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...

Abstract: A fauna of quill mites of the subfamily Picobiinae (Acari: Syringophilidae) associated with African birds is revised. Two new monotypic genera are proposed, Gunabopicobia gen. n. for Picobia zumpti Lawrence, 1959 and Lawrencipicobia gen. n. for Picobia poicephali Skoracki et Dabert, 2002. These new genera differ from other genera of the subfamily by the following features: in females of Gunabopicobia, propodonotal setae vi are situated anterior to the level of setae ve; the narrow lateral propodonotal shields bear bases of setae vi, ve, si and se; the bases of setae...

Abstract: The host immune response to parasitic infections plays an important role in controlling multiplication of the parasite and reducing clinical symptoms and life-threatening complications. Nitric oxide (NO), an important innate immune factor and classic Th1 immune effector, may play a role in inhibiting plasmodium infection. In this study, we used two different approaches (L-Arginine [precursor of NO] and NOC5 [short-time NO donor]) to prove the roles of NO in malaria infection. We used 6-8 week-old female BALB/c mice infected with the rodent malaria Plasmodium yoelii Landau, Michel et Adam, 1968 - strain 17XL (P.y17XL) - as a model....

Folia Parasitologica 60[3] 218-224 (2013) | 10.14411/fp.2013.024

Abstract: Zoonotic cutaneous leishmaniasis (ZCL) is an expanding disease and a public health issue in Iran. In the present study, rate of natural infection of rodent populations with Leishmania was investigated in six endemic foci including 28 villages in Golestan, Esfahan, Yazd, Fars, Khuzestan and Ilam provinces. A total of 593 rodents were captured and identified as Rhombomys opimus (n = 325), Meriones libycus (n = 171), Meriones persicus (n = 27), Tatera indica (n = 37), Nesokia indica (n = 12), Rattus rattus (n = 13) and Mus musculus (n = 8). Microscopic examinations...

Folia Parasitologica 60[3] 225-231 (2013) | 10.14411/fp.2013.025

Abstract: The rock agama, Laudakia caucasia Eichwald (Agamidae) is host to Plasmodium caucasica sp. n. and Saurocytozoon agamidorum sp. n. in western Pakistan. Plasmodium caucasica is characterized by very large meronts, 11-21 by 8-17 µm that produce 32-67 merozoites, which nearly fill the host erythrocyte, and smaller, ovoid to elongate gametocytes, 6-14 by 2.5-6 µm, with length by width (LW) 21-55 µm2, and L/W ratio 1.0-4.0. Host cells are usually mature erythrocytes. In Azerbaijan, P. caucasica parasitizes immature erythroid cells. Dimensions of meronts are 10-16 by 6-12 µm, and merozoite...

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...

Blood flukes (Digenea: Aporocotylidae) of walking catfishes (Siluriformes: Clariidae): new genus and species from the Mekong River (Vietnam) with comments on related catfish aporocotylids

Triet Nhat Truong, Stephen A. Bullard

Folia Parasitologica 60[3] 237-247 (2013) | 10.14411/fp.2013.027

Abstract: Nomasanguinicola canthoensis gen. et sp. n. infects the branchial vessels of bighead catfish, Clarias macrocephalus Günther (Siluriformes: Clariidae), in the Mekong River near Can Tho, southern Vietnam. Nomasanguinicola differs from all other genera of fish blood flukes (Digenea: Aporocotylidae) by the combination of lacking body spines and by having an anterior sucker with two flanking columns of large denticles, an intestine comprising several short papilla-like caeca, an inverse U-shaped uterus, and an ootype located near the separate genital pores. The new species has an ootype that is posterior to the level of the...

Folia Parasitologica 60[3] 248-256 (2013) | 10.14411/fp.2013.028

Abstract: This paper describes Regoella brevis gen. n. et. sp. n. (Proteocephalidea: Monticelliinae), a parasite of the intestine of the barred sorubim Pseudoplatystoma fasciatum (Linnaeus) from the Paraná River basin. The new genus is placed in the Monticelliinae because of the cortical position of the genital organs. It differs from all known genera included in the Monticelliinae by the following combination of characters: 1) a quadrangular scolex with a truncated conical apex and formed by four lobes separated by grooves; 2) uniloculate suckers of inverted triangular shape possessing a small cone-shaped projection at each corner of...

Prochristianella mattisi sp. n. (Trypanorhyncha: Eutetrarhynchidae) from the wedgenose skate, Dipturus whitleyi (Rajiformes: Rajidae), from Tasmania (Australia)

Folia Parasitologica 60[3] 257-263 (2013) | 10.14411/fp.2013.029

Abstract: A new species of Prochristianella Dollfus, 1946 is described from the spiral intestine of the wedgenose skate, Dipturus whitleyi (Iredale) (Rajiformes: Rajidae), off the north-western coast of Tasmania (Australia). Prochristianella mattisi sp. n. is characterised by an acraspedote scolex, two oval bothria, elongate, bent bulbs, a retractor muscle inserting at the base of each bulb and the presence of gland-cells within the bulbs and prebulbar organs. The tentacular armature is typical heteroacanthous, heteromorphous, with a characteristic basal oncotaxy and a metabasal armature with hooks first increasing and then decreasing...

Folia Parasitologica 60[3] 264-272 (2013) | 10.14411/fp.2013.030

Abstract: The aim of this study was to determine the accuracy and precision of McMaster method with Raynaud's modification in the detection of the eggs of the nematodes Toxocara canis (Werner, 1782) and Trichuris ovis (Abildgaard, 1795) in faeces of dogs. Four variants of McMaster method were used for counting: in one grid, two grids, the whole McMaster chamber and flotation in the tube. One hundred sixty samples were prepared from dog faeces (20 repetitions for each egg quantity) containing 15, 25, 50, 100, 150, 200, 250 and 300 eggs of T. canis and T. ovis in 1 g of faeces. To compare the influence of kind...
