Molecular Epidemiology and Genetic Diversity of Orientia tsutsugamushi From Patients and Small Mammals in Xiangyun County, Yunnan Province, China

open access: yesVeterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Scrub typhus is caused by Orientia tsutsugamushi (OT). In this study, the detection rates of OT in patients and small mammals were 28.13% (18/64) and 13.98% (13/93), respectively. Nine full‐length 56‐kDa TSA genes were identified, comprising four distinct genotypes: Karp‐like (n = 3), Kato‐like (n = 3), Gilliam (n = 2), and TA763 (n = 1). Recombination
