| Abstract: | The study of the persistence potential of 64 F. tularensis strains isolated from different sources was carried out. The wide spread of the antilysozyme, antilactoferrin and anticomplementory activities of F. tularensis were detected. F. tularensis, isolated from ticks and water, were characterized by the highest level of the expression of antilysozyme activity, while anticomplementory and antilactoferrin activities of the infective agents were characteristic of those microorganisms which were isolated from rodents and their excrements. |
