Experimental borreliosis in guinea pigs caused by ticks' bites assumed two forms--typical and mild, the latter being encountered in 40% of cases. Mild form significantly differs from the typical one in some indices of borreliemia: intensity, duration, time of onset and cessation, absence of fluctuations in the number of borrelia. The form is not easily diagnosed by the analysis of animal blood preparations, which should be taken into consideration in experimental and clinical practice. In mild form of borreliemia the agent should be searched for in the blood of guinea pigs daily from days 6 to 12 after the infection, with the following control till day 20.
