[Common antigen for serological detection of urinary tract infections during pregnancy (author's transl)].

All urinary tract infections cannot be safely detected by bacterial urine testing during pregnancy. Therefore, the question was studied whether detection of antibody to the "enterobacterial common antigen" (ECA) might be important to screening of pregnant women for urinary tract infections. Tests were applied to 202 sera obtained from 42 pregnant women with urinary tract infection, with pathological titres having been recorded from 21.8 per cent.--Detection of antibody to ECA, consequently, is not believed to be helpful in improving diagnosis of urinary tract infections during pregnancy.
