A seroepidemiological study on Ehrlichia canis infection was performed in 16 dogs in a kennel in the region of Plovdiv in Bulgaria. For this purpose, anti-E. canis antibodies were detected by the indirect immunofluorescence antibody test. The results showed that 75% of the dogs examined were positive to E. canis. The antibody titres 1:100, 1:200 and 1:400 were detected.
