Detection of Antibody toEhrlichia canisin Dogs

Abstract

The prevalence of antibody toEhrlichia caniswas investigated in dogs in Kyushu Island, Japan by indirect fluorescent antibody (IFA) test using an Oklahoma isolate grown on DH82 cells as the antigen. Of 622 dogs without any noticeable clinical signs, 12 (1.9%) showed the IFA titers of 1: 20 to 1: 320. Of four patient dogs with fever, anorexia, weight loss, extreme weakness, epistaxis or pancytopenia, one showed the IFA titer of 1: 80.
