Rabbit haemorrhagic disease (RHD) is a highly infectious and fatal disease of the European rabbit (Oryctolagus cuniculus), responsible for important economic losses in the rabbit industry. The aetiological agent of the disease is a RNA virus (RHDV, Lagovirus, Caliciviridae) first detected in China in 1984. Currently RHDV is endemic in most parts of Europe, Asia and North Africa. Phylogenetic analyses of RHDV strains have identified 3 distinct groups : the classic RHDV, the variant RHDVa and RHDV2. This latter has been detected in France for the first time in 2010 in domestic and wild rabbits (Le Gall-Reculé G et al., 2013) and since then has spread throughout Europe, replacing the circulating RHDV/RHDVa strains in most european countries. RHDV2 has already been detected in Belgium in rabbitries (Marlier D et al., 2014). Here, we report for the first time the presence of RHDV2 in wild rabbits in Southern Belgium. In november 2015, the Surveillance Network of Wildlife Diseases received seven dead wild rabbits for necropsy. The discovery of 7 fresh carcasses found at the same time in a same area (Hainaut province) emphasised the infectious or intoxication hypothesis as cause of death. Postmortem examinations were performed at the Faculty of Veterinary Medicine (FVM) of the University of Liege according to a systematic protocol based on gross lesions, histopathological and targeted microbiological analysis. For necropsy, each rabbit (1) was weighted and age was determined by the presence/absence of the distal ulna protuberance, (2) stomach was investigated to exclude poison, (3) spleen was systematically driven into Yersinia CIN culture media for detection of Yersinia pseudotuberculosis, (4) lungs and livers were systematically (a) packaged into 10% formaldehyde solution for histopathology analysis (Service of Pathology, FVM) and (b) frozen at -20°C for RHDV analysis (Scanelis Laboratory,Toulouse, France) and finally (6) feces were gathered for parasitology (Service of Parasitology, FVM). At necropsy, animals (5 ...
