Clinical signs in inoculated rabbits were limited to decreased activity and inappetence in 2 rabbits on day 4 postinoculation. Serology Initial diagnostic evaluations did not include serology because of a lack of reagents, but expression of the viral capsid within a baculovirus system enabled serologic testing by the time of depopulation.

By the late s, RHD stretched to forty countries and had become endemic in wild and feral rabbit populations in Europe, Australia, New Zealand and Cuba.

Further analysis compared nucleotide similarities of the ORF-1 polypeptide genomic sequence, excluding the capsid gene Figure 9. The amino acid sequence of MRCV polymerase was only Beginning January 1,and continuing over a 3-week period, a privately owned New Zealand White O.

Spain was the worst affected by RHD, which in turn also affected the rabbit-specialized Iberian lynx.
