Dogs and horses with antibodies to outer-surface protein C as on-time sentinels for ticks infected with Borrelia burgdorferi in New York State in 2011.
- Journal Article
Summary
The research investigates the use of dogs and horses as indicators for the presence of ticks infected with Borrelia burgdorferi, the bacteria that causes Lyme disease, in different counties of New York State.
Objective of the Research
The primary goal of this research was to better understand the geographic spread of Lyme disease, a debilitating chronic disease caused by the Borrelia burgdorferi bacteria transmitted through tick bites. This study aimed to use companion animals, specifically dogs and horses, as markers for the presence and spread of B. burgdorferi-infected ticks across New York State.
Methodology
- The research utilized samples from 451 dogs and 2100 horses across 50 counties in New York State. These samples were collected by vets due to suspicion of infections or during annual health check ups.
- The collected samples were then sent to the New York State Animal Health Center for further examination.
- The researchers looked specifically for antibodies to an antigen named outer surface protein C (OspC), which is a marker of early infection, detectable from 3 weeks to 5 months post-infection.
Findings
- The researchers found that 23% of the canine samples and 8% of the horse samples had evidence of recent infections with B. burgdorferi.
- In 21 counties, incidence of infection was reported in only one species, either dogs or horses.
Implications
- The results indicate the effectiveness of using dogs and horses as sentinels to identify areas with a high risk of Lyme disease in humans due to the presence of B. burgdorferi-infected ticks.
- The researchers also advocate for these animals to be included in a passive surveillance system that can warn of the spread of Lyme disease.
- By detecting the OspC antigen, the study provides a sensitive, new tool to recognize risks of Lyme disease and potentially control its spread in both animal and human populations.
This study contributes significantly to the control of Lyme disease by providing a practical and efficient method for monitoring the presence and spread of B. burgdorferi-infected ticks through passive surveillance of dogs and horses.
