Lymphoma is one of the most common cancers of dogs, but its cause is unknown. Its development appears to be linked to genetics as well as environmental and infectious disease factors. Previous work conducted by this research team suggests a link between lymphoma and canine hemoplasma infection. Hemoplasmas are bacteria that adhere to red blood cells and can persist in the dog's blood without causing signs of disease. This study hopes to determine whether dogs with untreated lymphoma have a higher prevalence of hemoplasma infection than dogs with untreated mast cell tumors and sarcomas. The findings may provide important information into one of the causes of lymphoma.
