Summary
A new real-time PCR assay detects the Anaplasma bovis-like agent in ticks. This research found a low prevalence of this agent in Dermacentor ticks across the United States.
Area of Science:
- Veterinary microbiology
- Molecular diagnostics
- Parasitology
Background:
- Anaplasma bovis is an important tick-borne pathogen affecting livestock.
- Limited diagnostic tools exist for detecting Anaplasma bovis-like agents in wildlife reservoirs.
Purpose of the Study:
- To develop and validate a real-time PCR assay for Anaplasma bovis-like agent detection.
- To determine the prevalence of the Anaplasma bovis-like agent in Dermacentor ticks.
Main Methods:
- Real-time PCR assay development and validation.
- Screening of 672 Dermacentor spp. tick samples collected nationwide.
- Molecular detection of Anaplasma bovis-like DNA.
Main Results:
- A sensitive and specific real-time PCR assay was successfully developed.
- The Anaplasma bovis-like agent was detected in 0.1% of the tested ticks.
- Geographic distribution of positive ticks across the United States was noted.
Conclusions:
- The developed real-time PCR assay is a valuable tool for Anaplasma bovis-like agent surveillance.
- Epidemiologic surveys for this agent in tick populations can be enhanced.
- Potential implications for understanding agent transmission to humans.
