RESUMO
Amoebic trophozoites were identified in the cervicovaginal smear of a U.S. patient without travel history at the time of intrauterine device (IUD) removal. Subsequent morphologic analysis and DNA sequencing identified a mixed cervicovaginal colonization of the female genital tract with both Entamoeba gingivalis and Entamoeba polecki in association with Actinomyces species bacteria. This highlights to the potential for colonization of the genital tract with E. gingivalis, particularly in association with IUD placement, and represents the first report of E. polecki in this context.

Entamoeba gingivalis is a common parasite of the human buccal cavity whose rare appearance in Papanicolaou-stained sputum smears may be missed. Two such cases are described, including the morphologic features of this ameba. The trophozoites were seen to phagocytize leukocytes as well as red blood cells, in distinction to E. histiolytica, which phagocytizes only red blood cells and also can cause pulmonary abscesses. The concomitant finding of Actinomyces sp. organisms in one patient reinforces the possible symbiotic relationship between the two organisms, as has been suggested for their appearance in other extraoral sites, such as the female genital tract.
