During the spring, summer and autumn of 1967, 1968 and 1969, 109 rabbits were collected from two localities in Northumberland. Post mortem worm counts indicated that six species of helminths were present, Trichostrongylus retortaeformis, Passalurus ambiguus, Strongyloides papillosus, Nematodirus battus, N. filicollis and Cittotaenia denticulata.T. retortaeformis was recovered from both localities, an overall infection rate of 88% being recorded.P. ambiguus and C. denticulata were found at only one of the localities which would indicate that these species have a locally discontinuous distribution and an explanation for this has been discussed.Both Nematodirus battus and N. filicollis which are normally sheep parasites were recorded for the first time from wild rabbits. The numbers of rabbits infected and size of infection were small and in consequence the rabbit can not be considered an important reservoir for these species.

ABSTRACTMountain hares were collected each month between April 1984 and March 1985 and their intestines examined for helminths. 26 rabbits were also collected between Juny and December 1984 and examined for gastro-intestinal helminths. Three nematode and two cestode species were found in the hares while only two nematode and one cestode species were found in the rabbits. Trichostronglylus retortaeformis was recorded form 88% of the 193 hares and 92% of the rabbits While comparable figures for Passalurus ambiguus were 0·5% and 54% and for Mosgovoyia pectinata 14% and 81%. Seasonal fluctuations were observed in the T. retortaeformis populations in the hare; numbers tended to be low during the winter months and high throughout the summer. Paranoplocephala wimerosa was reported for the first time from the British Isles and Trichostrongylus axei was recorded for the forst time in the mountain hare.

1. Between November 1936 and February 1937, ninety-six rabbits were examined, whilst between August 1937 and July 1938, 446 rabbits were examined for cestode parasites. The rabbits were obtained from the same area.2. The rabbits were infected with the following cestodes to the extent given, for the two periods respectively:3. Two species of the genus Hymenolepis are recorded for the first time from the rabbit, and they are briefly described.4. The seasonal fluctuations in the incidence of the above cestodes are discussed.5. The span of life of both Cittotaenia pectinata and C. denticulata is seen to be not greater than 10 months, and evidence is given to show that the intermediate host of C. denticulata is available between April and December, and that of C. pectinata from August to April.6. Evidence of host and age resistance is demonstrated in Cysticercus pisiformis.

A study was carried out in Navarra (northern Spain) on the influence of the weight, sex and reproductive status (lactant, pregnant or lactant + pregnant females and testicular weight for males) of the wild rabbit (Oryctolagus cuniculus) on two cestodes species: Andrya cuniculi and Mosgovoyia ctenoides and four intestinal nematodes: Graphidium strigosum, Trichostrongylus retortaeformis, Nematodiroides zembrae and Dermatoxys hispaniensis. A significantly higher prevalence of A. cuniculi was detected in lactant + pregnant females compared with non-breeding females. Trichostrongylus retortaeformis and N. zembrae showed a significantly higher mean intensity in lactant and lactant + pregnant females than in non-reproductive females. Trichostrongylus retortaeformis presented a higher mean intensity in females than in males, and the mean intensity of the same parasite species was significantly lower in active and inactive males compared with lactant and lactant + pregnant females. There were no significant differences between sexes in the prevalence of helminth parasites. No significant correlation was detected between host weight and the intensity (of infection) of helminths studied. No significant differences in the prevalence and mean intensity of the two cestode species were observed in the three weight categories studied (kittens, juveniles and adults). The prevalence of G. strigosum and mean intensity of T. retortaeformis were significantly higher in older heavier animals than in juveniles.

AbstractThe 18S rDNA gene of adult worms of Taenia parva found in Genetta genetta in the Iberian Peninsula and larval stages of T. pisiformis from the wild rabbit (Oryctolagus cuniculus) in Tenerife (Canary Islands) were amplified and sequenced. The sequences of the 18S rDNA gene of T. parva (1768 bp) and T. pisiformis (1760 bp) are reported for the first time (GenBank accession nos. AJ555167–AJ555168 and AJ555169–AJ555170, respectively). In 168 alignment positions microsatellites in the 18S rDNA of both taxa were detected for the first time (TGC in T. parva and TGCT in T. pisiformis) and differences in their sequences with different repetition numbers were observed. The use of nucleotide sequences of this gene in the resolution of systematic problems in cestodes is discussed with reference to the systematic status of Taenia spp. and mainly in human taeniids such as T. solium, T. saginata, and Asian human isolates of Taenia.

AbstractSamples of wild rabbits were collected each month over the six-year period 1977–82 and their intestines and abdomens examined for helminths. Three species of nematode, four of cestode and one trematode were found, Graphidium strigosum was recorded in 33% of the 786 rabbits, Trichostrongylus retortaeformis in 79%, Passalurus ambiguus in 14·2% Cittotaenia Pectinata in 37%, C. denticulata in 11%, Coenurus pisiformis in 3%, Cysticercus serialis in 0·1% and Fasciola hepatica in 0·1%. G. strigosum and P. ambiguus infections were greatest in the older heavier animals whereas juvenile rabbits had the heaviest T. retortaeformis nematode burdens. Seasonal fluctuations were observed in G. strigosum, T. retortaeformis, P. ambiguus and Cittotaenia denticulata. The sex and reproductive state of the female rabbit did not have any significant effect on either the nematode or cestode worm burdens. Myxomatosis was shown to significantly increase the worm burden of T. retortaeformis and raise that of P. ambiguus. No nematode or cestode from domesticated animals were recovered and it was concluded that since F. hepatica was found only once rabbits did not constitute a serious hazard to the farm animals grazing the area.

Tree frogs are generally regarded as arboreal frogs and those associated with water during their breeding season as aquatic/arboreal frogs. Obazuwa Wetlands and Ikpako Riparian Habitat are both located in Ovia North East and Ovia South West Local Government Areas of Edo State, Nigeria. Frogs were captured from both habitats based on Acoustic Encounter Survey (AES) and the Visual Encounter Survey (VES) techniques. A total of 169 tree frogs were examined; 103 from Obazuwa Wetlands and 66 from Ikpako Riparian Habitat. The specimens from both sites comprised 08 species. Helminth parasites belonging to four taxa were recovered, which included: Cestoda, Trematoda, Nematoda and Acanthocephala. A prevalence of 39.8% and 30.5% were recorded for Obazuwa Wetlands and Ikpako Habitat, respectively. The helminth parasites were restricted to one of both habitats except for Foleyellides sp., which was common to both sites. Some of the helminth parasites were reported for the first time in some of the hosts such as Baerietta jaegerskioeldi (in Afrixalus nigeriensis and Leptopelis spiritusnoctis), Amplicaecum africanum (in Hyperolius guttulatus, Aplectana macintoshii (in L. spiritusnoctis), Cosmocerca commutata (in A. dorsalis and L. spiritusnoctis) and Physaloptera sp. (in Hyperolius concolor Phase B and H. concolor Phase C). The occurrence of Foleyellides sp. in 6 species of tree frogs with a prevalence range of 23.1-75.1% whereas only two species have been previously reported is exceptional and of pathological concern.

1. The results of post-mortem examinations of 590 dogs and 185 cats in Shanghai are reported.2. 88% of the dogs and 97% of the cats were infected with one or more species of helminthic parasite. The cats tended to harbour a larger number of species per animal than the dogs.3. Infections with trematodes were very common, especially Clonorchis sinensis which was present in 79% of the cats.4. There was a comparatively low incidence of infection with Ancylostoma caninum.5. Prohemistomum industrium, and Echinostoma ilocanum, rare parasites of the dog, occurred.6. The following parasites are recorded in their hosts for the first time in China.1. Chlamydonema praeputialis in the dog.2. Cylicospirura subaequalis in the cat.3. Metorchis albidus as a natural infection in the dog.

The article continues the author's research on the toponymy of the North-East of the Sakha Republic, in particular the Kolyma river basin, in the aspect of the interaction of related and unrelated languages. The relevance of this work is defined in the description of local geographical terminology of Yukagir origin, as a valuable and important material in the further study of toponymy of the region. For the first time, the toponymy of the Kolyma river basin becomes the object of sampling and linguistic analysis of toponyms with local geographical terms of Yukagir origin in order to identify and analyze them linguistically. The research was carried out by comparative method, word formation, structural, lexical and semantic analysis. As a result of the research, phonetic and morphological features are revealed, the formation of local geographical terms and geographical names of Yukagir origin is outlined, and previously unrecorded semantic shifts and dialectisms are revealed. The most active in the formation of terms and toponyms is the geographical term iилil / eҕal 'coast‘, which is justified by the representation of the Yukagirs’ coast' home, housing

Excretory/secretory products released by helminth parasites have been widely studied for their diagnostic utility, immunomodulatory properties, as well as for their use as vaccines. Due to their location at the host/parasite interface, the characterization of parasite secretions is important to unravel the molecular interactions governing the relationships between helminth parasites and their hosts. In this study, the excretory/secretory products from adult worms of the trematode Fasciola hepatica (FhES) were employed in a combination of two-dimensional electrophoresis, immunoblot and mass spectrometry, to analyze the immune response elicited in sheep during the course of an experimental infection. Ten different immunogenic proteins from FhES recognized by serum samples from infected sheep at 4, 8, and/or 12 weeks post-infection were identified. Among these, different isoforms of cathepsin L and B, peroxiredoxin, calmodulin, or glutathione S-transferase were recognized from the beginning to the end of the experimental infection, suggesting their potential role as immunomodulatory antigens. Furthermore, four FhES proteins (C2H2-type domain-containing protein, ferritin, superoxide dismutase, and globin-3) were identified for the first time as non-immunogenic proteins. These results may help to further understand host/parasite relationships in fasciolosis, and to identify potential diagnostic molecules and drug target candidates of F. hepatica.
