[Pilot study for radiometric detection of mycobacteria in lymph nodes altered by tuberculosis in slaughtered animals]

30 lymph nodes with tuberculous changes from slaughter animals were investigated, comparing radiometric and usual cultural methods for presence of mycobacteria. Mycobacteria were isolated with help of radiometric method (BACTEC 460-TB) from 24 lymph nodes ("sensitivity" 96%, "specificity" 83.3%), and with help of usual cultural method from 22 lymph nodes ("sensitivity" 88%, "specificity" 62.5%). The radiometric method is suitable for isolating of mycobacteria in veterinary medicine diagnostic also.
