title: Detection of Bartonella henselae in the blood of 2 adult horses.
abstract: BACKGROUND
  Bartonella spp. are emerging zoonotic agents that have been found in a wide variety of domestic animals and wildlife and cause a number of clinical syndromes. Bartonella sp. infection has been identified in a growing number of animal species, including cats, rodents, porpoises, and canids, but has not been reported in horses.
  
  
  OBJECTIVE
  To document the presence of Bartonella sp. in the blood of horses.
  
  
  METHODS
  One horse with chronic arthropathy and 1 horse with presumptive vasculitis.
  
  
  METHODS
  Blood samples were tested for the presence of Bartonella sp. by a combination of multiplex real-time polymerase chain reaction and enrichment culture technique.
  
  
  RESULTS
  Bartonella henselae was isolated or detected in the blood of both horses.
  
  
  CONCLUSIONS
  Bartonella henselae infection should be investigated as the cause of disease in horses.
