Qh. Liu et al., EVIDENCE FOR A HIGH PREVALENCE OF SPOTTED-FEVER GROUP RICKETTSIAL INFECTIONS IN DIVERSE ECOLOGIC ZONES OF INNER-MONGOLIA, Epidemiology and infection, 115(1), 1995, pp. 177-183
A 3-year study of spotted fever group rickettsial ecology in Inner Mon
golia revealed that nearly half of the human population tested had ant
ibodies to Rickettsia sibirica detected by complement fixation test. I
nfected persons, ticks and a high proportion of seropositive livestock
, and wild rodents were found in all five vegetation zones (desert, st
eppe, forest, forest-grassland and grassland).
