===Introduction===

==Introduction==

'''Feline Parvovirus''', is from the family Parvoviridae, and is also known as '''feline  infectious enteritis''' (FIE) or '''feline panleukopenia'''.  It is a non-enveloped virus, capable of persisting for long periods of time in the enviroment.

It infects the lymph nodes of the oropharynx and the nasopharynx, and the spreads to other tissues.  It infects and kills actively replicating cells.  Kittens are most susceptible, but unvaccinated older cats can also become infected.

====Pathogenesis====

==Pathogenesis==

Feline Parvovirus kills the stem cells of the villi. The villi tip cells turnover normally but are not being replaced, leading to stunted villi and malabsorption.

Animals who have contracted the virus usually die despite treatment, due to the extensive dehydration.

====Epidemiology====

==Epidemiology==

Infection may be  via '''direct contact''' or by '''fomites'''. Subclinical infection may also occur.

Modified live and inactivated virus vaccines are avaliable, with boosters every 1-2 years required.

One should also try to prevent exposure to kittens with feline panleukopenia.

Since the introduction of a vaccine, this disease is now relatively uncommonly seen.

Over the last 10/15 years this has been seen primarily in the cat, but it is now also seen [[Canine Parvovirus|in the dog]].

===Pathology===

==Gross Pathology==

 

====Gross====

The virus targets crypt cells and lymphoid areas,causing [[:Category:Enteritis, Villus Atrophy|villus atrophy]].  In the cat, the intestine becomes thickened, turgid and swollen, with a pale, dull and mottled appearance.

Lower down in the gut, enteritis is apparent. In the cat this is fibrinous enteritis, and in the dog it is haemorrhagic.

====Histological====  

==Histological Pathology==  

The crypt lining cells undergo complete necrosis, but very little inflammation is seen.
