Ultrastructure of spermiogenesis and mature spermatozoon of Triaenorhina rectangula (Cestoda: Cyclophyllidea: Paruterinidae)
Aneta Yoneva, Katia Georgieva, Pavel N. Nikolov, Yana Mizinska, Boyko B. Georgiev, Stoyanka R. Stoitsova
Folia Parasitologica 56[4] 275-283 (2009) | DOI: 10.14411/fp.2009.032 
Ultrastructural characters of spermiogenesis and mature spermatozoon of Triaenorhina rectangula (Fuhrmann, 1908) are examined by transmission electron microscopy. Spermiogenesis follows the Bâ and Marchand's Type III spermiogenesis of cestodes. The process begins with the formation of a differentiation zone containing two centrioles and a cytoplasmic protrusion. The centrioles are associated with vestigial striated roots. One of the centrioles develops a free flagellum externally to the cytoplasmic protrusion. After a slight rotation, the free flagellum fuses with the cytoplasmic protrusion. In the final stage of spermiogenesis, a single crested...

The examination of the type series of Ophiotaenia gallardi (Johnston, 1911) (syn. Proteocephalus gallardi Johnston, 1911) revealed that it is a mixture of two species of different genera. Lectotype of Ophiotaenia gallardi is designated and the species is redescribed on the basis of it, conspecific paralectotypes and additional materials. The remaining part of the type series belongs to Vandiermenia gen. n. (Acanthotaeniinae), with V. beveridgei sp. n. as the type- and only species. The new genus differs from all other acanthotaeniine genera, i.e. Rostellotaenia Freze, 1963, Acanthotaenia von Linstow,...
A new species of Litomosoides (Nematoda: Onchocercidae), parasite of Nectomys palmipes (Rodentia: Cricetidae: Sigmodontinae) from Venezuela: description, molecular evidence, Wolbachia pipientis screening
Ricardo Guerrero, Odile Bain, Coralie Martin, Michela Barbuto
Folia Parasitologica 58[2] 149-156 (2011) | DOI: 10.14411/fp.2011.014
The onchocercid filaria Litomosoides taylori sp. n. is described from the sigmodontine cricetid Nectomys palmipes Allen et Chapman in northeast Venezuela. A voucher specimen of the new species was used for molecular analysis of the coxI and 12S rDNA genes, and screened for the presence of the endobacterium Wolbachia pipientis. Litomosoides taylori belongs to the "sigmodontis group" of Litomosoides and a combination of characters can be used to distinguish it from the remaining 18 species forming this group. Among the five Nectomys species, all living near running water, N. squamipes also harbours...

Folia Parasitologica 59[1] 21-26 (2012) | DOI: 10.14411/fp.2012.004
In this study, a loop-mediated isothermal amplification (LAMP) assay was established to detect Toxoplasma gondii DNA in mice infected with T. gondii PRU strain. This LAMP assay was based on the sequence of highly repetitive B1 gene. The detection limit of T. gondii LAMP assay was 1 pg of T. gondii DNA, which was evaluated using 10-fold serially diluted DNA of cultured parasites. The LAMP assay was also highly specific for T. gondii and able to detect T. gondii DNA in urine of mice treated with dexamethasone at 90 day post infection (p.i.), although this assay could not detect the DNA in mice urine 2-6 days...

Ahmed M. Ghoneim
Folia Parasitologica 60[1] 75-78 (2013) | DOI: 10.14411/fp.2013.009
Trafficking of the rhoptry chimeric protein RhopH2-GFP, which contains RhopH2 signal peptide plus the downstream five amino acids, was dissected by treating parasites with Brefeldin A at three different time points. Twenty eight hrs-stage trophozoites accumulated the chimera within the parasite endoplasmic reticulum. In 32 hrs-stage schizonts, the chimera was distributed in the parasite cytoplasm but not in the parasitophorous vacuole. In 36 hrs stage-schizonts, the chimera was detected in the individual parasitophorous vacuoles of the developing merozoites and, in contrary to non-treated parasites, no immature rhoptry vesicles could be detected in...

Folia Parasitologica 60[2] 149-154 (2013) | DOI: 10.14411/fp.2013.016
Abstract: A myxosporean producing actinospores of the tetractinomyxon type in Hydroides norvegicus Gunnerus (Serpulidae) in Denmark was identified as a member of the family Parvicapsulidae based on small-subunit ribosomal DNA (SSU rDNA) sequences. Myxosporean samples from various Danish and Norwegian marine fishes were examined with primers that detect the novel myxosporean. Sprattus sprattus (Linnaeus) and Clupea harengus Linnaeus (Teleostei, Clupeidae) were found to be infected. The sequences of this parvicapsulid from these hosts were consistently slightly different (0.8% divergence), but both these genotypes were found in H. norvegicus....
The expression of malarial invasion-related molecules is affected by two different nitric oxide-based treatments
Li Zheng, Hui Feng, Di Liu, Yan-Yan Pan, Ya-Ming Cao
Folia Parasitologica 60[3] 213-217 (2013) | DOI: 10.14411/fp.2013.023
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....

Abstract: Recent collections of cestode parasites from two species of the myliobatid genus Aetomylaeus Garman from several localities in the Pacific Ocean resulted in the discovery of two new species of Halysioncum Caira, Marques, Jensen, Kuchta et Ivanov, 2013. Halysioncum gibsoni sp. n. from Aetomylaeus maculatus (Gray) in the South China Sea off Borneo differs from all of its congeners in having the following combination of characters: 27 apical hooks (14 type A and 13 type B hooks), 11-12 lateral hooklets, 22-28 spines per column on the cephalic peduncle, testes distributed in a single column and an internal seminal...
Prevalence of mutation and phenotypic expression associated with sulfadoxine-pyrimethamine resistance in Plasmodium falciparum and Plasmodium vivax
Haytham A. Zakai, Wajihullah Khan, Umme Asma
Folia Parasitologica 60[4] 372-376 (2013) | DOI: 10.14411/fp.2013.039
Abstract: Therapeutic efficacy of sulfadoxine-pyrimethamine (SP), which is commonly used to treat falciparum malaria, was assessed in isolates of Plasmodium falciparum (Welch, 1897) and Plasmodium vivax (Grassi et Feletti, 1890) of Aligarh, Uttar Pradesh, North India and Taif, Saudi Arabia during 2011-2012. Both the species showed mutations in dihydrofolate reductase (DHFR) enzyme as they have common biochemical drug targets. Mutation rate for pfdhfr was higher compared to pvdhfr because the drug was mainly given to treat falciparum malaria. Since both the species coexist, P. vivax was also exposed to SP due to faulty species diagnosis...

Gyrodactylidae and Dactylogyridae (Monogenoidea) are described or reported from three species of Characidium Reinhardt (Crenuchidae), small species of Characiformes, from streams located in southern Brazilian states. Gyrodactylus carolinae sp. n. (Gyrodactylidae) is described from the body surface of Characidium lanei Travassos (type host), C. pterostictum Gomez, and Characidium sp. from streams in the states of Paraná and São Paulo. This new species closely resembles species of Gyrodactylus von Nordmann, 1832 described from species of Poeciliidae, from which it differs by the morphology of the hooks...

Two new species of feather mites are described from nightjars (Caprimulgiformes: Caprimulgidae) of Brazil: Hartingiella neotropica sp. n. (Xolalgidae) described from Hydropsalis parvula (Gould) and Paragabucinia brasiliensis sp. n. (Gabuciniidae) from H. albicollis (Gmelin). The former differs from the type species by having, in males, the anterior projections on epimerites III towards setae 3b and the adanal shield bearing setae ps3 present; in both sexes, a pair of small sclerites situated posterior to setae se have flat suprategumental processes. Paragabucinia brasiliensis sp....

Single-miracidium infections of Lymnaea cubensis (Pfeiffer) from Guadeloupe with the giant liver fluke Fascioloides magna (Bassi, 1875) (Digenea) were carried out during five successive snail generations to determine if this lymnaeid might sustain complete larval development of the parasite. Controls were constituted by a French population of Galba truncatula (Müller) (a single generation) infected according to the same protocol. It was recorded that prevalence and intensity of F. magna infection in L. cubensis progressively increased from F1 to F5 generations. Cercarial shedding of F. magna was noted only...

A new species of Merizocotyle Cerfontaine, 1894 (Monogenea: Monocotylidae) is described from the nasal tissues of three deep sea rajid skates: the southern thorny skate, Amblyraja doellojuradoi (Pozzi), broadnose skate, Bathyraja brachyurops (Fowler), and yellownose skate, Zearaja chilensis (Guichenot), collected off Buenos Aires Province, Argentina, southwest Atlantic Ocean. Two additional species of sympatric rajid, the white-dotted skate, Bathyraja albomaculata (Norman), and the Patagonian skate, Bathyraja macloviana (Norman), were also examined but no merizocotylines were found. The taxonomy of the Merizocotylinae...
