The study focused on the Borrelia genus, which includes tick-borne bacteria affecting vertebrates, and aimed to investigate their prevalence in wild animals and ticks in western Japan.
Researchers collected thousands of ticks and animal blood samples to identify various Borrelia species and examined how these bacteria might be transmitted through tick larvae.
Findings revealed multiple tick species carrying Borrelia, with varying infection rates in wild boars, sika deer, and raccoons, as well as seasonal changes in bacterial presence, suggesting a link between the bacterial genotype and the tick species.
