Treatment of Francisella philomiragia bacteremia in a dog.

Abstract

To describe the diagnosis and successful treatment of systemic francisellosis in a dog. An 11-year-old female spayed Labrador retriever presented for progressive lethargy, hyporexia, and cough. The dog was febrile with a neutrophilia, nonregenerative anemia, thrombocytopenia, and had increased activity in serum of liver-derived enzymes. Francisella philomiragia was isolated from aerobic blood culture. The dog was treated for 6 weeks with enrofloxacin orally. Repeated aerobic blood cultures after 2 and 6 weeks of antibiotic therapy were negative. The dog was clinically normal 7 months after diagnosis with no evidence of relapse.
