Abstract
<i>Rickettsia parkeri</i>in Uruguay
Highlights
To the Editor: During 1990 in Uruguay, a rickettsiosis in the spotted fever group was presumptively diagnosed for 3 patients who had fever, an initial small maculopapulous lesion at the site of a tick bite on the scalp, and subsequent regional lymphadenopathy
A recent investigation demonstrated DNA of R. parkeri in A. triste ticks collected from humans and animals, indicating that this rickettsia could be the pathogenic agent of spotted fever group rickettsioses in Uruguay (5)
In the United States, where A. maculatum ticks infected with R. parkeri have been reported since the 1930s, the role of this rickettsial agent as a human pathogen was confirmed only recently (3)
