Ticks and tick-borne pathogens pose a significant threat to human animal health, yet the diversity prevalence of microorganisms in karst regions remains inadequately explored. In October 2023, total 274 Rhipicephalus microplus ticks were collected from livestock Guizhou Province, which boasts largest area China. Pathogen identification was subsequently performed using PCR amplification, Sanger sequencing, phylogenetic analysis. High microbial noted, with five bacterial species order Rickettsiales detected, including those genera Rickettsia (family Rickettsiaceae), Anaplasma, Ehrlichia Anaplasmataceae). The overall infection at least one pathogen remarkably high 94.5%. highest positive rate observed for Candidatus jingxinensis 90.9%. A novel species, provisionally designated as carsus, identified 16.8%. addition, Anaplasma marginale, Ehrlchia minasensis canis detected 15.3%, 4.7% 1.5%, respectively. co-infections involving two or three rickettsial 34.3% ticks. These findings highlight agents area, underscoring need enhanced surveillance effective tick control mitigate disease risks both humans livestock.
