Randomized trial investigates Rickettsia species presence in ticks and fleas from Vietnam's environment, indicating potential health risks.

This study aims to investigate the presence and distribution of Rickettsia species in environmental ticks and fleas in Vietnam.
Ticks and fleas collected using dragging, light traps, and carbon dioxide traps.
Molecular screening for Rickettsia species performed using real-time PCR targeting the 17kDa antigen gene.
Positive samples analyzed with species-specific real-time PCR and multilocus sequence typing (MLST).
A total of 758 arthropods collected, including 748 ticks and 10 fleas.
Minimum field infection rate of Rickettsia spp. in ticks was 2.94% (22/748); prevalence in fleas was 50% (5/10).
Rickettsia felis detected in 9 larval tick pools and 2 individual fleas with no other Rickettsia species identified.
