| Abstract: | A polymerase chain reaction (PCR) originally developed for detection of Haemobartonella felis in cats was successfully used for detection of H canis in an 8-year-old spayed Great Dane. The dog had been splenectomized and was undergoing immunosuppressive chemotherapy at the time of diagnosis. Sequence analysis of the 16S ribosomal RNA gene revealed that the Haemobartonella spp infecting this dog was 97% homologous to the sequence previously reported for the Ohio strain of H felis. Clinical and hematologic abnormalities as well as identification of the organisms by use of light and electron microscopy supported the diagnosis of H canis. The PCR assay used for detection of H felis may be useful for the detection of H canis in dogs prior to blood donation, splenectomy, or treatment with immunosuppressive drugs. |
