Upon accession on the 22nd of May 2018 into the Marine centre (day 0), blood samples were collected. Results from standard haematological and clinical biochemical analyses on these samples were all within normal ranges, without any indication of immunosuppression, anaemia, or inflammation (see Additional file 1 for the results of all blood analyses including reference intervals as previously published [27]). The animal was in a normal healthy condition without skin lesions upon accession.
