Note: Passive Antibody to Bartonella henselae Protects against Clinical Disease following Homologous Challenge but Does Not Prevent Bacteremia in Cats

摘要

We challenged cats transfused with anti-Bartonella serum and kittens born to antibody-positive queens with Bartonella henselae to determine the contribution of antibodies to the control of B. henselae in cats. In both experiments, antibody-positive cats were protected from clinical disease but passive antibody to the homologous strain of B. henselae did not prevent bacteremia.
