| Infection par les r‚trovirus chez le chat domestique (Felis catus) et le chat sauvage (Felis silvestris) | |
| 2002 Conference Proceeding | |
We studied propagation of FeLV (Feline Leukemia Virus) and FIV (Feline Immunodeficiency Virus) retroviruses in populations of domestic cats (_Felis catus_) and wild cats (_Felis silvestris_). FeLV is one of the first causes of mortality in the domestic cat and the FIV is also pathogenic. Regarding the FIV, prevalence is identical in all population studied except for the insular population. Inside a population, the reproductive males constitute the class of major risk, the other classes being infected very little. For FeLV, prevalence varies from one population to the other and in time. The classes at risk inside a population are less marked than for the FIV. Our results suggest that FeLV could die out pontaneously in a population of wildcats except if the infection is maintained permanently by transmission between wildcats and domestic cats. On the contrary, FIV could be propagated spontaneously between wildcats, but with a low frequency. Moreover, among the sampled wildcats, FeLV infected individuals were in worse physical condition than non infected ones, which lets suppose a pathogenic capacity of the virus in the wildcat. |
