[Evaluation of usefulness of OWD and OIEP in diagnosis of epidemically occurring infections caused by Mycoplasma pneumoniae].
Blood serum samples of 3593 persons clinically suspected of infection with Mycoplasma pneumoniae were tested. Of these, patients with pneumoniae constituted 66.5%, upper respiratory tract infection--24.0% and with symptoms localized outside the respiratory system--9.5%. These studies were performed by application of complement fixation test (OWD) and immunoelectroprecipitation (OIEP) methods, accepting as a diagnostically significant--titer 1:60 or higher and/or occurrence in OIEP reaction with serum diluted 1:2 or more. Among patients studied prevailed children in the age of 3 to 16 years (61.6%). Mycoplasmosis was detected in these patients in 1071 out of 2236 cases (47.9%). Compatible results in both tests were obtained in 90.6% patients, whereas OWD only in 3.0% and OIEP only in 6.4% cases. Simultaneous application of both tests increased detectability of infections caused by M. pneumoniae by 3% in relation to OIEP and by 6.4% in relation to OWD.
