[Multifactor analysis of ciprofloxacin action on the content of various classes of antibodies to EV vaccine fraction 1 and hemagglutinins].

The action of ciprofloxacin on the content of antibodies of the IgG, IgM and IgA classes in the blood serum of mice immunized by the EV vaccine fraction 1 as well as on the content of hemagglutinins to sheep erythrocytes was studied in a multifactor analysis with the use of a wide variety of the doses and administration times. In the doses corresponding to the average therapeutic ones ciprofloxacin increased the content of the antibody classes and especially that of IgG. When administered prior to the immunization the antibiotic stimulated the production of the hemagglutinins.
