Helminth parasites of anurans from five locations in the savannah-mosaic and one in the transitional vegetation zone of Edo State of Nigeria were investigated. Amphibian hosts examined included Bufo regularis, B. maculatus, Dicroglossus occipitalis, Ptychadena oxyrhynchus, P. mascareniensis, P. pumilio, P. schubotzi, Xenopus muelleri, Silurana tropicalis, Rana galamensis and Leptopelis viridis. Some of the parasites infecting amphibians in the rainforest and the mangrove such as Cephalochlamys namaquensis, Mesocoelium monodi, Haematoloechus exoterorchis, Diplodiscus fischthalicus, Prosotocus exovitellosus, Ganeo africana, Rhabdias bufonis, Cosmocerca ornata, Camallanus dimitrovi, Amplicaecum africanum and Batrachocamallanus xenopodis also infected anurans of the savannah-mosaic. Others including Baerietta sp., Polystoma prudhoei, P. galamensis, Polystoma sp., Pleurogenoides tener, Haematoloechus micrurus, Ophidiscus sp., Foleyellides sp., Abbreviata sp. (larva), and larval ascaridoids were only recorded in the anurans of the savannah-mosaic zone. Since the polystomes were not recorded in the humid environment of the rainforest and the mangrove, we presume that these are preferentially parasites of anurans residing in drier environments such as prevail in the savannah. Polystoma prudhoei which was originally described from P. oxyrhynchus was recorded in B. regularis in this investigation. This represents a new host record for this parasite. The larval ascaridoid found in a number of the anuran hosts and the larvae of Abbreviata sp. found in D. occipitalis are most probably parasites of snakes and other reptiles that use amphibians as transport hosts.

The aim of this article is to give an overview of the molecular methods used for detecting helminth parasites in the environment, their advantages as well as their limitations with examples of successful applications of these methods in different helminth classes. Molecular techniques represent a wide range of sensitive diagnostic tools in parasitology. Environmental monitoring is an essential element of epidemiological studies. Many helminth parasites depend on the environment for the completion of their life cycle. The abundance of their transmissive stages determines infection risks. The application of highly specific and sensitive monitoring methods allows gathering more precise epidemiological data.

Parasite assemblages of marine fishes include an important number of larval stages of helminth parasite species that use fish as intermediate or as paratenic hosts. In previous comparative studies, larval helminths have typically been lumped with other endoparasites, and there has been therefore no study of the biodiversity and relative abundance of larval helminths and of the factors that may influence them. Here, we performed a comparative analysis across 50 species of teleost fishes from the coast of Brazil; we evaluated the effects of several host traits (body size, social behaviour, feeding habits, preference for benthic or pelagic habitats, depth range, ability to enter brackish waters and geographical distribution) on the richness and abundance of larval helminths. Among all the potential correlates of larval helminth infection investigated in this study, only two were significant when controlling for host phylogenetic influences: Host body length was correlated positively with larval helminth abundance, and fish species with a restricted geographical distribution (Atlantic coast of Brazil mainly) had greater larval helminth abundance than their relatives with a broader (whole Atlantic or cosmopolitan) distribution. Different results were obtained if no correction was made for host phylogeny: Using species values as independent statistical observations, some additional host features also appeared associated with larval helminth species richness or abundance. The results of these analyses indicate that fish phylogeny matters. Apparently, some lineages of fish harbour more larval helminths (more species and/or more individuals) than others merely because of historical reasons (i.e., ancient associations between certain parasite taxa and fish taxa) and not really because of their present ecological characteristics.

Z homogenatów Ascaris suum, Fasciola hepatica i Moniezia expansa izolowano i oczyszczano dehydrogenazę jabłczanową (E.C.1.1.1.37) zarówno rozpuszczalną, jak i mitochondrialną, stosując wielokrotne, frakcjonowane wirowanie, a następnie chromatografię kolumnową na celulozie - DE-22 DEAE. W homogenatach wszystkich trzech pasożytów stwierdzono wysoką aktywność obu postaci MDH. Maksimum aktywności w przypadku A. suum i F. hepatica wyrażało się dwoma wierzchołkami, a w przypadku M. expansa jednym dla aktywności m-MDH i dwoma wierzchołkami dla s-MDH (ryc.). Stopień czystości obydwu postaci MDH okazał się różny, zależnie od gatunku pasożyta. Autorzy, na podstawie uzyskanych wyników, rozważają szlaki przemian energetycznych w organizmach badanych gatunków pasożytów.

Twenty-nine individual amphibians (2 families, 3 species) and 12 individual reptiles (2 families, 2 species) from Douala, Cameroon (West Africa) were examined for helminths. Seventeen (59%) of the amphibians and 11 (92%) of the reptiles were found to harbor at least 1 species of helminth; 10 (34%) of the amphibians and 4 (33%) of the infected reptiles harbored multiple infections. A cestode, 6 species of nematodes, and a pentastomid were found in the herpetofauna surveyed. Nine new host and six new geographic distribution records are reported.

Eighteen species of birds of prey in the Netherlands were examined for helminth parasites: Accipitriformes - Accipiter gentilis (15 birds), A. nisus (9), Aquila pomarina (1), Buteo buteo (56), B. lagopus (4), Circaetus gallicus (2), Circus aeruginosa B (2), C. cyaneus (3), Pernis apivorus (5); Falconiformes - Falco coluinbarius (2), F. peregrinus (2), F. subbuteo (6), F. tinnunculus (31); Strigiformes — Asio flammeus (3), A. otus (35), Athene noctua (12), Strix aluco (19) and Tyto alba (15). Sixteen nematode species were found: Baruscapillaria falconis, Capillaria tenuissima, Eucoleus dispar, Pterothominx caudinflata, Cyathostoma americana, Porrocaecum angusticolle, P. depressum, P. spiralae, Physaloptera alata, P. apivori, Procyrnea leptoptera, P. seurati, P. spinosa, Spirocerca lupi, Synhimantus laticeps and Diplotriaena henryi. All species of birds were infected with nematodes with the exception of F. peregrinus. Eleven trematode species were present: Brachylaeme fuscatus, Echinostoma revolutum, Echinoparyphium agnatum, Strigea falconis, S. strigis, Parastrigea flexilis, Neodiplostomim spathoides, N. attenuation, Ichthyocotylurus platycephalus and Prosthogonimus cuneatus. Trematode infections were found in all birds except A. nisus, C. cyaneus, P. apivorus, F. columbarius, F peregrinus and A. flammeus. Centrorhynchus aluconis was the only identifiable acanthocephalan. Acanthocephalan infections were seen in A. nisus, B. buteo, C. gallicus, C. aeruginosus and S. aluco. Cestode infections were seen in 8 bird species. The cestodes could not be identified to the genus, because they were poorly preserved. Most findings are new host records for the Netherlands.

The European mink (M. lutreola) and the American mink (M. vison) are riparian mustelids inhabiting Spain. During the last few decades, M. lutreola populations have declined almost everywhere, but, since being introduced in Europe, the American mink has become wide spread there. The present study presents the first comprehensive helminthological data of both mink species in Western Europe and analyses the possible cross-transmission of some pathogenic helminths between neighbouring Spanish populations of both mustelids. One hundred and forty specimens (28 M. lutreola and 112 M. vison) from several Spanish zones were analysed. A total of thirteen helminth species were found: Metorchis bilis, Parametorchis sp., Pseudamphistomum truncatum, Euryhelmis squamula and Apophallus donicus (Trematoda), Taenia martis and T. tenuicollis (Cestoda), Aonchotheca putorii, Strongyloides mustelorum, Molineus patens, Crenosoma melesi and Aelurostrongylus pridhami (Nematoda), and Centrorhynchus ninnii (Acanthocephala). The helminth fauna of M. lutreola was qualitatively and quantitatively richer than that of M. vison. This fact was particularly evident amongst digeneans with four species (M. bilis, Parametorchis sp., P. truncatum and A. donicus) exclusively present in M. lutreola. Twenty-five M. lutreola individuals were infected with parasitic worms (89.3%). In contrast, less than half (41.1%) of the American minks analysed were infected by helminths. The helminth fauna of both European and American minks in Spain are compared with those of both mustelids in Belarus, where another important population of M. lutreola is present. Also considered are some epidemiological and pathogenic aspects of the helminth fauna of both mink species that might act as regulatory factors over the Spanish population of M. lutreola.

We present data on helminths harboured by two sympatric species of Enyalius Wagler, 1830 (E. iheringiii Boulenger, 1885 and E. perditus Jackson, 1978) from the Atlantic Rainforest of the Ilha de São Sebastião, in São Paulo state, southeastern Brazil. Six helminth species were found in the hosts: five nematodes (Cosmocerca sp., Oswaldocruzia burseyi Durette-Desset, Anjos et Vrcibradic, 2006, Oswaldocruzia fredi Durette-Desset, Anjos et Vrcibradic, 2006, Rhabdias sp., and Strongyluris oscari Travassos, 1923), and one acanthocephalan (Acanthocephalus sp.). Overall helminth prevalences were relatively high for both species [6/6 (100%) for E. iheringii and 9/14 (64%) for E. perditus]. The helminth assemblages from both host species were depauperate and dominated by generalist helminths with direct life-cycles.

A total of 51 and 21 adults of Barbary ground squirrels (Atlantoxerus getulus) were trapped during May–July 2006 from the introduced populations on Fuerteventura Island (Canary Islands) and the native populations in Morocco, respectively. One trematode, 1 cestode and 4 nematode species were recovered belonging to five families: Brachylaima sp. (Brachylaimidae), Catenotaenia chabaudi (Catenotaeniidae), Protospirura muricola (Spiruridae), Dermatoxys getula and Syphacia pallaryi (Oxyuuridae), and Trichostrongylus sp. (Trichostrongylidae). We report for the first time the presence of P. muricola, Trichostrongylus sp. and Brachylaima sp. in A. getulus. Brachylaima sp. was found in the insular population only, as a result of a diet that includes snails. The two oxyurids were found at both sites. The continental population showed higher species richness (5 vs 3 species). This is the first report of helminth parasites from A. getulus from the Canary Islands.

Bony fishes (Teleostei) play an important role in the completion of life cycles of helminth parasites in the Antarctica. These fishes may be definitive, second intermediate or paratenic hosts of the helminths. The most species-rich taxon is Digenea. Virtually all of these digeneans use teleosts as definitive hosts. Only one species, Otodistomum cestoides, occurs as the adult stage in skates (Chondrichthyes), with teleosts as its second intermediate host. Among 14 cestode species maturing in fishes only one, Parabothriocephalus johnstoni, occurs in a bony fish, Macrourus whitsoni, whereas the others are parasites of Chondrichthyes (cartilaginous fishes). Antarctic Chondrichthyes are not infected with nematode and acanthocephalan species. Specificity to the intermediate and/or paratenic hosts of the majority of Antarctic helminths is wide, whereas that for definitive hosts is often narrower, restricted to one order or sometimes even to one or two host species. Almost all of 73 helminth species maturing in Antarctic fishes are endemics. Only 4 digenean and one nematode species are cosmopolitan or bipolar.

Here, we describe a new kathlaniid nematode, Falcaustra sanjuanensis sp. nov., from the large intestine of Odontophrynus cf. barrioi (Anura: Cycloramphidae), from San Juan Province, Argentina. The new species belongs to the Falcaustra group that possesses a pseudosucker. It resembles F. andrias in the distribution pattern of caudal papillae (six precloacal, four adcloacal, 12 postcloacal, one unpaired median anterior to the cloaca) but differs from F. andrias in the following characters: the longer size of males and females (11.17–13.45 mm and 10.1–15.5 mm, respectively); the longer size and form of the gubernaculum (0.17–0.23 mm, triangular form); the arrangement of postcloacal papillae (three pairs on the ventral side, two pairs on the lateral side, one pair on the subventral side) and unpaired papilla anterior to the cloaca located on the protuberance. The species description is based on light microscopy and scanning electron microscopy (SEM). Falcaustra sanjuanensis sp. nov. represents the 12th Neotropical species assigned to the genus. Also, we added a key to Neotropical species of Falcaustra.

The helminths of two sympatric species of rodents, the striped field mouse Apodemus agrarius and the yellow-necked mouse, Apodemus flavicollis from Slovakia were studied to determine whether there are similarities in the composition of the helminth fauna of two closely related host species living in the same area. A total of twelve species of helminths were identified in these rodent populations, including Brachylaima sp. (Trematoda); Hymenolepis diminuta (Rudolphi, 1819), Mesocestoides sp. larvae, Rodentolepis fraterna (Stiles, 1906), Rodentolepis straminea (Goeze, 1782), Skrjabinotaenia lobata (Baer, 1925), Taenia taeniaeformis larvae (Batsch, 1786) (Cestoda); Aonchotheca annulosa (Dujardin, 1845), Heligmosomoides polygyrus (Dujardin, 1845), Heterakis spumosa Schneider, 1866, Mastophorus muris (Gmelin, 1790) and Syphacia stroma (Linstow, 1884) (Nematoda). In A. agrarius, H. polygyrus was the most prevalent, as well as the most abundant helminth, but R. fraterna was the species with the highest mean intensity. In contrast, S. stroma dominated the A. flavicollis helminth fauna with the highest prevalence, mean abundance and mean intensity. Both rodent populations harboured nine helminth species, although the mean individual species richness was significantly higher in A. agrarius than in A. flavicollis. The analysis of helminth diversity at both component and infracommunity levels revealed differences between the two rodent populations, which are most likely attributable to the specific host ecology.

Eleven parasite taxa were found infecting 68 Atlantic chub mackerel, Scomber colias Gmelin, 1789 from the Canary Islands, Central North Atlantic. The most abundant parasites were the gill monogenean Pseudokuhnia minor (P = 54.4%), larval anisakid nematodes (P = 11.8%) in the body cavity, a larval tetraphyllidean infecting bile ducts (P = 8.8%) and didymozoid digeneans infecting the gills (P = 7.4%). No correlation between fish length and abundance of infection with these parasites was found. Within the Atlantic, the comparison of present results with previous reports on the occurrence of parasites in this fish host, might suggest that there is more than one population unit of Atlantic chub mackerel in the Eastern Atlantic.

This paper presents the first extensive data on the helminth community of the wood mouse Apodemus sylvaticus in a coastal sand dune area in Portugal. The 557 hosts analysed in this study were trapped seasonally between autumn 2002 and summer 2005 across 6 habitat types. Twelve helminth species were detected among which, Taenia parva larvae, Angiostrongylus dujardini, Heligmosomoides polygyrus, Syphacia stroma and S. frederici constitute the component species, accounting for 98.7% of all worms. H. polygyrus was the most prevalent helminth parasite. Species richness varied according to habitat and season. The highest species richness was found in sand dunes during winter whereas the lowest was detected along lake margins also during the winter. Some differences in prevalence and mean intensity values were found in relation to year (T. parva larvae and H. polygyrus), habitat (A. dujardini), season (T. parva larvae, H. polygyrus, A. dujardini and S. stroma) and host sex (T. parva larvae and S. stroma). These differences are discussed both in view of the host’s biology and habitat characteristics.

Results of micromorphological and histological studies of larvae of Trichinella Spiralis and T. pseudospiralis, as weil as, muscles, liver and small intestine of the rat-host before and after biostimulator administration of phytohemagglutinin and phytoanthelminthic were presented. It has been established that rats with Trichinella larvae of both species developed unspecific allergic angiomyositis, hepatitis, cholangitis, and erosio-haemorrhagic enterocolitis in the host's organism on the 35th day after infection. Furthermore, processes of compensatory hypertrophy, that support the host's (rats) homeostasis, on cell and tissue levels, were observed at histodestructional and morphofunctional deficiency. lt has been revealed that phytohemagglutinin, biostimulator injected into the host's organism before infection, is of immunostimulating nature and partially destroys the larvae of Trichinella. The phytoanthelminthic produces a significant trichinellocide effect: RNA synthesis and glycogen is intensified in the organs of the treated animals, their pathomicromorphogenesis weakened, and their compensatory and regenerative processes were observed. The combined use of the phytohemagglutinin and phytoanthelminthic fails to intensify the mentioned effect.

Rodents, as mice and rats are the most common laboratory animals used in research and testing. They are seldom investigated for autochthonous ecto- and endoparasites prior their utilization in the experiments. Helminth parasites can alter the interpretation of final results. Pinworms commonly infecting laboratory rodents include mainly the mice pinworms Syphacia obvelata and Aspiculuris tetraptera, and in rats Syphacia muris. The fact that many laboratory rodent colonies were found to be parasite contaminated suggests a need for eradication and improvment of the quality of laboratory rodents. This review reports the data on the presence of helminth parasites in laboratory rodents colonies, and suggests to pay special attention on controlling the sanitary conditions of animal houses.
