During the past 4 years, with support from the American Kennel Club Canine Health Foundation, our research group has documented that current serological assays lack sensitivity, specificity, or both for assessing exposure to Bartonella spp. in dogs. Thus, when used diagnostically for an individual dog or epidemiologically for the detection of Bartonella spp. antibodies in dog populations, results would be inaccurate due to false-negative (poor sensitivity) or false positive (poor specificity) IFA testing.

Research Update CHF 02528 EY3: Developing a Next Generation Sequencing Diagnostic Platform for Tick-Borne Diseases
Diagnostic tests based on the detection of DNA from harmful organisms in clinical samples have revolutionized veterinary medicine in the last decades. Currently, diagnostic panels for several vectorborne diseases (VBDs) are available through universities and private labs in the USA and abroad.

Research Update CHF 02553 EY2: Targeted Next Generation Sequencing Panel for Comprehensive Testing of Vector-borne Pathogens
We proposed to develop a comprehensive method for detection of infectious diseases of dogs, taking the guesswork out of determining which tests to use for diagnosis, and potentially improving disease surveillance because of the comprehensive nature of the test. This method takes advantage of the amount of data that can be generated with next-generation sequencing (NGS) but will be performed in a way to keep costs down and maintain adequate turn-around time for diagnostic use.

Research Update CHF 02528 MY2: Developing a Next Generation Sequencing Diagnostic Platform for Tick-Borne Diseases
Despite the wide availability of tick-borne disease panels at laboratories in the USA and abroad, most results from sick dogs are negative, which frustrates veterinarians and dog owners trying to reach a definitive diagnosis.

Research Update Mid-year 3 CHF 02519: Prevalence of Bartonella spp. Infection in Dogs with Cardiac and Splenic Hemangiosarcomas Within and Between Geographic Locations
We are on track to accomplish all of our aims for this study. We were able to obtain the initial set of samples on April 26, 2018 so we had a short delay in starting this study. We have now completed all Year I study aims, with the exception of immunohistochemistry and FISH localization of Bartonella organisms within various cell types. An unanticipated complication arose that the mouse monoclonal antibody was no longer being made commercially. B. henselae specific FISH probes have been designed and validation of FISH probes are in-progress. IHC is also in- progress. All qPCR and ddPCR have been completed at this time and samples are waiting for FISH and IHC analysis.

Research Update End-yr 2 CHF 02528: Developing a Next Generation Sequencing Diagnostic Platform for Tick-Borne Diseases
Diagnostic tests based on the detection of DNA from harmful organisms in clinical samples have revolutionized veterinary medicine in the last decades. Currently, diagnostic panels for several vectorborne diseases (VBDs) are available through universities and private labs in the USA and abroad. However, the vast majority of results from sick dogs are negative, which frustrates veterinarians and dog owners trying to reach a definitive diagnosis.
