Abstract

This report describes the clinical presentation, isolation and treatment of two dogs naturally infected with Bartonella henselae and Bartonellavinsonii subsp. berkhoffii. Chronic and progressive polyarthritis was the primary complaint for dog #1, from which B. henselae and B. vinsonii subsp. berkhoffii were cultured on three independent occasions from blood and joint fluid samples, despite administration of nearly 4 months of non-consecutive antibiotic therapy. A clinically atypical and progressively severe trauma-associated seroma was the primary complaint for dog #2, from which B. henselae and B. vinsonii subsp. berkhoffii were isolated from serum, blood and seroma fluid. Dogs can be co-infected with two Bartonella spp. and infection with these organisms should not be ruled out if specific antibodies are not detected. Specialized culture techniques should be used for isolation and to assess antibiotic efficacy.
