Abstract

Bartonella henselae is now regarded as the etiologic agent of cat-scratch disease and a cause of bacillary angiomatosis. We examined the human immune response to Bartonella henselae infection using a newly developed enzyme immunoassay (EIA) and a Western blot procedure using outer-membrane proteins. The EIA showed 98.6% and 91.4% agreement with an indirect fluorescence method (IFA) for detection of IgM and IgG antibodies, respectively. By using Western blot analysis, reactivity to an 8-kd band showed significant correlation with positive results by the IgM IFA and EIA. In contrast, reactivity to 209-, 208.5-, 208-, 116-, and 80-kd bands was identified only in positive IgG IFA serum samples. The EIA and Western blot should be useful tests in determining the antibody response to B. henselae infection and may also be important in determining the critical epitopes in the host-parasite interaction of this organism.
