmetry of Parasitic Infections (ASPI). This tool has been implemented as an R package (https://cran.r-project.org/package=aspi) and a web application (https://wayland.shinyapps.io/aspi). ASPI can detect both consistent bias towards one side, and inconsistent bias in which the left side is favoured in some hosts and the right in others. Application of ASPI is demonstrated using previously...

Florian B. Reyda, Claire J. Healy, Andrew R. Haslach, Timothy R. Ruhnke, Tara L. Aprill, Michael P. Bergman, Andrew L. Daigler, Elsie A. Dedrick, Illari Delgado, Kathryn S. Forti, Kaylee S. Herzog, Rebecca S. Russell, Danielle D. Willsey
Folia Parasitologica 63:038 (2016) | DOI: 10.14411/fp.2016.038
Survey work of batoid elasmobranchs in the eastern Atlantic and Indo-Pacific revealed multiple species of a new genus of cestode. Stillabothrium Healy et Reyda gen. n. (Rhinebothriidea: Escherbothriidae) is unique in its possession of an even number of non-medial longitudinal septa in the posterior portion of the bothridia, resulting in a series of loculi that are longer than wide (i.e. vertically oriented) and are arranged in columns. Five new species of Stillabothrium are described, S. ashleyae Willsey et Reyda sp. n., S. davidcynthiaorum Daigler et Reyda sp. n., S. campbelli Delgado, Dedrick...

Tanasak Changbunjong, Suchada Sumruayphol, Thekhawet Weluwanarak, Jiraporn Ruangsittichai, Jean-Pierre Dujardin
Folia Parasitologica 63:037 (2016) | DOI: 10.14411/fp.2016.037
Adult flies of the genus Stomoxys Geoffroy, 1762 (Diptera: Muscidae), especially S. pullus Austen, 1909, S. uruma Shinonaga et Kano, 1966 and S. indicus Picard, 1908, are morphologically similar and sometimes difficult to distinguish when using external morphological characteristics. These species may act as vectors and/or potential vectors of many pathogens (virus, bacteria and protozoa). Their correct identification is important to target the vectors involved in the transmission of the pathogens and also helps in the fly control program.The aim of the present study was to distinguish three species which are difficult to...
A new coccidian parasite of the boodie, Bettongia lesueur (Mammalia: Marsupialia: Potoroidae), from Australia
Frances Hulst, Leah F. Kemp, Jan Šlapeta
Folia Parasitologica 63:036 (2016) | DOI: 10.14411/fp.2016.036
Four of 28 wild boodies or burrowing bettongs, Bettongia lesueur (Quoy et Gaimard) passed oocysts of species of Eimeria Schneider, 1875. The boodies are surviving on off-shore islands and in large predator-proof sanctuaries on the mainland where they were reintroduced. The boodie is a potoroid marsupial extinct from the mainland of Australia due to predation from red foxes and feral cats. Comparison with other species of the genus Eimeria indicates that the coccidium found represents a new species. Sporulated oocyst of Eimeria burdi sp. n. are pyriform, 21.0-24.0 µm (mean 22.6 µm) by 14.0-16.0 µm...

Understanding of the diversity of species of Cryptosporidium Tyzzer, 1910 in tortoises remains incomplete due to the limited number of studies on these hosts. The aim of the present study was to characterise the genetic diversity and biology of cryptosporidia in tortoises of the family Testudinidae Batsch. Faecal samples were individually collected immediately after defecation and were screened for presence of cryptosporidia by microscopy using aniline-carbol-methyl violet staining, and by PCR amplification and sequence analysis targeting the small subunit rRNA (SSU), Cryptosporidium oocyst wall protein (COWP) and actin genes. Out of...
No association between latent toxoplasmosis and multiple body measures in U.S. adults
Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Bruce L. Brown, Dawson W. Hedges
Folia Parasitologica 63:034 (2016) | DOI: 10.14411/fp.2016.034
Toxoplasma gondii (Nicolle et Manceaux, 1908) is an intracellular parasite that can cause ongoing latent infection persisting for the duration of a non-definitive host's life. Affecting approximately one-third of the world's population, latent toxoplasmosis has been associated with neuropsychological outcomes and a previous report suggested an association between latent toxoplasmosis and adult height. Given the large number of people with latent toxoplasmosis and its potential associations with human height, we sought to better understand the association between latent toxoplasmosis and human morphology by evaluating seropositivity for T. gondii...
Histopathological and ultrastructural studies of Myxobolus turpisrotundus from allogynogenetic gibel carp Carassius auratus gibelio in China
Qingxiang Guo, Yanhua Zhai, Zemao Gu, Yang Liu
Folia Parasitologica 63:033 (2016) | DOI: 10.14411/fp.2016.033
During an ongoing systematic survey on species diversity of myxozoans parasitising allogynogenetic gibel carp Carassius auratus gibelio (Bloch) in China, plasmodia were detected in the fins, lip, jaw, gill chamber, gill arches, operculum and oral cavity of infected fish. Combining the morphological and molecular data, the present species was identified as Myxobolus turpisrotundus Zhang, Wang, Li et Gong, 2010. Histopathological examination revealed that despite infecting different organs, M. turpisrotundus always occurred in dermis, demonstrating its affinity to this tissue. Histopathological effect of M. turpisrotundus on...
No association between current depression and latent toxoplasmosis in adults
Shawn D. Gale, Andrew N. Berrett, Bruce Brown, Lance D. Erickson, Dawson W. Hedges
Folia Parasitologica 63:032 (2016) | DOI: 10.14411/fp.2016.032
Changes in behaviour and cognition have been associated with latent infection from the apicomplexan protozoan Toxoplasma gondii (Nicolle et Manceaux, 1908) in both animal and human studies. Further, neuropsychiatric disorders such as schizophrenia have also been associated with latent toxoplasmosis. Previously, we found no association between T. gondii immunoglobulin G antibody (IgG) seropositivity and depression in human adults between the ages of 20 and 39 years (n = 1 846) in a sample representative of the United States collected by the Centers for Disease Control as part of a National Health and Nutrition Examination Survey (NHANES)...

Folia Parasitologica 63:031 (2016) | DOI: 10.14411/fp.2016.031
Coeuritrema Mehra, 1933, previously regarded as a junior subjective synonym of Hapalorhynchus Stunkard, 1922, herein is revised to include Coeuritrema lyssimus Mehra, 1933 (type species), Coeuritrema rugatus (Brooks et Sullivan, 1981) comb. n., and Coeuritrema platti Roberts et Bullard sp. n. These genera are morphologically similar by having a ventral sucker, non-fused caeca, two testes, a pre-testicular cirrus sac, an intertesticular ovary, and a common genital pore that opens dorsally and in the sinistral half of the body. Phylogenetic analysis of the D1-D3 domains of the nuclear large subunit ribosomal DNA (28S) suggested...
Toxoplasmosis in Nigeria: the story so far (1950-2016): a review
John Asekhaen Ohiolei, Clement Isaac
Folia Parasitologica 63:030 (2016) | DOI: 10.14411/fp.2016.030
Toxoplasmosis is caused by intracellular protozoan parasite, Toxoplasma gondii (Nicolle et Manceaux, 1908). Cats and other felids are the definitive hosts. It could be transmitted to man and animals by consumption of infected undercooked meat and contaminated food items including drinking water. Results of toxoplasmosis epidemiological surveys in animals and humans in South-West, North-West, North-East and North-Central Zones of Nigeria have been reported with greater impact on the health of pregnant women and HIV-infected individuals. Meanwhile, studies in states within the South-South and South-East Zones are relatively scanty or non-existent....

Vincenzo Arizza, Francesco Sacco, Debora Russo, Rita Scardino, Marco Arculeo, Melita Vamberger, Federico Marrone
Folia Parasitologica 63:029 (2016) | DOI: 10.14411/fp.2016.029
Endemic Sicilian pond turtles Emys trinacris Fritz, Fattizzo, Guicking, Tripepi, Pennisi, Lenk, Joger et Wink were examined for the presence of haemogregarine parasites. The presence of haemogregarines, occurring mainly in the microgametocyte stage (13.2 ± 0.12 μm in length and 6.4 ± 0.52 μm in width), was observed in approximately 9% of the sampled E. trinacris. Based on the observed morphology and on the sequencing of nuclear 18S rDNA, we identified the parasite as Haemogregarina stepanowi Danilewsky, 1885. Morphometric study of uninfected and infected red blood cells has shown that H. stepanowi induces...
Analysis of structures and epitopes of a novel secreted protein MYR1 in Toxoplasma gondii
Jian Zhou, Gang Lu, Shenyi He
Folia Parasitologica 63:028 (2016) | DOI: 10.14411/fp.2016.028
Toxoplasma gondii (Nicolle et Manceaux, 1908) is an obligate intracellular apicomplexan parasite and can infect warmblooded animals and humans all over the world. Development of effective vaccines is considered the only ideal way to control infection with T. gondii. However, only one live vaccine is commercially available for use in sheep and goats. Thus more effective antigenic proteins are searched for. In the present study we report a novel protein by secreted T. gondii termed Myc regulation 1 (MYR1). The physical and chemical characteristics, epitopes, hydrophilicity and functional sites of MYR1 were analysed by multiple bioinformatic...

We have evaluated the therapeutic effect of a compound mixture of caprylic acid (200 mg/kg fish), organic iron (0.2% of diet) and mannan oligosaccharide (0.4% of diet) in gilthead sea bream, Sparus aurata Linnaeus, infected with Sparicotyle chrysophrii Beneden et Hesse, 1863 in controlled conditions. One hundred and ten reared and S. chrysophrii-free fish (197 g) located in a cement tank were infected by the parasite two weeks following the addition of 150 S. chrysophrii-infected fish (70 g). Growth parameters and gill parasitic load were measured in treated against control fish after a ten-week-period. Differences in final...
A morphological and genetic description of pentastomid infective nymphs belonging to the family Sebekidae Sambon, 1922 in fish in Australian waters
Diane P. Barton, Jess A.T. Morgan
Folia Parasitologica 63:026 (2016) | DOI: 10.14411/fp.2016.026
Infective nymphal stages of the family Sebekidae Sambon, 1922 are reported from four species of fish in Australian waters for the first time. Infected fish were collected from locations in Western Australia, the Northern Territory and north Queensland. The infective nymphs of Alofia merki Giglioli in Sambon, 1922 and Sebekia purdieae Riley, Spratt et Winch, 1990 are reported and described for the first time. The remaining specimens were identified as belonging to the genus Sebekia Sambon, 1922 based on the combination of buccal cadre shape, shape and size of hooks, and overall body size, but could not be attributed to any of the...

Folia Parasitologica 63:023 (2016) | DOI: 10.14411/fp.2016.023
Avian haemosporidians are common vector-borne blood parasites that have been reported in birds all over the world. Investigations of avian haemosporidian parasites are conducted mainly on passerine birds. However, studies that focus on non-passerine avian hosts are important for our understanding of the true diversity, host specificity and genetic variability among these widespread parasites. In the present study, blood samples from a total of 22 raptor birds belonging to two orders, two families and six species from the Central Anatolia Region of Turkey were investigated for three genera of avian haemosporidians (Plasmodium Marchiafava et Celli,...
