Résumé
Flea-borne rickettsioses have been limitedly explored in the Indian sub-Himalayan belt, including the North Eastern Region (NER) of India. This study investigates the presence of rickettsiae hosts and their probable pathogens in the disease-endemic hilly state of the NER of India. Entomological surveys were carried out in disease-reporting localities in a hilly state in India. Fleas collected from domesticated animals were processed for detection of a Rickettsia-specific 17-kDa gene. Sequence analysis revealed Rickettsia felis in six flea pools (40%), Candidatus Rickettsia senegalensis in two pools (13.3%) and Rickettsia asembonensis in one pool (6.6%). Our findings suggest Ctenocephalides felis, Ctenocephalides canis and Pulex irritans as potential carriers of R. felis and R. felis-like organisms in India.

BACKGROUND
Flea-borne rickettsioses have been limitedly explored in the Indian sub-Himalayan belt, including the North Eastern Region (NER) of India. This study investigates the presence of rickettsiae hosts and their probable pathogens in the disease-endemic hilly state of the NER of India.
METHODS
Entomological surveys were carried out in disease-reporting localities in a hilly state in India. Fleas collected from domesticated animals were processed for detection of a Rickettsia-specific 17-kDa gene.
RESULTS
Sequence analysis revealed Rickettsia felis in six flea pools (40%), Candidatus Rickettsia senegalensis in two pools (13.3%) and Rickettsia asembonensis in one pool (6.6%).
CONCLUSIONS
Our findings suggest Ctenocephalides felis, Ctenocephalides canis and Pulex irritans as potential carriers of R. felis and R. felis-like organisms in India.
