COMPARATIVE ASSESSMENT OF EFFICIENCY OF “DIRECT” METHODS FOR UREAPLASMOSIS DIAGNOSIS IN PREGNANT WOMEN

Aim. To compare the diagnostic value of some “direct” methods for diagnosis of ureaplasmosis in pregnant women. Materials and methods. The variant of polymerase chain reaction and direct immunofluorescence were used to examine 112 Ur. urealyticum-infected pregnant women, including 53 women with the level of colonization < 104 CFU/ml and 59 women with the titer > 104 CFU/ml. The group of comparison consisted of practically healthy women with negative results of bacteriological investigation for ureaplasmosis. Results. In the studied material of all ureaplasma-infected (by bacteriological test data) pregnant women, DNA fragments of the pathogen were detected; in 86,44 % of women with a high ureaplasma titer (by bacteriological test data), DNA of the pathogen in the concentration of 5,0·104 DNAcopies/ml and more was registered. The same high concentrations of DNA were stated in 43,4 % of the examined women with ureaplasma titer (by bacteriological test data) lower than etiologically significant values. Direct immunofluorescence was less effective. Conclusions. For laboratory diagnosis of pregnant ureaplasmosis, it is necessary to combine bacteriological method with PCR that permits to diagnose ureaplasmosis more effectively.
