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.

Wildlife plays an important role in the epidemiological cycle of Toxoplasma gondii. The European wild rabbit (Oryctolagus cuniculus) can be a source of infection to wild and domestic hosts, including human beings. Additionally, as an herbivorous animal, the European wild rabbit may also be a sentinel of environmental contamination with T. gondii and, consequently, an indicator of the potential transmission of this parasite. The purpose of the present work was to detect T. gondii DNA in European wild rabbit from central Portugal, as well as the possible implications for public health. Heart and diaphragm samples were obtained from 28 rabbits hunted in central Portugal. Nested PCR separately amplified the 5′ and 3′ ends of the surface antigen 2 (SAG2) gene. T. gondii DNA was detected in 19 out of the 28 sampled animals, resulting in a prevalence of 67.9%. These results show that T. gondii infection occurs in European wild rabbit and therefore may pose a potential risk for humans if consumed as raw or undercooked meat. Measures should be taken in order to prevent infection by this zoonotic parasite and for the conservation of wildlife. To the best of our knowledge, this is the first study performed by means of PCR on T. gondii in European wild rabbit meat samples.

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.

The European wild rabbit (Oryctolagus cuniculus) has become the major agricultural and environmental pest species in Australia. Current methods of rabbit control are lethal procedures which are increasingly questioned for their overall efficiency, applicability, specificity, cost and humaneness. New initiatives are required. One such initiative is virus-vectored immunocontraception. In this approach, the lagomorph-specific myxoma virus will be genetically engineered to include genes encoding components of rabbit gametes which can induce an immune response that causes infertility. Central to such a strategy is the ability to identify antigens capable of inducing an immunocontraceptive response. A strategy for identifying such antigens has been described previously. A case study of one sperm antigen, PH-20, is reported here. The issues involved in developing this antigen to the stage where it could be considered as a candidate for insertion into a recombinant myxoma virus with the ultimate goal of testing for immunocontraceptive efficacy are discussed. Techniques for inserting genes into myxoma virus have been described previously. The knowledge gained from research with this particular antigen are broadly applicable to other antigens used for both immunocontraceptive vaccines in general and, specifically, for virus-vectored immunocontraception.
