Abstract:
:Blood samples from 382 children between the ages of one and 15 years were tested for anti-chlamydial antibody. A low prevalence of antibody against Chlamydia trachomatis was found among children under the age of seven years. Antibody against the Chlamydial agent C IOL-207 was rare before the age of five years, but was found with increasing prevalence in older children. It is suggested that the mode of transmission of the two agents is different and that C IOL-207 may be transmitted at school.
