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.

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.

First Time

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.

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.

The level of genetic diversity of mountain hare Lepus timidus was assessed in Karelia for the first time. A significant remainder was revealed after substraction of Но value from Не, which value indicates the predominant selection of homozygotes rather than heterozygotes and the occurrence of inbreeding in the groups under study. The Fst value equal to 0.133 was calculated for the animals from different regions and indicates their genetic differentiation, which allows distinguishing subpopulation groups in mountain hare population.

AbstractTwenty species of helminth parasites were identified from fox, wolf, jackal and wild cat material collected in Greece. Of the 314 foxes (Vulpes vulpes) examined, 18 helminth species were recovered comprising one trematode, eight cestodes, seven nematodes and two acanthocephalans, with the cestode species Mesocestoides sp. (73.2%), Joyeuxiella echinorhynchoides (24.5%) and the nematode species Uncinaria stenocephala (43.9%), and Toxocara canis (28.6%) being the most prevalent. Five cestode and three nematode species were reported from six wolves (Canis lupus), together with one trematode, three cestode and four nematode species from five jackals (Canis aureus) and two cestode and three nematode species from four wild cats (Felis silvestris) examined. The species J. echinorhynchoides, Taenia crassiceps and Onicola canisand the genera Spirometra, Rictularia and Pachysentis are reported here for the first time in Greece. The results are discussed in the light of the feeding characteristics of wild carnivores in rural areas of Greece.

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.
