Boutonneuse spotted fever is a summer and late spring infection caused
by Rickettsia Conorii mainly in Middle East countries adjacent to the
mediteranean coast (1). Malignant forms have been described in debili
tated patients associated with prerenal azotemia, acute tubular necros
is or renal vasculitis (2, 3). We report for the first time to our kno
wledge, the association of an extracapillary glomerulonephritis with a
Boutonneuse spot ted fever. This observation suggest that Rickettsia
Conorii, as other bacteria, could participate to the development of gl
omerulonephritis.
