In this issue of AKC’s Canine Health Foundation newsletter, read about the Hemangiosarcoma Research Initiative, and ongoing research from the IPRL on hemangiosarcoma and Bartonella infection in dogs.

Bartonella quintana and Bartonella vinsonii subsp. vinsonii bloodstream co-infection in a girl from North Carolina, USA
Authors
Abstract
The genus Bartonella consists of globally distributed and highly diverse alpha-proteobacteria that infect a wide-range of mammals. Medically, Bartonella spp. constitute emerging, vector-borne, zoonotic, intravascular organisms that induce long-lasting bacteremia in reservoir-adapted (passive carrier of a microorganism) hosts. At times, these bacteria are accidentally transmitted by animal scratches, bites, needles sticks or vectors to animal or human hosts. We report the first documented human case of blood stream infection with Bartonella vinsoniisubsp. vinsonii in a girl from North Carolina, USA, who was co-infected with Bartonella quintana. Limitations of Bartonella spp. serology and the challenges of microbiological culture and molecular diagnostic confirmation of co-infection with more than one Bartonella spp. are discussed. When and where these infections were acquired is unknown; however, exposure to rodents, fleas and cats in the peri-equestrian environment was a suspected source for transmission of both organisms.

Highlights
A survey on Babesia infection in hunting dogs from Southern Italy was performed.
The seroprevalence for B. canis/B. vogeli was 14.0% and 0.2% for B. gibsoni.
B. canis and B. vogeli PCR prevalences were 0.15% and 1.1%, respectively.
Male gender, adult age, long hair coat and living area represented risk factors.
This canine population is mainly exposed to B. vogeli, but PCR positivity is low
