“…The higher mean intensity of G. strigosum in 2003 is in accordance with the concept of parasite load increasing with age (see Wilson et al , 2001), as also verified for this nematode by Boag & Kolb (1989) in Scotland, and Dunsmore (1966) in Australia. It is thereby suggested that either the wild rabbit does not acquire resistance to infection with increasing age, as also suggested by Molina et al (1999), or that G. strigosum does not respond to host immunity (Lello et al , 2004). Apart from host density and age, according to Dunsmore (1966) and Allan et al (1999), suitable conditions of humidity and temperature could favour these higher values of G. strigosum .…”

“…In the Iberian Peninsula, the interpretation of wild rabbit helmithfaunal data in view of ecological and host parameters has been attempted in studies referring to several Spanish regions (e.g. Blasco et al , 1996; Molina et al , 1999), whereas the scarce studies on the helminth parasites of Portuguese wild rabbits are merely descriptive (Carvalho-Varela, 1967; Maia et al , 1994).…”

The present study focuses on the helminth parasite community of the wild rabbit in a sand dune area in Portugal over a 5-year period. The influence of host sex and year on the composition of the helminth community is assessed, along with the potential effect of the detected helminths on host body condition. The basic structure of the helminth community comprises Mosgovoyia ctenoides, Graphidium strigosum, Trichostrongylus retortaeformis, Nematodiroides zembrae and Passalurus ambiguus. Mean intensities of G. strigosum varied between years. General G. strigosum intensities were also found to vary according to both year and host sex, but not according to the interaction of both factors. When assessing the effect of helminths on rabbit body condition (expressed by the kidney fat index), higher burdens of M. ctenoides, a cestode that presents a relatively large body mass, were found to induce a reduction in rabbit condition.

“…Rabbits in Tenerife have fewer species of parasites than rabbits found in the Iberian Peninsula from where the wild rabbit stocks of the Canary Islands originated. Sixteen helminth species have been reported in the Iberian wild rabbit (Cordero del Campillo et al, 1994;Blasco et al, 1996;Molina et al, 1998Molina et al, , 1999) and this appears to be the richest helminth fauna found in this host in Europe (Blasco et al, 1996). Only a small number of these species were introduced in Tenerife despite the similarities in the flora and fauna of several island zones within the Mediterranean region (Juan et al, 2000).…”

Parasitic helminths of the wild rabbit, Oryctolagus cuniculus, in different bioclimatic zones in Tenerife, Canary Islands

Faunistic and ecological analyses of the wild rabbit helminth fauna were undertaken in Tenerife island (Canary Islands). Rabbits were collected between 1998 and 2000 in seven bioclimatic zones in Tenerife selected by orientation and altitude. Five parasite species were identified, three cestodes (Taenia pisiformis (larvae), Andrya cuniculi and Mosgovoyia ctenoides) and two nematodes (Trichostrongylus retortaeformis and Passalurus ambiguus). Taenia pisiformis presented an irregular distribution with significant differences in prevalences between the zones. Andrya cuniculi was only found in two zones and there were no significant differences in prevalence values. Mosgovoyia ctenoides presented a wide distribution with significant prevalences, which were higher in northern compared to southern zones. Trichostrongylus retortaeformis was absent in the low southern zones of the island. Passalurus ambiguus was found in all zones with no significant difference in the prevalence of infection. The differences in prevalences are likely to be explained by abiotic factors in the case of T. retortaeformis, and by the absence of definitive and intermediate hosts in the case of T. pisiformis and A. cuniculi, respectively. All parasite species in Tenerife are common helminths in the Iberian Peninsula, from which their rabbit hosts originated. No significant differences were recorded in the mean intensities of infection of any of the parasite species identified.

“…This prevalence in the infestation of females could be due to the weakening of the organism as a result of the physiological stress associated with the pregnancies and births. Confirmation of this hypothesis is found in the work of Molina et al (1999) who have established a significantly higher prevalence of the tapeworm Andrya cuniculi in lactating and pregnant wild rabbits compared with non-breeding females.…”

During the period 2009–2016, seven hundred and ninety lungs from brown hares (Lepus europeus L.) from different regions of Bulgaria were investigated for presence of parasites. The results showed that 11.14% of the lungs were parasitised. Four parasite species were established: two nematodes – Protostrongylus tauricus and P. cuniculorum (recorded for the first time as a part of the helminth fauna of the country), one cestod – larval form of Taenia pisiformis – Cysticercus pisiformis and one arthropod – larval form of Linguatula serrata – Pentastomum denticulatum. The infected hares came mainly of the south parts of the country. The highest prevalence of infection was observed in the South West region, followed by the South Central and South East regions. From the northern parts of the country parasites were established only in the northeastern districts near to Black Sea and Danube River. The ratio of prevalence of infection in female vs male animals was 1.4:1. Infections with protostrongylids and cysticerci were established at the earliest in hares at the age of 4–6 months and with P. denticulatum: in hares between 7 and 9 months. The prevalence of infection varied in animals from the different age groups. The highest prevalence of infection was observed in the young (4–6 months) and adult hares (over 3 years of age).
