Recent evidence supports a causal relationship between Bartonella
(Rochalimaea) henselae, cat-scratch disease (CSD), and bacillary
angiomatosis. Cats appear to be the primary reservoir. Blood from 19 cats
owned by 14 patients diagnosed with CSD was cultured. Blood samples from
cats owned by veterinary students (n = 25) having no association with CSD
or bacillary angiomatosis were cultured as controls. Eighty-nine percent
(17 of 19) of cats associated with CSD patients and 28% (7 of 25) of
controls were bacteremic with Bartonella species (chi-square = 16.47; P
< 0.001). Twenty-three isolates were characterized as B. henselae, while
one isolate from the cat of a CSD patient appeared to be a new Bartonella
species. Thirteen cats remained culture positive during the ensuing
12-month period. Our results support the conclusion that B. henselae is the
predominant species involved in CSD and is transmitted by cats. The
incidence of Bartonella bacteremia in control cats suggests that B.
henselae bacteremia is prevalent among the domestic cat population in the
United States.
