FIP – The Summary from The Article from Geliebte Katze

  

 In  Geliebte Katze´s issue, June 2009, was a very interesting article about FIP – Felinous Infectious Peritonitis „Die 8 häufigsten Fragen zur FIP“ (Eight most important questions regarding FIP). As the title says, M. Streicher, the vet, explaines the most common questions about this ilness. He wrotes in this article, that the FIP- test, which is performed by a vet is a test, which detects the presence of antibodies against all coronaviruses. But it doesn´ t still exist such a test, which is able to detect the mutated coronavirus  which cause the FIP ilness. The mutated virus can be proved in transport cells – macrofagus, which the mutated virus uses for its own transport in a cat´s body.

 

About 50 % of all cats in Germany has antibodies against coronaviruses, which means, that these cats have had a previous contact with the feline coronaviruses. It isn´t right to label these cats as FIP positive ones, because only in a smal amount  of them will really appear  the FIP ilness. Some of the cats are able completely eliminate this virus – the serokonversion  appears after some time in these cats and they don´t show the antibodies against coronaviruses at all. Every cat of every age can get FIP , but the most cases occurs in younger cats. What is the reason for this is still unknown.

  

Up to one third of cats with the positive titre of antibodies excrete coraviruses with the excrements to the environment. However  the cat with FIP doesn´t excrete the mutated coronavirus into its environment, but only  a harmless virus, which is – truly to say- able to mutate. The author says: „ The transmisson of the mutated virus hasn´t  been ascertained in nature condition so far.“

  

The more is the mutated virus expanded in the host body, the higher is the risk of mutation. Cats with the positive titre antibodies against coronaviruses should be protected against stress and they should be treated with the medicaments with the imunosupressive effect   only in the most necessary cases. If the cats can go out freely, it isn´t necessary to reduce their staying out, because the possibility of infection in the outdoor environment is minimal because the outdoor cats do not go to the toilet twice on the same place. Outdoor cats bury their excrements, in which the virus is contained, as well.

 

 Coronavus is present in body fluid and it is excreted – as was said above– in excrements. From that reasons is very important to keep the cat´s toilet carefuly clear , for other cat´s not to get the infection from the excrements. It was proved, that the virus has lived in dry excrements till seven weeks.

 

 
The infection finds its was to the organism by the nose and mouth. The virus came ito thin bowel, where it multiplies and destroys some of the bowel cells. This causes diarrhoea. But if the wirus  mutate, it will able to cause FIP. The author says: „ High or rising titre of antibodies can occur in healthy cats, which will never get FIP. The higher is the antibody titre, the more of viruses is excreted in excrements. When a cat has too high titre of antibodies, it is more likely, that there is FIP present, but in about 10 % of cats vith proved FIP can´t be found  almost any antibodies."

 

 

The author says, that the efficiency of the vaccination is dicutable, but it is possible it: „ can reduce the occurrence of FIP in FcoV negativ cats.“  To be on the save side the cats inficated with FcoV and kitten under 16 weeks  shouldn´t be vaccinated  at all .
