Incidence of FIV- and FeLV-positive cats on Formentera

To obtain an epidemiological overview about occurance and spreading of FIV- and FeLV-infections on an island the plasma of 318 cats were tested for FI V-antibodies and FeLV-antigen during a castration action at Formentera (Spa in, Baleares) from January till February 1997. Additionally in some animals (n = 42) the feces were tested for presence of salmonellae. FIV-antibodies were detected in 10.4 per cent of the plasma samples. FeLV-antigen was not found in any cat. in two examined fecal samples salmonellae were diagnosed . In the FIV-test male cats were more often positive than females. Seroposi tive animals belonged in most cases to the groups of the age group between five and ten years. The most frequent findings in the FIV-positive animals were: gingivitis/stomatitis (n = 8), dental problems (n = 7), keratoconjunc tivitis (n = 5), parasitosis (n = 5), dermatitis (n = 4) or abscesses (n=3) .
