　 Cells in the cytology specimen were collected for the PCR analysis. A 221 base pair band was obtained, and the sequence analysis was consistent with E. gingivalis. 　
　 　 　 　

　

 　 Prolonged use of the IUD provides a chance for anaerobic microbes to grow. Both A. israelii and E. gingivalis are the anerobic normal flora of the oral cavity. Infection was apparently transmitted by oral sex.
