Genital tract infection with entamoeba gingivalis in intrauterine device users

The prevalence of Entamoeba gingivalis in the genital tracts of 100 intrauterine device [IUJD] users and 20 non-IUJD users was determined by direct smear and cultivation on a modified antibiotic-free diamond's TYL-S-33 medium. It was found that 11% of IUD users harbored the parasite, whereas no amoeba was found in any of the specimens of the non-users. The probable factors enhancing genital tract infection with E. gingivalis and the possible role of the amoeba in that unusual habitat are discussed
