Project Summary

This study showed a statistically higher prevalence of Bartonella spp. DNA in surgical biopsy samples obtained from dogs with hemangiosarcoma (the most commonly encountered vascular neoplasm of spleen in dogs) compared to dogs with lymphoid nodular hyperplasia (the most commonly encountered non neoplastic splenic disease). These results provide preliminary evidence that bacteria of the genus Bartonella may contribute to the development of vascular tumors in dogs. One future direction the researchers hope to explore will be to test the prevalence of Bartonella spp. in other vascular tumors, particularly hemangiopericytomas. Also, in an effort to obtain additional environmental control data they are planning to test the prevalence of Bartonella spp. in the spleens of dogs euthanized at a local animal shelter. Studying additional control populations will be required to determine the medical relevance of the data generated to date and will provide information regarding the prevalence of Bartonella spp in the spleens of dogs within the general dog population.
