The influence of latent toxoplasmosis on women's reproductive function: four cross-sectional studies

©árka Kaňková, Jaroslav Flegr, Pavel Calda

Folia Parasitologica 62:041 (2015) | 10.14411/fp.2015.041

Several studies have investigated the association between infection with Toxoplasma gondii (Nicolle et Manceaux, 1908), pregnancy and fertility, but the results of studies focused on the fertility are rather ambiguous. Here we report results of four new cross-sectional studies. The studies were performed in the General University Hospital, Prague (study A with n = 1 165, and study C with n = 317), in private clinics of the Centre of Reproductive Medicine, Prague (study B with n = 1 016), and in a population of Czech and Slovak volunteers from the Facebook page 'Guinea Pigs' willing to participate in various basic science studies (study D with...

Two new species of Euryhaliotrema Kritsky et Boeger, 2002 (Monogenea: Dactylogyridae) from Lutjanus russellii (Bleeker) and L. argentimaculatus (Forsskål) (Teleostei: Lutjanidae) in the South China Sea

Yuan Sun, Tingbao Yang

Folia Parasitologica 62:040 (2015) | 10.14411/fp.2015.040

Euryhaliotrema russellum sp. n. and Euryhaliotrema tenuiaccessorium sp. n. are described from the gills of Lutjanus russellii (Bleeker) and L. argentimaculatus (Forsskål), respectively, in the South China Sea. Euryhaliotrema russellum sp. n. differs from all other members of Euryhaliotrema Kritsky et Boeger, 2002 by its unique male copulatory organ, a straight tube with a bulbous base and without an accessory piece. Euryhaliotrema tenuiaccessorium sp. n. differs from its congeners by having a copulatory organ with a bulbous base, a meandering copulatory tube with clockwise coil having less than...

Passive sinking into the snow as possible survival strategy during the off-host stage in an insect ectoparasite

Sirpa Kaunisto, Hannu Ylönen, Raine Kortet

Folia Parasitologica 62:038 (2015) | 10.14411/fp.2015.038

Abiotic and biotic factors determine success or failure of individual organisms, populations and species. The early life stages are often the most vulnerable to heavy mortality due to environmental conditions. The deer ked (Lipoptena cervi Linnaeus, 1758) is an invasive insect ectoparasite of cervids that spends an important period of the life cycle outside host as immobile pupa. During winter, dark-coloured pupae drop off the host onto the snow, where they are exposed to environmental temperature variation and predation as long as the new snowfall provides shelter against these mortality factors. The other possible option is to passively sink...

Cystoidosoma hermaphroditus sp. n., the first representative of the quill mite family Ascouracaridae (Acari: Astigmata: Pterolichoidea) from an owl (Aves: Strigiformes)

Fabio Akashi Hernandes, Barry M. OConnor

Folia Parasitologica 62:037 (2015) | 10.14411/fp.2015.037

The mite family Ascouracaridae Gaud et Atyeo, 1976 contains large-sized mites (mostly > 1 mm) which live inside the quills of birds of several orders. To date, no representative of this family has been found associated with the order Strigiformes (owls). In this paper, a new species of this family, Cystoidosoma hermaphroditus sp. n., is described from the tropical screech owl, Megascops choliba (Vieillot) (Aves: Strigiformes) from Brazil. This species is unique in having an external spermaduct, a primary duct and a rudimentary bursa copulatrix present in males. This is the first astigmatan feather mite described from...

Trichomonosis in Eurasian sparrowhawks in the Czech Republic

Tomáą Kunca, Pavla Smejkalová, Ivan Čepička

Folia Parasitologica 62:035 (2015) | 10.14411/fp.2015.035

Pigeon, doves and songbirds are hosts of the parasite Trichomonas gallinae (Rivolta, 1878), which causes avian trichomonosis. Raptors are infected when they digest infected prey. A high percentage of the diet of Eurasian sparrowhawk Accipiter nisus (Linnaeus) is comprised of birds. During the breeding season 2012 and 2013, we clinically tested 298 nestling Eurasian sparrowhawks from urban and rural areas of the Czech Republic for the presence of trichomonads. Sparrowhawk nestlings in the urban area were more infected (32.9%) than in the rural area (12.2%) in 2012 (χ2 = 6.184, P = 0.045). The number of infected nestlings...

Wazid Hassan, B. Surendra Nath

Folia Parasitologica 62:034 (2015) | 10.14411/fp.2015.034

The utility of inter simple sequence repeat-PCR (ISSR-PCR) assay in the genetic characterisation and elucidation of the phylogenetic relationship of different microsporidian isolates infecting tropical tasar silkworm, Antheraea mylitta Drury, is demonstrated. A total of 22 different microsporidians collected from the diseased tasar silkworms from Jharkhand state of India were analysed using morphological characters and ISSR-PCR. Observations spores under phase contrast microscope revealed oval to elongate in shape with length ranging from 3.8 μm to 5.1 μm and width from 2.6 μm to 3.3 μm. All the microsporidian isolates except MIJ-1gC...

Macroparasites and their communities of the European eel Anguilla anguilla (Linnaeus) in the Czech Republic

Frantiąek Moravec, Tomáą Scholz

Folia Parasitologica 62:033 (2015) | 10.14411/fp.2015.033

This paper summarises the results of parasitological examinations of the European eel Anguilla anguilla (Linnaeus) in the Czech Republic, carried out at the Institute of Parasitology, Czech Academy of Sciences (previously the Czechoslovak Academy of Sciences) within the period of 50 years (1958-2008). Even though this survey is limited to the Czech Republic, it provides extensive data probably incomparable with any other study anywhere regarding the number of eels examined and parasites found. A total of 723 eels was examined from 42 localities that belong to all of the three main river drainage systems in the country, i.e. the Elbe, Danube...

A new feather mite of the genus Dolichodectes (Astigmata: Proctophyllodidae) from Hippolais polyglotta (Passeriformes: Acrocephalidae) in Spain

Sergey V. Mironov, Jorge Doña, Roger Jovani

Folia Parasitologica 62:032 (2015) | 10.14411/fp.2015.032

A new feather mite species, Dolichodectes hispanicus sp. n. (Astigmata: Proctophyllodidae), is described from the Melodious Warbler Hippolais polyglotta (Vieillot) (Passeriformes: Acrocephalidae) in Spain. The new species is closest to the type species of the genus, D. edwardsi (Trouessart, 1885) from the Grear Reed-Warbler Acrocephalus arundinaceus (Linnaeus) (Acrocephalidae). Adults of D. hispanicus differ from those of D. edwardsi by dimensional characteristics, in particular, by having shorter aedeagus that does not extend to the anal suckers in males and shorter hysteronotal shield in females. Tritonymphs...

Yuriy Kuzmin, Louis H. du Preez, Kerstin Junker

Folia Parasitologica 62:031 (2015) | 10.14411/fp.2015.031

Based on material collected from Rhinella cf. margaritifera (Laurenti) and Rhi. marina (Linnaeus) (Anura: Bufonidae) during a parasite survey of the herpetofauna of French Guiana, updated descriptions of Rhabdias androgyna Kloss, 1971 and R. fuelleborni Travassos, 1926 are presented. In addition to metrical data, which may overlap in closely related species, emphasis is placed on qualitative characters. Rhabdias androgyna is distinguished by the unique presence of an outer and inner cephalic cuticular inflation, a shoulder-like broadening of the body at the anterior end, a wide and shallow buccal...

Helminth parasites of Artemia franciscana (Crustacea: Branchiopoda) in the Great Salt Lake, Utah: first data from the native range of this invader of European wetlands

Stella Redón, Nicole J. Berthelemy, Yasen Mutafchiev, Francisco Amat, Boyko B. Georgiev, Gergana P. Vasileva

Folia Parasitologica 62:030 (2015) | 10.14411/fp.2015.030

The present study is the first survey on the role of Artemia franciscana Kellogg as intermediate host of helminth parasites in its native geographical range in North America (previous studies have recorded nine cestode and one nematode species from this host in its invasive habitats in the Western Mediterranean). Samples of Artemia franciscana were collected from four sites in the Great Salt Lake (GSL), Utah, across several months (June-September 2009). A. franciscana serves as intermediate host of five helminth species in this lake. Four of them are cestodes: three hymenolepidids, i.e. Confluaria podicipina (Szymanski,...

Parasite richness in fish larvae from the nearshore waters of central and northern Chile

Gabriela Muñoz, Mauricio F. Landaeta, Pamela Palacios-Fuentes, Zambra López, María Teresa González

Folia Parasitologica 62:029 (2015) | 10.14411/fp.2015.029

In the present study, we determine the presence of parasites in fish larvae collected from nearshore waters along the northern and central coast of Chile. The parasites were identified to the lowest possible taxonomic level based on morphological and molecular analyses. The fish sample was composed of 5 574 fish larvae. Of these, 3% harboured only larval ectoparasitic copepods whereas no endoparasites were found in the 1 141 fish evaluated for this group of parasites. The parasitic copepods collected were initially classified as 'morphotypes' according to differences in morphological characteristics. They were then analysed using molecular techniques...

Heliconema anguillae Yamaguti, 1935, a physalopterid nematode found in Japanese eels: taxonomic resurrection with a note on the third-stage larva from intertidal crabs in western Japan

Hirotaka Katahira, Kazuya Nagasawa

Folia Parasitologica 62:028 (2015) | 10.14411/fp.2015.028

A parasitic nematode from the stomach of Japanese eel Anguilla japonica Temminck et Schlegel in western Japan, previously identified as Heliconema longissimum (Ortlepp, 1922), was morphologically re-examined and compared with the previous descriptions. In addition, the third-stage larva of this nematode is described, based on the specimens of encapsuled larvae found in musculature of two crabs, Hemigrapsus sp. and Perisesarma bidens (De Haan), caught from the upper-intertidal zone of the same locality. As a result of the morphological observation, seven pairs of postcloacal papillae in adult males are confirmed. This matches...

Ultrastructure of the anterior organ and posterior funnel-shaped canal of Gyrocotyle urna Wagener, 1852 (Cestoda: Gyrocotylidea)

Larisa G. Poddubnaya, Roman Kuchta, Glenn A. Bristow, Tomáą Scholz

Folia Parasitologica 62:027 (2015) | 10.14411/fp.2015.027

Using scanning and transmission electron microscopy, ultrastructure of the anterior organ and posterior funnel-shaped canal of Gyrocotyle urna Wagener, 1852 (Cestoda: Gyrocotylidea) from ratfish, Chimaera monstrosa (Holocephali), was studied for the first time. The proper anterior organ is localised at a short distance (about 170 µm) from an apical pore surrounded by a receptor field, whereas its distal end is marked by a muscular sphincter. The tegumental surface of this organ is covered with short filitriches of irregular length; large area of muscle layers traverse beneath the tegumental layer. The funnel-shaped canal of G....

Morphological and attachment changes of Lamellodiscus theroni (Monogenea: Diplectanidae) during its post-larval development on fish

Neus Sánchez-García, Juan A. Raga, Francisco E. Montero

Folia Parasitologica 62:026 (2015) | 10.14411/fp.2015.026

Species of the genus Lamellodiscus Johnston et Tiegs, 1922 (Monogenea: Diplectanidae) are characterised by a complex haptor bearing many different attachment elements: two pairs of main hooks joined by medial bars, 14 peripheral marginal hooks and one or two lamellodiscs, formed by several overlapping sclerotised plates (lamellae). These haptoral structures appear gradually during parasite development and, therefore, attachment strategies vary with developmental stage. The main aim of this work was to study the developmental changes of Lamellodiscus theroni Amine, Euzet et Kechemir-Issad, 2007 under experimental conditions, with special...

An additional genus and two additional species of Forticulcitinae (Digenea: Haploporidae)

Michael J. Andres, Stephen S. Curran, Thomas J. Fayton, Eric E. Pulis, Robin M. Overstreet

Folia Parasitologica 62:025 (2015) | 10.14411/fp.2015.025

Forticulcita platana sp. n. and Forticulcita apiensis sp. n. are described from Mugil liza Valenciennes in Argentina, and from Mugil cephalus Linnaeus in Salt Springs, Florida, USA, respectively. Supplemental material relating to the hermaphroditic sac of Forticulcita gibsoni Blasco-Costa, Montero, Balbuena, Raga et Kostadinova, 2009 is provided from a specimen isolated from M. cephalus off Crete, Greece. Forticulcita platana can be distinguished from all species of Forticulcita Overstreet, 1982 except F. gibsoni, based on possessing small pads or gland cells along the hermaphroditic duct. It...

A comparative study of Ligophorus uruguayense and L. saladensis (Monogenea: Ancyrocephalidae) from Mugil liza (Teleostei: Mugilidae) in southern Brazil

Natalia C. Marchiori, Antoine Pariselle, Joaber Pereira Jr., Jean-François Agnèse, Jean-Dominique Durand, Maarten P.M. Vanhove

Folia Parasitologica 62:024 (2015) | 10.14411/fp.2015.024

Representatives of Ligophorus Euzet et Suriano, 1977 were found on the gills of Mugil liza Valenciennes caught in southern Brazil. They were identified as Ligophorus uruguayense Failla Siquier et Ostrowski de Núñez, 2009 and Ligophorus saladensis Marcotegui et Martorelli, 2009, even though specific identification proved to be difficult due to inconsistencies in some diagnostic features reported for these two species. Therefore, a combined morphological and molecular approach was used to critically review the validity of these species, by means of phase contrast and confocal fluorescence microscopical examination of...

Screening for anthelmintic resistance in equid strongyles (Nematoda) in Romania

Mihai Cernea, Romeo T. Cristina, Laura C. Ştefănuţ, Luís M. Madeira de Carvalho, Marian A. Taulescu, Vasile Cozma

Folia Parasitologica 62:023 (2015) | 10.14411/fp.2015.023

Resistance to anthelmintic medication of equid strongyles is a worldwide phenomenon and for this reason systematic investigations of resistant parasite populations are necessary. The purpose of the present study was to investigate the presence and distribution of equid strongyles resistant to the anthelmintics used in Romania, as well as the pre-treatment and post-treatment prevalence of species of strongylid nematodes. The Faecal Egg Count Reduction Test was performed between 2010 and 2013 on a total number of 588 horses and 23 donkeys from 26 locations (subgroups). Animals of the first group (I) consisting of subgroups no. 1-11 were treated with...

Proteomic analysis of potential immunoreactive proteins from muscle larvae and adult worms of Trichinella spiralis in experimentally infected pigs

Justyna Bien, Wladyslaw Cabaj, Bozena Moskwa

Folia Parasitologica 62:022 (2015) | 10.14411/fp.2015.022

The present study was undertaken to identify potentially immunoreactive proteins of the muscle larvae (ML) and adult stage (Ad) of the nematode Trichinella spiralis Owen, 1835. To identify immunoreactive proteins that are specifically recognised by anti-Trichinella antibodies, ML and Ad crude extracts and their excretory-secretory (E-S) products were subjected to sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblot with serum samples from pigs experimentally infected with T. spiralis. A total of 18 bands were selected for final identification by liquid chromatography-tandem mass spectrometry. To further...

Effect of dietary guild (frugivory and insectivory) and other host characteristics on ectoparasite abundance (mite and nycteribiid) of chiropterans

Albert Luguterah, Eric Adjei Lawer

Folia Parasitologica 62:021 (2015) | 10.14411/fp.2015.021

Ectoparasites are an important factor in bat health due to emergent diseases and their associated threats to global public health. The diverse foraging habits of bats expose them to different surfaces which may influence ectoparasite infestations. In spite of these, most studies often overlook dietary specialisations when observing ectoparasite loads. The present paper quantitatively investigates whether foraging strategies as well as other host characteristics (sex, age, trunk and patagial area) influence ectoparasite (nycteribiids and mites) loads of bats. Ectoparasite counts and morphometric data were taken from mist net captures of bats. We then...

Observations on sporulation of Eimeria bovis (Apicomplexa: Eimeriidae) from the European bison Bison bonasus: effect of temperature and potassium dichromate solution

Anna M. Pyziel, Aleksander W. Demiaszkiewicz

Folia Parasitologica 62:020 (2015) | 10.14411/fp.2015.020

The present study was designed to determine the influence of temperature and the addition of potassium dichromate solution (K2Cr2O7) on the efficiency of sporulation of Eimeria bovis (Zublin, 1908), a coccidian species most commonly diagnosed in European bison Bison bonasus (Linnaeus). Sporulation under conventional conditions (2.5% dichromate solution, 23 °C) was completed on the fourth day of incubation (control), whereas the oocyst development took two days more at the temperature of 18 °C, and two days less at 28 °C. Additionally, experimental sporulation of E. bovis at the temperature of 23...

Damselflies (Zygoptera) as paratenic hosts for Serpinema trispinosum and its report from turtle hosts from Oklahoma, USA

Crystal M. Wiles, Matthew G. Bolek

Folia Parasitologica 62:019 (2015) | 10.14411/fp.2015.019

Third-stage larvae of the nematode Serpinema trispinosum (Leidy, 1852) were collected from the midgut of four of five species of adult damselflies (Zygoptera) from a non-irrigated restored semipermanent wetland located in Stillwater, Oklahoma, USA. Of the four infected damselfly species, prevalence and mean abundance was highest for the southern spreadwing, Lestes disjunctus australis Walker (10%, 0.2 ± 0.8) and lowest for the familiar bluet, Enallagma civile (Hagen) (2.5%, 0.04 ± 0.3); whereas mean intensities were lowest for the citrine forktail, Ischnura hastata (Say) (1.5 ± 0.5) and the eastern...

A new species of Wallinia Pearse, 1920 (Digenea: Allocreadiidae) in Astyanax mexicanus (Characidae) from Mexico revealed by morphology and sequences of the 28S ribosomal RNA gene

Gerardo Pérez-Ponce de León, Ulises Razo-Mendivil, Berenit Mendoza-Garfias, Miguel Rubio-Godoy, Anindo Choudhury

Folia Parasitologica 62:018 (2015) | 10.14411/fp.2015.018

Wallinia mexicana sp. n. is described from the Mexican tetra, Astyanax mexicanus (De Filippi) (Characidae Weitzman), from two localities in northern Mexico. The new species can be distinguished from the two congeneric species, described from small-bodied characids in South and Central America, mainly by the posterior extent of the vitelline follicles (halfway between the posterior testis and the end of the caeca), by having a larger oesophagus, testes that are always oblique, and eye-spot remnants. The distinct status of the new species was confirmed by molecular data (28S rRNA gene sequences). Phylogenetic analysis suggests the new species...

The occurrence of metacercariae of Petasiger (Digenea: Echinostomatidae) in an unusual site, within the lateral line scales of cyprinid fishes

Kálmán Molnár, David I. Gibson, Gábor Cech, Melitta Papp, Petra Deák-Paulus, Lajos Juhász, Norbert Tóth, Csaba Székely

Folia Parasitologica 62:017 (2015) | 10.14411/fp.2015.017

During a regular veterinary inspection of fishes from Lake Balaton, Hungary, echinostomatid metacercariae (Digenea), with collar spines characteristic of species of the genera Petasiger Dietz, 1909 and Paryphostomum Dietz, 1909, were found in the lateral line scales of a roach Rutilus rutilus (Linnaeus), an apparently unique site. In a subsequent examination of 586 fishes from 20 different species, similar infections were found in 11 species. The infection was virtually restricted to the lateral line scales, other scales being infected only incidentally. These encysted metacercariae had 27 collar spines, including eight larger...

Characterisation of microsatellite loci in two species of lice, Polyplax serrata (Phthiraptera: Anoplura: Polyplacidae) and Myrsidea nesomimi (Phthiraptera: Amblycera: Menoponidae)

Jana Martinů, Veronika Roubová, Milena Nováková, Vincent S. Smith, Václav Hypąa, Jan ©tefka

Folia Parasitologica 62:016 (2015) | 10.14411/fp.2015.016

Polymorphic microsatellite loci were characterised for two louse species, the anopluran Polyplax serrata Burmeister, 1839, parasitising Eurasian field mice of the genus Apodemus Kaup, and the amblyceran Myrsidea nesomimi Palma et Price, 2010, found on mocking birds endemic to the Galápagos Islands. Evolutionary histories of the two parasites show complex patterns influenced both by their geographic distribution and through coevolution with their respective hosts, which renders them prospective evolutionary models. In P. serrata, 16 polymorphic loci were characterised and screened across 72 individuals from four European...

Association between latent toxoplasmosis and clinical course of schizophrenia - continuous course of the disease is characteristic for Toxoplasma gondii-infected patients

Tuncay Çelik, Şükrü Kartalci, Özgür Aytaş, Gülay Aral Akarsu, Harika Gözükara, Süheyla Ünal

Folia Parasitologica 62:015 (2015) | 10.14411/fp.2015.015

The aim of the present study was to investigate the association between various clinical aspects of schizophrenia and seropositivity against Toxoplasma gondii (Nicolle et Manceaux, 1908). We selected 94 patients with schizophrenia and investigated the seropositivity rate for anti-T. gondii IgG antibodies by ELISA. Clinical parameters of schizophrenic patients such as illness type and status, clinical course, awareness of the illness and need for electroconvulsive therapy (ECT) were compared with their serological status. Anti-T. gondii IgG antibodies were detected in 43 (46%) of schizophrenic patients. Chronic patients had a rate...

James M. Forwood, James O. Harris, Matt Landos, Marty R. Deveney

Folia Parasitologica 62:013 (2015) | 10.14411/fp.2015.013

Ichthyophthirius multifiliis Fouquet, 1876, a ciliate parasite, is a cosmopolitan and problematic parasite of cultured freshwater fish. Each geographical isolate of I. multifiliis has variations in life cycle timing under different abiotic water conditions, such as temperature and salinity. We assessed the effects of salinity and temperature on the development and the preferred settlement site of a temperate Australian isolate of I. multifiliis. The time until theront release was significantly different between each temperature; development time was longest at 5 °C with a mean time of 189 h and decreased to a mean time of 11.7 h at 30...

Four new species of Acanthobothrium van Beneden, 1850 are described from guitarfish, Rhynchobatus cf. djiddensis (Forsskål), collected from the Gulf of Oman and Persian Gulf. Acanthobothrium janineae sp. n., a category 1 species, differs from all congeners in category 1 by having a long vagina extending into the vas deferens and different, proglottid and testis number except Acanthobothrium hypermekkolpos Fyler et Caira, 2010. Acanthobothrium fylerae sp. n., a category 1 species, can be differentiated by a combination of characters including the total length, proglottid and testis number, cirrus sac shape, and...
