First species of Ophiotaenia (Cestoda: Proteocephalidea) from Madagascar: O. georgievi sp. n., a parasite of the endemic snake Leioheterodon geayi (Colubridae)
Alainde Chambrier, Morgane Ammann, Tomáš Scholz
Folia Parasitologica 57[3] 197-205 (2010) | DOI: 10.14411/fp.2010.026 
Ophiotaenia georgievi sp. n. (Proteocephalidea: Proteocephalinae) is described from the intestine of endemic colubrid snake Leioheterodon geayi Mocquard (Colubridae) from Antananarivo in Madagascar. The new species is the first species of Ophiotaenia La Rue, 1911 reported from Madagascar. It differs from all Ophiotaenia species parasitic in African snakes in the possession of a three-layered embryophore of eggs (other African species have two-layered embryophore). Furthermore, O. georgievi can be distinguished by the number of testes (92-140), width of the scolex (225-235 µm), total body length (57 mm), cirrus-sac...

Mustafa Yaman, Renate Radek, Jaroslav Weiser, Çiçek Aydin
Folia Parasitologica 57[3] 233-236 (2010) | DOI: 10.14411/fp.2010.031
A new Microsporidium sp. infects Rhizophagus grandis Gyllenhall, a beetle which preys on the bark beetle Dendroctonus micans Kugellan in Turkey. Mature spores are single, uninucleate, oval in shape (3.75 ± 0.27 µm in length by 2.47 ± 0.13 µm in width), with a subapically fixed polar filament. The polar filament is anisofilar, coiled in 7-8 normal and 3-4 reduced coils. Other characteristic features of the microsporidium are the four/five nuclear divisions to form 16/32 (commonly 16) spores, subpersistent sporophorous vesicles (pansporoblasts) remaining till formation of the endospore, and the vesicles...

Bohumil Sak, Martin Kváč, Klára Petrželková, Dana Květoňová, Kateřina Pomajbíková, Martin Mulama, John Kiyang, David Modrý
Folia Parasitologica 58[2] 81-86 (2011) | DOI: 10.14411/fp.2011.008
Two hundred and seventeen captive great apes (150 chimpanzees, Pan troglodytes; 14 bonobos, Pan paniscus; 53 western gorillas, Gorilla gorilla) and 20 personnel from thirteen European zoos and two African sanctuaries were sampled and examined in order to determine the occurrence of Enterocytozoon bieneusi and species of Encephalitozoon in faecal specimens and to compare the epidemiological situation between zoos and sanctuaries. Microsporidia were detected at all sampling sites. Sequence analyses of ITS amplicons generated by using microsporidia-specific primers determined the presence of microsporidia in 87 samples...
A new species of Taeniacanthus (Copepoda: Taeniacanthidae) parasitic on two pufferfish species, Marilyna meraukensis and M. darwinii (Teleostei: Tetraodontidae), from Australia
Danny Tang
Folia Parasitologica 58[3] 233-239 (2011)
A new species of Taeniacanthidae (Copepoda, Cyclopoida), Taeniacanthus kiemae sp. n., is described based on adult female and male specimens collected from the branchial cavity wall of Marilyna meraukensis (de Beaufort) and M. darwinii (Castelnau) (Teleostei, Tetraodontidae) caught in Australian waters. The new species differs from its congeners by having the following combination of characters in the adult female: 1) maxilla armed with a stout terminal process and two small elements; 2) multiple rows of spinules on the large pectinate process of the antenna; 3) an extremely long and thin maxilliped claw; 4) second exopodal segment...

Šárka Mašová, Vlastimil Baruš, František Moravec
Folia Parasitologica 58[4] 318-321 (2011) | DOI: 10.14411/fp.2011.032
First-stage larvae of camallanid nematodes Procamallanus (Procamallanus) laeviconchus (Wedl, 1862) and Procamallanus (Procamallanus) sp. from naturally infected Distichodus niloticus (Hasselquist) and Clarias gariepinus (Burchell), respectively, from Lake Turkana, Kenya (new geographical records) are described, being for the first time studied by scanning electron microscopy. Larvae of both species are characterised by the presence of a dorsal cephalic tooth, four submedian cephalic papillae and a pair of amphids, and by the elongate tail with several terminal digit-like processes. The latter formations...
Two new species of Protogyrodactylus (Monogenoidea: Dactylogyridae) from the gills of Gerres nigri (Teleostei: Gerreidae) from Senegal
Walter A. Boeger, Arfang Diamanka, Antoine Pariselle, Luciana Patella
Folia Parasitologica 59[1] 59-63 (2012) | DOI: 10.14411/fp.2012.009
Protogyrodactylus ethiopicus sp. n. and P. kritskyi sp. n. are described from the gills of Gerres nigri Günther (Gerreidae, Perciformes) captured from the estuary of the Sine-Saloum River (Senegal, West Africa). These new species differ from previously described species within the genus by a mid- or dextro-ventral vaginal opening (dextral in all other species). They are part of a morphological species group within Protogyrodactylus Johnston et Tiegs, 1922 that has the tip of the superficial root of the ventral anchor resembling a hook and two anterior projections on the anterior margin of the ventral bar. Protogyrodactylus...

Rui Guan, Zhongyuan Shen, Feng Zhu, Darui Chen, Jiao Zhang, Jiange Hou, Shinan Dong, Xudong Tang, Li Xu
Folia Parasitologica 59[2] 87-92 (2012) | DOI: 10.14411/fp.2012.013
Microsporidia are a group of obligate intracellular unicellular eukaryotes that can parasitize a wide variety of other eukaryotes ranging from protists to invertebrates and vertebrates. In this study, we examined the microsporidium Nosema sp. isolated from the mulberry pest, Hemerophila atrilineata Butler, 1881, named herein "Nosema sp. HA". The fresh spores were long oval in shape, 3.8 ± 0.4 μm in length and 1.9 ± 0.3 μm in width. Analysis of tissue infection of silkworm, Bombyx mori Linnaeus, 1758, indicated that the midgut, Malpighian tubules, muscle, fat body, silk glands, hemocytes, nerve...

Piotr Solarczyk, Anna C. Majewska, Bożena Moskwa, Władysław Cabaj, Miroslawa Dabert, Piotr Nowosad
Folia Parasitologica 59[3] 237-240 (2012)
A total of 181 faecal samples were collected from wild cervids in two regions of Poland. Giardia cysts were detected in one faecal specimen from red deer and in two samples from roe deer. Fragments of the β-giardin (bg) triose phosphate isomerase (tpi) and glutamate dehydrogenase (gdh) genes were successfully amplified from the Giardia isolate obtained from red deer, whereas only amplicons of bg and gdh were obtained from Giardia isolates derived from two roe deer. The result of genotyping and phylogenetic analysis showed that the G. duodenalis isolate from red deer belonged to sub-assemblage...
Cucolepis cincta gen. n. et sp. n. (Cestoda: Cyclophyllidea) from the squirrel cuckoo Piaya cayana Lesson (Aves: Cuculiformes) from Paraguay
Anna J. Phillips, Jean Mariaux, Boyko B. Georgiev
Folia Parasitologica 59[4] 287-294 (2012) | DOI: 10.14411/fp.2012.040
Cucolepis gen. n. is erected as monotypic for Cucolepis cincta sp. n., a new species of cyclophyllidean cestode of the family Paruterinidae. The new species is described from the squirrel cuckoo, Piaya cayana Lesson (Aves: Cuculiformes), taken from two localities in Paraguay in 1984 and 1985. This new genus is most similar to the genus Triaenorhina Spasskii et Shumilo, 1965 in terms of the hook morphology and large epiphyseal structures extending from both the handle and guard, but differs in several aspects of the strobilar morphology, such as the shape of the cirrus sac, genital atrium, uterus and paruterine organ. The...
Pseudocapillaria (Pseudocapillaria) moraveci sp. n. (Nematoda: Capillariidae) from the stomach of Gobius paganellus (Perciformes: Gobiidae) from Vigo estuary (NW Spain)
Raúl Iglesias, Luisa Centeno, Nuria García, José M. García-Estévez
Folia Parasitologica 60[2] 135-140 (2013) | DOI: 10.14411/fp.2013.014
Abstract: Pseudocapillaria moraveci sp. n. (Nematoda, Capillariidae) is described from the stomach of Gobius paganellus Linnaeus (Perciformes, Gobiidae) from rocky shores of the Vigo estuary (Northwest Atlantic coast of Spain). Scanning electron microscopy reveals the absence of a dorsal cuticular membrane interconnecting the caudal lobes of male, thus confirming the assignment of this new species to the nominotypical subgenus Pseudocapillaria Freitas, 1959. Pseudocapillaria moraveci can be easily differentiated from other marine congeneric species belonging to subgenera Pseudocapillaria and Ichthyocapillaria Moravec,...

Simon Haarder, Kasper Jørgensen, Per Walter Kania, Alf Skovgaard, Kurt Buchmann
Folia Parasitologica 60[2] 177-180 (2013) | DOI: 10.14411/fp.2013.020
Abstract: Freshwater pulmonate snails from three locations in Lake Furesø north of Copenhagen were screened for infection with furcocercariae (by shedding in the laboratory) and recovered parasite larvae were diagnosed by molecular methods (by performing PCR of rDNA and sequencing the internal transcribed spacer [ITS] region). Overall prevalence of infection in snails was 2%. Recovered cercariae from Lymnaea stagnalis (Linnaeus) were diagnosed as Diplostomum pseudospathaceum Niewiadomska, 1984 (prevalence 4%) and cercariae from Radix balthica (Linnaeus) as D. mergi (Dubois, 1932) (prevalence 2%). Pathogen-free rainbow...
The complete mitochondrial genome of Pallisentis celatus (Acanthocephala) with phylogenetic analysis of acanthocephalans and rotifers
Ting Shuang Pan, Pin Nie
Folia Parasitologica 60[3] 181-191 (2013) | DOI: 10.14411/fp.2013.021
Abstract: Acanthocephalans are a small group of obligate endoparasites. They and rotifers are recently placed in a group called Syndermata. However, phylogenetic relationships within classes of acanthocephalans, and between them and rotifers, have not been well resolved, possibly due to the lack of molecular data suitable for such analysis. In this study, the mitochondrial (mt) genome was sequenced from Pallisentis celatus (Van Cleave, 1928), an acanthocephalan in the class Eoacanthocephala, an intestinal parasite of rice-field eel, Monopterus albus (Zuiew, 1793), in China. The complete mt genome sequence of P. celatus is 13855...

Abdel-Azeem S. Abdel-Baki, Saleh Al-Quraishy, Heba M. Abdel-Haleem
Folia Parasitologica 60[3] 232-236 (2013) | DOI: 10.14411/fp.2013.026
Abstract: Four out of twenty (20%) specimens of the lizard Scincus hemprichii Wiegmann, collected in Saudi Arabia were infected with a previously undescribed species of Choleoeimeria. Oocysts of Choleoeimeria jazanensis sp. n. are cylindroidal, 26 × 15 µm, with a smooth bilayered wall and a shape index of 1.7. Oocyst residuum and micropyle are absent. Sporocysts are subspherical, 10 × 7 µm, with a shape index of 1.3. The Stieda body is absent. Sporozoites are banana-shaped, 10 × 3 µm, with one refractile body and enclosed the fine granulated sporocyst residuum. The endogenous development is confined...
A new species of Heterochondria (Copepoda: Chondracanthidae) parasitic on many-banded sole, Zebrias fasciatus (Pleuronectiformes: Soleidae) from Korea, with a key to the species of the genus
Seong Yong Moon, Ho Young Soh
Folia Parasitologica 60[4] 365-371 (2013) | DOI: 10.14411/fp.2013.038
Abstract: A new species of Chondracanthidae (Copepoda: Cyclopoida), Heterochondria orientalis sp. n., is described based on specimens of both sexes collected from the gill rakers and the inner side of the operculum of the many-banded sole, Zebrias fasciatus (Basilewsky), from the Yellow Sea, Korea. The new species resembles most closely H. zebriae (Ho, Kim et Kuman, 2000), but can be distinguished from this species and other congeners by the shape of the trunk and length of the antenna, the number of teeth on the mandible and the terminal process of the maxilla, and the structure of the male antennule and maxilliped. Heterochondria...

Fouzia El Hafidi, Ouafae Berrada Rkhami, Isaure de Buron, Jean-Dominique Durand, Antoine Pariselle
Folia Parasitologica 60[5] 433-440 (2013) | DOI: 10.14411/fp.2013.046
Abstract: Gill monogenean species of Ligophorus Euzet et Suriano, 1977 were studied from the teleost Mugil cephalus Linneaus (Mugilidae) from the Mediterranean and Atlantic coasts of Morocco. We report the presence of L. mediterraneus from both the Mediterranean and Atlantic coast and L. cephali and L. maroccanus sp. n. from the Atlantic coast only. The latter species, which is described herein as new, resembles L. guanduensis but differs from this species mainly in having a shorter penis compared to the accessory piece, a proportionally longer extremity of the accessory piece and a less developed heel....
Description of Sarcocystis lari sp. n. (Apicomplexa: Sarcocystidae) from the great black-backed gull, Larus marinus (Charadriiformes: Laridae), on the basis of cyst morphology and molecular data
Petras Prakas, Liuda Kutkienė, Dalius Butkauskas, Aniolas Sruoga, Mečislovas Žalakevičius
Folia Parasitologica 61[1] 11-17 (2014) | DOI: 10.14411/fp.2014.002
A morphological type of Sarcocystis cysts found in one of two examined great black-backed gull, Larus marinus (Linnaeus) (Laridae), is considered to represent a new species for which the name Sarcocystis lari sp. n. is proposed and its description is provided. The cysts are ribbon-shaped, very long (the largest fragment found was 6 mm long) and relatively narrow (up to 75 μm). Under a light microscope the cyst wall reaches up to 1 μm and seems to be smooth. Using a computerized image analysis system, knolls, which resemble protrusions on the wall surface, are visible. Lancet-shaped cystozoites measure in average 6.9...

R. Philip Scheibel, François Catzeflis, F. Agustín Jiménez
Folia Parasitologica 61[3] 242-254 (2014) | DOI: 10.14411/fp.2014.032
The trichostrongylid nematode Travassostrongylus scheibelorum sp. n. from the Linnaeus' mouse opossum, Marmosa murina (Linnaeus) (type host), and the woolly mouse opossum, Marmosa demerarae (Thomas), from French Guiana is described. The nematodes have a synlophe with ridges frontally oriented from right to left, six dorsal and six ventral, at midbody; seven dorsal and seven ventral posterior to the vulva, and two cuticular thickenings within the lateral spaces; a long dorsal ray and a pointed cuticular flap covering the vulva. This is the 12th species of Travassostrongylus Orloff, 1933, which includes species featuring ridges...
Huffmanela hamo sp. n. (Nematoda: Trichosomoididae: Huffmanelinae) from the dagger-tooth pike conger Muraenesox cinereus off Japan
Jean-Lou Justine, Takashi Iwaki
Folia Parasitologica 61[3] 267-271 (2014) | DOI: 10.14411/fp.2014.029
Huffmanela hamo sp. n. is described from eggs only, which were found in black spots in the somatic musculature of a dagger-tooth pike conger, Muraenesox cinereus (Forsskål), caught off Japan. The eggs are 66-77 µm (mean 72 µm) in length and 33-38 µm (mean 35 µm) in width. The surface of the eggs is smooth and bears neither envelope nor filaments. The species is distinguished from other members of the genus by the dimensions of its eggs and the characteristics of their surface. This is the first species of Huffmanela Moravec, 1987 to be described from an anguilliform fish, and the twentieth nominal species...
Life cycle of the fish parasite Gnathia maxillaris (Crustacea: Isopoda: Gnathiidae)
Coral Hispano, Patrici Bultó, Anicet R. Blanch
Folia Parasitologica 61[3] 277-284 (2014) | DOI: 10.14411/fp.2014.026
The taxonomic classification of some parasitic isopods of the family Gnathiidae has been revised in the last years. However, their biological cycles have been described only partially or incompletely. Gnathia maxillaris (Montagu, 1804) is one of the most studied species, but certain aspects of its life cycle are still poorly known. A detailed study on the life cycle of G. maxillaris was carried out over several years by sampling larvae from an infestation of large volume aquaria at the Aquarium of Barcelona. At the same time, a system of in vitro cultivation of G. maxillaris was developed, which provided new data to complete...
Conflict between morphology and molecular data: a case of the genus Caryophyllaeus (Cestoda: Caryophyllidea), monozoic tapeworms of cyprinid fishes
Eva Bazsalovicsová, Ivica Králová-Hromadová, Jan Brabec, Vladimíra Hanzelová, Mikuláš Oros, Tomáš Scholz
Folia Parasitologica 61[4] 347-354 (2014) | DOI: 10.14411/fp.2014.035
Molecular analysis of an extensive specimen collection of morphologically distinct tapeworms of the genus Caryophyllaeus Gmelin, 1790 (Cestoda: Caryophyllidea), parasites of cyprinid fishes in the Palaearctic Region, brought evidence of host-related plasticity in critical morphological characters widely used for species circumscription and classification of these tapeworms. The results obtained here do not support the traditionally used morphological concept of species-defining characters of the order Caryophyllidea Carus, 1863, especially due to high morphological plasticity of the scolex and the anterior end of the body. Several morphotypes...
Three new gonad-infecting species of Philometra (Nematoda: Philometridae) parasitic in Lutjanus spp. (Lutjanidae) in the northern Gulf of Mexico off Florida, USA
František Moravec, Micah Bakenhaster, Emma J. Fajer-Ávila
Folia Parasitologica 61[4] 355-369 (2014) | DOI: 10.14411/fp.2014.041
Based on light and scanning electron microscopical studies, three new gonad-infecting species of Philometra Costa, 1845 (Nematoda: Philometridae) are described from marine fishes of the genus Lutjanus Bloch (Perciformes: Lutjanidae) in the northern Gulf of Mexico: P. longispicula sp. n. from the ovary of the northern red snapper L. campechanus (Poey) (type host) and silk snapper L. vivanus (Cuvier); P. latispicula sp. n. from the ovary and rarely testes of the grey snapper L. griseus (Linnaeus); and P. synagridis sp. n. (only males available) from the...
Effect of purified condensed tannins from pine bark on larval motility, egg hatching and larval development of Teladorsagia circumcincta and Trichostrongylus colubriformis (Nematoda: Trichostrongylidae)
Abdul-Lateef Molan
Folia Parasitologica 61[4] 371-376 (2014) | DOI: 10.14411/fp.2014.036
The effects of condensed tannins (CTs) extracted from pine bark on egg hatching, larval development and the viability of infective L3 larvae of Trichostrongylus colubriformis (Giles, 1892) and Teladorsagia circumcincta (Stadelmann, 1894) (syn. Ostertagia circumcincta) were evaluated using in vitro bioassays. Significant inhibitory effects of CTs were obtained on the viability of the infective larvae, egg hatching and larval development of both nematodes. In all bioassays, the larval stages of Te. circumcincta were significantly (P < 0.05) more susceptible to the inhibitory effects of CT than those of Tr. colubriformis....
A new genus and species of Heligmonellidae (Nematoda: Trichostrongylina) parasitic in Delomys dorsalis (Rodentia: Sigmodontinae) from Misiones, Argentina
María Celina Digiani, John M. Kinsella
Folia Parasitologica 61[5] 473-478 (2014) | DOI: 10.14411/fp.2014.043
Alippistrongylus bicaudatus gen. et sp. n. (Nematoda: Heligmonellidae) is described from the striped Atlantic forest rat, Delomys dorsalis (Hensel) (Rodentia: Sigmodontinae), from the province of Misiones in Argentina. The new genus and species is characterised by a synlophe of 21 unequal ridges in both sexes without a gradient in size, with two ridges weakly sclerotised and oriented perpendicularly in the dorsal left quadrant; males with a highly dissymmetrical bursa with a hypertrophied right lobe, and females with a dorsal conical appendage just posterior to the vulva, conferring a two-tailed appearance to the female worms.

We studied variations in the abundance of parasitic spinturnicid mites in relation to the gender, age and body condition of bats living in different habitats. Populations of Spinturnix myoti Kolenati, 1856 (Acari: Spinturnicidae), an ectoparasite of the bat Myotis myotis (Borkhausen) (Mammalia: Chiroptera), were investigated in two types of roosts differing in microclimatic conditions: caves (low temperature and high humidity) and attics (high temperature and low humidity). Our data suggest that bats from cave nursery colonies harbour more parasites than those from attic colonies, irrespective of host sex or age. In underground colonies,...

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...

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...
