Prevalence of alternative mutations in feline infectious peritonitis virus spike protein of cats with wet and dry forms of FIP*
| Mutation | Pathologic form of FIP |
|
|---|---|---|
| Wet | Dry | |
| M1058L | 71 | 46 |
| S1060A | 5 | 1 |
| No mutation | 3 | 3 |
| Total | 79 | 50 |
*Cats were diagnosed with the dry or wet form of FIP (feline infectious peritonitis) during postmortem examination by a veterinary pathologist. The occurrence and nature of the mutation in the spike gene was established by sequencing.
