Epidemiology of Coxiella burnetii Infection in Dogs and Cats in Shizuoka Prefecture

Abstract

Eight (9.9%) of 81 and 7 (6.7%) of 105 sera from sheltered dogs and cats, respectively, were shown to have antibodies to Coxiella burnetii Nine Mile II by indirect immunofluorescence (IF). All the 8 sera from dogs and cats reared by infected human patients were positive for the antibody. C. burnetii was isolated from all the antibody-positive sera of dogs and cats reared by human patients as well as from 2 of 7 antibody-positive sera or spleens of sheltered cats by inoculation into cyclophosphamide-treated mice.
