Rabbit haemorrhagic disease (RHD)
Calicivirus, a haemagglutinating RNA virus, very diffusible and stable in the environment.
- Direct: secretions and excretions.
- Indirect: fomites and vectors.
High mortality. Sudden death in its hyperacute form. Increased temperature and respiratory rate, and sometimes epistaxis and nervous disorders in the acute and subacute forms of the disease.
Hepatic necrosis, congestion and haemorrhage in multiple organs: trachea, spleen, thymus and lungs.
- Identification of the causative agent: HA, electron microscopy, sandwich ELISA, PCR and Western Blot.
- Serology: IHA and ELISA.
TREATMENT, PREVENTION AND CONTROL:
Biosecurity measures. Inactivated vaccines adjuvanted with mineral oil or aluminium hydroxide.
