About

Barbara Qurollo is a research associate professor at North Carolina State University College of Veterinary Medicine. She obtained her Doctor of Veterinary Medicine (DVM) degree from Colorado State University and completed an internship in Emergency Medicine and Critical Care in Milwaukee, Wisconsin. Following her internship, she spent three years studying vector-borne diseases in companion animals as a Postdoctoral Research Scholar at NC State's College of Veterinary Medicine. Her research efforts are focused on vector-borne disease in wildlife and companion animals, as well as on developing improved methods for detecting diseases across wildlife, pets, domesticated animals, and humans. She is affiliated with the North Carolina Veterinary Medical Association, the Comparative Medicine Institute at NCSU, and the International Society for Companion Animal Infectious Diseases.

• Development of a Multiplex Droplet Digital PCR Assay for the Detection of Babesia, Bartonella, and Borrelia Species

  Pathogens · 2021-11-11 · 23 citations

  articleOpen access

  We describe the development, optimization, and validation of a multiplex droplet digital PCR (ddPCR) assay for the simultaneous detection of Babesia, Bartonella, and Borrelia spp. DNA from several sample matrices, including clinical blood samples from animals and humans, vectors, in-vitro infected human and animal cell lines, and tissues obtained from animal models (infected with Bartonella and/or B. burgdorferi). The multiplex ddPCR assay was able to detect 31 Bartonella, 13 Borrelia, and 24 Ba…

• <i>Bartonella rochalimae, a</i> newly recognized pathogen in dogs

  Journal of Veterinary Internal Medicine · 2020 · 20 citations

  BACKGROUND: Bartonella spp. comprise a genus of bacteria that frequently cause persistent, often subclinical infection. Although many Bartonella spp. have been implicated in a variety of clinical presentations, Bartonella rochalimae has yet to be documented in association with a clinical presentation other than infectious endocarditis (IE) in dogs. OBJECTIVES: To document a spectrum of clinical presentations accompanied by mild hematological abnormalities in B rochalimae-infected dogs from the U…

• An Improved Point-of-Care ELISA for the Diagnosis of Anaplasmosis and Ehrlichiosis During the Acute Phase of Tick-Borne Infections in Dogs

  Topics in companion animal medicine · 2022 · 19 citations

  Veterinarians often test for serologic evidence of vector-borne infections in sick dogs presenting with clinical signs or to screen for subclinical chronic infections. Additional peptide targets for the detection of antibodies to Anaplasma phagocytophilum, Anaplasma platys, and Ehrlichia canis were added to an existing point-of-care (POC) ELISA test (SNAP 4Dx Plus Test, IDEXX Laboratories, Westbrook, ME). This second-generation, multi-analyte test detects Dirofilaria immitis antigen and antibodi…

• Targeted Next-Generation Sequencing for Comprehensive Testing for Selected Vector-Borne Pathogens in Canines

  Pathogens · 2022-08-24 · 17 citations

  articleOpen access

  The standard for detecting vector-borne pathogens is real-time PCR (rtPCR). However, this requires many individual tests to obtain an accurate diagnosis. The purpose of this study was to develop and validate a targeted next-generation sequencing (NGS) assay for vector-borne pathogens. Pathogen target regions were amplified via PCR using two primer pools that were developed in conjunction with ThermoFisher Scientific, and barcoded DNA libraries were prepared and sequenced with the Ion Torrent S5…

• Comparison of Anaplasma and Ehrlichia species–specific peptide ELISAs with whole organism–based immunofluorescent assays for serologic diagnosis of anaplasmosis and ehrlichiosis in dogs

  American Journal of Veterinary Research · 2020 · 17 citations

  1st authorCorresponding

  OBJECTIVE: To compare the performance of 5 synthetic peptide-based ELISAs with that of 3 commercially available immunofluorescent assays (IFAs) for serologic diagnosis of anaplasmosis and ehrlichiosis in dogs. SAMPLE: and 1 uninfected control dog in previous studies. PROCEDURES: The species-specific seroreactivity, cross-reactivity with the other tick-borne pathogens (TBPs), and diagnostic sensitivity and specificity were calculated for each assay and compared among assays. RESULTS: All serum sa…
