Abstract
OBJECTIVES
To prospectively describe the clinical and biological impact of vector-borne haemopathogens in anaemic dogs in France and occurrence of haemolysis.
MATERIALS AND METHODS
This prospective descriptive cohort study includes 134 client-owned dogs that were anaemic on admission at the Veterinary Teaching Hospital of VetAgro Sup, Lyon, France. They underwent comprehensive screening with PCR to detect a panel of vector-borne haemopathogens, SNAP Leishmania and SNAP 4Dx Plus (IDEXX).
RESULTS
Vector-borne haemopathogen-associated anaemia accounted for 17·2% (23/134) of anaemic cases. PCR for Babesia species, Mycoplasma species, Anaplasma platys or Ehrlichia canis and positive serology for Leishmania species, occurred in 11/23, 10/23, 2/23, 1/23 and 1/23 cases, respectively. Two dogs had positive PCR for both Babesia and Mycoplasma species. All dogs infected with Mycoplasma species alone had neoplastic disease. Vector-borne haemopathogens were the second most common cause of haemolysis (7/23, 30·4%). In the multivariable regression model, males were overrepresented ( OR : 2·82, P=0·03) and haemolysis ( OR : 3·31, P=0·01) was more frequent in dogs with vector-born haemopathogen-associated anaemia.
CLINICAL SIGNIFICANCE
Vector-borne haemopathogens are a common cause of anaemia in this geographical region.
