[Use of the ELISA immunoenzyme method for the detection of the causative agent of tularemia].
The conditions of the enzyme-linked immunosorbent assay (ELISA) for the detection of Francisella tularensis were worked out. In the study of 27 strains differing in their biological characteristics, the sensitivity of the assay was determined, varying within the range of 1 X 10(4)--5 X 10(4) million cells/ml and exceeding the sensitivity of the currently used methods for the immunodiagnosis of tularemia by 1-2 orders. ELISA also proved to be a highly effective technique for the detection of the specific antigen in the organs of infected animals. The antigen was regularly detected in the organs of white mice, beginning from day 3 after their infection with the minimal doses of F. tularensis. The method may be recommended both for the identification of isolated cultures and for the early diagnosis of tularemia infection.
