Lyme borreliosis (LB) is a serious infectious disease of humans and some domestic animals in temperate regions of the Northern Hemisphere. It is caused by certain spirochetes in the Borrelia burgdorferi sensu lato (s.l.) species complex. The complex consists of 11 species (genospecies). Borrelia burgdorferi sensu stricto (s.s.), Borrelia garinii and Borrelia afzelii are the major agents of human disease. Borrelia burgdorferi s.l. species are transmitted mainly by ticks belonging to the Ixodes ricinus species complex plus a few additional species not currently assigned to the complex. B. burgdorferi infections...

Based on morphological and molecular characterisation, four amoeba strains isolated from organs of freshwater fish were identified as Hartmannella vermiformis Page, 1967. Small subunit rRNA gene sequences of these strains expand the set of corresponding complete and almost complete sequences of this species to twelve. A new species-specific oligonucleotide probe inferred from recently available SSU rRNA gene sequences was designed and successfully tested in tissue lesions produced by one strain of H. vermiformis in experimentally infected fish.
Trilosporoides platessae gen. et sp. n. (Myxozoa: Multivalvulida) in the plaice Pleuronectes platessa (Teleostei: Pleuronectidae) from Denmark
Folia Parasitologica 52 304-306 (2005) | 10.14411/fp.2005.041
A new myxosporean species, Trilosporoides platessae gen. et sp. n. (Multivalvulida), is described from the gallbladder of the plaice Pleuronectes platessa L. (Pleuronectidae) from Denmark. The myxospore of T. platessae is conical in side view, with a 24 µm long, pointed posterior projection. In apical view, the myxospore (diameter 9.4 µm) is round, trilobed and with three spherical polar capsules arranged peripherally, equidistant and opening peripherally through protruding tips. The polar capsules are of different sizes, one often larger than the others (diameter 3.3 µm vs. 2.5 µm). Apart from the long...
A new species of Mymarothecium and new host and geographical records for M. viatorum (Monogenea: Dactylogyridae), parasites of freshwater fishes in Brazil

Folia Parasitologica 52 307-310 (2005) | 10.14411/fp.2005.042
Mymarothecium boegeri sp. n. (Monogenea: Dactylogyridae) is described from the gills of Colossoma macropomum Cuvier (Characidae), collected from the aquaria of the "Centro de Pesquisas em Aquicultura, Departamento Nacional de Obras Contra as Secas (DNOCS)", Pentecoste City, State of Ceará, Brazil. Mymarothecium viatorum Boeger, Piasecki et Sobecka, 2002 is reported from the type host, Piaractus brachypomus (Cuvier) (Characidae) and from a new host, P. mesopotamicus (Holmberg) (Characidae), confirming the occurrence of M. viatorum in the Neotropical Region. The new species differs from the congeneric species...
Morphological characterisation of Paranoplocephala bairdi (Schad, 1954) (Cestoda: Anoplocephalidae) in heather voles Phenacomys spp. and tree voles Arborimus spp., and related species in voles and lemmings (Muridae: Arvicolinae)

Folia Parasitologica 52 311-321 (2005) | 10.14411/fp.2005.043
The taxonomical status of Paranoplocephala bairdi (Schad, 1954)-like cestodes (Anoplocephalidae) in heather voles Phenacomys spp. and tree voles Arborimus spp. (Muridae: Arvicolinae) and their discrimination from five related species of Paranoplocephala is assessed using uni- and multivariate morphometrics. The analyses support the independent status and conspecificity of specimens from Phenacomys spp. and Arborimus spp., and P. bairdi is therefore suggested to be a host-specialist species of heather and tree voles with a wide geographical distribution in North America. A redescription is presented for...

Fine structure of the female reproductive ducts of Cyathocephalus truncatus (Cestoda: Spathebothriidea), from salmonid fish
Larisa G. Poddubnaya, John S. Mackiewicz, Magdaléna Bruňanská, Tomáš Scholz
Folia Parasitologica 52 323-338 (2005) | 10.14411/fp.2005.045
The fine structure of the ovary, ovicapt, oviduct, fertilisation canal, vitelline ducts, vitelline reservoir, ovovitelline duct, ootype and Mehlis' gland, and proximal, middle and distal parts of the uterus of the spathebothriidean cestode, Cyathocephalus truncatus (Pallas, 1781), from salmoniform fish, has been studied for the first time by transmission electron microscopy (TEM). Emphasis was given to characteristics which might shed light on the unclarified phylogenetic position of spathebothriideans, belonging among the most basal tapeworms (Eucestoda). New for cestodes is the finding of a multinucleate cell that plugs the ovicapt lumen....
Rhabdias kongmongthaensis sp. n. (Nematoda: Rhabdiasidae) from Polypedates leucomystax (Amphibia: Anura: Rhacophoridae) in Thailand
Yuriy Kuzmin, Vasyl V. Tkach, Jefferson A. Vaughan
Folia Parasitologica 52 339-342 (2005) | 10.14411/fp.2005.046
Rhabdias kongmongthaensis sp. n. is described based on specimens found in the lungs of the tree frog Polypedates leucomystax (Gravenhorst) (Amphibia: Rhacophoridae) from Kanchanaburi Province, western Thailand. The new species is similar to two North-American species, Rhabdias ranae and R. americanus, by presence of two lateral pseudolabia, each with two inner submedian protuberances. R. kongmongthaensis differs from both species by relative length and shape of the tail, and by its distribution and host specificity. Presence of lateral pseudolabia distinguishes the new species from the geographically closest Rhabdias...
Cucullanus oceaniensis sp. n. (Nematoda: Cucullanidae) from Pacific eels (Anguilla spp.)

Folia Parasitologica 52 343-348 (2005) | 10.14411/fp.2005.047
A new species of parasitic nematode, Cucullanus oceaniensis sp. n., is described from the intestine of the giant mottled eel Anguilla marmorata (type host) from Futuna Island (Wallis and Futuna Islands, Polynesia) and from A. marmorata and Anguilla sp. (cf. obscura) from Fiji Islands (Melanesia, South Pacific). The main distinguishing characteristics are the length of spicules (668-1,020 µm), situation of deirids (slightly anterior to the oesophago-intestinal junction) and the excretory pore (some distance posterior to the end of oesophagus), and the arrangement of caudal papillae in the male. It is the third known...
A new genus of parasitic copepod (Siphonostomatoida: Caligidae) from the razorback scabbardfish, Assurger anzac (Trichiuridae) off New Caledonia
Geoffrey A. Boxshall, Jean-Lou Justine
Folia Parasitologica 52 349-358 (2005) | 10.14411/fp.2005.048
A new genus and species, Avitocaligus assurgericola gen. et sp. n., of the family Caligidae is established based on an ovigerous female collected from a razorback scabbardfish, Assurger anzac (Alexander), caught off New Caledonia. This is the first record of any parasitic copepod from this fish. The new genus is placed in the Caligidae since it possesses the caligid cephalothorax incorporating the first to third pedigerous somites. It also exhibits biramous first and fourth swimming legs but lacks dorsal plates on the fourth pedigerous somite. This combination of characters serves to differentiate the new genus from existing genera. In...
Prevalence of Hemolivia mauritanica (Apicomplexa: Adeleina: Haemogregarinidae) in natural populations of tortoises of the genus Testudo in the east Mediterranean region
Pavel Široký, Martin Kamler, David Modrý
Folia Parasitologica 52 359-361 (2005) | 10.14411/fp.2005.049
Hemolivia mauritanica (Sergent et Sergent, 1904) infections were found in 14% (n = 14) of Testudo graeca Linnaeus, 1758 tortoises in Bulgaria and in 92% (n = 26) of those in Turkey. Hemolivia mauritanica-like gametocytes were found in 81% (n = 47) of wild Testudo marginata Schoepff, 1792 tortoises in Greece. Parasitaemia intensity (the percentage of infected red blood cells found in approximately 104 cells) was 0.03-22.4% in T. graeca and 0.06-12.27% in T. marginata. On the other hand, all blood samples from 40 Bulgarian, 38 Greek, and 18 Croatian specimens of Testudo hermanni Gmelin, 1789...
