[Comparative study of ixodes ticks on their infection with tularemia pathogen using biologic and serological assays].

The paper presents the results of a long-term comparative study of the infection of Ixodes tick imagoes with the pathogen of tularemia by using the biological assay and antibody neutralization test. The infection rates determined by both methods were found to be identical or close. If there was a difference in the rates in some years, it was not statistically significant.
