Folia Parasitologica 56[3] 173-179 (2009) | DOI: 10.14411/fp.2009.021  

Blood films were examined from 154 wild and captive tortoises from four provinces of South Africa, including Gauteng, Kwazulu-Natal, North West and Western Cape. The five species of chelonians studied were Chersina angulata (Schweigger), Kinixys belliana belliana (Gray), K. lobatsiana Power, K. natalensis Hewitt, and Stigmochelys pardalis (Bell). Two species of haemogregarines, previously reported from Mozambique, were identified in blood films, namely Haemogregarina fitzsimonsi Dias, 1953 and Haemogregarina parvula Dias, 1953. Additional stages of development (trophozoites and probable meronts, merozoites...

The genus Hyalomma Koch, 1844. X. Redescription of all parasitic stages of H. (Euhyalomma) scupense Schulze, 1919 (= H. detritum Schulze) (Acari: Ixodidae) and notes on its biology

Dmitry A. Apanaskevich, Natalia A. Filippova, Ivan G. Horak

Folia Parasitologica 57[1] 69-78 (2010) | DOI: 10.14411/fp.2010.009  

Taxonomic uncertainty as to the identities of Hyalomma (Euhyalomma) scupense Schulze, 1919 and Hyalomma detritum Schulze, 1919 has existed for nearly 85 years. The chief criterion used to consider these taxa as separate species has been an ecological feature, namely that H. scupense is a one-host tick while H. detritum is a two-host species. Morphologically they are identical. To date no comprehensive taxonomic study has been done on all parasitic stages of the two species. Here the decision to grant priority status to H. scupense and to synonymise H. detritum with H. scupense is defended....

We assessed IgG antibody to Toxoplasma gondii in 300 inpatients with schizophrenia (SG), 150 outpatients with anxiety and depressive disorders (PCG), and 150 healthy blood donors (HCG). Seropositivity rates were 60.7% for SG, 36.7% for PCG, and 45.3% for HCG (p<0.001). The seropositivity rate for anti-Toxoplasma IgG antibodies in SG was significantly higher that in PCG (X²=23.11, OR=2.66, p=0.001) and HCG (X²=9.52, OR=1.86, p=0.002). Among SG, 85% of those who reported close cat contact had IgG antibodies to T. gondii. Close cat contacts were reported by 59% of SG, 6% of PCG, and 9% of HCG (p<0.001)....

Toxoplasma gondii strain-dependent effects on mouse behaviour

Geetha Kannan, Krisztina Moldovan, Jian-Chun Xiao, Robert H. Yolken, Lorraine Jones-Brando, Mikhail V. Pletnikov

Folia Parasitologica 57[2] 151-155 (2010) | DOI: 10.14411/fp.2010.019  

Toxoplasma gondii reportedly manipulates rodent behaviour to increase transmission to its definitive feline host. We compared the effects of mouse infection by two Type II strains of T. gondii, Prugniaud (PRU) and ME49, on attraction to cat odour, locomotor activity, anxiety, sensorimotor gating, and spatial working and recognition memory 2 months post-infection (mpi). Attraction to cat odour was reassessed 7 mpi. At 2 mpi, mice infected with either strain exhibited significantly more attraction to cat odour than uninfected animals did, but only PRU-infected mice exhibited this behaviour 7 mpi. PRU-infected mice had significantly greater...

Folia Parasitologica 57[4] 280-288 (2010) | DOI: 10.14411/fp.2010.034  

Ascaridoid nematodes referable to Brevimulticaecum heterotis (Petter, Vassiliadès et Marchand, 1979) Khalil, 1984 were recorded from the intestine of the African bonytongue, Heterotis niloticus (Cuvier) (Arapaimidae, Osteoglossiformes), from the Mare Simenti in the Niokolo Koba National Park, East Senegal and from Kosti, Sudan. Their examination using light microscopy and for the first time both environmental scanning electron microscopy and scanning electron microscopy revealed some previously unreported morphological features and made possible a detailed redescription of this species. The most important finding is the presence...

Simon Jones, Ivan Fiala, Gina Prosperi-Porta, Marcia House, Sonia Mumford

Folia Parasitologica 58[2] 87-94 (2011) | DOI: 10.14411/fp.2011.009  

A new species of sphaerosporid myxosporean, Sphaerospora elwhaiensis sp. n., is described from kidney of non-anadromous sockeye salmon (kokanee) Oncorhynchus nerka (Walbaum) from Lake Sutherland in the northern Olympic Peninsula, Washington, USA. Infection with the parasite was detected in 45% of 177 kokanee examined over 5 years. While conforming to the morphological criteria by which members of the genus are defined, the parasite is distinguished from congeners in salmonids of western North America by a unique combination of valvular sculpting of the myxospore, the relatively large size of the myxospore and monosporous development within...

A new genus and two new species of Anteroporidae (Cestoda: Lecanicephalidea) from the darkspotted numbfish, Narcine maculata (Torpediniformes: Narcinidae), off Malaysian Borneo

Kirsten Jensen, Pavel Nikolov, Janine N. Caira

Folia Parasitologica 58[2] 95-107 (2011) | DOI: 10.14411/fp.2011.010  

The cestode fauna of the darkspotted numbfish, Narcine maculata (Shaw) (Torpediniformes: Narcinidae), from Malaysian Borneo was examined for the first time. This work resulted in the discovery of a new genus and two new species of Anteroporidae (Lecanicephalidea). Sesquipedalapex comicus gen. n., sp. n. was erected on the basis of the peculiarities of its scolex, in particular its possession of an extremely long apical modification of the scolex proper, which readily distinguishes it from the other genus in the family. The genus is also distinct in its possession of acetabula that are in the form of suckers, rather than bothridiate in...

Natural and anthropogenic factors shape metazoan parasite community structure in mummichog (Fundulus heteroclitus) from two estuaries in New Brunswick, Canada

Christopher A. Blanar, David J. Marcogliese, Catherine M. Couillard

Folia Parasitologica 58[3] 240-248 (2011)  

Previously published multidisciplinary studies in the Miramichi and Bouctouche rivers (New Brunswick, Canada) noted significant changes in fish health parameters, including elevated tissue levels of organic contaminants and a wide range of physiological disturbances, in mummichog Fundulus heteroclitus (L.) from a site on the Miramichi River that received bleached kraft pulpmill and municipal effluent. The present study reports differences in the abundance of individual parasite species, as well as parasite infracommunity and component community composition, in mummichog from both rivers. These differences were evaluated in relation to host (size,...

Rhaphidotrema kiatkiongi, a new genus and species of blood fluke (Digenea: Aporocotylidae) from Arothron hispidus (Osteichthyes: Tetraodontidae) from the Great Barrier Reef, Australia

Russell Q.Y. Yong, Thomas H. Cribb

Folia Parasitologica 58[4] 273-277 (2011) | DOI: 10.14411/fp.2011.026  

A new genus of fish blood flukes (Aporocotylidae Odhner, 1912) is proposed for a species found on reefs surrounding Lizard Island on the northern Great Barrier Reef. Rhaphidotrema kiatkiongi gen. et sp. n. was recovered from the heart of the stars-and-stripes pufferfish, Arothron hispidus (L.) (Tetraodontidae). Rhaphidotrema kiatkiongi is notable as the first digenean reported to possess a penis stylet. It also differs from all other aporocotylid flukes in having a combination of 18-19 testes in a group at the ends of the intestinal caeca, a broad lanceolate body shape with a dextrally-directed posterior bend at the level of the...

Ying Shan, Jun Liu, Yong-Jun Jiang, Hong Shang, Dong Jiang, Ya-Ming Cao

Folia Parasitologica 59[3] 153-161 (2012)  

In cases of human malaria, children suffer very high rates of morbidity and mortality. To analyze the mechanisms involved in age-dependent protection against malaria, we investigated the characterization of immune responses to Plasmodium yoelii 17XNL (P.y 17XNL) in young (3 weeks) and middle-aged (8 months) C57BL/6 mice. In this study, we found that 100% of young mice succumbed to P.y 17XNL infection with higher parasitemia, while middle-aged mice were able to clear blood parasites and no mortality was observed. These observations suggested that the young C57BL/6 mice were susceptible to P.y 17XNL infection, whereas the middle-aged mice were...

Folia Parasitologica 59[4] 241-248 (2012) | DOI: 10.14411/fp.2012.033  

The genus Hepatozoon Miller, 1908 (Apicomplexa: Adeleorina) is composed of intracellular haemogregarine parasites that are widely distributed among all tetrapod groups. The present study combines microscopic and molecular data on haemogregarine parasites from lizards in the western Mediterranean. We screened tissue samples and examined blood smears for the presence of species of Hepatozoon from four lizards, namely Algyroides marchi Valverde, endemic to Southeast Spain, Podarcis bocagei Seoane from Spain and Portugal, P. hispanica Steindachner from Spain, and P. lilfordi Günther from Cabrera, Balearic Islands...

A new species of Australotaenia (Cestoda: Proteocephalidea) from a snake in Cambodia: host switching or postcyclic parasitism in a distant region?

Alainde Chambrier, Tomáš Scholz

Folia Parasitologica 59[4] 279-286 (2012) | DOI: 10.14411/fp.2012.039  

Australotaenia de Chambrier et de Chambrier, 2010 has been proposed to accommodate two species of proteocephalidean cestodes from hylid frogs (Litoria spp.) in Australia. Recently, apparently congeneric cestode, for which the name A. bunthangi sp. n. is proposed, was found in the homalopsid snake Enhydris enhydris (Schneider) (Serpentes: Homalopsidae) from South-East Asia (Cambodia). This finding indicates a much wider range of definitive hosts of species of this genus, i.e. amphibians and reptiles, which is exceptional among proteocephalideans. Postcyclic parasitism, i.e. predation of the definitive host infected with...

Cardicola langeli sp. n. (Digenea: Aporocotylidae) from heart of sheepshead, Archosargus probatocephalus (Actinopterygii: Sparidae) in the Gulf of Mexico, with an updated list of hosts, infection sites and localities for Cardicola spp.

Four new species of the genus Hatschekia Poche, 1902 (Copepoda: Siphonostomatoida: Hatschekiidae) are described based on female specimens collected from pufferfishes (Tetraodontiformes: Tetraodontidae) caught in coastal waters off the Ryukyu Islands, Japan: H. longiabdominalis sp. n. on Arothron hispidus (Linnaeus), H. geniculata sp. n. on A. hispidus (type host) and A. stellatus (Bloch et Schneider), H. ellipsocorpa sp. n. on A. mappa (Lesson), and H. boonah sp. n. on A. nigropunctatus (Bloch et Schneider) (type host) and A. meleagris (Schneider). Hatschekia longiabdominalis...

A new genus and species of the Monticelliinae (Eucestoda: Proteocephalidea), a parasite of Pseudoplatystoma fasciatum (Pisces: Siluriformes) from the Paraná River basin (Argentina), with comments on microtriches of proteocephalideans

Nathalia J. Arredondo, Alain de Chambrier, Alicia A. Gil de Pertierra

Folia Parasitologica 60[3] 248-256 (2013) | DOI: 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...

Uncinaria sanguinis sp. n. (Nematoda: Ancylostomatidae) from the endangered Australian sea lion, Neophoca cinerea (Carnivora: Otariidae)

Alan D. Marcus, Damien P. Higgins, Jan Šlapeta, Rachael Gray

Folia Parasitologica 61[3] 255-265 (2014) | DOI: 10.14411/fp.2014.037  

This study investigates the identity of hookworms parasitising the Australian sea lion, Neophoca cinerea (Péron), from three colonies in South Australia, Australia. The Australian sea lion is at risk of extinction because its population is small and genetically fragmented. Using morphological and molecular techniques, we describe a single novel species, Uncinaria sanguinis sp. n. (Nematoda: Ancylostomatidae). The new species is most similar to hookworms also parasitic in otariid hosts, Uncinaria lucasi Stiles, 1901 and Uncinaria hamiltoni Baylis, 1933. Comparative morphometrics offered limited utility for distinguishing...

Two new and two redescribed species of Anonchotaenia (Cestoda: Paruterinidae) from South American birds

Anna J. Phillips, Boyko B. Georgiev, Andrea Waeschenbach, Jean Mariaux

Folia Parasitologica 61[5] 441-461 (2014) | DOI: 10.14411/fp.2014.058  

Morphological examination of novel specimens of paruterinid cestodes from passerine birds from Brazil and Chile and of museum specimens from Paraguay revealed two new species: Anonchotaenia prolixa sp. n. from Elaenia albiceps chilensis Hellmayr from Chile, and Anonchotaenia vaslata sp. n. from Tyrannus melancholicus (Vieillot) (type host) and Myiodynastes maculatus (Statius Muller) from Paraguay. The generic diagnosis of Anonchotaenia Conn, 1900 is amended, prompted by the presence of the armed cirrus and the elongated cirrus sac of A. prolixa. Two species were redescribed: Anonchotaenia...

Folia Parasitologica 62[1] (2015) | DOI: 10.14411/fp.2015.042  

Faecal samples from 162 wild animals were collected from 32 distinct sites of Łęczyńsko-Włodawskie Lakeland (eastern Poland). The presence of Giardia duodenalis (Stiles, 1902) was assessed by a Direct Fluorescence Assay (DFA) and by Polymerase Chain Reaction (PCR) and sequencing of a fragment of the beta-giardin gene. DFA showed the presence of cysts of G. duodenalis in 12 of 162 faecal samples (7%), namely in four wild boars (15%), four foxes (19%), two roe deer (4%), and two wolves (29%). PCR identified 34 of the 162 (21%) samples as positive, including 11 wild boars (41%), five red deer (18%), 11 roe deer (23%), four moose (17%), two...
