Parvoviruses
Parvovirus is a very small non-enveloped DNA virus with extreme environmental stability.
It can persist in the environment for up to a year and is also very temperature-resistant.
Animals become infected oronasally with parvoviruses. First, virus replication occurs in the mucous membranes, then followed by viraemia. The lymphatic system and organs become infected.
Cat
Feline parvovirus infection – panleukopenia – is a highly contagious systemic disease of felids. The mortality rate among unvaccinated animals is over 80%.
Clinically, the disease is characterised by fever, diarrhoea, vomiting and dehydration. The blood count shows extreme leukopenia. A special case is the intrauterine infection. The mother cat is infected without showing any symptoms, but it leads to the abortion or death of the kittens. If kittens are born alive, there is often a cerebellar hypoplasia, which leads to ataxia and tremor, usually without any impairment of consciousness.
