Abstract:

The isolation of this virus from the blood of patients or from ticks, through injections into the peritoneal of avitamitic guinea pigs, is easy. The transvariable transmission of the virus in ticks Dermacentor silvarum is to the second generation as a rule. By using the rabbits as hosts for the ticks, in various stages of their development, first effects can be obtained identical to those in man with slight exceptions. In blood of patients and reconvalescents, of tick fever, is observed agglutinins to Proteus OX19, OX2 and OXK with OX19 dominating. Agglutinins to 2 or all of these at once is rare. The average titer to OX19 is 1400 - 1800, and 120 to OX2 and OXK. Only 3 of those bitten actually contacted the disease. Others who suffered ill effects constituted 13.
