SUMMARYIn wild rabbits (Oryctolagus cuniculus) on an estate in Perthshire, central Scotland, the seroprevalence ofToxoplasma gondiiwas 18/548 (3·3%). The wild rabbit could be aT. gondiireservoir and it has potential value as a sentinel ofT. gondiiin environmental substrates.Toxoplasma gondiiwas associated with female sex (P< 0·001) and with relatively heavy infections byEimeria stiedae(P= 0·036). It was not associated with the intensity of coccidial oocysts, the severity of myxomatosis caused by the virusMyxomatosis cuniculi, the intensity of roundworm eggs, the year or season, rabbit age or distance from farm buildings. Coinfections could have been affected by gestational down regulation of type 1 T helper cells. A sudden influx or release ofT. gondiioocysts might have occurred. This is the first report ofT. gondiiin any wild herbivore in Scotland and also the first report of lapineT. gondiias a coinfection withE. stiedae, M. cuniculiand helminths.

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.
