Clinical Signs

Depending on the Bartonella spp., a wide range of clinical and pathologic abnormalities can develop in dogs similar to those observed in humans: clinical manifestation of Bartonella infection can range from asymptomatic infection, to severe disease and sudden death. There is also a large variation in duration of illness.

In dogs, B. vinsonii subsp. berkhoffii has been identified as an important cause of endocarditis and has been associated with cardiac arrhythmias, myocarditis, granulomatous rhinitis, anterior uveitis and chorioretinitis.

Clinical signs related to Bartonella infection in dogs:

  • Endocarditis
  • Myocarditis
  • Anaemia
  • Hepatitis
  • Polyarthritis
  • Uveitis, choroiditis
  • Weight loss
  • Epistaxis
