POSSIBLE RESERVOIRS OF RICKETTSIA PROWAZEKI IN NATURE,
Abstract
In recent years the appearance of many works has raised the question of revision of the anthroponotic concept of epidemic typhus fever. By complement-fixation reactions, we tested about 1600 head of cattle, horses, and sheep. Some sera were examined parallel with the Weil-Felix reaction and by neutralization of rickettsial toxic substances. Over 400 ticks (Hyalomma asiaticum P. and E. Schl., H. plumbeum Panz., Rhipicephalus turanicus B. Pom., and Dermacentor nuttalli 01.) were also collected and tested virologically. Results of serum analyses and tick examination in Khakass were negative. We also failed to isolate Rickettsia prowazeki from ticks in Kirgizia. Analysis of animal sera gave weak positive results in dilutions of 1:10 in 0.5-3% of cases. Thus, no data were obtained for the presence of natural foci of typhus fever in Khakass and Kirgizia.
