Four of the five genotyped eye swabs yielded trachoma genotype Ba, and the other genotype J. Two hundred twenty-two specimens (50.6%) were successfully genotyped.

Therefore, <jats:italic>C. trachomatis<\/jats:italic> genotypes in UGT specimens from young children can be informative as to whether the organism has been acquired through sexual contact. We suggest inclusion of <jats:italic>C. trachomatis<\/jats:italic> genotyping in guidelines examining the source of sexually transmitted infections in young children in areas where trachoma genotypes may continue to circulate, and continued surveillance of UGT <jats:italic>C. trachomatis<\/jats:italic> genotypes.<\/jats:p>\n
