Vector Borne Disease Diagnostic Laboratory

**Latest Changes in the VBDDL, CVM-NCSU, Oct 2014

Detect exposure to multiple pathogens using comprehensive molecular and serological panels rather than targeting one disease and potentially overlooking co-infecting or hidden disease processes that may affect treatment or management strategies in your patients. Since January 2013, we have offered Canine or Feline Comprehensive Panels that detect antibodies against 12 known species and detect the presence, within circulating blood, of disease-causing organisms from 5 pathogenic genera!  We offer this $385 value at a greater than 50% discount. Results of recent studies support the use of PCR and serological assays in parallel as likely to increase the detection of infection with or exposure to Canine Vector Borne Diseases up to 60% in some populations of vector exposed dogs. (Maggi RG, Birkenheuer AJ, Hegarty BC, Bradley JM, Levy MG, Breitschwerdt EB. 2014. Advantages and limitations of serological and molecular panels for the diagnosis of vector-borne infectious diseases in dogs. Parasites & Vectors. 7:127. The response from our clients has been appreciated.

Efforts are also underway to improve the sensitivity of our PCR assays. The VBDDL has developed a quantitative PCR (qPCR) for detection and discrimination of spotted fever and typhus group Rickettsia spp. in diagnostic samples. Since converting to the new qPCR, the VBDDL has detected R. rickettsia in 5 dogs; R. amblyommii in an A. amblyomma tick; and R. honei in a human sample from Australia. Improvements in Bartonella PCR have made it possible to detect B.clarridgeiae and B.rochalimae in diagnostic samples. Validation of Ehrlichia and Anaplasma sp assays are proving successful as well. Our Babesia PCR has confirmed detection of B.conradae as well as B.canis, B.gibsoni, B.odicoilei, and B.coco. The addition of hemotropic mycoplasma to the panel has resulted in the detection of numerous M.haemominutum, M.hemoparvum, M.hemocanis and M.hemofelis (in descending order of prevalence).

Samples to send: paired serum and EDTA whole blood (2mls each). To submit samples for testing through our lab, please download our most recent TEST REQUEST FORM with instructions.

Statement of Intent - VBDDL, IPRL 3-13-2011

It is our intention to give each case with which we become involved the highest quality and attention possible. We will handle the sample with care and appropriate speed to obtain the most informative and accurate result. We intend to collect and utilize descriptive information imparted with that sample (address, age, breed, sex, history) in ways that reveal the useful and pertinent context for the diseases we study without using information in any way that might insult or harm the animal, owner, or veterinarian concerned.

Legal Notice

The focus of the NCSU VBDDL is research to benefit animal health.  It is our intention to provide quality answers to diagnostic questions.  The assays, antigens and controls used are developed and validated as a component of our research. We reserve the right to modify methods or reagents as needed to achieve the best analysis possible without reliance on any proprietary method or reagents.
