Rickettsiae of the spotted fever group in Hungary.

Folia parasitologica, 1980
Rickettsiae were detected by haemocyte test in 7.2% of Dermacentor marginatus and 4.7% of D. reticulatus ticks collected in Hungary. Six strains of rickettsiae were isolated from positive specimens. These rickettsiae according to CFR are closely related, probably identical with R.
