Hypothesis
What is the seroprevalence of Toxoplasma gondii in wild boar and Korean water deer in the Republic of Korea?
Conclusion
Toxoplasma gondii is endemic in both wild boar and Korean water deer, with seroprevalence rates of 34.9% and 29.9%, respectively.
Supporting Evidence
- T. gondii seroprevalence was 34.9% in wild boar and 29.9% in Korean water deer.
- Seroprevalence was highest in winter for both species.
- Wild boar seroprevalence decreased significantly in 2020 compared to previous years.
- Body mass in wild boars was positively correlated with T. gondii seroprevalence.
Takeaway
This study found that many wild boars and Korean water deer in Korea have a parasite called Toxoplasma gondii, which can be harmful to humans.
Methodology
Blood samples were collected from wild boars and Korean water deer over four years and tested for Toxoplasma gondii antibodies using ELISA.
Potential Biases
Potential bias from opportunistic sampling and the reliance on legally hunted animals.
Limitations
The study's sample sizes varied by season and year, which may affect the results.
Participant Demographics
Wild boar (n=487) and Korean water deer (n=452) from nine provinces in Korea.
