Oceniono przydatność opracowanego we własnym zakresie odczynu lateksowego do diagnostyki zakażeń wywoływanych przez M. pneumoniae. Stwierdzono wysoką czułość i swoistość tego odczynu w stosunku od odczynu wiązania dopełniacza i odczynu ELISA w klasie immunoglobulin M. Wyniki badań wskazują, że odczyn lateksowy może być wykorzystywany w rutynowej diagnostyce mykoplazmozy jako szybki test przeglądowy.

The usefulness of latex agglutination test prepared in our laboratory for the diagnosis of M. pneumoniae infections was assessed. A total of 628 serum samples obtained from patients with respiratory tract infections were tested by complement fixation test and by latex test, from among them 274 serum samples were additionally tested by ELISA - Ig A / - IgG/ - IgM and by immunoelectroprecipitation test. The highest sensitivity and specificity was displayed by the latex test in relation to ELISA when determining mycoplasmal antibodies of IgM class (respectively 82,1% and 89,6%) and to the complement fixation test (81,0% and 89,0%). Positive latex test results in our investigations were associated only with the presence of IgM antibodies and were not dependent on the Ig A and IgG antibody classes. The latex agglutination test may be used in routine serodiagnosis of mycoplasmosis under condition that the results obtained in this test will be confirmed by the complement fixation test or ELISA.
