FIELD: biochemistry. SUBSTANCE: method is carried out by growing investigated culture on meat-peptone agar. Suspension is prepared from grown cultures and meat-peptone broth, and carnosine are added there. Simultaneously, three control samples are prepared. They are incubated, treated with chloroform and centrifuged. Then test-cultures M. luteus GISK No. 211001 are added in test and control samples and after incubation of prepared mixtures their optical densities are measured. According to difference of optical densities, anticarnosine activity of investigated culture is measured. EFFECT: increased accuracy of diagnostics and prognostication of diseases of microbic etiology. 1 tbl, 2 ex
