Study on Chlamydia trachomatis infection among students and pregnant women in Japan: a step toward developing a reliable method for sexual behavior study

Tohoku J Exp Med. 1999 Feb;187(2):189-92. doi: 10.1620/tjem.187.189.


2450 sera from students and 5215 sera from pregnant women were examined for the presence of Chlamydia trachomatis (CT) antibody. CT antibody positive rates were less than 5% with the students and 24.5% with the pregnant women suggesting the latter is significantly higher than former. The results provided a base for discussing possibility of using CT infection as a reliable method for studying sexual behavior.
