Rickettsialpox — a rare but not extinct disease: review of the literature and new directions

Rickettsialpox is an urban zoonosis caused by Rickettsia akari. To date R. akari is the only well-characterized mite-borne member of the spotted fever group. It is transmitted by the mouse mite, Liponyssoides sanguineus, commonly found on peridomestic rodents. While the disease was first discovered...
