SEROPREVALENCE OF BARTONELLA-HENSELAE INFECTION AND CORRELATION WITH DISEASE STATUS IN CATS IN SWITZERLAND

The prevalence of infection with Bartonella henselae was investigated in cats from different areas of Switzerland, Serum samples of 728 cats were examined for antibodies to B, henselae by immunofluorescent anti body testing, and the results were analyzed with a view to a possible correlation between a positive titer and signalment, clinical signs, i nfection with feline leukemia virus (FeLV), feline immunodeficiency vi rus (FIV), feline coronavirus (FCoV), or feline spumavirus (FeSFV), an d the living environments of the cats, The seroprevalence in all cats was 8.3%, No significantly different prevalence was found in sick vers us healthy cats (9.2 versus 7.2%); however, in sick cats seropositive for B, henselae, there was an increased frequency of stomatitis and a variety of diseases of the kidneys and the urinary tract, There was an increased prevalence of B, henselae in cats positive for FCoV (P = 0. 0185) or FeSFV (P = 0.0235) and no statistically significant increased prevalence in cats infected with FeLV or FIV, There was no correlatio n between a positive titer and sex or breed, The same prevalence of B, henselae antibodies was found in cats with and without access to the outdoors and in cats from single-and multicat households. The seroprev alence was increased in cats living south of the Alps (12.1%); however , this difference was not significant (P = 0.0616).
