Molecular Detection and Phylogenetic Analysis of Tick-Borne Pathogens in Ticks Collected from Horses in the Republic of Korea.
Abstract: The horse industry has grown rapidly as a leisure industry in the Republic of Korea (ROK) in parallel with an increased demand for equestrian activities. As a result, there has been an increase in horse breeding and equestrian population and potential exposure to ticks and their associated pathogens. To provide a better understanding of the potential disease risks of veterinary and medical importance, a study was conducted to determine the geographical distribution and diversity of ticks collected from horses and vegetation associated with horse racetracks/ranches throughout the ROK. This included a survey of five associated common pathogens, , , spp., , and . A total 9220 ticks were collected from horses and associated pastures. Ticks were identified to species, stage of development, and sex. Two species of ticks, (99.9%) and (0.1%) were identified. Two of the target pathogens, and spp., were detected in 5/1409 tick pools (0.35%) and 4/1409 pools (0.28%) of , respectively, both of which are zoonotic pathogens of medical importance. The results of 16S rRNA phylogenetic analysis of showed a close relationship to strains distributed in China, USA, Germany, Italy, Turkey, and Poland. spp. showed a close relationship, based on 16S rRNA gene, to the strains reported from the USA ( and ) and Japan ( and ). These results provide information about the potential risks of veterinary and medical importance and the development of mitigation strategies for disease prevention.

Summary
This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.
The research article discusses a study conducted on identifying ticks and their pathogens collected from horses in the Republic of Korea, given the recent growth in the horse industry. This study helps in understanding the potential risks these ticks pose to veterinary and medical fields.
Objective and Scope of the Research
- The research aimed to identify and analyze the different species of ticks and the common pathogens they carry that may have been collected from horses and associated pastures in the Republic of Korea.
- The study came about due to the rapid growth of the horse industry in Korea, which has resulted in an increase in horse breeding and equestrian activities, leading to potential exposure to specific ticks and their associated pathogens.
- In order to better understand the potential health risks these ticks can bring, the study focused on the geographical distribution and variety of ticks in these regions.
Methodology of the Study
- A total of 9220 ticks were identified regarding their species, stage of development, and sex. They were collected from horses and associated vegetation near horse racetracks and ranches.
- The study included a survey of five common pathogens detected in ticks which may pose risks to both animal and human health.
- Ticks found were majorly of two species – 99.9% belonging to one species and the remaining 0.1% to another species.
Findings from the Research
- Two pathogens of medical importance were detected with the help of pool testing in ticks of one particular species.
- These pathogens are also known to be zoonotic, indicating that they can be transmitted from animals to humans.
- To understand the global perspective, the researchers performed a 16S rRNA phylogenetic analysis on the pathogens detected. They found a close relationship between the pathogens distributed in several countries like China, USA, Germany, Italy, Turkey, Poland, and Japan.
Impact of Study
- The outcomes of this study impart vital information regarding potential risks that ticks and their associated pathogens may present to health in veterinary and medical fields.
- Based on these findings, appropriate strategies for disease prevention can be developed and implemented.
