Wojciech Piasecki, Agnieszka Sękowska-Jakubowska, Ewa Sobecka

Folia Parasitologica 53[3] 211-216 (2006) | DOI: 10.14411/fp.2006.027  

Achtheres percarum von Nordmann, 1832 and Achtheres sandrae Gadd, 1901 (Lernaeopodidae) are common parasitic copepods infecting fishes in Eurasia. The former is specific to perch, Perca fluviatilis L., while the latter, to zander, Sander lucioperca (L.). Until recently these copepods have been regarded a single species. The present study was intended to analyse details of male morphology and provide their complete descriptions with differential diagnosis. Males of A. percarum and A. sandrae were collected from perch and zander at Lake Dąbie (north-western Poland). The males of A. sandrae are larger than...

Carla Muñoz-Antoli, Antoni Marin, Amparo Vidal, Rafael Toledo, José Guillermo Esteban

Folia Parasitologica 55[2] 122-126 (2008) | DOI: 10.14411/fp.2008.016  

Euparyphium albuferensis and Echinostoma friedi cercarial infectivity to four species of sympatric snails was examined under single- or multiple-choice laboratory conditions to show the level of parasite-snail host compatibility. Radix peregra, Lymnaea fuscus, Physella acuta and Gyraulus chinensis act as second intermediate hosts of both parasite species although different cercarial transmission success (CTS) was observed. In single-host experiments, R. peregra and P. acuta showed a high degree of compatibility with E. albuferensis, while only P. acuta in the case of E. friedi....

Lenka Fišerová, Kateřina Černá, Helena Horká, Jan Kopecký

Folia Parasitologica 55[2] 150-154 (2008) | DOI: 10.14411/fp.2008.020  

A previously reported procedure for the introduction of Borrelia spirochetes into tick larvae by immersion in a suspension of spirochetes was tested on Ixodes ricinus (L.) ticks and three of the most medically important European Borrelia genomic species, B. burgdorferi sensu stricto, B. garinii and B. afzelii. The procedure was compared with "classical" infection of nymphs by feeding on infected mice. Both methods yielded comparable results (infection rate 44-65%) with the exception of B. afzelii, which produced better results using the immersion method (44%) compared with feeding on infected mice (16%)....

Systematic status of Philometra jordanoi (López-Neyra, 1951) and some other congeneric species previously identified as Philometra lateolabracis (Yamaguti, 1935) (Nematoda: Philometridae)

František Moravec

Folia Parasitologica 55[2] 159-160 (2008) | DOI: 10.14411/fp.2008.022  

The systematic status of the gonad-infecting Philometra species previously reported as P. lateolabracis (Yamaguti, 1935) from marine fishes in the Mediterranean region and off New Caledonia is evaluated with respect to the recent redescription of P. lateolabracis from the type host in Japan. Philometra jordanoi (López-Neyra, 1951) is revalidated to accommodate the nematodes from Epinephelus marginatus, whereas the philometrids from other European hosts (Mycteroperca rubra and Seriola dumerili), as well as those from the gonads of Epinephelus cyanopodus and E. fasciatus off New Caledonia,...

The development of Myxobolus pavlovskii (Myxozoa: Myxobolidae) includes an echinactinomyxon-type actinospore

Szilvia Marton, Edit Eszterbauer

Folia Parasitologica 58[2] 157-163 (2011) | DOI: 10.14411/fp.2011.015  

Echinactinomyxon-type actinospores were found in a mixed-species oligochaete culture originating from the Temperate Water Fish Hatchery near Budapest, Hungary. On the basis of DNA sequence analysis, the actinospores were identified as Myxobolus pavlovskii (Akhmerov, 1954), the 18S rDNA sequence from myxospores of which is available in GenBank. Silver carp Hypophthalmichthys molitrix (Valenciennes) fry specimens were successfully infected by cohabitation with the echinactinomyxon-releasing oligochaetes, which confirmed the molecular data congruence. The echinactinomyxons and the myxospores that developed in the gills of exposed fish fry...

Marlus Bueno-Silva, Walter A. Boeger

Folia Parasitologica 61[3] 213-222 (2014) | DOI: 10.14411/fp.2014.028  

Based on molecular markers (COII and ITS1-ITS2) and morphological data, we describe three new Neotropical species of Gyrodactylus von Nordmann, 1832 from Scleromystax barbatus (Quoy et Gaimard) and Scleromystax macropterus (Regan) from southern Brazil. The three new species can be distinguished from each other by sequences of both molecular markers and morphology of hooks and anchors. Gyrodactylus bueni sp. n. is characterised by having hook with shaft curved, heel straight, shelf straight, toe pointed, anchor with superficial root slender, elongate and male copulatory organ armed with two rows of spinelets. Gyrodactylus...

The systematic status of Piscinema barakensis [sic] Gambhir et Ng, 2014 and Rhabdochona carpiae Nimbalkar, Deolalikar et Kamtikar, 2013, two nematodes recently described from freshwater fishes in India

František Moravec

Folia Parasitologica 61[3] 266 (2014) | DOI: 10.14411/fp.2014.045  

Based on the original description, the nematode genus Piscinema Gambhir et Ng, 2014 and its type species, P. barakensis [sic] Gambhir et Ng, 2014 (probably a misidentified physalopterid larvae), are removed from the Philometridae, where they were allocated; they are considered a genus inquirendum and incertae sedis and a species inquirenda, respectively. The poorly described nematode Rhabdochona carpiae Nimbalkar, Deolalikar et Kamtikar, 2013 (Rhabdochonidae) appears largely fabricated and is regarded a species dubia.

Jurairat Jongthawin, Pewpan M. Intapan, Oranuch Sanpool, Penchom Janwan, Lakkhana Sadaow, Tongjit Thanchomnang, Sakhone Laymanivong, Wanchai Maleewong

Folia Parasitologica 63:002 (2016) | DOI: 10.14411/fp.2016.002  

We report the molecular-phylogenetic identification of larvae of the nematode genus Gnathostoma Owen, 1836 collected from a snake, Ptyas koros Schlegel, in Laos and adult worms from the stomach of a dog in Thailand. DNA was extracted and amplified targeting the partial cox1 gene and the ITS-2 region of ribosomal DNA. Phylogenetic analyses indicated that all five advanced third-stage larvae and seven adult worms were Gnathostoma spinigerum Owen, 1836. This is also the first molecular evidence of infection with G. spinigerum in a snake from Laos.
